Hi guys

Been shooting some kids nursery today, with consent obviously, I'm just going back though them now (i can't post any on here for obvious reasons) but when i go full res, there is quiet a few that are grainy.

Been shooting on Canon 5D Mark 3 with 24-105mm at mostly F4 ISO around 1600 at roughly 1/60 - 1/125

lighting has always been pretty good. Most of the shots are outside, and if inside I've been using a flash bounced off the ceiling set to 1/64 usually.

any thoughts?

1600 was the best way to get everything with the light of the day. Better to have gone lower?

If you need ISO 1600 you need ISO 1600, you just have to put up with the noise. I doubt it is visible at regular print or viewing sizes.


The last event I shot was done at ISO64000 thoughout.
 
What's the purpose of the pictures (as in will they be for a website or printed or whatever)? I can't imagine ISO 1600 on a 5Dmk3 will be horrendous unless it was really dark. If it's for the web then by the time you apply a bit of noise reduction and resize it, I imagine it'll be unnoticeable.

Yeah, it can't be helped unless you try to tone it down in Lightroom.

If you're going to use a lower ISO, you'd have to use a slower shutter speed which doesn't really work with kids running around everywhere in a nursery.
 
I wouldn't been too bothered about ISO 1600, that will be acceptable on MKIII.

If you don't like that then use a 2.8 lens :)

D3s and D4s go to 102k and 409k ISO respectively :)

Have canon got to 3200 yet ? :D

Max ISO could be 1 million but if the results are crap then it's worthless.
Remember, high ISO doesn't just increase image noise, it also reduces dynamic range, colour and tonal information.
Use the lowest ISO as you can to get the shot and avoid using ISO in the extened range setting.

"Crap" results are better than no results, i'll use any ISO needed to get the shot.

I was just having a stab in my previous post, but Canon need to stop farting around making sensors and move to sony if they want to compete :)
