I notice that the colors/saturation of my edited photos on Lightroom 3 looks MUCH more different than when I upload them onto Flickr and 500px.
It looks much less saturated on online hosting websites. I edit my photos according to how they look in LR3. After I Export them and open it up with Preview (I use a 13" Macbook Pro), the colors still look the same.
Does my Macbook or LR3 have some color problems, or is Flickr and 500px really desaturating my photos? Which colors should I follow? I don't really look at my pictures from other computers, so I don't know how others view my pictures.
