That wasn’t actually a gamma curve but the lossy compression scheme at work. As this was undone in raw processing (the camera multiplied by 4 and took the square root, the raw converter squared the value and divided by 4) it made no difference with regard to gamma.

... yes..yes, I did not remember well... M8 did produce that way its 8 bit raw...

The only other thing I can say is that when setting up projectors the black level and the graduation out of black 0-15% or so is critical to how the image looks, particularly depth and body to the image. I guess the question is doe the low base noise level with the CMOS sensor ( I assume closer for zero than 44) compensate for the less sympathetic response curve in comparison to the CCD.

 

Just set up a new Sony G90 CRT projector today. We can now put a card in these old projectors that accept HDMI and transcode it to an analog RGB signal the G90 can accept. The best part of these cards, besides being able to accept 1080p HDMI, is that very precise gamma curves have been created for these cars. They expand the lower end of the gamma curve because, CRT projectors have inherently suffered from crushed shadow detail which needed to be sacrificed in order to hold true black.

 

Now, with these new gamma corrected curves the projector can hold true black and not crush the rest of the shadows. The gamma correction can also be adjusted to fine tune the curve. There isn't a digital projector that can touch the black level of these 9" liquid coupled CRTs. The picture is just amazing. Nothing like it.
