comment Can a Sigma dp3 quattro be used for Macro Photography?
I meant Superresolution. Maybe it can be used here for noise reduction and some resolution improvement. Never tried it, only know that this method exists. Didn't remember its name yesterday. To me it's like focus-stacking with focal plane held constant, and then different algorithms applied.

you will have to crop the image massively - but the foveons have such high resolution- I speculate there are still more than enough pixels left after cropping - that was the basis of my idea.
