Teph's Tricks

I've made a few plug-in filters using Filter Factory. These filters are usable by Paint Shop Pro and Photoshop and any other paint program that can use *.8bf filter files. If you get errors about missing files or incorrect installations you are probably missing one of these DLLs in your windows/system directory.

To download a filter right click on the link and choose 'Save target as...' To install a filter just unzip it into your plug-ins directory (I recommend using a subdirectory called 'tephs') and start your paint program. Make sure your paint program is set up to search subdirectories for plug-ins!

Light Half - Convert color 'lightness' values under a sliding threshold value to a value above the threshold (50 with a threshold of 100 becomes 150). Red, Green, and Blue thresholds are set independently. Light Half
Weighted Light Half - Rather than just adding the threshold to the values under it this filter subtracts low values from the maximum value (50 with a threshold of 100 becomes 205). Red, Green, and Blue thresholds are set independently. Weighted Light Half
Dark Half - Convert color 'darkness' values above a sliding threshold value to a value under the threshold (150 with a threshold of 100 becomes 50). Red, Green, and Blue thresholds are set independently. Dark Half
Weighted Dark Half - Rather than just subtracting the threshold from the values over it this filter subtracts the high values from the maximum value and uses the result (205 with a threshold of 100 becomes 50). Red, Green, and Blue thresholds are set independently. Weighted Dark Half
