>>7148442I'm finding that the larger the image, the better the result. When it downscales, a lot of artifacts become less noticeable. Also, the watermark becomes so small as to be almost not obnoxious.
This image is about the largest I could upload as an original file; there's supposed to be a 10 MB limit, but even an original of this at 8 MB was rejected until I downscaled the resolution.
