Re: Stereo-3D Anaglyph Panoramas
- Hello Roger,
Perhaps this is the thread that Jim is referring to:
It is this thread (by Peter Murphy) that pointed me to the idea to use a lot of images
to avoid retouching issues in Photoshop.
Luckily the high number of images I need (at least 2 x 25) is not so bad as it sounds, with the help of a Photoshop droplet the canvas of all source images is trimmed to 1/3 of the original width, this save a lot of harddisk space and PTGui processing time and 1/3 of the original width is enough to automatically place CP's for optimizing.
