AdPro is great for "batch processing" Where you take entire imgages, resize them, recolor them, run a filter on them and resave them either as an image sequence.
Example of use:
Take 300 frames from lightwave rendered at 1024X768, reize them to 720X486, apply a noise filter, NTSC color filter, etc. then save the sequence of jpgs to a device like DPS par, that would compile that sequence of images into an animation that would playback in real time.
Why we needed to do this:
You have a master render of your scene at 102X768 for archiving and a "broadcast resolution" version suitable for D1/D2 Standard resolution playback.
These days Photoshop or After Effects replace BOTH ImageFX and ADPRO
Imagemaster for the Amiga was quite good as well.
