at first I saw it white/gold .. but then it became blue/black and then my girlfriend came, and we were talking about the dress (ATM she hadn't ever seen it) and to my surprise she starts seen it as white/glod!!! -- and I was (puzzled) seeing it clearly blue/black after some 2 o 3 minutes, she started seeing it was starting to _change_ .. and then boom! all she sees is a black/blue dress, and also she notes that the image has background, before she was only seeing the dress and backlight .. before she could not recognize anything in the background as there was too much lightning is this something the brain could "fix" and after that period, you cannot unsee?
