I am a novice so please be patient. Over the past 15 years or so I have been using a simple filter that I created in Filter Factory to do some analysis on aerial photographs. I am way behind on updates (currently using Photoshop CS (version 8)). I want to upgrade and am using a trial of CS5. After talking with customer support I've found there is no way to use this filter in CS5 and Filter Factory is no longer supported in the Photoshop suite. Can someone help me to create the same filter in Pixel Bender to use in Photoshop CS5? I will share the details of the filter if someone responds.
