Today I looked through my working directory and found this HDR I did some month ago. I have a bunch of nearly finished pictures because I always have the feeling that something is missing :).
Anyway as I spotted this processed picture of Akihabara I thought: "Wow it looks like a scene of Blade Runner" (amazing movie by the way). I was toying with the Retinex-Filter of Gimp to get some texture on the walls. But with the texture there comes noise. And noise-reduction kills the texture. A vicious circle. At some point I accepted the noise and trimmed all to this dirty mood.
That's how it works. Making a HDR is always surprising as you never really know whats coming out in the end. (at least I never know :D)
