A friend of mine asked for a print of the GGB tower:

So I've been working on one. One thing I tried when dealing with getting this image into gamut was using Photoshop's select by color range to select out-of-gamut colors. But after making a proof print last night, I found a lot of areas that looked like crap because the selection hadn't been feathered at all, resulting in lots of ugly gnarly edges.

Sharpening's kind of proving to be a hassle, too - ugly artifacts in both some of the fine detail and the smooth tones in this image. Trying to fix that noise is leading to some posterization, too. So, yet more work ahead.
