Bug 283628

Version:           unspecified (using Devel) 
OS:                Linux

I understand that digiKam, through kipi, already supports both panoramas and HDR via enfuse. Please can we have support for alignment+stacking, at least a simple average of all the images passed? 

Justification/notes: The most noticeable effect of stacking is that with every doubling of the number of images, in noise terms the effective ISO halves (hence astronomers are particularly fond of it). A secondary consequence is "synthetic long exposure" - all the motion-blur of a long exposure but either at wider aperture or with less ND filtration required. The third use is for super-resolution: sub-pixel realignment differences cast extra detail into the image, either beating the limits of diffraction or facilitating larger upscaling.

(For those with Photoshop or the Gimp: averaging can be achieved by loading images into layers, setting their transparencies to 100, 50, 33,... 100/n% where the background n=1.)

I, for one, would be very grateful - my workflow is increasingly dependent on stacking a handful of images together.

Reproducible: Always
