Hi, I'm having a problem with a long exposure shot I took. The sky is looking extremely pixelated when I throw it on any other screen other than my computer I'm editing from (1080P), viewing on social media. I am aware FB's recommendations of no more than 2048 pixels on the long edge, and even having tried exported accordingly, the sky is still pixelated. I've tried working with the defringe tools but the problem I'm having is it looks just fine editing through Lightroom and even in my Lightroom library, it is the exported file itself that looks messed up. I'm attaching pic 1, the quality at 80, no resizing; then pic 2, the quality at 100, resizing to 2048 pixels, though I know this forum is going to lower it even more, but maybe someone just seeing the pic will know what I'm talking about and how to help. I understand there's a lot going on when taking long exposure. The original I worked with is a RAW file, checked box for removal of chromatic aberration already. Thanks.
