Ok, so it's precision loss. If you can find some good images at low zoom (magnification) levels, they should look much better. The "Mag" number in the upper right corner of the window shows the magnification. The second image in the Quickman.log file has a low Mag of 2835, which should be fine at almost any size. The threshold for quality loss will vary (depends on the output size...

One other tip: it's best to stay at low zoom levels when making very large images, to avoid precision loss. Maybe this is what you're seeing. When precision loss happens the "pixels" get larger and become oddly shaped, and the image gets generally mangled. One day I might try to add arbitrary precision support to Quickman, but that's a big project...

A 3 x 3 foot image at 300 dpi would be 10800 x 10800. You could try generating the image at 4x resolution (43200 x 43200), then load it into Photoshop and use some of its tools to smooth it. The noise reduction, dust and scratch, and/or blur filters would probably work well since the fine details (which you don't want) are basically noise. After smoothing, resize the image back to 10800 x...

You could upload your images to a website like flickr, then post a link to them here...
