Over 50 is not good IMO. Thank you for sharing! The Adobe Ai denoise works impressively well and i feel better than i did it manually with the older denoise sliders. However, is it only me or do you think that there is a lot/too much noise in the photo above considering that it is a SL3-S and "only" 6400 iso? Is there a particular reason to not go over 49% as softening will be greater or just a personal believe that max denoise should be below 50%?

Ken Abrahams Posted February 2 Share #42  Posted February 2 (edited) Hey Chris, I go over 50 several times because some images need that. Other images do not get treated with Denoise at all because there is little difference in the preview plane. Even if the image shows a bit of noise I refrain from using Denoise at the beginning because I can work with it at the end of the workflow. I prefer not to alter the grain structure and prefer to use Denoise only with extreme cases. I quite like the grain of the SL3, SL2S and SL3S and when I was using the SL2 I tended to use denoise a lot. The image of the pole was at night and across the road so very contrasty lighting. There is greater potential for grain in dark shadow areas compared with a brighter scene using iso 6400. Yesterday I had a tricky lighting set up with shadowy areas and bright sunlight background. The subject was travelling at 60-70 kph so I needed a fast shutter speed. I shot that at 1250 iso and not a bit of grain evident.

Chris I think the softening is getting too strong about 48. Make some experiments to find the best balance that you are still fine with. Myself works usually in 30 range only to keep it sharp. Pretty often I prefer too, to keep some noise. Edited February 2 by mpauliks 1 Link to post Share on other sites More sharing options...

This was in Costa Rica and I believe it is called the green basilisk lizard. A gorgeous creature and the light was just right. As a side note; forgot to add that this was with the Sigma 500 f5.6 lens - it was very impressive and the most used lens on my trip to Costa Rica in January. Highly recommended lens! Brad 1 1 Link to post Share on other sites More sharing options...
