I've been doing some film developer combo testing. Anybody have some clever way to do this? Usually I set up a set of targets (black, grey, white cards) in the sun and take a series of test images. Right now, all we have here is clouds and mud. Sometimes I image a step wedge. This has its moments, too, but doesn't really tell you what an image will look like. Lately, I have been imaging inside under lights, but I don't really have a lot of indoor space. I can calibrate out the tungsten shift.

What I'd like is some means to use an enlarger with a coldlight. Seems possible. I guess I could put a step wedge in the enlarger and a shutter on the enlarger, but I am worried about the light leakage and to some degree the color of the light, but I could plug up the holes and calibrate the color shift. It doesn't really tell me the quality.

It just may be that there is no one good answer, but I thought I'd ask what others are doing --- you are a clever bunch.
