Hi all, just went to start processing some images and there seems to be something wrong with all my images, lots of noise!

Here's an example...
9720767341_838fa6e2fc_h.jpg


100% crop of one of my images, only opened in lightroom, no changes.

My 60D is only about 4 months old so warranty is fine, just want to make sure first.

Iso125 / F7.1 / 10mm 1/320s, it seems to be in all dark areas on my images, i'll find another example.

It seems like it can't render black properly to me.
 
Do you work with laptop? Do you look up from keyboard level and then see more noise? It is then time to shop for IPS type screen...

I can't see any noise, just pure blacks. But I can see lots of CA and that looks bad

Oh, and you can make 5DIII look really bad in shadows - just pull exposure a couple of stops
 
I found the intermediate ISOs seemed noiser than the standard ISOs (more processing?).

Once I'd changed to only using the standard ISOs is thought the noise was better? It could have been my imagination of course!
 
I think it could actually be my gfx card on it's way out :(

There IS noise there but I doubt if your card is responsible since noise in deep shadows is quite common even at low ISOs.

My own editor sometimes shows up a lot of noise at lower than 100% crop - this seems to be an anomaly which I know about so generally ignore - what are the pictures like when they are edited?

.
 
Simple way to work it out, have a look at your photos on a different screen - friends computer, office computer, whatever and see if you can still see it.

Several years ago now I used a windows laptop and every picture looked like ISO32000 during its dying days, even though I know there was nothing wrong with them.
 
It's "color noise" and typical for a digital sensor. You should be able to remove it in the sharpening panel w/o significantly affecting detail.

IMO you should always start by removing color noise before reducing ISO noise.

On many cameras the intermediate ISO's are digital and not analogue or it's a second stage of gain... More common w/ Canon than Nikon.

Select your camera from the menu and check out the plot.

Hi Wez, are you used to using a different camera? There doesn't look like a lot of noise to me there - but if you've been using a camera based on a newish Sony sensor those deep shadows is an area that they win.

I think it's a pretty good result considering how dark the screenshots are in the image.
 
hi, wez I have just been looking at some raws I have of when I owned a 60D and comparing them to what you have posted you do seem to have more noise although not much more and your pictures do look sharper but it does appear to be colour noise, Do you think you have some settings on your camera like for shadow detail turn up high or sharpness or something else? set them to default se if that helps.

Blacks look fine to me.

Is your screen calibrated? Badly calibrated black level could explain a lot...
