Adding black borders and white margins

- In this movie, we're gonna take our two-up octopus image…and we're gonna scale it down to Facebook size.…And we're gonna also add some black borders…and white margins just to help give…the images a little bit of breathing room.…So the first thing you wanna do before you add the borders,…you wanna go ahead and scale that image,…and that will help to ensure…that we have absolute black borders,…that we don't have any anti-aliasing around the edges.…So what I'm gonna do is, with this image selected,…I'll go up to the "Image" menu…and choose the "Image Size" command.…

And then, you wanna make sure…the "Resample" check-box is turned on.…You want the "Width" and "Height" values…to be locked into alignment with each other.…You wanna go ahead and change the "Interpolation" algorithm…from "Automatic", which is gonna sharpen the image…as it reduces it, which is a bad idea because,…if there's any further reduction later on down the line,…it's gonna get pretty gnarly.…What you want instead is: "Bicubic Smooth Gradients".…
