To use the Astro Filter Pack you need the application called CamTwist which you can download for free on the developer's web site. The developer, Steve Green, only asks for PayPal donations for this awesome utility, so please send him some cash!

After downloading the filter pack file below you will need to drag the files into CamTwist's "Effects" folder.

These filters are all free, but if you'd like to make a donation to fund development and improvements, then please make a donation of any amount that you feel is appropriate via PayPal:
