info - Cross Processing
Hello.
I 'd like to know a little more about cross processing for c41 films in E6 chemicals. Which kind of negative film could be more suitable than another one for this process? Do I have to correct EV for cross developing? How can a cross-processed film can come out? Are these films much different from "normal" slides? If yes, in which terms? Many thanks in advance -- il Clod! |

Which kind of negative film could be more suitable than another one for this process? - Almost any standard film, but the combination between over/underexposure, lab and film each gives a different result on color and contrast Do I have to correct EV for cross developing? - try and miss - there is no "correct" exposure How can a cross-processed film can come out? - different colors, strong blues, green cast - almost endless variations, as mentioned above Are these films much different from "normal" slides? - no, but color and contrast is... If yes, in which terms? - color casts and changed, often higher contrasts. It is also possible to do this the other way around - processing E& films i C41 - and another range of effects. Many thanks in advance -- il Clod! |

[cut] Experiment. Ciao! Well, I think I don't have clear ideas about this, but that's a start :-) If you (all) know about some links or books where I can find more infos, that would be a great hint Bye -- il Clod! --------------- "I don't mind eating if it's possible to make a martini sandwich." -- Hawkeye Pierce |

Hello. I 'd like to know a little more about cross processing for c41 films in E6 chemicals. Which kind of negative film could be more suitable than another one for this process? Hard to tell, since the results vary quite a bit. Also, there are few examples published. Do I have to correct EV for cross developing? I have done a bit of this cross processing, though across a limited range of films. In general, I have found that two stops extra exposure is needed. An example from Portra 400VC in E-6, was that I needed to set the camera to ISO 100, and the lab processed the film as ISO 400 E-6 film. How can a cross-processed film can come out? Usually a bit more contrasty, and sometimes a bit more blue. Often some odd false colour palettes will appear in the final image. The images might look a little normal, but something will make them seem alien. Are these films much different from "normal" slides? The thickness seems to be different, and there is a colour cast from the film base. The colour cast can be from orange to greenish in colour, and will be noticeable in clear areas. If yes, in which terms? Generally muted colours sometimes, and an overall colour cast are the most apparent. However, not all films respond the same to cross processing. Many thanks in advance --* il Clod! The best I can suggest is to experiment with one film. Shoot the first roll and bracket many different types of shots up to three stops extra exposure (try 1/2 stop changes). Take notes, and have that first roll developed, but not cut, nor mounted. Try using a warm up, or light orange filter, and see what effects it gives. Experiment. Ciao! Gordon Moat Alliance Graphique Studio http://www.allgstudio.com |

I 'd like to know a little more about cross processing for c41 films in E6 chemicals. Cross-processing is my favourite technique for producing eye-catching images. There's lots of inspiration as well -- my current favourite photographer is called Annabel Williams, and she uses the technique a lot, even in commercial portraiture work to great effect. Her particular cross-processing mix-and match is Provia 400 in colour negative chemistry, although the only advice anyone can give you with regard to this effect is experiment lots and lots. I've put some very hastilly cropped and compressed images online which are colour negative film - e6 cross-processed - which is my preferred 'direction' to cross process in. Because you're going from a low-contrast film, it gives more muted effects than slidefilm-e6, but still brings some wacky results.. Sadly, they were taken about six years ago, so I don't have data for them. High key lighting works well : http://www.cyccom.com/andy/temp/cp-1.jpg http://www.cyccom.com/andy/temp/cp-2.jpg (the second is quite overexposed - I'll come onto that later) You tend to get an insane colour cast : http://www.cyccom.com/andy/temp/cp-3.jpg ... although every film reacts entirely differently. Hint: what else were you planning to do with your near-to-date film stocks ? :-) Which kind of negative film could be more suitable than another one for this process? This is down to preference -- you might like your effect to be more subtle, or you might want a pronounced contrast-shift and colour cast. The fun is in the experimenting though. Do I have to correct EV for cross developing? There isn't really a 'correct' EV, but you will need to bracket your exposure widely to give you a range of images to choose from. If you overexpose your film two stops and develop for the regular speed of the film, you'll get 'medium' results in most cases, but if you have a good idea, or are practicing, try overexposing more for high key subjects, and underexposing to see what that does to colour. Slide film - C41 will NOT give you the same exposure lattitude you would expect from colour reversal film. How can a cross-processed film can come out? Ooh, I've just found some scans from negatives which have been started life on slide film (i.e. colour transparancy - c41) which is the 'direction' you were asking about .. these were took in 1996, but I distinctly remember using Kodak film for this shoot - Elitechrome? http://www.cyccom.com/andy/temp/cp-4.jpg http://www.cyccom.com/andy/temp/cp-5.jpg http://www.cyccom.com/andy/temp/cp-6.jpg Notice that with this combination, the cast is less pronounced and contrast is stronger. I like the colour the sky went in cp-6.jpg Are these films much different from "normal" slides? If yes, in which terms? With any luck this wont have answered your questions, it'll have given you even more to think about -- the only way you'll answer the questions is to have a play. This Summer I might make it a project to try out cross-processing techniques and document the results. Please have a play and show us your results ! -- regards, Andy Davidson |
