I captured a low key RAW photo with my Nikon D5100. I processed it using Lightroom, exported it as a JPG and then set it as my Facebook profile picture. Despite the initial JPG looking good, the result in Facebook was horrendous to say the least. I figured it might have been due to Facebook's image compression, so I decided to upload it to Flickr to compare. Again, the image quality when uploaded to Flickr is terrible.
I started thinking that maybe I had overprocessed the image, so I tried exporting the RAW to JPG without applying any changes (except for cropping). The issue persists.
Below are the RAW, JPG and a link to the JPG as it appears in Flickr. Can anyone explain to me what is happening here? And how I could possibly avoid the undesirable results if I intend to share my photo on Flickr?
