Eric that is what is so good about this method it uses Masking so you have 100% of control look at my pix on the new 500mm lens blog of the Snipe with a drip, noise removed 100% from BG but not on the bird.

jk wrote:Graham, it might be useful if you could detail the steps you took to improve the image. With respect, we should be able to take photsos that don't need rescuing with computers. That was the thrust of my argument.  All the images I posted have had NO digital witchcraft applied. There are many ways that visible noise or jpegging artefacts can be reduced. They all achieve this by some degree of image softening. That can't be right? We spend thousands of pounds on the finest optical equipment only to soften the images to hide noise? I have my own selective noise reduction method (reposted image below). Although it only takes a couple of minutes....it's time I would rather not have to spend masking sensor limitations.

So does mine Graham. See above. But I would question the result you got on my Coal tit above because to my eyes there is loss of detail on the bird? It's got that 'fresh make up' look I mentioned before. I am sure it's a question of degree whichever method you use. The point is ....we shouldn't have to be tinkering with the IQ of a captured image. Never did it (or could do it) with film. Sure we could do selective exposure adjustments and even introduce grain effects during film processing. But darkroom sharpening and removing grain were all signs we miss handled focus and chose the wrong filmstock in the first place.

The Blue Tit I posted above has no noise reduction on it. Cropping is the biggest way to highlight noise in a image thats why my view is if the bird, unless its rarity, is too far away I wait for a better opportunity.

This is 1/1000 @f8 and 2200iso with D500 and 300mmPF lens with no editing apart from crop 50% Attachment: DC0E962A-BAEB-4069-B674-19A37EDCF24D.jpeg (Downloaded 9 times)

I've had a few people say that to me Eric. I must have a good copy of the camera. I showed a few shots at 5000iso at the camera club I run and some people couldn't believe it.

For a while `I wondered if it was the fresnel lens...which does impart a different boketh to conventional lenses. But yesterday I did a comparison with a conventional lens albeit a tad shorter than 300mm ( but adjusting shooting distance to match) and there was very little difference in noise. It's clearly a d500 / sensor issue.
