I just discover that some of my isolation whit the pen tool was correct just before saving them.

But after saving them at the maximum quality ... I open the saved file reselect the 255 background (select tool always at 0) and then I see several areas who aren't properly isolated.

I don't know what to do...I'm a bit lost on what do this. Maybe it's because it's a Jpeg file and the quality decline after the save.

I also think that when I select the size in the saving option from 28.8 to 56.6 the new infos don't have the time to load. But I really don't know which way to look first?

"I don't think JPEG compression would add artifacts in pure white regions. "

It does. Little ghosts appear around the isolated object, close to its boundary. Setting threshold to 1 or 2 gets rid of them (when selecting 255,255,255) color. I guess this is what some of the reviewers are picking as "bad isolation" - which is incorrect.

Vonkara,

I had this problem in one rejection, though I make sure my whites are really whites in TIFF, they still get some type of

See this thread with the previous discussion (black background in my case):

It is odd for a rejection as it seems inherent to JPEG compression that this happens (much to my surprise by then).  Indeed, I checked other approved isolations and they all have this.

I didn't resubmit because we were already so close to New Years.  I should open a ticket though.  I sold some 2007 images late in the year.

I also find that including the path is at least the same as having a perfect isolation. It's becoming a bit absurd.

Another thing who become absurd is when I shoot macro. While the magnification is increasing, the focus range is decreasing and that's normal. I can increase the f stop, but that's play more and more whit the sharpness pass f/11 or f/13. Then it's the "to much of the image is out of focus".

But I honestly think that this is the macro world. It's difficult sometime to choose between dept of field and sharpness.?.

Yap, I posted about it here and on the SS forum. I had examples but can't show them any more because I was banned on Flickr. Basically, it's a jpg artifact. Select the white with the Magic Wand Tool: tolerance 0, ant-alias and contiguous off. On the TIF you will see a nice isolation.

Save it as JPG maximal quality. Load that JPG and do the same. You will see small non-white (254,255,254 or so) dithers around the edge.

On SS I was advised to do clipping paths.

OK, I'm quite a super newbie whit clipping path. I have the oldest photoshop dinosaur here whit the 6.0 version. I wonder to know exactly what is the clipping path? When I use the pen tool and close my selection, I go in layer.

Then I click on "path" where my selection is showing. Do that is the clipping path, because I can easily move my selection? But it's not showing the word clipping nowhere in 6.0? I'm quite lost at this point as I never at this time being able to see CS2 or 3 and compare. Any help would be appreciated.
