Denoise (profile) removes to much details for my taste so I have to use
denoise (non local means) and the equalizer
to get best results.
To follow up the case further. The problem is on raw images from noisy
cameras like Canon 7D on high iso levels.
Give me a couple of days and I will dig in my archive and find those
problematic raw images, if I still have those shots.
Basically the problem was in images with iso 3200 and greater.
On other camera systemes with a different sensor like Pentax, Sony og
Nikon this is a non existing problem.
Canon sensor don't handle noise very well and the raw files is a pain to
process i Dt.

'Hot pixels' is exactly an 'impulse noise reduction' filter, you can
lower the threshold if it doesn't fit your needs. Apart from that, you
only have to use the 'Denoise profiled' (which as something like 2
useful sliders, and often works out of the box), so I don't quite see
why the situation is so different from LR. I don't realy see the point
in introducing yet another noise reduction module.
Benjamin
developers a message.
And yes I have tried before. The message is clear. Dt have to
improve in
this field.
And yes also I have also tried to use 'hot pixels' module several
times
but it don't always work.
I hope that some of you have experience with other raw processor. But
this is the situation.
Lr have none of these problems and do a perfectly job with only 4
sliders. Rawtherapee solves
this by 6 sliders in noise reduction and the white dots are removed by
Impulse Noise Reduction
filter. Both raw processor do a perfect job.
The most easy solution in my opinion is to add a Impulse Noise
Reduction
alike tool.
