Hello everyone, I was hoping for a bit of help. I recently purchased a Canon TX and I just put my first roll of film through it (Ilford HP5 400). While many of the pictures came out well, there were a few in which a black strip appeared on the right side of the image. These were taken in the sun, at either smaller apertures (8ish and above) or quick shutter speeds (1/250 or 1/500). I've put some images for reference. Are these film problems, or camera problems? And if so, what should I do? As far as I can remember, the first and third photos were at 1/500, and the second was at 1/250.
