No, we don't apply any sharpening to "our" raw images captured, never. That has never been our idea to simply make look images better for users (or potential users, speak for "commercial" reasons).
Your Adobe document is very interesting and explains well what happens in the shadows and highlights areas. I can only insist on the "exposure to the right": it is absolutely the right way to avoid or lessen problems in the shadows and that is what Sinar is doing. But there is no S-shape curve applied here.
Yes, you are right: the Sinar .STI files do also have a "curve applied". But the curve which is applied is only applied when you open the document (or then in the preview/thumbnails, for obvious reasons). The RAWs on your HD are absolutely untouched.
And the curve applied is the one from the used "Working Space". But there is no "twicking" of the shadows or highlights like it happens with some other digital cameras by applying a tonal curve.
However, the Sinar eMotion files (which are made of a ".IA" = Image Archive and a ".BR" = Black Reference) coming out of the back are absolutely raw files. Those absolute raws are used when taking the "Brumbaer eMotion DNG Converter" from Stefan Hess: during this conversion you might then apply some "Colour Matrices", "Highlights Recovery", "White Shadings", "De-Noise" of the shadings, etc ..., but this DNG conversion uses absolute raws.
Thanks for your compliment.
Best regards,
Thierry
The "linear curve" is really the "default curve" as there is a gamma correction curve being applied in order for the image to make some visual sense to our nonlinear vision. Adobe Linear Gamma PDF
It is surprising that "Sinar CS DOES NOT and NEVER apply internally (in the software) any sharpening" as RAW conversion programs generaly apply a small amount of sharpening so that the initial image generated is not excessively soft.
By the way, thanks for your postings here Thierry. They are among the ones most worthy of reading.
