chromatic aberration the new bloom lighting. It needs to die

Can you show one photograph that makes good use of chromatic aberration. All I can find online is how to avoid it.

There are a lot of popular effects in movies, yet I don't think chromatic aberration is one of them. It's been showing up more since the move to digital cameras that suffer more from chromatic aberration than film.

Anyway it seems dusty lenses are on the retreat, that got quite bad at some point as well.  Except in VR when my glasses and the headset are dusty, no need to add it in game as well :) CA will go too once the next unwanted effect becomes the new thing.

It's not a sensor vs old fashioned film issue.

It's a lens issue, most lenses that people buy today are crap (given they are much cheaper then they can be) and one sideeffect is more CA.

 

Otherwise you are on piont, CA is never a wanted effect in photographs.

Digital sensors contributes to the problem, it is mostly lens though.

A digital camera quantizes the light more coarsely than a piece of film. Consider if the lens has 3 microns of chromatic aberration. ... 3 microns is enough to significantly spill into the neighboring pixel, so the amount of chromatic aberration appears to have doubled compared to film. They also see color differently.

A better lens will of course help more than switching back to film. With film it also gets more easily lost in the grain. Digital pictures are already far higher resolution than (normal sized) film was capable of. Any defect will show.


Another popular effect that's sometimes overdone is color tone changes for scenes. It's very weird to walk into another section and the color artificially changes. Simulating lens filters perhaps.
