I am a newcomer with a Tachihara 4x5, 3 schneider lenses(sorry, read too much Ken Rockwell), film holders, loupe, tripod, manfrotto tripod and 410 head, box of txp320, bottle of hc110, combitank, a d2, a pentax analog spotmeter that was calibrated by Mr. Ritter and many of the other essentials. Wanting to do film speed test then development test. Is the featureless target for the film speed test light, dark, white? I've read it a hundred times and can't seem to get my simple mind around it. I'm getting bogged down in the details and yet to take a picture.
