Author Topic: My first accepted ISO 6400 (Read 8155 times)

Back to the debate about noise,

I got a shot taken wtih a 30D at ISO 200 accepted today (no big deal). However, an identically processed file with the same subject matter and the same exposure (literally the same shot, difference angle) got rejected for artifacts. Weird? Very. And I think the rejected one had better composition than the accepted one. So I'm not sure what the deal-io is.

Oh well, I learned 3 years ago to let it slide

i think the deal is that Canon over process the noise when you select a higher than normal ISO. if i am not mistaken, there were several articles that mentioned this.
in a camera to camera comparision, they found that Canon images looked cleaner .
much like using the noise reduction in RAW with post-processing in PS.
not an expert, but as i said, i read it in one of those comparision charts between Nik and Can.

They also reject for artifacts with iso100 with 5dmk II
Full size straight from camera no resaves.

Same with the 5d mkI - there will always be noise in a shot, especially in darker areas even at ISO 100. That's what post processing is for - as anal as it seems, I just go to town on anything I think even minutely looks like noise. Blur tool, neatimage, whatever it takes. Sometimes you can get away with it, but I personally think its better to take the time to remove anything that might cause a reviewer to hit the reject button.
