    I agree with the previous comments and would like to add that you may have taken photographs under different lighting conditions on the same roll and had an incorrect exposure for the first or early frames which the machine printer used to make their settings and the rest were off as a result. There is a simple test you can do to determine the iso for your equipment but it would be best to develop and print yourself or find a technician who will work with you to do it.

    i think the ultimate reality is that i should start pulling together stuff for a dark room, i have a place to put one that just needs to be cleaned out.

    i also think my negs look pretty good, i was a little surprised they didn't print very well.

    i'm going to take a roll using different guidelines for exposure that my internal meter and have them printed to see if they turn out. i'll develop them the same and have them printed at the same place to try to minimize the variables. i think that'll tell me once and for all if my meter sucks or is out of calibration. if they turn out the same i'll know i need to adjust my development or have them printed a different way.

    at least i'm having fun

    thanks for all your help.

    Not really much of a surprise. Many moos ago, around the turn of the century, an "Infallible Exposure Calculator" (not sure of the precise name - something like that) was manufactured, using much the same information, stamped/ engraved into a metal disk with rotating scales. If memory serves me, it utliized "Waterhouse Stops" ...

    While the results from these systems can be, and at times IS, fairly accurate, any system using subjective judgement is prone to error, and I don't exclude the usual "eflective/ assuming 18% gray" meter, either.

    My only advice would be to try to learn as much as possible about the "18% gray" bit, and try to make intelligent guesses in the future.

    Come to think of it, my Olympus OM-4 has an internal meter that is switchable between 18%, 95%, and 5%.
