This page used to contain a complex twisty-turny troubleshooting workflow for figuring out why photos looked different from Photoshop when you posted them on Facebook.
I’m very pleased to say that in 2020, both Facebook and the internet browsing programs have got their acts together and standardised colour rendition, so I’ve removed the troubleshooter. Facebook photos almost always match their Photoshop master files now, as long as you’re viewing both on the same screen! Viewing your Facebook photos on a phone or tablet is still a painful lottery, because those screens are all different. Please try not to get hung up on how members of the public are viewing your photos, because you can’t control that. You can only control colour at your end, and you do that by having correct monitor calibration.
If you happen to be one of the unlucky people whose Facebook photos don’t match your Photoshop photos, please visit me at Ask Damien so I can help you troubleshoot the problem.
