This is a repost of Episode 84 – there seem to be some feed problems. there is no need for download if you have seen 84 already.
This week I start with a short introduction into autostereoscopic images, see two posts below. Then I cover the GEGL operation “c2g”, which converts acouloured image into a monochrome image with a lot of noise or other other effects. It’s a “try out” thing – up to now I have not found documentation. Perhaps one has to look into the source. Be warned – some parameters can kill the program.
Then Joseph tells us. how easy it is to make “HDR” images with QTPFSGUI. It’s not as complicated as I feared. I’ll try it soon myself. The website Joseph pointed me to is here.

A warm welcome for a continued tutorial about QTPSF!!!

Thanks, I have included the link in the post above.
… and now, after I have simply edited the posting, all thre PodPress links are mp3 again and will not show up in the feed……
Although I have not got any images of the same scene taken at different exposures I have selected from, amongst my images, a landscape and simulated different exposures. I have then combined these to practice with Qtpfsgui with most interesting results. Just an idea but worth trying.
That is a valid way too, especially with RAW images.
I had a little bit deeper look at c2g, played with it and published my experiences here: http://blog.wbou.de/index.php/2009/08/04/black-and-white-conversion-with-gegls-c2g-color2gray-in-gimp/
