Could anybody advise what went wrong with the sky here? It looks for me like bad development.
The film was developed by Toronto Image Works lab. A reputable place, but I had a number of misfortunes with them recently.
awesome bubbles.
Luckily it sounds like it's not a fatal flaw in processing, if it is just photoflo (which it probably is, not much else makes froth with that big of bubbles)
It may be that you put two films in the tank and only chemicals enough for one (I've done it - luckily not a job!). The chemicals would slosh around enough to develop the film when you agitate but when the tank's sat still, the top film sits amid bubbles.
