Strange texture of film

[humberland]

Once upon a time I got myself a 35mm roll of Svema CND 64 color negative film. Film which expired in March 1993. Recently shot and developed in native chemistry. What happend to the film base or emulsion (?). I developed tons of expired films but never seen such strange texture before.

Do you guys have any idea what went wrong, or it's just fault of film itself being too old?

Looks like reticulation

Here's what google says

Reticulation occurs when film is exposed to extreme variations in processing temperature. The negative image appears "crinkled" or cracked throughout the surface and is damaged beyond repair. This error usually occurs when heated developer is inadvertently placed into the developing tank immediately after mixing. If the stop bath is too warm, reticulation can occur to a lesser degree. As the degree of reticulation is reduced (by using cooler solutions), the cracked surface is no longer a problem, but film grain size often becomes increased. The solution to this problem is to carefully monitor the temperature of all solutions used in the development process. On rare occasions, reticulation can lead to production of prints with some degree of artistic merit, but most negatives damaged in this manner yield unsatisfactory prints.

Dunno but it looks cool, doesn't it? Maybe wrong storage of this particular roll?

Thank you for quick answer! It sounds reasonable. I'll make more tests with other rolls. Set of chemistry used in this process was also expired (expiration date 09/1981). But colors turned out nice (nice for Svema color film of course).

I am happy that I got anything from this roll 😀 It was factory boxed and sealed but I don't know what were the conditions of storing.
