>>3891045for c41 most labs will do "push processing" without changing times because it tends to cause color shifts so if you shoot various speeds on the same roll it's simply the same as underexposure anyway. which is to say it doesn't matter.
picrel is ultramax shot at 800 and processed at 400. i didn't even bother to tell the lab.
e6 doesn't have this problem because you push the b&w step only.
