This may be the wrong place to ask -- I don't think many of my Nelsonfoto friends are as into "noising up" pictures as I am from time to time. I do it sometimes to make an image into what I want, adding Gaussian noise to areas of the photograph that may be distracting, leaving central subjects unnoised. Sometimes I use noise to hide gaffes or joins, or whatever. All in the interest of a final image.
Sometimes I post such selectively noised pictures to Facebook and discover that -- unlike other sites like Flickr or Nelsonfoto -- something in the way Facebook displays photos increases tiny levels of noise into sand-blasted sections. What may be unnoticeable noise in what I send to Facebook becomes really over-the-top abrasion both in photo "albums" and in mail messages.
I suppose I could do trial and error to see what the threshhold of noise would be for each photo I post to Facebook, but it would be nice to know what Facebook's problem is and avoid it altogether. Uhh, without having to avoid Facebook itself (that's a different story altogether...).
Has anyone else had this problem with Facebook?
