Yesterday I noticed that a roll of Fuji Superia 400 had been shot with the ASA set at 800. I have a decent photo lab in town who will work with me on development times for pushing, but I've never underexposed anything this much before. Does anyone have any experience pushing this stuff that far? That is what I get for changing a roll in the dark, and having to set my ASA.
That is not much of a push. The film should look just fine in the end.
I would just tell them to add about 20 percent to their normal time. It is not exact, but it need not be exact to work.
The exception would be if you shot contrasty light/compositions (i.e. in bright sun with plenty of healthy shadows). Then I might just develop the film normally to keep from increasing the contrast even more.
Thanks. Not realising that I had the ASA set wrong I shot some of the frames -2 because of the light situation. It would have been spot on for 400. According to my notes that is about 1/3 of the roll. I'm wondering if that much underexposure will make a difference. The shots I really need are those at -2. I've not had a lot of experience with Fuji films. I do know that they seem to lean a lot more green than Kodak. At least this stuff does.
-1 or -2 isn't that bad really. It can be processed normally or with a push. A push will change the contrast and highlights. What sort of light were you shooting in? Were there highlights? If so, they may block up. If the light was fairly flat then a push may increase the contrast in a helpful way.
