Well, show me an image then you think has no noise, and I will check it.

The other one of the dome building I posted with the chinese pic. That is Raw with 125 iso.

I looked at the Dome picture (downloaded full size).  There's noise in the sky and the overall image isn't sharp.  It's also LCV so as others have suggested the inspectors will look for any opportunity to reject.  Sorry.

The Chinese objects picture is also LCV and should in any case be rejected for copyright.

It looks soft to me, in other words not tack sharp.  There's sensor noise all over the sky, more so in the darker areas of course.  You can get rid of that noise by selecting the blue channel and applying noise reduction or a gaussian blur.

LCV means Low Commercial Value.  This is just a snapshot of some uninteresting dome somewhere.  There's no copyspace - the dome is just sitting there slap bang in the middle of the picture.  Nothing to identify what it is or where it is.  Very unlikely to sell, hence LCV.

To be fair, if this was a HCV pic, it might get accepted despite the technical shortcomings (a designer can always get rid of the noise and/or sharpen it).

If you want a further opinion, perhaps JSnover will have a look - she's the photoshop and image expert around here.

If you want to produce lots of highly saleable and technically good stock photos, get rid of your small sensor camera and buy one that has at least an APS-C sensor.  I suspect that your Sony is going to be a source of tremendous frustration for stock photography.  That doesn't mean it's not a good camera for general use.  Standards have gone up, particularly at Shutterstock, with thousands of high quality photos being submitted every day.  The inspectors don't need to accept second best, and they'll just reject unless the picture is unique or has seriously high commercial value.

Example?

Ok but a little dubious of sharing for fear of image theft from browsers who don't belong to this forum.

Herg, I have checked the image at 100% and I have to agree with the reviewer, there seems to be pixelation going on, which looks like its because of the small censor capacity.

This is a good read http://www.gizmag.com/camera-sensor-size-guide/26684/



If you check at 100% you will see the noise / pixelation clearly

The sensor is fine at lower ISO, but the Chinese stuff image was taken at ISO1250!! What do you expect?
