Here's a teaser, there's a lot more to come but I figured it would be interesting to see some results from my raw file collection of dark shots put together to compare.
On this pagehttp://a2bart.com/tech/5d2vs5d3.htm
You'll find a link to see a 5D Mark II compared with a 5D Mark III, a 7D, and a little consumer Nikon D5100.
All shots taken in manual mode, Daylight WB, 1/200s, f/16, all in-camera noise reduction disabled, all in-camera tone-curve tweaking disabled. lens cap on, in a dark room, viewfinder covered, LCD display off.
Raw files all processed with ACR using black clipping level set to 0, +4 EV exposure comp to make the noise levels more visible (and this is a range of shadow pushing that is possible). Adobe 2010 Standard image processing chosen for all bodies to hopefully normalize color response.
We can now get a better idea of low ISO DR performance of these 2 Canon icons at least at the black end of the test.
And then there's that bandy little 7D...
Now I need some sleep.
Anyone have a D800 or D4, D700, D3, D3s, D3x, etc., they can knock off some raw files for me to add to the mix? If so, send me a message.2012-04-03-1310mst update - the error with the 3200 iso 5D3 tile should now be fixed. Thanks for the sharp eyes out there.
Meanwhile, anyone new to the thread can have fun with the 200 ISO guess-who below.http://a2bart.com/techimg/dknz/200isoguesswho.jpg
