Assignment 2: In the Can in Five, Pictures
Took me long enough to get to this, so here it goes.
Simple shot really. I was asked to take some photos of a couple of fresh roses. I decided that since this was going to be a single light shot, I’d go for a black background reminiscent of many macro shots, but obviously this isn’t a macro shot. If I had a second light I would probably have thrown some light on the background to add some interest and depth.
First the diagram:

As you can see from the setup, this wasn’t all that complicated of a shoot, only a single shoe mount flash was used. I set some black foam core against the wall in the background so I didn’t have all the clutter that’s really there. And I used a large (30″x60″) sheet of white foam core to act as a reflector filling in the shadow side of the rose.

This was the first shot, I hadn’t thought about my umbrella, in fact my first though was to use my tracing paper scrim clamped to a tripod. I think I had the flash at 1/64th power for this, and yes, I pretty much nailed the exposure on the first shot. You really do get good at this the more you practice.

Realizing that the hard light just didn’t do it with the subject I switched to my trusty compact umbrella. Here I had widened the zoom on the flash from 105mm in the first shot to 24mm to fill the umbrella evenly. I knew I’d loose some light with the wider zoom and the umbrella so I pushed the flash up two stops to 1/16 figuring that would be sufficient. Alas I was wrong there.

Dialing in, realizing that the last shot was way under, I intuitively bumped the flash power upto 1/2. No really, I didn’t even think about what I was doing at the time, I was very much on auto pilot. That pretty much nailed the exposure.
From this point forward I played with some different compositions but I already had the necessary shot in the bag, and that was sufficient for this project.
