Sigma sd Quattro - ISO 100 device noise profiles and filter settings preset (updated)

I've added another device noise profile, taken with the high-end Sigma 40mm Art lens, and renamed the previous preset to indicate that it was taken with the 35mm Art lens. I've noticed that when the profile taken with the 35mm Art is used on pictures taken with the 40mm Art, the accuracy is around 9...

Sigma sd Quattro - ISO 100 device noise profile and filter settings preset

Download Important note: This profile is only for X3F files processed in the Sigma Photo Pro software and saved as TIF. Recommendations: If you want to get maximum quality for your sd Quattro pictures, set these settings to minimum in Sigma Photo Pro: Detail, Sharpness ("-2.0"), and of co...

Re: Device profile quality - around what level should it typically be when doing things right and using a high-end monit

I see, thanks. There's actually no lossy compression, but maybe it's something in Sigma's raw processing that's causing this lack of uniformity. I set all of their lousy processes to minimum - "Sharpness" at "-2.0" which actually equals 0 / disabled, "Detail" at minimum...

Re: GPU Performance, GTX, RTX, 70, 80, what?

Just mentioning that support for RTX GPUs was added soon after, in version 8.4 (Feb 2019)

Device profile quality - around what level should it typically be when doing things right and using a high-end monitor?

I've made many attempts to surpass quality level 96% when creating a profile for a Sigma sd Quattro, but it's apparently impossible. Using version 8.5.2. I consistently get either 96% or 95%, Fine Tuning Completeness 93%, and Very Low frequency value of 0.54, which gives the warning "The noise ...

OpenCL acceleration on Intel HD 4000

Acceleration on HD 4000 may not be huge, but I'm sure it will be significant. Very significant benefits in decoding, encoding and other processing (video filters such as SVP) have already been proven on it. Please add support for it. Needless to mention, HD 4000 is extremely common, as well, so it s...
