Light Festival

light_festival2-1

One year ago, a company called Vegalume came to Reykjavik with their light costumes for the light parade. I was asked by the company to photograph the parade. They were quite happy with the results, and so when their next large gig came up, they asked me to be the photographer. In Germany. This is probably my largest professional gig yet, where they covered my flights to and from Germany, as well as my photographers fee. This is an example where your reputation is extremely valuable. There are a ton of photographers in Germany already, who actually speak German (unlike me) and most likely at least a few who can do low light photography. However they did not know any off the bat, so a time-tested photographer they have worked with before, and that they know can deliver the results they want, is worth the extra expense of flights. This was a very expensive and one-time event, in front of the Dom cathedral in Cologne (the largest gothic church in northern Europe), and a repeat was not going to happen. They had to be sure the shots came out right the first time.

The event itself was too quick and large to use my flash equipment, so this is all available light. The costumes themselves provided most of the light, but there are street lights and lamp posts littered around the square. This required my camera's fullest light gathering abilities. I was using the 35mm f/1.4 lens, ISO 1600, and 1/60 of a second (to be sure to avoid hand shake, and to freeze the movements of the actors as much as possible). The noise levels are acceptable, and the illumination is sufficient. Post processing involved boosting the light areas, and then increasing the deep shadows, as noise is always most evident in the dark areas. By lowering the deep shadows, the worst noise gets damped down into black. On my favorite images ( including the top image) I make a new layer, use noise ninja to do aggressive noise removal, then use a mask to reveal it only where the noise is offensive visually. This results in clean areas of low detail, but leaves detail in the more busy areas.

Toward the end, one of the actresses was given these flaming wings, and she performed alone. The fire provided a lot of extra brightness, but she was moving much faster than the other dancers, so instead of decreasing ISO or aperture, I decreased the shutter speed, to be sure I froze her actions.

With any less light gathering capability to my gear, I would not have been able to achieve this level of illumination. With an f/2.8 lens, I would have been boosting my ISO 1600 shots to ISO 4500 or so to get a similar illumination level, which would have far more noise and less color accuracy and less dynamic range. (color accuracy and dynamic range decrease as ISO increases, as well as the obvious sharpness and detail of the image). Ideally I would have used the 24mm 1.4 lens, to get more of the cathedral in the background showing, but the rental agencies in Germany were already closed when I arrived the day of the shoot, and I do not own that lens. It's on my lust-list however.

Belly Dancers part 3

bellydancers_part2-13

Settings: Ambient was 3 stops below neutral grey. One flash into a 60cm umbrella above and to the right, at 2 stops above ambient.


One of the dancers from the original shoot asked me to come out to Akranes (a smaller city about an hour north of Reykjavik) and photograph her dance team, as well as some individuals of herself. I used save, even lighting for the group shots, but once I could focus just on her, I could play with more contrasty lighting. I used only my 60cm umbrella, as she had great skin that would work well with it.

bellydancers_part2-14

Settings: Ambient was 3 stops below neutral grey. One flash into a 60cm umbrella above and to the right, at 2 stops above ambient. There is also a bare flash on the ground behind her, pointed straight up, at 3 stops above ambient. You can see the rim slightly on the bottom of her forearms.


It was great to have someone so eager to perform in front of the camera, and the costume made it even better. Once I had my lighting ratio setup, I was able to ask for all types of poses, and as long as I stayed in the same general angle to the flash, I was getting good lighting with contrasty shadows. On this fullbody shot, I had placed a bare flash on the ground behind her aiming up. I got a little bit of rim light separation, but I should have zoomed it wider so it hit more of her veil to really light it up.

bellydancers_part2-15

Settings: Ambient was exposed at neutral grey.

After getting some good lit photos. I wanted to try some warm candle lit photos. I asked her to lay down on a pillow, and I moved several candles in close to get as much light as possible. I cranked my camera to maximum light gathering mode (ISO 1600, f/1.8, and 1/80) The shutter speed was so low that I had to brace my elbows on the ground to avoid camera shake on the 85mm lens. Normally I try to use 1/160 of a second with this lens. Even with this much sensitivity, I had to boost the brightness about .6 in lightroom, making this about ISO 2500) The soft candlight really added a nice mood. However her makeup had an odd reaction to the candle light and slightly discolored her face to a green color. I made a quick brush adjustment with a color overlay of a light magenta, which popped it back to the color of the rest of her skin, and much more natural.

The rest of the set.

Belly Dancers part 2

bellydancers-10

Settings: Ambient is 4 stops below neutral grey. One flash into 110cm umbrella, 2 stops above neutral grey, on the right, and one flash into 61cm umbrella, at 1 stops above neutral grey, on the left. Both flashes were set to maximum height of about 2 meters, and angled at 45 degrees to the group.

These are from the same shoot as the last post. This dance group needed promotional shots for an upcoming show and asked me to help. Luckily they had a black seamless paper roll set into their ceiling, which made for a nice backdrop. Despite the sun streaming through the blinds, by using 1/250 and ISO 100, I was able to completely kill the ambient for some nice contrasty shadows. I asked the ladies to stand as far away from the background as possible, so that the shadows would be as unnoticeable as possible.

bellydancers-3

By putting the two lights at 45 degree angles, and at the maximum stand height, I could be sure that everyone would receive lighting, and there would not be too much shadowing to obscure details. This way I could focus on the ladies expressing themselves with the different dance poses, and not have to worry about them moving outside of the lighting area. I made sure to do the group shots first. It was the main reason for the shoot, so I wanted to make sure I had it in the bag, before people's energy wore off, or possible equipment failure.

bellydancers-1

Next I wanted to shoot individual portraits against the black seamless. The seamless was at a 45 degree angle to the camera and the subject. This ensured it went to full black, since less light was received by it. I also had a smoke machine outside frame left, which I turned on briefly before each shot, in order to add some interest to the floor level, rather than leave it plain.

bellydancers-4

Settings: Ambient is 4 stops below neutral grey. One flash into 61cm umbrella at 2 stops above neutral grey, to the left and at maximum stand height, facing down. Second flash is through gridspot, at 3 stops above neutral grey, to the right, aimed at just the head and shoulders.


This time, with only one subject, I had more freedom with lighting. I placed the 61cm umbrella to the left, aiming down. This would ensure the face and upper body was fully lit, but the lighting would fade out toward the floor, creating a natural focal point. I put my gridspot on the 2nd flash, and put it behind the subject, and to the right. I used the modeling light to ensure it was only hitting the head, and was gone by about the waist level. This gave me a bit of separation against the black background, ensuring the silhouette is clearly visible.

bellydancers-5

I wanted the dancers to look a bit regal, so I was crouched on the floor, to have a bit of an upwards facing angle. In post, I used a curves layer to make the smoke extremely punchy, and the background go extremely dark. I made a quick mask to keep it off the subject, and blurred it to fade smoothly. I used an inverted version of this mask, to warm the subject slightly. This color contrast also gives it a bit of pop between subject and background.

The shoot was quick and fun, and the girls had a great attitude about it. The fact there was no one there but myself, one other photographer who assisted me, helped keep them at ease, which enabled great posing and expressions. Too many extras might have introduced some self consciousness and stiffness. I was glad I did a bit of pre-visualization before heading out, as I was able to work much faster after getting there and setting up.

Sunlit blinds

bellydancers-8

A coworker of mine is involved in a Tribal Dance troop, and they needed photos for an upcoming show. She asked me to come over and do a few group, and individual shots.

When I got to the studio, the first thing I noticed was the awesome wooden blinds against the wall, and how the sunlight poured through them. It was quite convenient that it was one of the few sunny times in past days. I wanted the almost blown out look of the blinds, with a good bit of warmth to the light, and let the edges of the model be almost rim like in light quality, with a dark front to the face. I started at my lens maximum aperture (1.8) and the lowest shutter speed I could get away with handheld (1/100 to be safe). This still left the model a bit too dark, so I bumped ISO to 200, then 400 before I got a good overall light level.

bellydancers-9

Once I had good settings, I was free to let the models pose as they liked, as long as they stood in generally the same place, so as to have nice framing against the individual window frames. The light was very forgiving. This was the type of setup that would be almost impossible to emulate easily with my lighting setup. I would need to set up a bedsheet with strobes behind it, both at full power, and blinds directly in front of the bedsheet. Even then I would probably need to work at ISO 800 or 1600 even to get the light as bright. This is one of those cases where you're presented with a great existing light setup, and you should work with it as best you can.

If I were to experiment with anything else, it would be nice to put one of my flashes in my small 61cm umbrella, at lowest power (1/128) very close so it only hits the face. That might still be too bright, but would be fun to experiment with.

Work with what you've got

work_headshot-2

Settings: Window light to the right, tungsten ceiling lamp to the left.

A few days ago, one of our PR people asked me to take some photos of two employees at work. The problem is that she asked me the day that she needed them, and I hadn't brought any of my equipment to work, not even the camera. I asked around and a friend has his 400D plus 50mm 1.8, which is a perfectly usable camera and lens. (normally I prefer my 40D with the 85mm 1.8). Now I at least had a camera, but I needed some light.

Unfortunately, this time of year, Iceland only has a few hours of daylight, and it was nearing the end of these, plus it was overcast, so I had very little window light to work with. I scooted a couch right next to the window, and had a nice set to work with. The window light is on the right, and an interior tungsten is on the left. I angled the couch so it would be easy to get the window light onto both sides of the face if they turned towards it a bit. Had the couch been perfectly perpendicular, they would have had to rotate unnaturally far. The light was so dim, I was working at ISO 1600, f/1.8, and 1/80, pushing the limits of the camera sensor and lens.

work_headshot-1

Settings: Window light to the right, tungsten ceiling lamp to the left.

Once I had the two photos, it was off to processing. First, since ISO 1600 is quite noisy on the 400D, I reduced all chroma noise. I personally don't mind luminance noise in an image, I think it can have nice qualities to it, so I always leave it in, smoothing only on large solid colors that might be in the background. Next I needed to make a custom White Balance mask to suck out the yellowy green of the tungsten light on the left side of their faces. Then I did a quick highpass and smart sharpen to bring out a bit more micro contrast, and desaturated the shirts to make sure focus was on the face. This layer is masked to only contribute fully on the face, but fades out of the shirt and background.

Could I have done a lot nicer job with my full kit? Sure, but for a last minute corporate headshot, these work fine. Look for nice light and settings wherever you are.

Covered Garage

chantal_concrete-1

Settings: Ambient is 1 stop below neutral grey (other than the lighting fixture itself, which is 3 stops above) Main flash is into a 61cm umbrella at 1.5 stops above neutral grey. Secondary flash is aimed at the wall behind the circular opening, and is about .5 stops above neutral grey.

Several weeks ago, I passed a really interesting covered parking garage here in Reykjavik. I knew instantly that I wanted to use it as a backdrop for a photoshoot. The concrete and the long lights provided so much interest, and would contrast really well with a subject. In my mind, I wanted to do a full body portrait with a lot of the garage showing, but those shots didn't turn out so well. It was all the impromptu posings and backgrounds that worked best.

This was actually the final area/pose of the evening, and I think it worked best of all. I saw the circular opening, and knew I wanted to use it as a framing element. I asked her to stand inside it and put her arms out. The first several poses had good compositionl, but the way the light fell on her face wasn't very flattering. I took some time to examine the back of the screen, and asked her to move her head a bit forward so that more flash would reach it. This is one of those times where sticking to the shoot and asking for more, to ensure you get the right shot.




The post processing was actually quite involving, but because I felt there was so much potential to be had. Lately I've been shooting all my flashes ungelled, and color correcting in post, because I ended up doing that anyway to get the right colors, and this way I save time from having to bother with the gels. The first thing I did was to clone out the other circle in the top. It sucks because had I noticed it at the time, I could have reshot crouched just a bit lower, and it would have been gone. Once I had a clean plate, I used the liquify tool to slenderize her arms and waist a bit. The coat was extremely thick and killed her curves. Next I used the magic lasso tool to make a quick mask for the background, and used the cooling photo filter in photoshop. Then I made a custom white balance layer to subract the yucky green color from the flourescent lamp. I had to custom paint that mask onto her face and the concrete in order to remove it correctly. I liked the lamp a lot for what it adds to the composition, but the disgusting green had to go. Finally I used a slight warming filter on her skin to give it just a bit of warmth. Once the photo was where I wanted it, I used my typical high pass and smart sharpen combo to add some more micro contrast, but masked it away from everything in the face, other than the eyes, and edges of the nose. Female skin works well soft, so I left it that way, but eyes tend to look good with some sharpness.

chantal_concrete-2

Settings: Ambient is 2 stops below neutral grey. Main flash is into a 61cm umbrella at 1.5 stops above neutral grey.

This one is the result of a technique I've been trying lately with models. I asked her if there was any pose she was interested in trying, or thought would look good. She suggested having her hand by her mouth, and it worked out great. It took a few times of arranging the light till I was happy with how it fell, but I really like the final.



For the post on this image, I cooled the background, reduced the neon green of her ribbon, and tucked in the front of the jacket, and jacket sleeve. The shadow from her back made her look unnaturally wide, so I used an exposure layer to bring up the edge of the jacket and sleeve a bit, as if there was bounce light from the wall. I also fluffed up her hair a bit using the liquify tool.

chantal_concrete-4

Settings: Ambient is 1.5 stops below neutral grey. Main flash is into a 61cm umbrella at 1.5 stops above neutral grey to the right and in front of the subject, above head height. Secondary flash is zoomed to 105mm and through a gridspot, aimed at her head so that it only hits her hair. The secondary flash is about 2 stops above neutral grey.

This one is closest to my original mind's eye image of the shoot. I used a classic female pose, found on a 70's tutorial somewhere, and it helped, as originally she wasn't 100% sure of what pose to assume. We tried several, but I think this one was the most feminine and confident looking.




This one took the most time in post. Immediately I used liquify to remove the effects of the thick coat. During the shoot I asked if it was possible for her to angle her arm back in such a way that I could see a triangle of the wall between her elbow and the small of her back, as that's a very feminine aspect of the body. It was too constricting of a coat, and too uncomfortable of a position, so I added that part in photoshop. I cloned a bit of wall in to look like you're seeing through, then darkened the coat to make it look as if it really ended there.

Next I adjusted white balance on everything, neutralizing the green of the ceiling lights, and warming her face just a bit. I used a curves layer to add a lot more contrast to the background, and then used a technique from the Platon copy that I did. I used the mask of her figure to create an exposure layer, that darkens the image in a halo around her. It's only by about .4 stops, but it emphasizes her silhouette more and brings attention to her as the subject, allowing the background to fade away.

It was a great shoot, and many thanks to Chantal for being a lovely, willing model, and to Árnór who assisted.

Inspired by Platon

ivar_platon_copy-1

Settings: Ambient was at 3 stops below neutral grey. Main flash was into a 61cm silver umbrella, directly in front of the subject, and high above facing down at 45 degree angle. Main flash was at 2 stops above neutral grey.

I was looking at the photography of Platon Antoniou, better known as just Platon, today. I really like his use of single lights for portraits. I'm not sure what light modifier he uses, but it looks either smallish, or if it's larger, a bit further away than normal so that it might as well be smallish. I believe this because the shadows are soft, but there is still a lot of definition and rake to the lighting, which would only come from a beauty dish or smallish softbox. The nose is dark, and has a hard, yet fuzzy shadow, which also makes me believe it's a smaller light source.

This made me use my new 61cm umbrella instead of my normal 110cm umbrella. The larger one would have made much too soft of shadow edges, leaving no real black, and would have contaminated the rest of the room, filling the few shadows it did make.

I asked a friend over specifically to try to emulate Platon's lighting style. First, I placed the lighting source directly in front of him and above. You can tell from the nose shadow that the light is directly in front of his subjects, and the size of the shadow means it's above the head a bit. I fired some test shots till I had the brightness correct. I was working at 1/250 shutter to kill the ambient. I wanted my shadows dark, not contaminated by any lamplight from the apartment.

In order to get the light directly in front of him, I had to hold the camera in front of the light stand. I was essentially hugging the lightstand, in order to have it at the right distance. The subject was sitting about half a meter in front of the wall to prevent any shadows from showing. The first shots, the nose shadow was too little, and the face was too well lit, which kept it from showing the skull structure. I raised the light stand further to get some deeper shadows. I didn't want it so high that I lost the highlights on the eyes, or it would look dead.



Once I had several good photos, I loaded them up in Lightroom. I did some quick blemish removal, a little contrast, and desaturated a tad, then brought it into photoshop. First I changed the background from a dull yellow to a brighter blue-grey, and desaturated the tie a little. Then I brought in eyes from another photo that had better catch lights and less shadows. I liked how the cheekbones and overall head was in this shot best, but the eyes were a bit too dark. After that, I used high pass and smart sharpen to create a much higher contrast/sharper image, but masked it so that it only contributed to the face and tie, not the hair or sweater. Finally, I added the fake vignetting. If you look through Platon's portfolio, he must do this in post. Any of the full body portraits, the darkening follows the silhouette perfectly. It looks like he shoots on white seamless (a white background) and then adds this darkening in his post processing. I made a mask from the background, used the minimize filter to expand it 100 pixels, blurred it 100 pixels, then used that as a mask for an exposure layer, where I pulled it down 2.5 stops. I used a curves layer set to just this exposure layer to bring in some blue and green so it wasn't a completely linear fade.

Once back into lightroom, I added +5 to the blue White balance, and desaturated again a bit.
