Some of my shots seem to have an excessive amount of noise.
Same lens a few seconds later.
that looks like the noise you get when you 'save' an underexposed pic.
Ahh...yes you are probably right.
I think the camera or the raw editor will always try to attempt noise reduction even if you try to tell it "NO!" So since it is try to NR an area already free of Noise just purposely dark it now looks like noise.
I think the arm hair triggers the noise.
(sorry, someone had to say it)
What do you use for process?
where are you even seeing noise? Theres like nothing
underexposure is the kiss of death
compare garage and asphalt of pic 2 and 4
Trusting you LCD ftl. Look at the histogram. You shoot RAW, so I would suggest overexposing 1/3 - 2/3 of a stop (according to your meter) and recovering downward in LR or ACR etc. Pulling abundant information down from the highlights is much better than pushing minimal information up from the shadows.
not when its all white. watch that you dont get too much clipped at the end of the histogram.
"Expose to the right."
Look at your histogram when you shoot. Try to expose so the histogram is as far right as possible, without blowing the highlights. If you're shooting raw, you can probably even clip a little.
in print you won't even notice that noise
Some school of thought suggests that you never want to clip the highlights. I guess it's a matter of tastes. I'm still trying to figure out how all the 1's and 0's react to different set ups.
I typically do check the histogram from time to time. What happened in this instance was that I accidently turned the aperture wheel with my thumb and didn't notice it for several shots. I know I can lock the wheel out but it's a pain to lock then unlock when I want to change apertures.
I need to buy a AHR filter!!
I use Lightroom.
Yeah, you don't ever want to clip the highlights, but it's easier to bring down something thats *slightly* overexposed than to bring up something thats underexposed.
There's a HUGE difference between clipping and overexposing. You want to play inside that difference.
Idealy, the bulk of your histogram will be in the right 3rd of your histogram.
well, we can see what the "underexpose school of thought" method does when you correct. RAW highlights are pretty easy to get back, especially if they're within a stop.
