The following images were arrived at by taking a 3-shot handheld bracket with the GR and aligning and tonemapping it in LuminanceHDR, then manipulating levels & curves in Showfoto (the Digikam image editor) - as was the one B/W conversion - while noise-removal plus final sharpening was done in NeatImage for Linux (the only bit of non-free software I use/own). The thumbnail creation with dark edge and watermark name in the lower right is done through a bash script that uses ImageMagick. {} Old Amersham by newmikey, on Flickr {} Tube station waiting room by newmikey, on Flickr {} Tube station waiting room by newmikey, on Flickr
Thumbs up on the images and the processing. I'm a GR owner and I've been planning to someday check out HDR, stacking, stitching etc. to see what I can come up with. This is good inspiration, thank you
