Lighting 102: Specular Background Assignment | Discussion

Results from two weeks ago, in which you were asked to shoot a portrait using an umbrella to both light your subject and create a specular highlight on the background, as in this example.

From the final edits, it is clear that this was a bit of a polarizing experience. You either got it or you didn't. It was either a natural extension of the experiments in the kitchen, or it was a maddening exercise in geometric futility.

The trick: Stay close to the umbrella and don't push that angle too much because everything is doubled. Also, maybe find your specular reflection first and then just stick your person in front of it. As always, click the pic for more info, or to leave props to the specific photographer.

The takeaway from this technique-based assignment is that one small light can be stretched to create a nuanced, three-dimensional portrait if you keep your eye out for a background with the right tone and surface quality.

Leading off above is a self-portrait by h_oudini, who used his armoire as a reflective surface. He took care of the crack between the two doors by applying a frontal lobotomy crop to himself. This is always a great solution for hiding an imperfection, whether the offending area be in the background or on top of your subject's head.

The surface quality of the background in this shot, courtesy Scott Campbell, is not as reflective as some of the others. This background results in a softer highlight being thrown back at you. It's more subtle and muted.

The expression is this photo is a nice bonus, too.

Since you can choose to include a specular highlight or not in these situations, you now have the ability to get two different tones out of any one dark, reflective background. If you are shooting in a fixed location (like a studio) just think of the range of background colors and tones you could have at your beck and call be keeping a collection of 4x6-foot pieces of cheap countertop laminate laying around. Seriously, this stuff is not that expensive.

Remember: After you nail the lighting technique, you still have to include some personality in the photo.

Which is exactly what itsjustanalias did. If you don't believe me, check out this composite from the shoot. If you want to keep a model happily sitting for you, it is hard to go wrong with pie.

Most of the entries were horizontals. But this technique lends itself well to verticals. And those can be done with a much smaller piece of real estate for the background.

This is a great trick to pull out when you need a potential cover in a pinch. And aigi is a cowboy killer (love those aliases, folks) came in tight and vertical for a more pensive version for his effort.

Once you get that background highlight lined up, move in. Hit some tight crops. Play around with the internal geometry of your shot.

Finally is this rather ingenious solution, which a few of you figured out. Can't find a good specular highlight background? Maybe you are looking in the wrong dimension.

No, not the Twilight Zone. It's just that maybe you were concentrating too much on vertical surfaces as backdrops. How many of you have a coffee table (or some other kind of table) which would have worked, turned on it's side?

That's what Danny Kino did. Nice thinkin' there, Danny.

Actually, one of the other shots pictured here used that same technique. Can you spot it?

So, them's the shots for the specular background portraits. See them all here, and the selects here. Group discussion is here.

As for the ones on this page: Nice, simple elegant, tonally rich photos, all. It's just a neat look, and I hope you feel comfy trotting it out the next time you want to do more with less.

But for now, better rest up, get some exercise and eat your Wheaties before next week. Because that is when we jump back into the lighting controls. Next is light balancing, maybe the most complex -- and most useful -- of all of the lighting controls.


NEXT: Balancing Flash at Twilight

Uhm...
That photo "that looks as if it was almost impossible to create without a second light source" - here's what the description clearly says:
"One flash in front and the other behind, pointed at the boards."

one + other = created with a second light source

As you said in this effort by AndrewJ.D resulted in a photo that looks as if it was almost impossible to create without a second light source. I thought so too. I clicked thru to set if there was a set-up photo, no luck but a description of the placement of the second light. I still think it's a great shot but not as an example for this assignment.

Great to see so many participating in these lighting assignments! I'm learning SO much. Thanks, David!

Oh, I would like to point out that Andrew J.D.'s photo is actually a two-light shot, not one. He says so in his description. :)

I think in the description of Andrew J.D's photo he says he did use a seond light source for the background.

Realy nice job with CSS, but I have problem with printing. Images are overlayed by text (text is written through image). Images are also located in different positions than in post at website. I'm using Firefox 2.0.0.6.
I'm also missing links between posts of Lighting 102 (and in menu on the right side) -- these were very useful.
Thank you. :)

my guess would be third pic. I've also thought of using my table, up-ended as a nice background. one day!

Hate to be a buzz kill, but Andrew JDs photo info on Flickr says he used 2 lights, not one... Great shot, but I'm just sayin...

I like Andrew's photo a lot, but in his flickr description he lists 2 flashes - one pointing at the background. So, I don't know that this is the technique being illustrated in his shot.

Thanks for the heads-up on the two-light version. Fixed. -DH

Awesome assignment. The posted results here are very nice, but I am surprised by the first image. Very nice light technically speaking, but it doesn't seem to capture a moment or expression, just the typical staring-at-the-camera self portrait.

We all have to take some degree of responsiblity for what goes on in Strobist. As publishers of our work, we need to make sure the tags reflect what the photo is about / for and not just rely on the comments.

My shot that David posted also has a two flash version which I took it as a "saftey" because my subject (Tara) needed a shot to publish. I even say it is a cheat in the caption. However, I did NOT tag this two flash shot as FINAL, so that it wouldn't appear in David's list of shots to go through.

I don't know if the photog of the other shot made proper use of tags or not. He may well have. I'm just sayin'.....

"The trick: Stay close to the umbrella and don't push that angle too much because everything is doubled."

That's not necessarily a problem right?

This advice assumes that the camera axis is almost perpendicular to the reflective background (which it doesn't have to be). I ended up not finding the time to work on the assignment until it was too late, but I managed to get an almost 45-degree angle on the lighting simply by tilting the background slightly so my specular reflection ended up in the right place.

Image here, and lighting diagram is here.

David, did you happen to keep a hit/miss count as you were reviewing the final edits? I'd be interested in your opinion of the "success" rate on this assignment.

You provided examples of "hits" but none of "misses" in your post. It is (of course) not fun having your work posted as a "miss" so it made sense. Would you consider taking a few of the types of "misses" and recreating them yourself? I found it useful to compare my final edit to the posted images and was able to find one and say "ok, mine's basically like that" but being able to also see the other side might help the "misses" self-identify and learn as well (for all I know, I might see a "miss" and realize mine wasn't really a match with the "hit" afterall.

Just a thought.

One question I have: Pretty much all the shots are a little too hot—as in they all seem to have at least one spot that's overexposed. The transition into the shadow areas look a little harsh as well. Is there a way to prevent this problem?
