New to Istock so I hope I am posting in the right section.


I have just recently had some problems with strange artifacts on my isolations.  I have been using the same process for a while and never had this before:  My workflow is, open the raw file in photoshop, make any adjustments, then do my work with a pen tool and save as psd.  then when done save as jpg (12) .. i was getting some rejections for poor isolation and noticed that i was getting some artifacts. 


looks like this (enlarged a bit to show the detail) artifacts%202


 


it's all the spotty things on the white area..  Not sure what i'm doing wrong.  Going crazy trying to figure this out!  I am havng the same problem in both cs6 and cs5 .. tried with photos shot with different cameras.  The only thing maybe that i have changed was i added some ram to my pc a couple of weeks ago.


Any advice or recommendations greatly appreciated ..

I think it will help a bit to understand a bit more:

What is this a photo of - what's the crop showing? Full sized watermarked photo will be much better to share to determine lighting conditions, etc.

What are your lighting conditions, etc.?

Camera make and model *your exif is showing dmkIII but I think that the problem sounds weird for this brand new camera

They are really sharp and solid lines that you are sharing so I'm wondering if the selection tools you are choosing are to blame?

those are 'regular' and unavoidable JPG compression artifacts. You are best off to save clipping path in JPG so buyer can re-isolate quickly. iStock inspectors do not reject those kind of artifacts so you may be looking in a wrong place.

If they weren't there in PSD but visible in JPG file only, it seems they are from JPG compression. But since you are saving at high quality setting (12) I wonder if those were there in PSD. How was this sample saved? Is it also saved at highest setting?

@pink .. sorry if i didn't explain too well.. it's a crop of an isolation i did and then i increased the curves to check if it was clean.


@slobo ..  ok.. thanks.  i will look for any other oddities besides the compression and see if it passes.


@kativ .. yes, they werent' visible in psd only in jpg.  this sample was saved at jpg (12) as well.


 


it just seems i have never noticed it before.  I will go over with a fine toothed comb for any strays and try to resubmit.
