Originally posted by kositoes Because i mainly take images of birds(sigma 150-500mm hsm) i usually need to have a high shutter speed... i tend to hover around the 1/500 - 1/1000 mark and as such only shoot in the brightest of conditions.I also use RAW almost all of the time and the ISO rarely goes above 400....but the noise is there and very noticable, I thought this was an improved sensor.......
Does anyone have any thoughts suggestions?
Dont get me wrong about the K7 though,this is the only fault I can find!!
Hi kositoes,
I'm mainly a bird shooter, and I rarely shoot at 1/500-1/1000 shutter speeds. Much more likely, I'm shooting at 1/200 -1/100, and try to keep the shutter speeds up faster than 1/125 if I can when handholding at 500mm and shorter. Longer than 500mm is usually from a tripod, but the 1/125 floor still holds in order to keep subject motion at least reasonably controlled. Yes, a percentage of shots are ruined by subject motion, but as long as I get some good ones, I'm usually satisfied.
I try to shoot at ISO 400 or lower, but it's not unusual for me to use anything up to 1250 -- and I'm shooting jpegs. In PP, I usually select the subject and apply some form of NR to the rest of the frame, and don't do much to counteract the noise in the subject in most cases -- in a print, the noise looks more like texture in the feathers, and is most objectionable in the background, IMO. YMMV. . .
I think too much is made of noise -- in prints, unless they're very big, a lot of noise is irrelevant. At normal viewing sizes on monitors, it's also just not that big a deal. For just a slideshow presentation, I'll downsize the images so they display faster and take up less storage -- this will also have the effect of reducing the noticeable noise, as long as you don't exacerbate it by sharpening too much. For posting, I downsize even more, and selectively sharpen only the subject to give it more separation, and the additional downsizing usually totally eliminates noise from the background. It usually takes a while to get the whole process down, so the best advice I can give is to PP specifically for the medium that you're planning to display on, and then work out a routine that suits this medium, instead of pixel peeping at 100+% on a computer screen.
