During the COVID-19 lock-down I have been trying different techniques for capturing and processing images. One of the things I have tried is the new Canon Cloud Processing made available with the release of DPP version 4.12.10. Cloud processing is currently restricted to 1Dx III images with ISO > 3200. The only process currently available is 'high-performance noise reduction'. A RAW file is sent to the Canon Cloud Imaging service where the noise reduction computation takes place and then the image is returned to DPP as a 'CIP' file which can only be read by DPP. The CIP image can be converted and saved as a 16-bit TIFF for finishing in DPP or exported to Photoshop for finishing.

The DPP User Manual gives few details on the nature of the noise reduction so I can only speculate that it is computationally intensive requiring a powerful computer and it probably uses proprietary knowledge characterizing the sensor noise profile. The image shown here is my first attempt using the Canon Cloud service. I chose this image as it has a lot of red and blue parts which are the most difficult colours to process. This is because there is only one red and one blue pixel in the four-pixel sensel making up the unit cell of the Beyer colour filter array. These two colours are spatially under-sampled and have more noise than the green channel.

The resulting CIP image looks very good and was better than I was able to achieve with Neat Image noise reduction that I regard as the best available third-party noise reduction software. The image shown here is from a crop 3133 px wide downsized to 1800 px and output sharpened using PS 'remove Gaussian blur' (radius = 0.3 px, amount = 50). No selective area adjustments were used at any stage of the processing. I think the outcome of this first trial is very promising and I hope Canon Cloud processing is made available to more cameras.

Looking at the image as you have posted (which I appreciated is not a fully edited image) the "Reds" and "Blues" appear to be blown out in the highlighs and do not contain the level of detail which is typical of your images. Is the new noise reduction process an "all or nothing" process or do you have options to specify the areas to be effected and / or the ability to specify the level of reduction? It would be interesting to see a 'before' and 'after' histograms to see if the new noise reduction process has contributed to this effect and whether the is any change when using your 'normal editing process' as compared to the Canon Cloud process. Looking forward to further updates as you gain further experience with the new process.
Ian Wilson	2020-08-01 02:28:36	Hello Bob, Thanks for your comments. Regarding the highlights, I have posted another contribution to the Critique Gallery that may help. The level of detail is largely determined by the amount of capture sharpening applied; I applied a minimal amount for the camera and the aperture of the lens. It can be sharpened further but that would result in over-sharpening in my opinion. The Canon Cloud Processing is applied to the entire RAW image from which the image submitted was a crop to 3133 px wide. When the CIP image is returned to DPP from Cloud processing there is a special noise reduction slider that can be used to fine tune the amount of noise reduction. Selective area adjustment using the Cloud processing is not available as far as I am aware. In my normal noise reduction workflow with Neat Image I use selective area adjustment, typically more noise reduction on the background and less noise reduction on the bird. I also used a different amount of noise reduction on the red and blue colour channels in this example although that is not usually necessary.
