Re: convert looses EXIF orientation info

This has been fixed, even for Canon cameras, in ImageMagick 6.5.7, if not before.

Re: How to "Smart Sharpen," adaptive-sharpen not working

No Fred, I should try those scripts. Sharpedge has more of an effect on Lena's eyes (perhaps too much) and in some cases increases noise. Gaussianedge seems milder but still very noticeable. I am pleased with adaptive-sharpen, which is a big improvement over unsharp(mask). Adaptive seems to have wid...

Re: How to "Smart Sharpen," adaptive-sharpen not working

Anthony, thanks for your reply and (previously online) command examples! You are right that radius=0 works better than what I was using before. I experimented with all the one-place decimal numbers 0x1 and below. With 25% downsampling, -adaptive-sharpen 0x.6 seems to strike a nice balance between sh...

Re: How to "Smart Sharpen," adaptive-sharpen not working

Adaptive sharpening does seem to work in version 6.3.7 (build 06/04/09). Although many other numbers have an effect, I like 2x3 for 25% thumbnails: convert -filter Lanczos -resize 25% -adaptive-sharpen 2x3 -quality 95 -sampling-factor 2x1 ... A radius(?) higher than 2 looks oversharpened to me, and ...
