While handy, focus stacking requires taking multiple images which means you're limited to static subjects only. If I'm not mistaken, the proposed new approach can just as well be used to take pictures of moving subjects.
- droopyEyelids 5y agoI wonder if instantaneous focus stacking could be possible with a module of cameras.
- moffkalast 5y agoYeah if you had multiple sensor outputs with different known fixed focuses it could likely be done on the fly.
- Etheryte 5y agoThe limiting factor here is that you need your lens to shift focus. So if you wanted to take a-la five simultaneous shots for focus stacking you would need five separate lenses at different focal distances. Since five lenses can't occupy the same physical space you're going to end up with five slightly different perspectives. It might be possible to computationally correct the perspective between them to a certain extent, but I'm not sure how good the end result could theoretically be.
- droopyEyelids 5y agoIt could also be done through partial mirrors and prisms, but would of course require a brightly lit field or suffer ISO tradeoffs
