I am just wondering if anyone knows how to recreate the instagram lux effect with photoshop,
here is an example of before and after of the lux effect
I borrowed your image to try it in Image View plus more 3, which I made myself so I know all the underlying algorithms.
I think this is pretty close, albeit the colours may be a bit different (my weakness as I am colour deficient).
What I did was:
Local contrast enhancement. Adobe calls this "clarity". It is similar to the unsharp mask with a very large radius.
Boost saturation. My program does this in the Lab space. Other software may do this in other spaces (e.g. HSV) which can result in different colours. It may also be a selective saturation boost like a proprietary "vibrance".
But I would conclude it is these two operations that is incorporated into "Lux"; a local contrast enhancement, and a saturation booster of some sort.
