Shutterstock - "Noise" Rejection, How to clean up the sky

(1/4) > >>

maco0708:
I just got this image rejected at SS:

Here is 100% crop of the sky:


Rejection: Noise--Noise, film grain, over-sharpening, or artifacts at full size.

Tech details: Canon 40D at ISO 100, processed from RAW. It was correctly exposed. Lens: 17-40L shot at f/8.
(I don't really know how else to improve my equipment other than buying a Full Frame camera).


So my questions:
What do you think is the rejection reason? Noise or artifacts?
I think I will downsize it to 4MP and resubmit it. Any other suggestions?

In general, what do you do with noisy skies (Do all DSLRs have some noise in the sky?)?
(I could clean it up in noise ninja but then I would probably get a rejection from iS for overfiltering.
So, what is your workflow for similar images (brightly lit landscapes and lots of sky)???

FYI: The image was accepted at iS and FT. I think SS is sometimes little too strict on the noise for their own good.

takestock:
I've had a few rejected recently for same.
I think when you throw in something with a bare sky you are really running a  higher risk of rejection.

But, on some previous rejections, I have took out the noise and they were accepted on second submission.

If the noise is apparent you really have to clean it up.

why dont you try with Neat Image:

snurder:
I find myself that it is best to get the noise out in Raw stage. If you are using Photoshop, go to Detail in the raw stage - turn Sharpen all the way off and Color and Luma noise to 100%. Usually works for me.

If a little sharpening is needed for the detail, I use Filter>Other>High Pass, using a setting that will just begin to show detail (the layer will look all grey), then use either Overlay or Soft Light Blend Mode for that filtered layer. I usually use a layer mask with this High Pass layer, so that no artifacts are re-introduced into the sky and I can just reveal the detail where I need.

Just another option for you.

Lizard:
There is some noise in the blues , and Its alway easier to take care of the noise in the sky like this than the cloudy sky , cause running clouds trough noise reduction you loose details on the cloud and get artifacts. The way to handle that is to use layer mask on the noise reduction layer.
I have new monitor and I didn't have the time to calibrate it properly ,  but I'm almost sure that there is too much magentas here so your snow is kind of reddish.

Well anyway hope you don't mint that i tried to fix it a bit , I run it trough noise reduction , changed white balance a bit , a added some sharpness only to the rocks.
