PHOTO: casual businessmen: This file contains artifacting when viewed at full size

I dint get the reason behind the rejection of this file, can anyone say which part of this image has error and how to overcome that, any technique to improve image quality.


rejection reason was: This file contains artifacting when viewed at full size.

/image 1 has artifacts over all the image. Look at the keyboard near the mouse - there is heavy speckling effects, where the plastic should have a continuous tone.  This may be due to heavy post-processing (or possibly in-camera processin) - In particular, avoid sharpening.


the second image is similar - look at the hair - very mushy and lacking detail.


Downsizing may help such images, but the main culprit is over-aggressive processing IMO. 


Check your camera settings and re-set if necessary.

edited to add - I just checked image 1 info - you used ISO 2500 - you should be aiming for ISO 100 as a default!!!

Both images are very noisy and full of artifacts, all over. They are well below the required standard, especially for indoors situations where total control of the lighting etc is possible.
Well processed, in focus images shot at 100 ISO will, for example, show clearly identifiable individual strands of hair in a head and shoulders portrait, not a vague mush.

Part of the problem is the ISO of 2500 and 2200 respectfully and the files indicate that the flash did fire with the Nikon D3100

Also, they aren't in focus, the white balance is off, the posing isn't really attractive, and the purple shirt is stained.

ok...got it, thank you for all your suggestion....thank you very much once again...
