So, for quite a while I have been scanning slide film and black and white. With good results. However, lately I decided to try C41 at home with a CineStill automatic heater. And so I loaded some color negative, shot and went developing. And scanning. But what, there was brown striping in homogenous areas. So, I thought ’bromide drag’ or uneven development, and decided to do vigourous agitation the next time. And so it went, and what, again some discoloured stripes. Now I thought it must be some stain or residue on the film. So I decided to mix new stabilizer and do washing between the steps. But what, there was striping again. Now I googled uneven development and someone suggested scanner banding. So I flipped the film upside down and scanned an compared. The striping had switched side on the image ! So it was the damned scanner and not my development that was wrong. I read that the blue channel is noisy and weak in RGB sensors and affects color negative badly because the orange masking. And certainly there was fluctuation in the blue channel, and it was much weaker than the other two. Now I start to understand why Rollei tried to introduce Digibase color negative film without orange mask. I double checked with my flatbed, and there was much less or none ’staining’ but I certainly don’t want the unsharpness and lousy resolution of a flatbed. Likewise I won’t buy a drum scanner or a Hasselblad. Sad feelings…, but at least I have decent negatives.
