Hmm… I didn't sense any degree of snarkiness. What I did sense was a serious attempt to help you determine what caused your problem. Looking at the photo you offered, I could definitely see a "been there, done that" problem which I have also encountered. I tried using Photoshop to correct the underexposure and really kicked up the grain. I was using Fomapan 100. It is a somewhat crappy film with a horrid curling problem (I'm using Fomapan 120), developed in HC-110 dilution B. To be honest, I thought the photo was pretty cool, the grain gave it some character.
Not from you or most other people (see my other reply). I do appreciate the many helpful responses I received. And thanks for the feedback on the photo.
