What happened with this development?

[Photopathe]

I just got this defect on the image after developing. I used Xtol 1+1. The thing is that other films from the same batch of Xtol (same method) came out perfect. Gives me the impression that it's related to development but can it be the film ? Otherwise for me it's difficult to explain. And if it's the film, does one know what can be the source of the problem. It's not old film and it's from a good brand (Rollei).

Usually this is due to an interaction between the backing paper on 120 film and the emulsion. The problem is often exacerbated by moisture and heat. Especially storage conditions and time before the film is processed, but after the roll has been taken from its foil wrapper are factors to consider.

It's not old film and it's from a good brand (Rollei).

Years ago I had this exact problem with Rollei Retro 80S. Not that it matters - it's a long time ago.

What format is this? 120 ? If so, looks a lot like mottling from the backing paper.

I agree with the others as to what it is. I also don't rate Rollei in the "good brands" in terms of quality control... those are Ilford, Fuji, and Kodak. And even with them, you can occasionally get problems like this.

That being said, I think the images are still quite good, especially the first one, which I would definitely still want to use/print.

This is on Aviphot 200, which is the same stuff as 3 films Rollei sells. I found that when I used a red filter, the problem got very intense, and when I didn't, it was barely noticable. Not sure why. Maybe an exposure difference.

Could be reticulation...
