Imported screen shots look great ... until previewed...
I'm using SL3, taking screen shots of an old "green screen" system with SnagIt, and saving as .png. I've been trying to capture them at the size I will be showing them in SL3, to avoid re-sizing. Then I take them into Photoshop and adjust the exposure and hit them with Unsharp Mask to really brithen them up and get them crisp.
When I put them into my slide, they look OK, but when I go to preview or publish, they suddenly look like .jpgs with major artifacting or dithering, all muddy, and it's difficult to read the text.
I've set the image quality in the Publish window to 100%, with no discernible results.
Advice? Thank you! :)
