Haze removal filter : is it functional ?

Recommended Posts

The first time I wish to use this filter. I do not see any effect on my picture (tiff, 16bits)... nothing, whatever the cursors position (of any cursor).

A chance to have it functional and as a live filter ?

Seems to work here. I've attached 2 samples. The first is the developed CR2(Raw) file, the second, the 16bit Tiff generated from the Raw file.

It would be nice to have the Haze Removal Filter as a Live Filter.

Thanks Ron for your reply and testing :). Clearly, it works for you... no way in my hands. I start again the PC and further test it.

First, I thought it was  a Live filter but since (i) it is destructive and (ii) we can not apply a mask to it, I find less easy to use it for editing.

@Pattou,

So the question is why it's not working for you? We're both running Win10, mine is the Home version while you run the Pro version. I have an older Nvidia graphics card. Those 2 items are about the only things I can think of that might have a part in the Haze filter's behaviour being different. Have you tried pushing the Haze Filter's adjustments to the max just to see if it is working at least a little on your images? With one image I tried this on I had to, since there really wasn't a lot of haze for the filter to work with. Just a thought.

I was trying the Haze Removal Filter yesterday and first I thought too, it has no effect. After playing around with it for a while, it seemed it works a bit wayward - only with the pixel layer selected (destructive).

Ok, I could see an effect and indeed, the effect can be very (very) weak on some of them. However, on some pictures which display a kind of haze, I could not see any effect.

I was maybe wrong thinking that this filter should anyway increase the overall (micro-)contrast....quite different of what I could get in the past with Lightroom.

Thanks all for your advices and testing ;)

Cheers,

Patrick

Suggest you duplicate Background layer, before applying Haze.  This allows you a measure of security as a non-destructive layer.  Just delete the duplicate layers if results are unsatisfactory.
