Pushing slide vs. negative

[Tim Gray]

It seems to me that slide film is often recommended for pushing +1-2 stops, while I see it a lot less for color negative film. Sometimes I even see pushed slide film recommended over color negative film (pushed or not). I'm specifically thinking of Kodak E200 and Fuji 400x. Why is this?

I can't answer your question directly, and will leave it to someone else. But what I can tell you is that in my own limited experience pushing film, color print film generally needs a lot of added exposure. For example, I generally rate Fuji 1600 at EI 1000 and process normally. I've pushed it one stop several times, and generally have rated it from EI 1600 to 2000 for a one-stop push. For a two-stop push, I would rate it at 3200 or maybe higher, but not much.

When I pushed Ektachrome 400x, I rated it at EI 1600 and pushed 3 stops. But I could have used even more exposure in some cases, as the slides came out dark and thin.

When I pushed Kodachrome 200, I rated it at EI 800 and pushed it 3 stops. It came out about right, but my scanner still had a tough time with it.

By the way, your color tri-x shots are very cool. Was it hard to do?

Oh thanks. No not really, just need the three color filters and take three exposures. I used Photoshop's auto align function to help with the registration, but it probably wouldn't be all that difficult in Photoshop by hand.

I would go with E200. It pushes like a charm to 800. I have gotten okay results pushed to 1600. I am more of a slide guy, but I there is no doubt in my mind that Portra 800 would do well too.

Thanks for the suggestion, however I was more curious as to why slide pushes better than negative. Or if that is even a true statement.

I've never done a comparison. But I have to wonder whether you hear more about pushing slide film vs C41 simply because fast slide film (ie ISO 800, 1600, etc) simply doesn't exist. In other words, maybe people push slide film more out of necessity rather than anything else.

Where are the examples? I would love to see them.

The one in the kitchen of the candles has a Kodachrome look to it.

I tried that once. It was very cool. After all, it's the basis of all color materials.

I have been making Tri chromes for a while:

Here is one:

As to why it is better to push slide than negs, I think some labs won't push negs as either their machines are roller transport with set time/temp or they do't like to do it because the base/mask goes a funny colour making it harder to print, ditto the three colour channels diverge at different rates but that happens with E-6 also
