All taken with M240 + 28/2A @ f/2 1/60s ISO 200 AWB

First one is LR5 jpeg output before PP

Second one is LR5 jpeg output after PP (1-stop added, contrast reduction, perspective correction, color vibrance increase, sharpening)

PP is for the purpose of testing room for PP, not for improving picture quality.

Because of internal lighting, these test pics have wide dynamic range.

I try to see how much shadow details can be shown after PP.

My impression is that, in this respect, M240 is doing fine, very fine!

Yes, comparing with M9, M240 obviously has greater room for PP and recovery of details.

That means one can shoot more "blindly" ...
and "cook" the "RAW" afterwards

Surely K-san that's one way of looking at it.

To me, PP is a necessity in digital photography.  As far as I could recall, I don't remember using direct jpeg output since buying M9...

why the tuned pict has slightly different perspective?

BTW, I would like to see you shoot 2 stop under and pull it back up at PP for a better demonstration.  Thanks for your efforts anyway.

The perspective correction is to eliminate any distraction from viewing.  Sorry this is my personal idiosyncrasy.

In addition to adding one stop, I have also lowered contrast (which has the effect of revealing more shadow details) and added color vibrance.  To extract shadow details, I can only "stretch" a digital file so much without making it look too unnatural, or else I have to start tinkering with other parameters to make it look another kind of "natural".

As to the sharpening, I lowered the radius from 1 to 0.5 and increased details from 25 to 50.  This is for me to see whether or not sharpening works the same way as M9 DNG files.  As expected, different sensors respond differently to sharpening mask.
