Can most labs push super16 negatives by 1/2 a stop?

It depends on the lab, but I know most do - at least in 35mm.

Hardly seems worth it, since that's only like a 3 to 4 point correction on the printer lights, within a margin of error for exposing, and probably would not give you EXACTLY a half-stop more density.

If you're pushing in order to shoot in lower light, it seems like you could find another half-stop somewhere.

Hi,

Many labs will tell you they can push 1/2 stop. In reality it may get processed as normal or push 1 stop.

Since I often rate a one stop push 2/3 stop faster, a half stop push would be ~ 1/3 stop gain (not doin' the logs here sorry :)

IOW yes sort of exactly !

Not really a routine service offering. Changing to a different "push" or "pull" processing condition usually means clearing the processing machine of film by threading in leader, changing the machine speed, then running a control strip to verify the sensitometry of the process. This all takes time away from production, so there is an extra "setup" charge, and a limited number of conditions offered.

With minus half a stop exposure, the latitude of the Kodak VISION2 color negative films will usually produce a very usable image with a normal process. Push-1 if you want to increase the contrast a bit, along with a bit more graininess. Remember, a push process does not really increase true speed as much as you hope, it just increases the overall density and contrast of the negative.
