When Lightning Strikes

Equipment Review

I've often admired some amazing photographs of lightning and although I've read plenty on the technique of how to achieve such shots I've never had any success myself. All my attempts have been a complete disaster even when I've know the shutter was open when the lightning flashed.

It seems the generally accepted technique is to put the shutter speed on Bulb and leave it open for a certain length of time. Of course it goes without saying that you need to have your camera securely mounted on a sturdy tripod and use use a cable release too. However, even after that, picking the right exposure can be tricky depending whether your shooting in the day or night and knowing where to focus can be problematic too, especially if it's dusk or night and you have some foreground interest too. Many of the shots you see online are purely of the lightning, but as landscape photographers we wish to incorporate other aspects of the landscape within our composition, not just the lightning.

The Lightning Trigger

About a couple of years ago I became aware of a device called the 'Lightning Trigger' made by a company called Stepping Stone Products, LLC in Colorado. Thisfirst came to my attention while watching Steve Kossaks DVD on Death Valley. Steve also posted a review of the Lightning Trigger on the Luminous Landscape web site which can be viewed here. The Lightning Trigger is a small rectangular shaped device, rather similar in size to one of those portable 2-1/2" hard drives, that slots onto the hotshoe of your DSLR and has a cable that plugs into the remote cable socket. It comprises a sensitive optical flash sensor that responds to lightning flashes which it can supposedly detect at distances of up to 20 miles away in day light and 40 miles at night. Often our eyes and brain can only visualise a single flash of a lightning strike, but each strikes can last several hundred milliseconds and comprise multiple strikes occurring around 40 milliseconds apart. The Lightning Trigger depends on this and reacts to the first strike and opens the shutter enabling following strikes to be captured. All this depends on the reaction speed of the device and how quickly your camera responds, but most cameras react within 90 milliseconds and some are almost instantaneous.

I must admit I was sorely tempted by such a device as I have been travelling backwards and forwards to the Lake Albert region of Uganda for the last 4 years, and where we are often treated to spectacular storms during the rainy season. However at $329 and only available from the US, by the time I'd paid VAT and import tax this would be a very expensive purchase indeed. My desires to own such a device were therefore put on hold.

The AEO Lightning Strike

Just over a year ago I found a very similar device available on eBay called the AEO Lightning Strike. This was developed by a father and son team of the Adams Electo-Optics Photo Company and for all intents and purposes seemed almost identical to the Stepping Stone Lightning Trigger. Once more, it was considerable cheaper at only $100, which included shipping to the UK. At just over 60 quid at the time I thought this was worth a punt and duly clicked the buy-now button. It arrived reasonable well packaged several days later in a plain brown box containing just the Lightning Strike and one printed page of rather brief instructions. The device was rather plain simple looking affair, housed in a solid black plastic case, with a large on-off button in the centre of the top, with a small red LCD next to it. You have to order a device specific to your camera, so the 8-inch lead on mine had a canon fitting. I wouldn’t say the device looked crude, a little unrefined is perhaps a fairer description, as the remote socket plug doesn’t look the best quality, but with a bit of wiggling around it fits. It’s certainly a solid construction however. The underside has a plastic hotshoe fitting centrally mounted and a cover that houses a 9v rectangular battery compartment. The front a has red plastic screen housing the detector.

First Attempts

That was last May (2010) and sadly until then the Lightning Strike has sat in my Camera bag waiting for an opportunity to use it. Sadly no storms of note occurred around my home back in the UK, but last night in Uganda, the Lightning Strike was christened. A huge storm passed nearby the rig I have been working on and the distant lightning seemed too perfect to resist. The instructions included with my device suggested using shutter priority and exposure from 1/8 to 1/4 of a second, set to manual focus and focus at infinity. However, I had the rig in my foreground so focused on that, and set the speed to 1/4. However, that resulted in most of my shots being shot wide open at F2.8, which although resulted in the derrick being sharp, the lightning in the distances was rendered a little soft. However, the device worked pretty dam well and I have to say I’m impressed with my first attempts. Next time I’ll try aperture priority and use F8 or F11 if I have something in the foreground. You don’t really have to be worried how long your exposure is going to be as long as you don’t exceed the 30 second limit for Av and Tv modes.

New Models

The AEO Lightning Strike is now only available in version II, which has had a bit of a make-over since my version, and includes a battery and you can fit optional plug-in cables. Sadly with the improvements has come a price hike and it’s now $132; quite a bit more expensive but looking at the many videos on You Tube it’s certainly appears to be a more refined product. The company has obviously met with some success and they now offer 2 additional models, one which includes a pelican case and manual override of sensitivity (LS Trigger Plus), and a professional model (AEO Multi-Trigger Pro) which includes a 10m motion sensor. The aren’t cheap however, and currently retail for $232 and $360 respectively so are probably only for professional storm chasers!

Alternatives

A similar device called the Strike Finder can be purchased from here, which currently retails at around $125. The site also includes a nice video of you the trigger in action in a real storm and the results it produces. There is also the PatchMaster Lightning Trigger that can be obtained from a mere $107, and they also do a version which includes a sound trigger for $152. PatchMaster products seems to originate from Turkey and I did find a few negative reviews around where they have been dead-on-arrival, but at that price they certainly seem worth a try.

Summary

I’m very pleased with my AEO Lightning Strike trigger. It works well and my first attempts are quite pleasing. It’s opened up another area of photography for me to pursue and will hold a regular place in my camera backpack from now on. If I had anything to criticize or to say to the makers of these devices it’s the batteries, 9v batteries are an awkward size, and not one we photographers tend to carry around in out kit bags, 4 x AA would be a much better option, but I guess that would take some design changes. All in all there certainly appears to be more choice of lightning triggers around now, making this a more affordable option for the amateur photographer.

New Prototype 200-400mm f/4.0 Zoom Lens goes on Show from Canon

Equipment Announcement

“LAKE SUCCESS, N.Y., February 7, 2011 – Canon Inc. today announced the development of a new super-telephoto lens, the EF 200-400mm f/4L IS USM EXTENDER l.4x, for use with all EOS SLR cameras. A prototype of the new lens will be exhibited at the CP+ tradeshow, held in Pacifico Yokohama, from February 9 - 12, 2011.”

Much to everyone's surprise Canon announced a whole host of stuff yesterday including two new entry level DSLR’s, two new flash units, and upgrades to their wildlife long focal length specialist lenses. The latter comprise the EF 500mm f/4.0 MII and the EF 600mm f/4.0 MII, both of which are expected to be commercially available some time in March, but as you’d probably expect these are going to be very, very expensive and as such only available to serious pro’s and those blessed with wads of spare cash.

However, what really caught my eye was the announcement of a prototype EF 200-400mm f/4.0 IS USM EXTENDER 1.4x lens. That’s some title!  Nikon wildlife photographers have long since been extolling the virtues of the Nikon 200-400mm f/4 AF-S lens which also received an upgrade last year. This is a lens favoured by British wildlife photographer Andy Rouse and is generally accepted as just about the best multipurpose, wildlife zoom lenses around. It’s also a gap in the market place that Canon had failed (as yet) to match. Canon do of course have their EF 100-400mm f/4.5-5.6mm IS USM lens ( one of which which I own), but this design is getting quite long in the tooth and whilst it performs admirably on sensors sizes up to 12mp, todays 21mp plus sensors highlight it’s short comings in the digital age.

If you examine the press release picture above you can’t help but notice that peculir looking bulge on the left side rear of the lens. This houses the in-built 1.4x extender, and has a lever just above to engage or disengage the extender elements. The 1.4 extender can boost the zoom range from 200-400mm to 280-560mm. On an APS-C sized sensor then this would be the equivalent of a staggering 448-896mm! However, don’t get your hopes up as Canon failed to state whether this configuration will autofocus on the semi-pro and consumer bodies. The new lens will feature Canon’s high-performance Image Stabilizer technology and advanced optics materials such as fluorite crystal to provide top notch optical performance.

You may also notice the camera has a fixed tripod collar, 3 stabilization modes and also features a Focus Pre-set button. All new stuff.

A a wildlife photographer this sounds like a dream lens and one I’d truly love to own, however it is just a prototype and still obviously at the development stage. I just hope that when it does eventually hit the market it’s not going to be priced so ridiculously that photographers like myself will never be able to afford it. Maybe I am just dreaming though!

Tripod Woes

Equipment Failures

I have had my fair share of disasters in the past with photographic equipment. Usually it’s odd items like scratched or broken grads and lost lens caps but I also have had my tripod blown over at Robin Hood’s Bay damaging my EF 24-105mm lens and a fall in the field in Africa which required a new IS unit to my EF 100-400mm zoom lens. Fortunately in both cases I was insured and the bulk of the repairs were covered.

Recently however, I had a rather an odd mishap and lost (yes lost!) a leg from my tripod. This was from my much prized Gitzo GT-3541-LS carbon fibre tripod; not a cheap item either and a tripod you expect to be built to the highest of standards too. But I guess you’re wondering how on earth I could loose a leg. Well it’s not quite as difficult as you may think.

For quite some while now my backpack of choice has been the Lowepro Pro Trekker 400 AW which is an excellent backpack and I’ve sung it’s praises in the full review I did here. It features a tripod loops on the front and sides of the backpack which are really just large pockets without a bottom. The top (rim) of each is heavily reinforced so you can just slot two of your tripod legs inside and let third leg rest outside. The the main tripod holder in the centre of the pack also has a couple of straps to secure the tripod further, and has a fold down foot holder although neither of these two features I have thought necessary if you are just walking short distances. Unfortunately that has been to me detriment.

Whilst out with my family on a walk from our holiday cottage in Craster down to the coastal path towards Cullernose point we got caught in a downpour. Not just any old downpour mind you, a really hooly. The weather turned from blustery but sunny  to wild wet and windy in a matter of minutes with the rain sheeting down and blowing almost horizontally. You know the sort. As prepared as we were, it was time for a mad dash back to the cottage where we headed with some urgency.

I had my Lowepro Pro Trekker 400 AW slung over my back with the tripod just sat in the central tripod pocket, not fastened in. It was really blowing and I was concentrating on getting back fast, keeping an eye on my daughter Sophie whilst keeping one hand on my rain hood to stop it being blown backwards. Unbeknownst to me, the action of my quick walking and the motion of my backpack was slowly but surely unscrewing the uppermost joint of my tripod. Until it fell out. You’d think I'd notice it fall, but I didn’t under the conditions and it didn’t hit my legs either. It was only the next morning on inspecting my pack I found I was missing the bottom 3 sections to one of the legs.

Of course I searched the path and rocks several times with my son, but no trace of the offending leg could be found. It had either ended up being washed out to sea or (probably more likely) been picked up by a later passer by. Either way I was left without a tripod.

The prospect of spending the rest of the holiday without the ability to take photographs was just too much and I contemplated driving all the way home to get my back-up. However, in the end a trip to Newcastle’s Metro centre and a purchase of a Manfrotto 055PROB proved the easiest option.

That all happen in August. Today my replacement leg finally arrived from Gitzo, a good 3 months after placing my order for replacement parts. I heard Gitzo could be slow so that was no surprise. A big thank you has to go to Ian Hemingway at
Manfrotto & Gitzo UK Service Centre for  just managing to sort out the correct parts. As it turns out, just about every Gitzo tripod is unique and they seldom share common parts, and even though less than two years old my model had already been superseded.

Today my wallet is a further 142 quid lighter, not to mention the cost of the temporary replacement Manfrotto. It takes just 4 1/2 turns to completely unscrew one of the leg joints on my Gitzo. I can’t be sure, but I suspect I didn’t tighten it fully from the previous shoot, but I’m still amazed it managed to unscrew itself whilst on the back of my backpack.

And the moral to this tale … well make sure your tripod is tightened fully at each joint after every shoot, and secured properly to your backpack no matter how short the walk to the next location.

Wish List for the Canon 5D Mark III

Equipment Editorial

Now that I’ve proclaimed my top ten features I’d like to see in Lightroom 4. I thought I’d do the same for my other weapon of choice, my Canon 5D Mark II. The 5DMII was released back in September 2008, so has now surpassed that 18-24 month period in which camera models are typically superseded by newer and more feature packed versions. The annual Photokina show in Cologne is fast approaching too, which is normally the stage for the major manufacturers to announce their latest and greatest. Having said that, Canon have recently announced several new lenses, a new EOS 60D camera body, and probably stunned the Camera world by announcing the largest ever CMOS sensor at 120 MP. So can we expect anything new, well if you take heed of the latest internet rumours there will probably be no 5D Mark III till well into 2011?

The current 5D Mark II is a fine camera and for many has been proclaimed by many as just about the best camera out there for landscape photographers. There’s no denying it’s been a huge hit both with professionals and serious amateurs alike and in capable hands can produce superb images. It does have it’s ‘Canonesque’ quirks however, many which I highlighted in my article Canon 5D II – One Year On, and I doubt Canon would ever radically change or vary from their basic design, so I seriously doubt many of my wishes will be met. I’m not a huge fan of the video functions, which looking at the 7D and 60D seems to be the headline grabbing features. It’s not that I dislike video features, but just that being a still’s photographer, they are just not on my radar as priority items. Lets get back to basics please. Anyway here are my top ten, in no particular order:

• Built in GPS: this must be a long overdue feature and probably an easy one to implement. There are many GPS tracker devices out there (I have an AMOD AGL 3080) and the prices have dropped significantly in the last year to where you can pick one up for not much over £60, so the hardware addition should not be that expensive. Currently however, getting GPS data back into your RAW file EXIF metadata is still a tad fiddly although can be achieved by free software. I certainly hope Canon don’t take the route of an add on GPS device that sits in the hot shoe, that would be disastrous and no doubt expensive to the consumer. If GPS were in-built this would be an upgrade deciding feature for me.
  
• In-Built HDR processing: a complete wild card this one, but wouldn’t it be nice. If know the purists will always want total control on merging multiple exposures, but I’m sure Canon could come up with something pretty good.
  
• Electronic Level: this feature is present in the new EOS 60D and has been a regular features on competitors cameras for a while, so a must for any new Canon Camera now. At last we’ll be able to ditch the hot-shoe bubble levels, but we need to be able to see this through the viewfinder not just on the rear screen. 
  
• Quicker and Better Focusing: an absolute no brainer here, the current 9-point focusing system is long overdue an update, and many had hoped would have been updated with the 5DMII. The 7D features a 19-point focus system and even the new 60D  sports a 9-points system. Improved focusing in low light would be a big hit too.
  
• Bigger, Better and Brighter Screen: the 5DMII screen was a big improvement over the 5DMI, but I think there is still room for a much, much bigger screen. Wouldn’t it be nice to have one where we can actually use to made subjective decisions on our photographs. Oh and please, please can we have a one-touch button to zoom straight in for a 100% preview!
  
• 3 Stop or greater Compensation: It’s present on the 1D’s and needed on the 5D Mark III. Many photographers are now experimenting with long exposures and filters such as the Lee Big stopper and B+W’s 10-stop filter have greatly extended the landscape photographers day. You can just about see through the 10 stop filters with Live-View in normal light, but forget it in low pre-dawn or evening light. Canon need to take heed of this expanding and popular aspect of photography and allow tLive-view screen compensation so we can compose, focus, and adjust grads even through a 10-stop filter.
  
• User Configurable Auto-ISO: auto-iso is a great feature but it’s a poor implementation of this on the 5DMII. Currently Auto-Iso chooses ISO values between 100-3200. Please let the user specify the upper and lower limits. It seems Pentax can manage this, so why not Canon?
  
• Proper Camera User Settings: again, a great idea but a totally useless implementation.  User settings should be a useful starting point only. If you then adjust the aperture, ISO or shutter speed it should remain at those values. If you (like just about every other photographer I hasten to guess) have probably got got your auto-power off set for a short interval (as we all wish to preserve battery life), then as soon as your camera powers off, your User Settings are set back to their starting values. I don’t know any photographer uses the same settings for every photograph, so why on earth make them work that way? Make them work properly and give us several more!
  
• Ergonomics – Tactile Buttons & Analogue Controls: I know making all buttons alike probably aids the visual appearance of a camera body, but when you are fiddling around in low light they all feel the same and it’s easy to press the wrong one. Tactile buttons would be nice; one’s that feel different and are readily identifiable by touch. They could be alternate sizes, have a textured or imprinted surface. A rubberised and larger DOF button would be a big improvement too; that tiny little button is just too slippery and awkward to locate. I also still have problems pushing down the joy-stick Multi-Control button to access the Quick Control screen, so much in  fact I’ve mapped that to my Set button. I like analogue controls and the Control wheels are great. They just make more sense and are so much easier to operate than digital equivalents. The three principals settings for any photograph are, shutter speed, aperture and ISO. We have Control dials for the first two so why not for ISO? One the front of the thumb grip perhaps?
  
• An Eyecup that doesn’t fall off: another one of my major gripes (that I know is an impossible request). For a camera that costs as much as the 5DMII, the crappy little plastic eyecup is truly awful. If you’ve never had reason to remove this it may have remained in place just fine. If you use an angle finder like me, you’ll know, sooner or later the eyecup it won’t grip anymore and will easily come off. Now I always travel with a spare.

You’ll notice I haven’t mentioned resolution in any of the above and that’s because I’ll take it as a given that resolution will be increased and I suspect, to around 24 mp or greater.  An increase in resolution is sure welcome, but 21 mp is pretty good for me, so it’s just not on my list. Also my last few items are mainly issues I have with the current body style and operation, most which I’ve mentioned before, and which I hold little prospect of ever being addressed by Canon.

Well, those are my wishes, now let me hear yours. Comments welcome…

When All Else Fails – The Gold-N-Blue Polarizer

Equipment & Techniques

As a amateur photographer and working man, achieving quality time for my hobby is more often than not quite difficult. For me, the main opportunity often turns out to be the family summer holiday. However, unless you’re off to sunnier climes and spectacular scenery overseas, here we have to put up with the unpredictability of the British climate. Many’s the time I’ve crawled out of bed at some ungodly hour, half asleep, and set off in the dark to some distant location only to be greeted with a sunrise that’s hidden behind a thick carpet of grey cloud. Welcome to the English summer! Once more, when I return, the rest of the family is just settling down to breakfast and I’m then expected to ferry them around and entertain them for the rest of the day and well into the evening. It makes for long tiring days, often without the reward of at least one good photograph.

But what to do when that sunrise doesn’t materialise? It’s disappointing to put it mildly, and after several days in a row it can be down right maddening. It’s easy just to give up, go back and may be even try and catch a little more sleep before the rabble awakes. But hey, us photographers have to make the most of things don’t we?

Well exactly that happened to me whilst up in Northumberland last week. For several mornings in a row I ventured out from our holiday cottage in Craster to the fabulous Dunstanburgh castle, only to be faced with dull lifeless skies. At least some mornings there was a bit of a breeze and then my Lee Big Stopper (10-stop ND) filter could be put to use. Then I remembered my little used, Singh-Ray Gold-N-Blue polariser.

Like most photographers, I’ve been through the coloured filter phase, and have sunset and tobacco grads and a whole host of other enhancing filters that reside within a CD wallet somewhere. But they seldom see the light of day and these days and seem considered almost bad form by some. I’m not knocking them though; they do have their place, but I just don’t seem to use them anymore. I’m certainly not adverse to adjusting my pictures in Photoshop or Lightroom however, and firmly believe that I want to produce a picture that is pleasing to me, not just a photographic representation of the scene at the time. I certainly don’t like over cooked images, if you know what I mean, but see nothing wrong with adding a bit more colour, vibrance and contrast.

During my ‘Cokin Filter phase’ I also acquired, at some not inconsiderable cost, a Singh-Ray Gold-N-Blue Polarizer, but initial experiments with it’s use seemed, to my eye, a tad unpleasing. It too remained at the bottom of my filter wallet.

Well, if there was ever a day for experimentation this was it. I was at a great location but with lifeless skies and poor light. Out came the Gold-N-Blue.

The Gold-N-Blue filter works like a normal polarizer excepts that it enhances blues or yellows as it’s rotated, and both to a lesser degree somewhere in-between. I found it possible to add some yellow to the skies and blues to the water which I though helped the scene tremendously. The gold certainly brought out the barnacles, shells and seaweed on the rocks, and added interest to the sky. The blue extreme enhanced the blue in the seas and when dull adds magenta.

Lastly I added the Lee Big Stopper 10-stop ND filter and took some long exposures  of some rocks. Both these are exposed for 100 seconds with the above picture taken at the blue end of the polarizer at F/1,1 and the one below at the gold end at F/11. Both have enhanced vibrancy, clarity and contrast within Lightroom 3.

I hope you’ll agree, both are far more interesting than dull grey skies. The Gold-N-Blue polarizer should now remain a regular in my Camera bag.

Lowepro Pro Trekker 400 AW Backpack Review

Equipment Review

I must confess to being bit of a camera bag junky. I’ve tried loads of bags and have so far failed in my quest to find THE prefect camera backpack. I guess the perfect backpack simply doesn’t exist as there is always something that could be improved, and personal tastes vary too. However, the Lowepro Pro Trekker 400 AW for me, comes seriously close.
By far the majority of my previous purchases have been bags by Lowepro as I've found them particularly well constructed, but I have also sampled bags from Kata, Crumpler and Tamrac.  I’ve read countless reviews of bags too numerous to mention, and have scoured the net for useful user feedback, so with this particular purchase I took my time and did my research before I was ready to part with my hard earned cash.
The Lowepro Pro Trekker series comprises the 300, 400 and the 600 with numeric designation being related to the maximum size lens the bag can accommodate whilst attached to a camera body, thus you can fit a camera with a 400mm lens within the Pro Trekker 400 AW. It will fit the larger bodies too or those with  battery grips attached.

Snow, Fog an Accident and a New Lens

Latest Picture

It’s funny how things come about. Last week I was out with a group of photographers down on the rocks at Robin Hoods Bay on the Yorkshire coast. It was an awful day, extremely blustery, with rain, hail sleet and snow. Unfortunately for me, whilst briefly turning to get something out of my camera bag a huge gust of wind blew my tripod over and my Canon 5D Mark-II complete with my 24-105 f/4.0 lens ended up face down in a rock pool. Luckily neither got fully submerged as the kit was covered with an Op/tech rain sleeve (highly recommended at 2 for just over a fiver!) which probably saved my bacon. I retrieved the equipment in a flash (well as fast as this old frame can move in a blizzard) and dried everything off the best I could. Thank god for weather sealing on the 5D MII, I think my old 5D M-I would have been done-for had the same happened to that.

The camera seem to work OK but the LCD didn’t come back on for a few minutes. A small amount of water seemed to have got in past the rubber stop on the Extension System terminal on the base of the camera, but after cleaning and drying this out all seemed OK. However, I had been about to attach my Hitech filter holder adapter ring to the lens, which I continued to try to do but it wouldn’t attach. On close inspection I saw the outer threaded rim of the lens was cracked in two places. Dam, that was a blow (or words to that effect!).

Alright accidents happen, I’m insured, I can get it repaired I thought. But I’ve booked a holiday at Staithes in a couple of weeks, and have a photo trip down to Dorset at the end of the month. This is my work-horse lens...what I’m going do if it’s not repaired on time?

Well I guess you know the answer, yep I bought a new lens. I'd always fancied trying one of those cheap Canon EF 50mm f/1.8 primes that get pretty good reviews. They used to be really really cheap but now have crept up to eighty odd quid. Still worth as punt perhaps at that price. However, after several hours reading many online reviews I decided that forking out an extra couple of hundred for the EF 50mm f/1.4 was perhaps a better investment and Amazon duly got some more of my money.

The lens arrived yesterday just after I’d taken the kids to school, complete with UV filter and lens hood (all extras of course). It had snowed the night before and was really foggy, but I had to go out and try it. Above is one of my first efforts (converted to monochrome), rather minimalist I know, but I thought the tree, especially with the broken branch made a good subject against an almost totally white background. As for sharpness, it seems ok, a little too early to tell, but not bad. Contrast, well not the best subject to tell with either. But you can be sure I’ll let you know how this lens performs real soon.
