Adobe Photoshop CS3 Autoblend fix
Adobe recently made Photoshop CS3 beta version available for Mac and Win to CS2 customers.
The new release has tons of new functions but there's one unexpectedly useful for the panoramic photography community: autoblending.
Autoblending is extremely precise and much faster than the older blenders we are used to.
Panography guru Hans Nyberg has compared CS3 autoblend against the most commonly used belnders: enblend, smartblend and PTGUI. The results are amazing and CS3 wins easily in terms of speed and quality of seams.
Unfortunately there is a limitation in the use of CS3 for panoramas. It doesn't blend over the 360 degree wrap. After a month of proposed complicate solutions for an easy problem, this minor lack of function can be solved with a 3 step method:
1. Save two equirectangular layered panoramas, the first as it is and the second with a 180° offset
2. Autoblend the two panoramas in CS3
3. De-offset the second panorama in CS3 and merge the perfectly blended sides on top of the first panorama
