Pushing & Pulling Film:
you can read the full thread, or keep reading for my condensed version.

Pushing film involves deliberately underexposing your image, then asking your lab to push (over-develop) the film 1 or 2 stops to compensate. This results in higher contrast than you would get shooting and developing a film at its rated speed.

Pulling film involves deliberately overexposing your image, then asking your lab to pull (under-develop) the film 1 or 2 stops to compensate. This results in lower contrast than you would get shooting and developing a film at its rated speed.

Bear in mind that cross processing already increases contrast, so you may have to consider pulling the film to compensate. Here are a couple of real world examples:

• Its sunny outside, and what you are shooting is very high contrast. You shoot 200 ISO film as if it were 100 ISO. You then drop your film off and ask the lab to cross process it, and to pull 1 stop. This results in your pictures having more normal contrast while still leaving room for colour casts.
• You are shooting something indoors, and there is low contrast in your scene. You shoot your 400 ISO film as if it were 800 ISO. You subsequently drop your film off at the lab and ask them to cross process it, and to push 1 stop. This results in your pictures have higher contrast than they would have done normally.

Types of cross processing

• E6-C41: taking slide (colour reversal) film, and processing it in colour negative chemicals. This is the most common type of cross processing. It usually results in increased contrast with strong colour casts.
• C41-E6: taking colour negative film and developing in slide chemicals. This usually results in muted pastel colours with very little contrast. As a result you may want to ask your lab to push 2 or 3 stops to increase the contrast.
• E6/C41-B&W: taking colour reversal or negative film and processing as black and white. This results in a black and white negative. As colour film is usually more expensive than B&W, you may want to only use this technique if you are out shooting colour and decide you'd rather have B&W.

some cross processed images:
- The film used was Fujifilm Sensia 400/cross processed.

*First of all, cross processing may overexpose your image by about one stop. Therefore, you need to account for this when shooting. If you’re shooting 100 ISO film, just set your camera setting to 200 ISO. This will allow less light in, taking care of the overexposure. It’s best if you run a roll normally, with no adjustments, to determine if you even need to worry about this.

The first roll I did was processed pretty much on target, without any ISO adjustments.
