I'm getting crazy with some rejections on Shutter Stock because of noise on the image.
Are you able to tell what type of noise I have on this image so I can try to avoid it?

This is the original image taken with my camera which is not a DSLR. But I don't know if the noise is caused by is sensor dust, poor sensor, poor lighting, or maybe the image stabilization software on the camera that does not work well... I actually never noticed there was noise on my pictures, but after the rejections, I've analyzed carefully the image at 100% view and noticed noise, ie. on the transition from the blue to the skin color, near his left shoulders... There are noise too on many parts of his skin, they are like white spots...

Any advices are very welcome! Thanks in advance!

picture looks sharp, well exposed, focused and i can't see any noticible noise, so i dunno...
can you post 100% crops of the areas you think have some noise (like the skin, darker areas and the transitions between contrasting image areas)?

I can see some chroma noise in the shadows under the chin.. but not enough to cause any printing disability.

Are you sure they werent talking about a noisy background instead? :-)

I am not too sure if critics at these stock websites spend enough time per picture. Usually, if they find 2-3 in a lot unacceptable, they tend to flag teh rest the same way too.

I also see a little noise in the shadows under the chin, but really, it looks pretty darn good to me. I think the stock agencies just use that as one of their general purpose reasons to offer if they don't think a shot may sell. They can afford to be picky, but they have to give you a reason that is better than "we don't want it", so that is one of them. Everybody that tries to do stock gets those rejectiosn that make little sense. My second highest scoring shot on this site (a 6.5 score) was rejected by Istockphoto for "no clear focal point".

Thanks for the comment, you can look at the full size image here.

The chroma noise on the shadows is what I see mostly. Take a look on the full size and let me know...

Regarding these sites, I'm starting to think they give false justifications when they judge the photo is not good to sell...

At 100%, I see quite a bit of luminance noise in the shadows (wrinkles, lips, teeth). The chroma noise is mostly proliferated under chin. It's otherwise negligible.

I see it, too, at full size......but that is NOT print size and is decidedly splitting hairs.

Can any of you tell me how to avoid the noise present on this image?
or this is something related to the sensor on my camera?

Personally, I don't obsess about a little luminance noise. It is, however, a pet peeve for those who find it easier to judge "technical quality" as some sort of standard than to recognize a good shot.

Some cameras produce more/less noise than others. Full-frame sensor DSLRs are your best bet. The noise in the image you posted, however, can be easily removed by running the Reduce Noise filter or using one of several applications or PS plug-ins to do the same job.

Yep! Lightroom is great for that!
