Colour film developed as black and white, by mistake…
I shot a roll of what I thought was Tmax 400 through my Kiev medium format camera today. I had marked the back Tmax when in fact it was C41 colour (the rolls look the same) Portra 160.
I then developed it as I would Tmax and only noticed it was colour film once I took it out and hung it to dry. Here is a scan from the screw up. The original had a strange tint to it so I converted it to black and white.
I am amazed that anything even showed up.
