Hallo, ich möchte mal einen Diafilm (sensia, velvia) crossentwickeln... Kann mir jemand Tipps geben bzgl. der Belichtung? Muss ich über- oder unterbelichte...

Hello, I’d like to try cross-processing some transparency (Sensia, Velvia)... Can anyone give me some tips on exposure? Should I overexpose or suffer from underexposure? Many thanks and best regards, Andreas

I once had some Elite Chrome X processed (i.e. developed using the C-41 process). Once with an overexposure of 2 stops, which produced relatively ‘normal’ negatives (!), and once at the specified ISO (400), which resulted in extreme contrast and very, very rich colours. For “experiments”, using the specified ISO is therefore more interesting, but even with significant overexposure, the effects aren’t lost – they just become less pronounced. Simon

I haven’t tested this myself yet, but from what I’ve read, the general rule seems to be: always apply overexposure to Kodak films by one, or better still two, stops (and develop them at the standard speed), whereas Fujis apparently don’t need any correction. There’s a website with lots of sample images where pretty much the same subject has been photographed using lots of different films. The differences in the results are sometimes quite drastic, even with films that only differ in terms of ISO (Provia 100 vs. 400 etc.). Let’s see if I can find the link again... rocknroll Nils. edit: here it is: http://www.webmonkey.com//99/23/index3a_page4.html?tw=design -- otherwise, you’ll of course find plenty of threads on the subject ‘over there’.

If you know of a specialist laboratory (not a flat one...) that does this sort of thing, ask if they have a sample book. Best regards Martin

Hello, When it comes to cross-development, I can’t recommend Agfachrome RSX highly enough. The advantage is that this film’s neutral colour reproduction is largely preserved even during cross-development; it’s just that the contrast increases significantly. It is advisable to perform overexposure on these films by 0.5 to 1 stop to keep the contrast in check; however, the density of the negatives will naturally continue to increase, which is why enlargements can only be carried out with extremely long exposure times. Furthermore, you must be prepared for the fact that strong cyan filtering is necessary for colour-neutral enlargements of cross-processed Agfas, unless a colour cast is to be retained in the enlargement.
