AVOIDING THE BURN
AS A PHOTOGRAPHER, YOU CAN EMPATHIZE WITH THAT FAMOUS MOTH AND HIS FATAL FASCINATION with a candle flame….especially if you’ve ever flirted too close to the edge of a blowout with window light. You want to gobble up as much of that golden illumination as possible without singeing your image with a complete white-hot loss of detail. Too much of a good thing and all that.
However, a window glowing with light is one of the most irresistible of candies for a shooter, and you can fill up a notebook with attempted end-arounds and tricks to harvest it without getting burned. Here’s one cheap and easy way:
In this first attempt to capture the early morning shadows and scattered rays in my office at 1/100 sec., f/5.6, ISO 100, you’ll see that the window is a little too hot, and that nearly everything ahead of the window is rendered into a silhouette. And that’s a shame, since the picture, to me, should be not only about the window light, but also its role in partially lighting a dark room. I don’t want to make an HDR here, since that will completely over-detail the stuff in the dark and look un-natural. All I really need is a hint of room light, as if a small extra bit of detail has been illuminated by the window, but just that….a small bit.
In the second attempt, I have actually halved the shutter speed to 1/200 to underexpose the window, but have also used my on-camera flash with a bounce card to ricochet a little light off the ceiling. I am almost too far away for the flash to be of any real strength, but that’s exactly what I’m looking for: I want just a trace of it to trail down the bookshelf, giving me some really mild color and allowing a few book titles to be readable. The bounce plus the distance has weakened the flash to the point that it plausibly looks as if the illumination is a result of the window light. And since I’ve underexposed the window, even the wee bit of flash hasn’t blown out the slat detail from the blinds.
Overall, this is a cheap and easy fix, happens in-camera, and doesn’t call attention to itself as a technique. There are two kinds of light: the light that is natural and the light that can be made to appear natural. If you can make the two work smoothly together, you can fly close to the flame while avoiding the burn.
