if what you’re cutting out is an extreme difference in color from its background (i.e. a picture of a person standing in front of an all white background), the magnetic lasso tool is absolutely amazing. If theres certain areas around the item you are cutting out and the background that overlap and are the same color, it can get tricky, but a little practice with the tool and cutting stuff out is no longer a problem.
I only offer this advice because i know that using the highlighter tool requires you to blow up your image to like 500% and use a tiny eraser to get unwanted BS out from around the edge of what you cut out… and that can be extremely tedious to say the least, and often comes out looking mediocre at best
