I started shooting film a couple of months ago with a Pentax SPII without a working light meter and seemed to be getting decent exposures based on the scans of the negatives I was getting(done by the lab). I've recently started doing some black and white myself and did my first contact sheet the other day having just printed a select couple of frames previously. I noticed that the exposures seem to be all over the place with some of the contact print images being very dark and a couple very light. However on the negatives there still seems to be plenty (probably?) of detail.
I assume the lab must have been correcting the scans? Are the differences on the contact sheet just because my guesses at EV are wrong (I think so)? Could it be that I still have all the information due to the film's exposure latitude? What benefit would buying a light meter have if the exposures still have all the information? Would it just allow easier printing as I wouldn't need to do test strips for every frame?
