Just a quick post of the Pentax K-3 image at ISO 51200 and not even the right. And don't forget, this is a completely dark area. With the camera settings at ISO 51200, the Exposure is still way low.
Below is the original image from the K-3 JPEG.
Settings for the above image are:
Pentax K-3 Firmware v1.0
Tamron 17-50 f2.8 @ 43mm
Aperture at f2.8 (Not the sharpest I admit. Should be at f4. My bad)
Shutter Speed at 1/30 sec
ISO 51200
Setting at Natural with sharpness at Extra Fine
In camera NR Off
SR on
Below is the approx 100% crop
Not sure is it whether the focusing screwed up at this pitch dark enviroment or the noise are just too massive. Would be sharper at f4 I recon.
Done a bit of brightness on the JPEG with Post Process
You wont want to make prints larger than 4R with this image do you?
And a 100% crop
Yuks......... Now it gets even worst. What if I use the RAW files and see what Adobe Camera Raw can do? I know is not hte best for this kind of recovery.
RAW After NR
Approx 100% Crop
So the conclusion is, although its almost unprintable at this high ISO especially in extremely crappy lighting or none at all, it still captures the image with decent details. Like I say, could have been sharper at f4 but on the other hand darker. So is a trade off. At least I still can see the cat figure rather than just a piece of junk when zoomed in.
Cheers and take a break............
