Lighting tools and camera synergies.

Chartier.

I was looking across the littered studio this morning and noticing that I'm not really a camera junkie as much as I'm a lighting junkie. As I looked through the little piles of lighting fixtures I starting into the reductive mindset that tries to eliminate clutter by pushing me to make choices and get rid of everything I don't need.

The two piles most in conflict, at the moment, are the new fluorescents over the older LED panels. They both cover the same shooting situations. They both provide continuous lighting for video and good lighting for just about everything on my bucket list. But here's what you have to know about bigger continuous lights (the ones that plug into the walls).....they require more overall stuff in your lighting package when you leave home.

If you use flash you can put each flash on one stand, then apply a softbox or an umbrella as a light modifier directly to the light fixture without having to use a second stand. When I set up my big fluorescent light or LED light there's no easy way to attach a softbox or umbrella and, honestly, I wouldn't want to if I could because it would take away too much light and drive my exposures towards lower shutter speeds or noisier ISOs.

So when you want to modify your big LED panel, or your even bigger fluorescent panel, you generally use a separate diffuser on a frame which requires a second light stand and an attachment mechanism. You gain some lighting control since you can carry a range of diffusers and nets, etc. but you definitely add to your packing craziness.  Four flashes generally means four light stands while four fluorescents generally means seven or eight light stands (you might not need two stands for the background light...) to do the same basic lighting set up. More if you want to bring along black flags and modifiers for the modifiers.

My recent excursion into the world of location video/photography required eight light stands, a background stand system and two tripods (one for the video set-up and a second for the still work). It also required collapsible frames for the 4x4 foot diffusion scrims along with clamps to hold them.

While it would be nice to light exclusively with one type of light the real world makes this difficult. If I worked only in the studio or other interior locations where sunlight was something we looked forward to seeing on our way to lunch I'd be happy enough with my new fluorescents.
But there are still a lot of assignments that require me to go on locations and balance man made light with bright sun and, for still photography, that's still the territory big, portable flashes like the 1100 watt second Elinchrom Ranger RX flashes work best in. 

Then there are those more complex interior exterior locations like the CEO standing in front of a vast wall of floor to ceiling windows. She'll need to be balance with the sun drenched scene behind her and might require a few supplementary lights behind her, which is efficiently handled by three or four electronic flash mono lights.

So, even though we are now providing hybrid video/still content solutions we still need some variety in our lighting equipment to handle all the situations we seem to get into.

I'm sure some of you have leapt forward to the logical question: "Weren't you all jazzed about LEDs last year? Why now the fluorescents? Have LEDs failed?"

Hardly. But there's an analogy that's something like cellphones. The big LEDs I currently have---the ones big enough to kick out effective levels of light----are very much G1. (First Generation Technology). They require me to jump through a few hoops to make them work well. Mostly they need to be intelligently filtered. And the newest fluorescents with the latest tubes are better, color-wise, and a couple stops brighter than my three to five year old LEDs.

I looked hard and long when I started really moving into motion at replacing my current inventory with the latest panels from people like Lowell. Their Prime Light LED panels boast a 91 CRI and they are markedly brighter than my existing panels, so better light and more of it. But here's the rub, they are about $1800 each and every lighting set up I do seems to require at least three lights. That meant spending $5400 to replace my original investment of about $1200. Would they be demonstrably better? Yes. Could I make a better investment to get the same results? Yes. 

When I visited the Museum of Art in Boston, Greg Heins showed me the Alzo fluorescent lights that his photography and video department use for video programming and interview. Very good light, requiring very little correction and about a third the cost of premium LEDs for the same three light set up. Most of the advantage for the Alzo lights come from a new generation of fluorescent tubes so I started to research all the options and came up with the Fotodiox version. I give up dimming controls but gain a price advantage.

I've used the flo's on six or seven mixed video and photography assignments in the last month and they are working out well. My one concern (and this is where LEDs absolutely rule) is hauling all of those oh-so-very-breakable glass light tubes around. I think breakage is inevitable with the tubes and hardly possible with the LEDs.

There's a second area in which LEDs have all other light sources beaten, hands down. And that's using them with batteries. My smaller LEDs, the color changing Fotodiox 312AS panels use two standard, camcorder batteries for power and can light at full power for around two continuous hours. No other light source is anywhere near as efficient. Which means I have to keep my case full of these lights for those kinds of run and gun shoots where plugging in and accessory light stands are just not in the cards.

And that brings me to the stack of "hot lights" I have sitting over in the other corner. Why the heck am I keeping these primordial light fixtures around?  Well.......first of all they keep me warm in the winter when I use them (just kidding, not a good reason...). But really, I have several Lowell Totalights, a Lowell DP light and three of the Lowell VIP lights that fold up for cartage. I use them for the times when  wall of LEDs or Fluorescents isn't enough for a special application.
Sometimes you just want raw power and, though they are hardly efficient, for their size and relatively minor investmentm, they can really push a lot of photons through big diffusers. They're my go to lights when I need to shoot continuous and I need both low, noise free ISOs combined with medium to high apertures.

So far I'm counting a number of systems here. Two kinds of LEDs. Fluorescents, High Powered-battery powered Electronic Flash, Electronic Flash mono lights and a pile of hot lights (tungsten).
But we really don't stop there. We have to consider the portable speedlights. We have a couple of the big Sony flashes because they work well on and off camera and can be used wirelessly. Then there's also a motley collection of manual-mostly speed lights along with radio triggers, that are left over from the Strobist/Minimalist lighting days.

I use the speed lights for candid shots at events and though it seems like this market is in an off cycle right now I'm sure it will swing around again when I least expected. For their size the on and off camera flashes are a potent lighting tool. Without (real) modeling lights and fast recycling they won't take the place of studio flashes and with their 100-200 watt second flash power they won't replace the large Elinchrom Rangers in sunlight but they sure are handy to have when following an executive around a trade show or whipping up good light for an impromptu portrait.

So, of all these things how can I best consolidate in order to pacify that part of my brain that's rebelling against the clutter and demanding some rationalizing of the vast VSL lighting inventory? I've decided that the first generation LED panels must go.

I'm going to sell them locally for some price that makes no sense. Live in or around Austin and want to play with 500 bulb panels or 1000 bulb panels? I'm asking $100 per smaller panel and $150 each for the two bigger panels. I won't ship them because they are too bulky and heavy to make it sensible. I also hate to pack stuff. If you want them you can e-mail me and we'll meet up.
Take them all and we'll price the lot accordingly.   Edit: the LEDs have been sold. Thanks.

Another day at the photo office. Working with two cameras. Including the new Sony a58.


A quick summation of last week's hybrid job.

We set up a temporary portrait and interview studio in a big conference/mixed use room. I brought along one of my favorite color management tools, a Lastolite gray/white target. In this room I used the big Sony a99. One click white balance worked for both the stills and the video. I like setting the color correction once in shooting instead of pasting it in post. I lit with two fluorescents and one LED light. And I brought my own stool for the subject's to sit on. The more stuff I can control the fewer problems I seem to have. I went for five hours with one lens. It was the 85mm 1.5 Cine lens from Rokinon.


Using the big Rokinon at wide apertures, in close is what the Sony a99 was built for. The lens is totally manual so I rely on focus peaking to ensure sharp results where I want them. 


I brought the Lastolite target out onto the assembly floor and balanced both the cameras for the existing light. Made it easier to shoot because I only had to focus on composition and focus, not on color balance. I tend to use manual exposure and all of these shots were taken in a landscape format with the camera locked down on a Manfrotto video tripod with a fluid head.


By moving quickly with one camera on a tripod and one camera over my shoulder we were able to move through the space quickly. After every still shot I ran about ten seconds of video and then moved on. We got fifty or sixty set ups during the course of a long day.


I had the client carry a small Fotodiox LED panel around with us but it didn't get much use. I liked the bright way the area was lit and, with the preset color balance the images were easy to work with in post.




My one and only gripe about the 85mm 1.5 lens is the close focusing distance. It's 39 inches. I'm spoiled, the Sony 85mm 2.8 focuses much closer. But then again it doesn't do quite as well at f2...



I unabashedly like the new a58 camera. It may be because I always use it with the 16-50mm f2.8 DT lens. I like the range of focal lengths and I love the high sharpness of the lens. The image above was made with that combo. With all the present generation of digital cameras there is a freedom in being able to comp and shoot a scene as a still photograph and then spin a dial and start shooting the same thing on video. Double threat. Most the work I did on this job with the a58 is available light, handheld and at ISOs of 800 and 1600. The OLED viewfinder is great and the built in IS works well for me. No matter how I handled the camera the metering was spot on.


I decided to live on the edge for this shoot. I realized that there's no way to shoot raw video files on the a58 so I needed to get any video I shot just right in the camera. Just like shooting jpegs. Since they were equally important to the client I decided to go ahead and shoot jpeg as well. I might as well take advantage of the extra care I was using to get things right for video...

The a58, like the a57 before it is small and light and highly usable. The new sensor is sharp and detailed and has as little noise as the a57 did but delivers a much better user experience both in the EVF and the actual sound of the shutter. I can report no focus problems in over 600 shots under regular working conditions.

While this shouldn't be construed as a review I would like to say that the tools are so suggestive to the way I take images. While the a99 was on a tripod, using a longer MF lens the a58 was always handheld and used with a fast wide to short tele zoom. With the smaller camera I found myself moving around the edges of subjects and quickly trying new angles while the locked in camera was used in a more straightforward way.  

All cameras are good these days. I don't care about brands but I know that for my paying work I'll never willingly go back to a camera that doesn't have an EVF as an integral part of the design. Now, after selling off other systems, every camera I have except the Sony a850 is equipped with an EVF. And when I pick up the 850 I have to slow down and think more about operation. That means I think less about the image. I like the real time feedback of the newer finders. They make the feedback loop much more effective.

That's it. Get yout mom an a58. Ask her if you can borrow it. Happy Mother's Day.

The End.
