I'm a little confused as to why the image looks pin sharp on my Macbook Pro screen (yes I know it's Retina etc.), but when it's uploaded to JP in the upload queue it doesn't look sharp at all. What am I missing or doing wrong? Hopefully someone editing on a Retina display can shed some light on this.
These following examples are quick photos taken of my screen..
