Triple light!

vincent_portrait-2

A friend of mine asked me to take some portraits out near Gróto, here in Iceland. I had an idea for a lighting setup right away, but I would need to borrow a third light for it. Luckily a friend of mine has the same setup as I do (vivitar 285hv with skyports) so I asked him if I could borrow it.

Here is the setup diagram (this is the same 3D view, twice. Top version is from the front, bottom version is from above):


Settings:
3 Vivitar 285hv
2 rim lights at 1/4 power,
at telephoto zoom setting,
through 1/2 CTBlue gels,
1 main light at 1/16 power,
at telephoto zoom setting,
through 1/4 CTOrange gel,
through Lumiquest softbox II,
rim light stands were at 1.5 meters height,
light was slightly behind subject, and 3 meters to the sides of the subject, just outside of the frame,
aimed a bit up to feather downward,
main light on boom arm held by assistant,
1 meter above face and in the front.

I wanted an extremely wide view, with rim light on either side. I knew this would make the subject pop, but I didn't want to take it too extreme. I started at 1/16 power on the rim lights, but it didn't show up quite enough, so I popped them to 1/4 (I've only hacked one of them, so I only have 1/8 on a single flash, out of the box, 285hvs don't have 1/8 power). The blue is to unify with the coldish color of the background.

The main was a bit harder, as it needed to be held. Without an assistant, this would have been near impossible. There would have been a light stand in the scene, and it was far too windy for a large C-stand. I put the lumiquest softbox so the light wouldn't be too harsh, and a 1/4 CTOrange gel. Not only is warmer light more flattering for portraits, but it would contrast well with the coldness of the rest of the scene, showing exactly where the focus point is. I left this main flash at 1/16 as I knew that since it was much closer, it would be strong enough. This was also my hacked flash, so I could have gone as low as 1/1024 if I needed to. In hindsight, I wish I would have tried a shot or two at 1/32 or 1/64.

For post processing on the above shot, I made a custom mask for the clouds and adjusted the curves to get a bit more funky sky color and definition.

This was a lot of fun having access to a third flash, and I might have to add a third flash to my kit soon. There are several other photos from this shoot, but they will be in tomorrow's post.

More natural light

summer_vacation-37

While on vacation, I infrequently bothered with my flash equipment. I was always on the look out for nice lighting for a portrait session. The above photo was one such time. The setting sun to the right provided a nice orange colored fill light on the right side of his face, and the soft cloudy sky provided a blueish rim light on the left side of his face. I just had to figure out a good rotation of the subject, and then my placement in relation, to best take advantage of the lighting. I normally hold up my hand, and rotate around it till I see the lighting hitting my hand in the way I would want it to hit a face. (the light, not my hand)

In this case I thought the setting sunlight was a more flattering shade, so I used it as the fill, and rotated Agust until it hit a good portion of his face. I then moved from left to right, to get the angle of him that I wanted. It was fast and painless, but a very nice soft light, with good color contrast.

summer_vacation-33

Here is another example of a naturally occurring flattering portrait light. This is a mausoleum in Hollywood Cemetery (Richmond, Virginia). There is a door behind the camera, of the same size and shape of the far door you can see behind me in the photo. This let's in a nice directional, soft light, but the darkness of the interior kills the rest of the light. This way you get lit surfaces facing the window, and dark shadows on surfaces facing away. You can see the shadow from the mausoleum walls on the right side of my face. In addition to the lighting, the dark walls with bright window provide a framing element to bring the eye to the subject's face. Good environmental portraiture will have interesting elements surrounding the subject, but they won't steal focus from the main attraction.

Look for directional natural light sources for flattering portraits. Look for framing elements. Look for contrasting colors in your light sources. When you search for good natural light, it can give ideas for cooking your own lighting setups later.

Movie poster lighting dissection



I saw this poster at the movie theatre, and (much to my friend's chagrin) stopped for a few minutes to dissect the lighting. I think it's quite a powerful image. First, it has great composition: the black line of the horizon is on a line of thirds, his head is on an intersection of the line of thirds, and the lighting from the far right corner travels up his leg and creates a leading line right to the face.

This is my attempt at replicating how I think the lighting was done:


Three lights:
Blue light is the bright rim you see on his face. It is quite hot compared to the front fill light, which is why I think there are two lights for his face. One hot one, behind, for the bright rim, and one less hot (bright) for the fill of the face. It looks like they used bare bulbs, with no light modifiers, so show off the texture and specularity of his skin. It would be unflattering for a woman, but for a weathered demon-man, harsh lighting works well.
The white light is the fill light on the front. You can tell that it's also angled off to the left because of how heavy the shadow from his pecs are.
The red light is kind of a combo of the left two. It's providing rim light, but also a slight bit of fill (on his gun hand, for instance). It needs to be less bright so that it doesn't compete with the main lighting on the important areas (his face and rock hand).

This is a great look, and one I'd like to try to replicate sometime. It seems to use just 3 lights, all bare (though the right light might have some slight modifier on it) which could be emulated with 3 small strobes. Whenever you see a lighting setup you enjoy, try to dissect it.

Sunset with small softbox

agust_sunset

Settings:
1 Vivitar 285hv
set to 1/16 power,
at telephoto zoom setting,
through Lumiquest softbox II,
light stand was at 2 meters height,
light was even with camera, and just outside frame right,
aimed directly at subject's face.

Sunset photos are easy and produce very pleasing results. This portrait, while not all that exciting, demonstrates the use of the small softbox when moved in close. I feel from this example that the small softbox is a bit too harsh still to produce a good main light, if the ambient is too dark (like in this example) However I like the falloff it produces. If I were to do this shot again, I'd most likely use my silver umbrella, and block off the bottom portion to get the same falloff. However as a softer than barebulb fill, or in a lighting situation where there is more ambient, this light-mod will work well.

There was a much hotter specular on his forehead and cheeks, but I reduced it in photoshop by "select by color" using white, and reducing the feathering till I only had the highlights. Then I used levels to reduce the brightness, giving it a softer look. I opened up the shadows with the fill light slider in lightroom. Before these two adjustments, the lighting on the face was more severe, and less flattering.

Jean portraits

jean_portrait-4

Whenever I can get someone to sit for a portrait session, I jump at the chance. Fresh faces can be inspirational. Two things came together for this particular session. First, I had been bicycling by this exact spot several nights in a row on my way out, at this very hour. The light and reflections of the lake were so beautiful, I knew it would make a great backdrop. Secondly, I'd just purchased a small softbox that would sit on my flash without blowing over, a real concern here in Iceland when running with no assistant to hold the flashes. I wanted to see what I could do with this new light mod. You can see it in this post, the lumiquest softbox II.

The first shot we met near the city hall, which has this nice ledge that pokes out into the lake. I knew it would give me reflections, and the round windows in the background would provide framing elements.

jean_portrait-2

Settings:
1 Vivitar 285hv
set to 1/16 power,
at telephoto zoom setting,
through 1/2 CTOrange gel,
through Lumiquest softbox II,
light stand was at 1.5 meters height,
light was even with subject, and 3 meters to the right of the subject, just outside of the frame,
aimed a bit up to feather downward.

The softbox managed to soften the light more than a bare flash, but not as much as I'd like from this distance. The nose shadow is still quite hard, but in this setting it works well enough. If I use this setting again, I would position a 2nd flash to subject left, with a slight blue gel (as the natural light was already that color) to pop him from the background. (in this photo I faked it in post)

Then we moved to the main location that I'd observed the previous nights. We walked along the edge until I felt the background elements worked best compositionally. I wanted the church and city lights to show in the right of the frame, but I wanted a dark spot for his head to fit. I used my thumb as a stand in for his head as I walked, till I found an area that worked. I still had the softbox on the stand, so I just needed to adjust height and position. Bringing the ambient up to match the flash was difficult. I was already shooting at iso 400, but I had to really drag the shutter for this to work. (dragging the shutter means using a longer exposure than would normally yield a sharp photo, but the short, intense duration of the flash, 1/4000 of a second or so, ensures that the subject is sharp despite the short shutter, sometimes the background blurs a bit in this situation though). The 1/2 cut CTOrange gel provided a nice contrast against the blue background.

Settings:
1 Vivitar 285hv
set to 1/16 power,
at telephoto zoom setting,
through 1/2 CTOrange gel,
through Lumiquest softbox II,
light stand was at 2.5 meters height,
light was even with camera, and 1 meters to the right of the subject, just outside of the frame,
aimed a bit up ( about a meter over his head) to feather downward.

Post production for these was quite fun, as it was my first time using Lightroom 2's new adjustment brush. Tomorrow's post will demonstrate some of my post processing techniques.

Light modifications

This post is going to explain the various light modifications that I use in my portrait photography. This will serve to illustrate what mods I mention in posts, as well as to show how you can modify a small studio strobe.

First off, bare bones flash with skyport wireless trigger. This is the foundation, where everything builds off of. The skyport triggers the flash wirelessly, the front of the flash can accept gels (there is a 1/2 CTOrange gel in it in this photo), and the head can zoom from wide, normal, and telephoto.

285hv_bare

Next, is a "bare bulb" emulation mod. This is just a white frosted container that scatters the light in all directions, like a real bare light bulb would do. Normally the flash is directional, but with this mod, it works like an omni-directional light, sending light off in all 360 degrees. Useful for lighting small places, hiding inside a real lamp, car interiors, etc.

285hv_barebulb

Now I've attached a Dave Honl 1/8" gridspot. The flash head is zoomed out to telephoto as well. This mod throws the light in a very tight, very narrow beam. Useful for isolating the light to a single area.

285hv_gridspot

This is a Lumiquest Softbox II. Normally the flash "size" is exactly the dimensions of the flash head. This gives a very hard light that is not very flattering for a front light. By increasing the light's apparent size, you get a softer look. This small softbox doesn't blow over in the wind like my umbrella does, and allows for a great feathering affect that's harder to achieve with an umbrella. I'll demonstrate the feathering affect in my next portrait post. I am in the process of building a snoot for this softbox, which will give me a soft, isolated light.

285hv_small_softbox

This one brings the juice. It's the 285hv cranked to full power, with a small slave flash velcroed on top. The 285hv has a GN of 120, and this slave flash a GN of 80. This gives me a GN of 144 (thanks for the math Jasphoto) brighter than the high end canon and nikon flashes. The flash only has 2 settings, high and low, but I leave it on high, and set it to slave, and it's triggered when the main flash it's on top of goes off. The same velcro that I attach the soft box to, holds my skyport slave on the side of the flash.

285hv_with_slave

This is that same setup, aimed into a silver umbrella. Right now the handle is choked up on, but if I extend the umbrella all the way, this really packs a punch of soft light. Great for groups, or if the light has to be out of the frame on a wide angle shot.

285hv_with_slave_into_silver

Now I've attached a white nylon sheet. This is just white rip stop nylon from a fabric store, with grommets for the umbrella tines to go through. It has a slit to the middle for the umbrella shaft, and then had fray-check (a sort of fabric glue) to keep the slit from fraying. This setup is incredibly soft, and extremely powerful. With the slave flash velcroed to the 285hv, it can really pump out the light. The reason I like this better than a white shoot-through umbrella, is that this provides a 43" flat white soft light, rather than a rounded one that curves away from the subject. It makes a difference in the wrap around light.

285hv_with_slave_into_silver_with_diffuser

In the future I'm planning to build a small card for the honl grid to further restrict the light to a tiny area, a snoot for the softbox, and a snoot for the white nylon'ed silver umbrella. Being able to "not light" is almost as important as being able to light. Control is the artist's tool.

Beach portraits

beach_portraits-5

This past few weeks I've been in the US, specifically to the Outer Banks in North Carolina. I took my camera and lighting gear with me, and managed not to take any scenery photos, but lots of portraits. I loved how the fading sun gave me lots of interesting texture in the clouds, and we had a wrap around porch on the 3rd floor, which gave me a vantage point to get plenty of sky and a bit of beach houses.

I wanted to do some full body portraits, showing the beach setting, the cloudy sky, and provide a bit of falloff to the light so that everything wasn't lit evenly. It was also just a chance to experiment more with lighting and using my new flash equipment (Honl honeycomb grid).

Settings:
2 Vivitar 285hv
Main set to full power,
at telephoto zoom setting (to keep the light only on the subject)
Rim set to 1/4 power,
through 1/2 CTBlue gel,
through Dave-Honl 1/8" grid-spot,
Full zoom setting
Main light stand was at 2.5 meters height, rim was set on the balcony rail (about 1.2 meters high)
Main light was even with camera to the left of the subject, just outside of the frame
Rim was even with subject, 2 meters to the right of subject,
Rim light was aimed at his head, main light aimed directly at the subject.

Click through this setup shot to see notes over the flash heads.

beach_portraits-6

I started originally with a sunset red gel over the flash, but it proved to be too strong, so I removed it. In hindsight, I wish I'd put on a 1/4 CTOrange gel on the main flash to warm everything a bit. Notice how in the setup shot, you can see how using the telephoto setting keeps the light only on the subject and feathers nicely off into the wooden balcony? I like the setting, but next time I'll aim up a bit more so that it feathers his body a bit. On all the subjects, the lower body received too much flash and removed focus from the face. Aiming the flash up a bit would give me more natural feathering of the light.

One thing I really liked was the Honl Honeycomb grid. I'm not a fanatic about keeping my strobe clean from velcro, so I forewent the speed strap, and just attached two velcro strips to my flash head. This cut down on the cost of the grid. The grid allows me to keep the light in a very tight, laser beam like area. In these portraits it was used to keep the 1/4 powered blue fill on just the face. Click through to the larger version to see it in detail.

beach_portraits-7

This shoot however has convinced me that I need a small softbox for when I want to soften the light just a bit, or for times when an umbrella would blow over for sure (a real problem in Iceland where it's always windy).

Full beach portrait set
A few more examples:

thug_sarah peetree

My next post will show my new DIY umbrella mod. I'm building a white diffuser for my silver bounce umbrella. It's inspired by the 60" softliter that I purchased. The softliter is far too heavy and bulky for my taste, so it sits back in the states in my dad's lighting kit. The best part about it was the flat white surface. It's the best of both a silver and white umbrella.

Also, a request. Will anyone who knows of a university that teaches all in English, has a 3d art and photography degree, and is not located in the US, or the UK, please contact me via email?
