focus stacking in photoscan
« on: June 09, 2012, 01:00:24 PM »
i am doing some experiments with objects in the macro range, and this technique is used in macro-fotography to compensate for out of fokus areas:

would it be possible to feed photoscan processed images using this technique?
the exif-data would be lost of course.
also, photoshop has to distort the different focus layers in order for them to fit, meaning Photoscan wouldn't have a single value of "f" to work with.

what do you guys think?

I tried it and it works.. I used Helicon Focus which keeps the exif in the final processed image..

hope that helps...

Yes, it works fine with images processed by Helicon Focus :), but, of course, higher is the magnification more shots you need and you quickly get a big amount of photos : 211 shots for producing the 11 images on which is based the joined example, taken at 1.5:1. The point cloud is rough from Photoscan, as seen in Meshlab.
