I am planning to embark on a minor photographic project, and I would like to tab other's experience of pulling possibilities of reversal films, particularly provia 100 and 400 and velvia 50. I am interested in enhancing their zonal range, and concrete suggestions about how much developing times can be reduced, with or without colour corection filter, would be extremely helpful for me, as I not only have to catch up with the characteristics of these films, but am facing labs here in Lahore I am not familiar with, and I would like to be able to give them as concrete instructions as possible.
The data sheets say Provia 400 can be pulled up to 1/2 stop (EI 280), Provia 100 and Velvia also 1/2 stop. I wonder whether more is possible, and what happens then?
