Okay, so i shoot alot of sports, with a not so great gear, and a pretty slow lens.. d40 with a 70-300 4.5/5.6 is the lens im using.. so for sports i usually shoot at 1600 iso, in the dark which does not work out so well and lots of noise starts coming out.. so i tend to remove the noise with a noise reduction filter and sharpen the pic and all that, but sometimes when there's not so much noise, on photos such as this one

i want to keep the photo, maybe remove some color noise, but noise removal always seems to blur the photo a bit.. i asked my photo teacher, and he said you gotta live with noise sometimes, because its better than no shot, i mean i keep saying that to myself, but since im so used to cleaning the noise up, i can't just live with noise.. so ya help me out guys..

I assume the moon is the main subject of this photo. So in this case, lower the exposure time so you get a sharper and better exposed moon. The moon is over-exposed in this photo by at least 2 full stops, the highlights are all blown. Of course, that was my assumption that the moon is the sole subject of this photo.

If the subject is including the clouds/mist, then use the curve function to darken the over-exposed area and brighten the darker area. With your 300mm zoom range, there is a lot of room to crop as well. I took this photo at only 200mm range:




Bottom line: faster shutter speed, bigger f/stop, and lower ISO. That'll help reduce the noise.

In case you want a comparison, the photo above is taken at 1/256s, f/8, ISO 100.

thanks, i know that lower iso and a more wide open fstop helps, but i just can't afford the gear, and the subject in my photo was the moon, but i'd want to keep some clouds in it as well, and what im saying is i tend to use noise reduction even on the slightest noise, even at full day time shots at iso 200... and i don't know how to "live with the noise" also great shots of the moon bro you gotta teach me sometime ;o

It's also due to your camera. Perry doesn't use a D40 which isn't so great at handling noise so his picture will be better in that respect. There isn't much you can do that I know of besides maybe converting to black & white? :/

OK, yeah, it doesn't have to do with the D40...I've got a D40 with the basic 18-55mm lens and I've never shot a photo with noise that bad; Figure that f**ker out...The only photos that even showed a hint of noise was because of bad lighting, and when I mean bad lighting, I mean shooting a photo in a room where the light source is an incandescent light bulb...Even my night exposures are clear, and they're on record in the photography thread...

My hunch is that you simply just can't have the moon as the primary subject using an entry-level DSLR of any kind...A full moon floods an assload of light and the camera's compensating too much on the moon's exposure and compromising the exposure of the surrounding sky which is significantly darker than the moon...That's probably the how; Why it's turning up that much noise, I don't know...

Gabzor, was the photo shot in RAW ? If not, what was the original resolution ? I would like to try some post-processing on it and see if I can bring out any details out of it.

was in jpeg, and the topic isn't about the moon! to clear it up its just how i should live with noise.. see there, my friend took it, its noisy, but i kind of like it.. but well kinda hate it at the same time.. so i'd like to know what you guys think and perry i pm'd you it

I got the PM. Unfortunately, I couldn't make it work as it was not shot in RAW. About the photo you just posted, I honestly don't see a whole lot of noise. Are you referring to the out of focus blur region to the top left / right corner ? Those are normal, usually can be fixed with a little post processing software, which usually comes with the camera for free.

And I continued to talk about the moon because it was pertinent to the correlation between exposure and noise and I made an example out of it...

Between your moon photo and your friend's watch photo, the camera models used may be different, but the photography concepts still apply...Your friend had an adequate light source in his environment, so noise doesn't show up much...I honestly don't see much noise, and what noise there are is minute (And appear only where the light couldn't get to) and could be easily touched up in a program...

I agree with MV88 longer exposures bring out much more noise than a normal picture does.
