Jewerly Loupe- You can get these for around 5-10 dollars.(I'm using a Bausch and Lomb 10x)
DSLR Camera
Tape
Tripod

Step 1: Setting It Up

This is fairly simple. Tape the Loupe to the camera. Boom! Now your ready to start shooting. Make sure you have manual focus on and get really close, like REALLY CLOSE. Then play around with your focus until it looks nice. The major flaw with this setup is that the depth of field is extremely shallow, so to make it a bit less shallow make sure you set you aperture to its highest. For example mine was f/36.

Step 2: Shoot Away!

Now get out there and take some pictures of stuff. Maybe take a close up of a bug or a detailed picture of a flower petal (unfortunately I couldn't since its winter). Have fun and hope you get some nice pictures.
