For static or semi-static scenes, there are many ways to "simulate" certain features actually not feasible on single photo using the technology the photographer has. For example,
- wider field of view by taking multiple shots in adjacent directions and stitching them into a panorama;
- deeper DOF by focus stacking;
- lower ISO by averaging multiple frames;
- higher dynamic range by merging differently exposed frames into a HDR image.
This makes me wonder, is there any way to use multiple exposures for creating shallower DOF at a given field of view, normally achievable with a faster lens or a bigger sensor. How to do that?
I know it's kind of stupid to start out with a hammer and then invent how to carry water with it... but I stil wonder.
