This is great - I'm very impressed and thankful that you implemented this feature so quickly.
I have tried it out now and it works very well.
Thanks a1ex, good job!
Thanks also to nanomad for the nightly.
Now, this may seem like nitpicking but it might be preferable in this case if you could choose the sequence " - 0 " . For example, when shooting a portrait it would be better if the shot with the shortest shutter time would be taken first, to minimize the risk of the model moving between the shots. A minor detail for sure, but worth considering.
engardeknave: That's right, however:
b4rt: That's a correct observation. You have to use your artistic sense. - sometimes it's better to leave the edges from the blurry image to have a smooth transition, and sometimes it works very well to mask a few pixels outside of the edge. In that case, you will get a part of the sharp image where it 'shouldn't be', but oftentimes that is not visible.
I find it quite easy to get good results quickly.
The merging is of course easiest with pictures such as portraits where you have a single sharp object against a blurred background.
