Hi All,

Quick question, doing a film test for the first time.

I have exposed 6 sheets of hp5+ sheet with a stouffer 21 step wedge. Measured EV 4 on the base board. Developed the 1st sheet for 4 minutes(normal 12min published Xtol 1:1). Barely can see anything, got nervous that it is underexposed, so jumped to the development 11min as it is closest to normal fopr a sanity check, and about half are visible. Would I be right is assuming I am at least a stop underexposed and continuing will give me limited information with a densitometer? I figure that you should see most steps at normal..

Any help would be greatly appreciated.
