Poor Noise Performance
I recently switched from Photoshop CS2 Camera Raw to C1 Pro 3.6.
The reason I switched is because of the great ETC colour profiles for my 20D.
I'm very happy with the results at Iso100 - 400. But, Iso800 and above produces some very ugly results in C1.
First of all, you get some very ugly banding, almost looks like dithering.
I discovered this can be remedies by turning down \"Noise Suppression\" all the way to the left (off?), and by turning up \"Banding Suppression\" about 3/4 of the way.
There are 2 problems at high ISO's that remain though.
1. Say there is a picture of sombody's arm over a solid background, the edge of the arm almost look like parts have been \"chewed\" off. Very ugly edges that are very noisy. The only way to fix this completely is to turn up \"Banding Suppression\" all the way, and turn off all noise reduction including colour. This leaves alot of noise though.
2. Even with everything tweaked as close to perfect as possible, C1 Pro's noise reduction leaves ugly white dots in solid areas, especially black. If you do any type of post sharpening, say for print, the white dots are even MORE apparent.
I have to say that PS CS2 produced MUCH cleaner images, with smoother edges, and open solid areas at high iso's were perfectly clean. Is there anything that can be done to fix this?
Here is an example of the \"white noise\" that is visible on a ISO1600 image from C1.

I agree with drisley word to word.
I use Canon 1DMkII with ETC profiles.
Recently I have begin to shoot in high ISO (800-1600) and the results aren't as good as expected.
The images are detailless, dificult to adjust color and the edges aren't defined.
I have tried other programs and got very good results with Adobe Camera Raw but its workflow is bad (adobe Camera Raw 2.4)
Is anything we can do to improve these results?0 -
I had the same problems with my new Nikon D2X on all pictures above 200 ASA. High ISO pictures of the Canon Mark II had been much better. It may be that C1 has problems with the \"lots of pixels\" cameras? At the moment I gave it up and use Rawshooter wich doesn't work as fine as C1 and doesn't have the same nice colours. But it is much better in removing the noise! 0
