Scratching is exactly what I did the last time. With a knife, I wrote a terrible 8. ..
My Color film is developed by my local shop, and they cant push C-41, just pull so I just shoot it at 200.
I think I will start taking notes on my Iphone on important shots. But
One of the things I like is to develop a roll and not knowing what will come out, but perhaps it is worth it in the end to know some of the settings and when/where the shot was taken.
