Digital resolution: why enough will probably never be enough, and how to solve it

How often do we have nice regular subjects like this? Hardly ever.

The pixel race continues: more resolving power is being crammed into smaller and smaller physical sizes. The recent Hasselblad X1D announcement is at the pointy end of that: we now have medium format resolving power and tonal quality in a package that’s smaller than many 35mm solutions. I have a theory about resolution and the megapixel race and perception. Aside from the marketing reasons why 100>50>24 and must therefore be better, there are much more fundamental reasons why we feel the resolving power limitations of digital far more acutely than film. And it isn’t just our ability to pixel-peep with ease; it’s more to do with the fundamental nature of the world. Yes, there’s sufficiency in output because of the limitations of the output device itself, but I suspect these will catch up and exceed capture very easily. Allow me to explain why, and why I think there’s a way out that might well result in a very different sort of sensor…
