saving .tif or .png renders look off when pasted over brighter backgrounds

Hello,

when I make a render I like to render the enviorment without the people and then the people in a extra render without the enviorment so I can edit them better.

But when I then put the people back in (with same lightning) they look like they are pasted in. Here are some test images, it works with white and black but once the background has some color they have a white line over the edge (see the gray one).
Is there anything I can do to deal with this?

    I was going to ask which format you were saving in, but I see it's in the title. please put the salient information in the body of the post, not just the title.

    Since you have ground shadows you obviously have at least Draw ground checked, which may account for the issue around the legs but I'm not sure why the arms are haloed only at intermediate values when you don't have strong rim lighting.

    Ok, I made it with draw ground off. Now it looks good.
    It seems like DAZ3D can't make proper .pngs when draw ground is on.
    I think I can work with that.... render it with the people in and then render it without the enviroment and then copy the people in on a top layer.

    That's very strange, I render almost exclusively with the background off to .png with draw ground on and I've never see that before.  I composite almost everything in photoshop.  You may want to try it with a slightly different set up or lighting rig and see if it still does that.

    Hmm I just tried it on my laptop with the standard HDRI and just the dome draw off, nothing else and it worked.
    It's a fresh DAZ3D install on my laptop too...
    Very weird.

    Must be a setting off somewhere.  Of course tracking it down could be difficult.  You may sit down with the laptop and pc side by sid and go through each lighting tab and render tab and see if they all match

    I'm still having this issue. If anyone would give a solution it would be appreciated.

    Here I have the basic G3F on a clean install with the default render settings (The ruins).
    I can't be the only one with this issue if this happens on a newly installed DAZ3D with everything set to default.

    Edit: Same issue with GIMP, so it isn't PS related.

    This may not be the solution you are looking for but you can remove the 'edge' in PS (or gimp but I do not know that program) pretty easily. 

    One method:

    with the image on its own layer (and your desired background below but hidden so you can more easily see what you are doing) cntrl-click on the figure layer thumbnail in the layers pallette to select all the non-transparent pixels in the layer.

    Go to Select/Modify/Contract (top menu)

    Set it to 1 pixel, hit ok.

    Hit cntrl-J to duplicate your selection to a new layer (so you dont edit the original in case you want togo back).

    Hide the original figure layer.

    Unhide the background, see if theres still a fringe. If so, delete the new layer, go back and reselect the pixels in the layer, redo the selection/modify/contract with 2 pixels, or 3...

    Thanks. This seems to work. I'm still wondering why this is happing though. I wrote a support ticket, maybe DAZ3D can help.
