Hi all,
I'm wondering if it is posible to save, as a grayscale image (even at the lower resolution of the 'silent picture'), a representation of the object distance from the camera. In alternative, the representation of the focus position.
For reference I link this page from Wikipedia, that contains a couple of images that could explain much better what I mean: http://en.wikipedia.org/wiki/Depth_map
I think this information could probably be derived with the same process used to draw the focus peak marks, probably with no need of changing manually the focus point.
The resulting image should look like the z-channel in 3d graphics: http://rbcdn.polytown.netdna-cdn.com/wp-content/uploads/2010/04/making-gh-house-ivo-sucur-interior-wireframe_zdepth.jpg or http://www.intiaz.com/wp-content/uploads/2013/04/zdepth-photoshop-1.jpg
With this kind of image, saved together with the original picture, one could change the depth-of-field, simulate fog in a proper way, etc...
Thank you,
Federico
