Re: How to draw with tranparent color / how draw erasures?

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!

Re: Develop Canon RAW images into mutliple tiffs

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!

Re: Develop Canon RAW images into mutliple tiffs

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

Develop Canon RAW images into mutliple tiffs

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

Re: Font warning on montage command

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

Re: Conversion of CR2 files is VERY slow

Thanks for your suggestion, Fred

Code: Select all

convert -version
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

Code: Select all

ufraw-batch
is the culprit?

Thanks, Walter

Conversion of CR2 files is VERY slow

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 mi...
