Hi All


I have just had a noise rejection on this image


file_thumbview_approve 


submited http://a6.vox.com/6a00e398be844500040100a8022e46000e-pi


Raw http://a5.vox.com/6a00e398be8445000400fa96a1276d0002-pi


The black areas look fine to me and that is normally where noise is hiding.  So maybe it is the skin texture, I have included the raw file as well to compare against. 


As for processing, I have applied levels to help get the background white, selective sharpening on the eyes, and capture sharpening to take out the inherent softness of a raw file. I also cropped and downsized as the original had too much white space to be left as an XL.


Thanks in advance Jo

I think it may be just oversharpened in my opinion.

You have way over-sharpened this - most RAW converters have defaults for "capture sharpening" that are too aggressive. Take a look at this

I used a high pass sharpening layer masked so that only the eyes, eyebrows lips and teeth were sharpened (and the white shapes on the front of the scarf if you like).


The noise seems most noticeable in the shadows of the fleece vest, so I used Noise Ninja (masked) to remove that. The curves adjustment layer got the background right behind her neck white and then a soft edged layer mask cut out the rest - if you get the whole backgorund white with one adjustment, some of the subject becomes too bright.


See what you think

Thanks guys.  I used Capture NX2 to develop the raw (NEF) file. Sharpening is switched off in the camera and on capture too.  I use multiple level adjustments not just one on the background and brush out the foreground (a capture version of a masked adjustment layer).  I guess my final high pass sharpening was too much. I'll go back to the tiff.

I usually make a sharpening or high pass step, find something (like an eye) and get it dialed in right, then use selection control points and the selection brush to add small amounts of enhancement just where I want them. Each point and the brush in CNX2 can have the opacity adjusted as well as the radius or feathering. The is no enhancement applied to the image as a whole, only the specific areas. Is that what you are doing Jo?

I don't think this was rejected for noise, but for artifacting. Look at the left side of the scarf in her shoulder area, where the highlight is VERY "hot" with some artifacts.  This is what happens when the levels are overdone.


Just my opinion.
