The example’s below are of the image used in the video one saved in Adobe RGB and the other saved in the sRGB colour space.
See the difference…. Hope this helps you get the most from your images on the web.
Note: This is for the web only, dont change your master images to sRGB as you will be deleting colour information that you cant get back. Someone described it as peeling an apple if you change an image to sRGB you cant unpeel it back to Adobe RGB… keep sRGB for web images only.
