7D Noise. Is this the normal amount of noise?

post #1 of 11
Thread Starter 

7D, 70-200 F4 Non IS
Settings: Shutter 1/250, F/4, ISO 3200, RAW

So i'm shooting some Sunday paintball and i was shooting indoors so i didn't have the best lighting especially with the fact that i was using an f4 lens. I tried shooting with a high iso to compensate for this. I haven't used my 7D extensively as i had just upgraded to this body not too long ago so i'm still learning it. My question is though is this the normal amount of noise i should be expecting when i'm shooting at 3200? It just doesn't seem right to me...i just don't know why

Holy jesus, that's so underexposed. Noise is more noticeable in shadows. Can you post a 100% crop or the out-of-camera original?

Do you really need 1/250 shutter speed? For that particular shot 1/100 is perfect and will allow you to drop down the ISO.

Otherwise, yes that is exactly what ISO3200 looks like.

Good luck shooting action at 1/100. Besides, how do you know what FL that was shot at, and whether or not it was on a tripod?

Its exaggerated by being very underexposed, leaving that histogram leaning so hard left it's not even funny.

For that particular shot, no i didn't need the 1/250 shutter but when my subjects start to run (which can be a totally random moment) i want to capture the movement. As for the underexposed post, yes i understand it's underexposed but that was the best i could do before having to bump the iso and having it become extremely grainy.

Looks like the same image as is in the OP.

if that shot was properly exposed the noise would not be too bad. My 7D at 3200 has noise but its not too bad until i get to about ISO 5000 then its pretty rough.

with any camera at high ISO if the shot is not properly exposed the noise is going to be visibly worse.

as you have already realized a slower shutter speed would have been better. but at the same time coming from someone that shoots a lot of action sports i may not have a bunch of experience but i will say that i deal with bad lighting conditions as well. but a shutter speed of 1/250 may have been helpful but honestly your lens choice for this isnt the best shooting f4 with bad indoor lighting. but paintball is not a super high speed movement sport compared to basketball or soccer where i dont shoot much slower than 1/500 if i can help it. i think you can slow your shutter speed and stay at ISO 3200 in an attempt to at least get a proper exposure and once you figure out what the best shutter speed is for indoor paintball you can then figure out what ISO you need.

i suggest next time putting your camera in shutter priority on Auto ISO and set it to like 1/100 and adjust until you get a speed that produces frozen action as desired. i will say most likely you will need to live with some motion blur since your working with an f4 lens that limits your settings a little over an f2.8 lens that may allow for slightly faster shutter speeds.

honestly if lighting is THAT bad i might consider some long primes and cropping so you can get a wider aperture if you are having that much trouble with exposure. more than likely trying to shoot in shutter priority will help you

You might want to over expose using the exposure compensation next time. Might help a bit.

You need a faster lens and/or higher ISO. A properly exposed image using higher ISO will have less noise than a underexposed image at a lower ISO.

You shouldn't intentionally under expose, because, as the others have pointed out, it will cause profound amounts of noise when you try to lift the shadows in post.

And don't worry about noise. The 7D is fairly capable in that respect and there are numerous programs/plug-ins/etc that reduce quite well. It's far better to have a sharp, properly exposed shot at a high ISO than one underexposed for the sake of not raising the ISO speed.
