Hi Shel. Thanks for the link.
Lately I've been testing films myself, but I'm unhappy with my results.
I really would like to come up with a better procedure.
What I was doing was shooting a roll of tri-x that I sat on my b+w stove
with a 50 macro from about 2 feet. That way I could take a look at the
film can at my enlarger's full height to get an idea of how grain and
sharpness look. Plus I would do some shots of my backlit cat, maybe a
few other things.
The first problem I noticed is that if I shot during the day, the light
would change a bit. Even if the exposure was perfect, the quality of
light coming through the window could change the look of things (i.e.
cloudy versus sunny conditions).
I solved that by shooting at night under the flourescent bulbs.
Well, then I noticed that the tri-x wasn't a very good subject. You
also want to see how various colors are rendered, and since I basically
only had b+w and yellow, I wasn't getting that.
Also, I want to get some test shots of things that I normally shoot -
portraits and landscapes. Plus I want to see how things look using full
flash, fill flash, and natural light, how well the film holds detail
when underexposed, etc...
That's where I am now. Here's what I want:
- A typical test subject that shows a full range of tones. The subject
should have something that I can look at fully enlarged (the lettering
on the tri-x can was good for this). Shadows and highlights should have
some texture.
- One of the subjects should have a featureless light toned area. This
helps show grain.
- The lighting conditions, at least some of them, need to be easily
reproducible.
- I need some head shots. I want to see skin tones and texture.
- I want some shots with flash, some with natural light.
- I need to bracket exposures to see what EI works best, and see how
well it holds shadow detail when underexposed. At least I guess this is
the way to do that.
So, the next thing I'm going to do is write down the shots to take, then
start testing.
Anyone tried this?
