Artifacts left after using background erase tool in X6-64bit

[philcarnahan]

I recently tried using the background eraser tool to remove a sky so I could use a different sky from the layer below. All went well, but when I was done I had a lot of pixel size white artifacts showing. They are not in the sky only layer. Further when I click on many of them, they disappear as long as the mouse is held down, then return as soon as the mouse is released. Others just don't change. The effect is the new sky has spots of "snow" that can't be erased. I've tried noise reduction on both layers with no change. The original sky being erased was a uniform light gray (boring). Replacement is an orange sunset sky with clouds. Just wondered if anyone had encountered this and found a fix. Win 7/64 bit with PSP-X6/64bit. ps: I did run Topaz Labs Detail on this image before the background erase. Thanks for comments and feedback!

It could be caused by any of the many Background Eraser Tool options (F4). Pixels outside the boundaries/tolerance won't be erased.
Read the Help to find out what each of the options does.

Assuming that the edges between the sky and the horizon have been succesfully erased, you could erase the scattered pixels with the normal Eraser tool, or select the sky with the freehand selection tool and press Delete. There are probably more ways, but just give it a try.

If that doesn't work, come back and tell us if you're working on multiple layers etc. and the Tool options settings.

Thanks for the suggestions. I had pretty much explored the tool options and none had any effect. However switching to the eraser tool worked. A little more touchy since it is not edge sensitive, but I was 95% done so it didn't take too long to clean it up (if an hour is not much).

You need to start using Mask Layers. Please see http://forum.corel.com/EN/viewtopic.php ... 79#p239079

Thanks for that suggestion. I looked at your tutorial and it obviously works well. I admit I'm struggling with using layers but am at a point I have to conquer it to improve. Many hours in front of computer coming.....

Thanks again
