Anyone know what would cause these lines? First time playing around with photos, so I doubt I have my settings right for the best quality. Ignore the very bottom, as my first attempt, I forgot to make it a negative. I was using a HR head, which has a 2.5mm focus length. I did end up with a lot of crud built up on the bottom side after this.
It’s a white tile with matte black paint
What’s odd is I ran the same files/settings, just not a negative, on wood and it came it fine.
