The negs look really dark for the most part in the image area, although the rebate area is clear (other than frame numbers and film info). I didn't make any adjustments for exposure, although I got similar results with shots that had no snow or especially bright features (including ones I took in/ of shaded areas). I didn't try using a separate light meter, as I've not had problems with this camera's metering before (I even put in a fresh battery yesterday).

I believe Ultra 100 is, in fact, rebranded Fomapan.

The developer is in a dark brown bottle that's a little less than half full.
