Thanks snibgo. Will try it out.

From the script I understand that you create the doughnut in b/w and then use the black parts as a "stamp" to put on a empty (=transparent) background. Very clever!

I want create a blue doughnut on transparent background. So far I have a circle on trans[arenty background with a white middle: convert -size 1001x1001 xc:white -alpha transparent transparent.png convert transparent.png -fill "#2244aa" -stroke "#2244aa" -draw "circle 500,500 1,500" circle.png ...

Thanks a lot snibgo! This is very detailed and points me exactly in the direction I want to go!

I really like idea of faking the ISO metadata to trick the subsequent tonemapping tool. I'll try it out with Photomatix!

Ups, I wasn't detailed enough: I know that I cannot use the tiffs for a real HDR, but what I want to get tiffs from the raw file with +-0EV, +1EV and -1EV using all the information available in the raw file, so that I can put them through the same HDR process

What is the best way to convert a Canon raw file (CR2) into 2 or 3 differently exposed tiffs for pseudo-HDR/tonmapping?

So, from *one* RAW file I want to get a tiff with +-0EV, +1EV and -1EV. How can I do this via ImageMagick and it raw reader dcraw.

Many thanks, Walter

Aaah, I have to reinstall IM after installing GS? Do I have to compile it for this? (I use the pre-compiled "bottle" from brew for OS X.)

Thx, Walter

Thanks Fred. Makes sense. But how can I make the warning go away? I now have installed ghostscript , the folwing message still occures: montage: delegate library support not built-in `/usr/local/share/ghostscript/fonts/n019003l.pfb' (Freetype) @ warning/annotate.c/RenderFreetype/1526. freetype is ...

I'm creating an image montage with the follwoing command: montage -monitor pic1.tiff pic2.tiff -geometry 1000x1000+20+20 -tile 1x2 -background white out.tiff It works, but I get these strange warnings: montage: delegate library support not built-in `/usr/local/share/ghostscript/fonts/n019003l.pfb ...

Thanks for your suggestion, Fred
does indeed list the feature OpenMP. (This is actually the only listed feature.)

Not sure how to compile IM through MacPorts though. Don't you think is the culprit?

Thanks, Walter

Hi there I use ImageMagick to compare the image content of some CR2 (Canon RAW) files. This is VERY slow. E.g. on a MacBook (2.5 GHz Core 2 Duo with SSD) it takes around 2 minutes! Some fiddeling revealed: The conversion is the slow part. For example convert CR2:IMG_1234.CR2 IMG_1234.tiff takes a ...
