I’m currently in the middle of making a review for a product. Being me, I thought it would be fun to make my own professional shots with a little handiwork and Photoshop. It’s really nice to do things with your own hands for once, so I suggest you try it as well.
I would do a step-by-step tutorial, but I suck at that stuff. So just watch this section from Buzzfeed. You don’t need to get a clamp light or an X-Acto knife thingy, just get your everyday fluorescent light/torch and a box knife.
Start from 0:51 seconds in and then enjoy.
