Saving documents

- [Instructor] As we work through the exercises…in this training course,…we'll need to learn how to save our working files,…or our edited files.…First, we need to make a few changes to our image,…so I'll quickly choose Layer, and then duplicate this layer.…I'll click OK, and we can see in the Layers panel…I now have two copies of this layer.…This top copy I wanna make a change to,…so I'll select Image, and then Adjustments.…And then, I'll choose the Gradient Map adjustment.…

That's rather fun!…If we click in the downward-pointing arrow here,…I'll choose this purple to orange gradient and apply that,…and then to get these two layers to blend together,…I'm actually gonna changed what's called the blend mode.…So where it says normal, I'll click on that,…and change that to multiply.…Once we've finished all of our image editing,…I don't want to save over my original file,…and I wanna save this as either…a .psd file or as a .tiff file,…so that I can retain the layers in case I want to…come back and work on them later.…
