I have been seeing this sort of thing, light struck areas at the bottom of the frame, intermittently on some of my negatives for some time now. Checking through my notes, I find that it is not correlated with any camera, film stock, bulk loaded or factory cassettes, developing tank, etc. The only constant is that if it appears on any frame of a roll of negatives it appears on a number of the other frames, at least to some extent. The above is a frame from a bulk loaded 24-exposure roll of HP5 Plus in a Snap-Cap cassette, shot with a Nikon F6 and developed with Rodinal (1+50). The last roll of film I shot with that camera, the last roll of film I loaded in that cassette, and the last time I followed that developing regimen showed no such issues.

Many believe that only this temperature will produce good results and go to elaborate lengths using things like water baths, immersion heaters, refrigerators, ice cubes, etc. in an attempt to keep all of their chemicals and wash water at exactly that temperature for the entire process.
