Yesterday I took a night shot of Hooghly Bridge with D5100, and it was cool :) I resized down the image to 2048*1356 px using Photoshop CS5 [default settings] and uploaded the image to Facebook. And it was ugly, the dark places were full of noise.

How to guess the proper settings for image resizing [except guessing] so Facebook modifies the picture as little as possible !

This questing is related to Image processing also, not just with the FB ! –  Sourav Jul 14 '13 at 16:12
    
FB does a lot of post-processing to any image. If you're uploading to an album, you can select to do a "high quality" upload. –  ncdownpat Jul 15 '13 at 0:56
