A photo is made of three channels: red, green, and blue, that when combined form a color photo. For this orange and teal look, we’re going to start by converting from three channels to two channels. To do this, go to the adjustments panel and add a channel mixer adjustment layer. If you don’t see this panel, you can open it by going to “window”, and then “adjustments”. Here in the channel mixer properties, go to the blue channel and set the green to 100% and the blue to zero.
