Not long ago I bought a Jobo CPA-2 processor and have been developing 4x5 sheets in the 2500 series drum. Recently, I have had problems with undeveloped "blotc hes", especially near the edges of the film. Some of these can be quite large. Does anybody know what these are from? I suspect they may be from air bubbles. I am using sufficient chemistry .
