While waiting for a response, it seems to me that you are referring to a particular PGA which has four input control lines - hence 2^4 = 16 gain levels. However, having 16 levels does not tell us ...

Testing was on SPP 5.5.3 - default settings except sharpness - there is no "banding" control in 5.5.3. I have no idea but, in general, de-noising anything usually applies some form of smoothing ...

Iain, it's the gap between the highlights of an average exposure at the sensor and the sensor saturation level ("well full"). The older digital ISO saturation-based measurement added a half-stop ...

Beware the 'x' model has lower headroom at any ISO, as you probably know. My DP2s was really good in that regard.

Hmmph!

No. I agree that review images are over-sharpened by SPP with Merrills. All my Merrills showed an overshoot in QuickMTF edge response at 0.0 sharpening. Testing raw, JPEG, TIFF showed almost no ...

Agreed - I was obtusely making the point that the meaning of "analog gain" was not clear in this thread. BTW, not every camera has a PGA. For example, many Sigma cameras. The sensor output for the ...

It opens and converts correctly SD9, SD10, DP1 and SD14. All later X3Fs convert to an incorrect bluish rendering. Alternatively it can be set to open the embedded JPEG but not on SD9/10.

Pardon the cynicism, but Auto WB must have advanced considerably since the bad old days of the 'gray world' method! - what you got is not what you saw ...

Which I do not: https://www.dpreview.com/forums/post/66648986 As has already been said. And sometimes not so easy: https://www.dpreview.com/forums/post/66650202

What you are missing is that re-sampling an image changes the data in a non-recoverable manner. for example, if downsized 50%, saved, then upsized it 200% the upsized image would be different than ...

Or export directly to PNG for images to compare here.

In most Sigma cameras that have optional color modes, 'Neutral' does make a 3x3 matrix correction after going from cam raw to XYZ - that is to say that the matrix is not an 'Identity' matrix, in ...

Would it have to be a circular polarizer, Scott? https://ehabphotography.com/linear-vs-circular-polarizing-filter-why-do-i-need-one/

Understood. Indeed and that is as it should be. Do you have a color-checker card which you could shoot with both cameras in question and post the results? Edit - I see you posted something earlier ...

Terminology strikes again: To me, color accuracy is ... how close to the subject color is the reproduction? For example, if the red patch on my x-rite mini color-checker is reproduced as sRGB (D65) ...

Not knowing what "Alamy" is, I went there and found, not surprisingly, that all their catalog images have no EXIF, according to my reader.
