how to get luminance false color images

Hi Violeta,

Unfortunately, the command-line tools in Radiance are difficult to use if you are not used to them. I am not sure what options Axel Jacobs uses for WebHDR, but you can try the following:

  falsecolor -s auto -i input.hdr | ra_tiff - falsec.tif

This will result in a linear luminance scale. If you want a log scale with 1000:1 range (10^3:1), use:

  falsecolor -log 3 -s auto -i input.hdr | ra_tiff - falsecl.tif

If you have a Mac, you can download Photosphere, which has a more familiar application GUI from:

Best,

Hi.
I've been using the R-Y-O demo (http://www.jaloxa.eu/webhdr/demo.shtml\) to get luminance false color images, but it says that the program is currently down.
I know there is a way to get those images from Radiance. I´ve been looking through the documentation posted on the web site but its been really difficult for me to understand.
I was wondering if there's an easier way to do it, since it was really easy to do it on R-Y-O.

Thank you very much
