pushing of slide films, exposure compensation


I enjoy shooting negatives due to its tremendous latitude. pushing, pulling, going over, under as per the light or colour of the object; I enjoy myself. In fact all this while I've been so happy with the results that I've used it for most of my assignments, only to scan the negatives upon processing. Make no mistake, I'm happy doing it like this. Now then, I want to experiment with slide film. How much of a push can it take? 2 stops at the most? say 100 ISO pushed to 400 ISO, would this cause too much grain? More than negative?

  from what I've seen, one stop.
but if anybody's done it to two, or if you want to, I'm not saying you can't.
Just that I would choose trying to get what I want at a one stop push than to go to two.

Michael H. Cothran   Not only will your grain increase, but so will the contrast. Pushing past one stop is risky business at best. For optimum results, shoot the entire roll at your chosen EI, then be sure to take the film to a qualified photo lab that can custom process 1 or 2 stop pushing. Of course, this special processing will cost more. Your best bet is always to use 400 speed film rather than pushing 100.

  I've pushed 100 ASA E-6 slide film to 200 with great results.
If you're going to 400,..Michael's advice to buy 400 speed film makes better sense than "pushing" the limits of a slower film.

Girish Menon   I like what I get out of pushing a film (negative) by two stops. the grains and contrast are to my liking. I even push 800 ISO films to 3200 ISO, mind you; those shots are made at f1.8 , 1/60 despite 3200 ISO only because I don't like using a flash. I think one stop sounds correct when shooting slides, lets see how it goes. I will be better off using 100 ISO film pushed to 200 ISO rather than using 200 ISO straight :) Thanks;

  Grain and color shift....be careful.
No more than one stop my friend.

  Here's a few examples of one-stop pushes with 100 speed slide film:

  How much one can push (or pull) a film (negative or transparency), if it should be done at all, depends on the film. They all react to it differently, and some are "better" than others for pushing and pulling. Read the manufacturer's data sheets on each of the films you're considering using. It will have information and recommendations about pushing and pulling the film.

While some of what's been posted are generally true for many E-6's, there are exceptions. One finds these in the data sheets and some trials using the recommendations can see what the effects of push/pull are. Agfa Scala 200X, a B/W transparency, is one of the "friendliest" to being pushed and pulled. It is designed to be pulled by a stop, or pushed up to three stops, giving it a five stop working range. Pulling opens up its latitude by nearly a stop at the highlights end but doesn't do much, if anything, for granularity reduction. Pushing shrinks its latitude some (but from what I've seen not severely), and it does increase graininess.

  pull out a digital camera and push the button and forget the lab (they'll be in a mesuem some day)

  museum, but then digital will also be. By then we will just hook up an ethernet cable to are brainport and download. And I think I'll wear my polarized glasses
