B&W negative looks normal when projected onto mirror.

I had a test roll of Ilford 100 B&W film developed but didn’t have prints made. I took one of my favorite shots and projected it onto a mirror with a flashlight to see what it looked like and found that at a certain distance, the image looked like a normal B&W photo. Does anybody know why this happened?

At some angles and against some backgrounds - I think you need a dark background and light illuminating the negative - you wind up seeing a combination of reflected light off the negative, and transmitted visibility of the background, that makes the image look like a positive.

It seems to work better with thin negatives, so while it is cool, it also can be a sign of underexposure.

Thank you! I asked on another forum and they were less than helpful.

That makes sense though. I hope it isn’t underexposed, it’s of a 50’s Porsche and it probably my best composition yet.

I thought my settings were correct but we will see. I didn’t have prints made because I bought a scanner to scan my film but it hasn’t come in yet.

I hold them up toward my black wall in the darkroom with an inspection light on them. It's easier to assess what the thin shadow areas of the neg are doing than the highlights. This trick works especially well with pyro stained negs.

For years i purposely did what you have done accidentally so that I could easily see a positive image prior to deciding what to print. It made me lazy about making proof sheets, but saved a lot of time and paper. I frequently go back to those negatives and print them in one or more alternative processes. Nice fast printing times.

...kind of like an ambrotype or tintype...

Thank you all! I think it turned out ok. 201816201816
