Yes there is both push and pull processing. push processing is to over develop by develop the film longer to compensate for underexposure. Pull processing is the reverse, develop for shorter time to compensate for overexposure. I did it back in the late 70's because the fastest slide film was only 200 so I need to push for high speed. Today I would never want push or pull as both have negative effect on the quality. If I need high ISO I shoot digital. I now only use 160 film as the fastest.
