[Frameworks] cross processing Plus X reversal

[John Woods]

I usually over expose one stop when cross processing Tri-X or Plus-X. But I 
always hand process my own when doing this and thus have more control over 
developing. I would recommend you talk to the lab doing the cross processing if 
they have any advice.

The reason I overexpose is because of the nature of reversal film. In reversal 
film because you are bleaching away the negative and a second developing creates 
the positive, so you actually want the initial image (the negative) to be thin 
so that in the second development you will get a nice dense image. Consequently 
when cross processing it makes sense to overexpose so you get a dense negative. 
However, having said that I shot many early rolls in an automatic camera that 
were cross processed with fine results. Its really a bit of opinion & experience 
in what you want to get out of a film when cross processing. 


I've got some recently shot Plus-X film that I accidently underexposed by a 
stop. I had intended to get a lab to develop it normally but I think I will do 
it myself now probably as a negative after some snip tests. I've never 
deliberately underexposed Plus-X before so it will be interesting to see what I 
get, but I'm sure I will have something to work with.

Does anyone on the list have any experience is processing Plus X reversal as 
negative. I need to know what is the optimum asa to be filming at and what is a 
good lab that will do this. Thanx
