I scanned in my second set of negatives and noticed there was an issue. I ran into brown stains (which from my research implied I didn't have it in the fixer long enough as this is only the second use of that fixer so it shouldn't be exhausted) and some "dots" on some of the images, especially at the edges. I managed to rescue many of them in LR4 with cropping (I also did some exposure adjustments.)

Here is a picture directly from the camera that shows this. I should also add I'm not sure if the film went on the spool 100% correctly. Were the dot's also caused by lack of fixing time? I was using ilford fixer and I'm sure I had it in for at least 30 sec. I should also add that it was probably 75F degrees in the house so the chemistry was probably warmer than usual. Thoughts??
