How to Make a DIY Digital Pinhole Camera with a Body Cap

I was interested in seeing how well a pinhole would work on a small sensor (APS-C) DSLR so I decided to give it a try. All I needed to do was to drill a hole in the spare body cap, darken a piece of aluminum foil with a permanent marker, punch a small hole in it, and then tape it to the front of the body cap.

How to Capture Ultraviolet-Induced Fluorescence (UVIF) Photos

Ultraviolet-induced fluorescence (UVIF) occurs when molecules in an object are excited (energized) by high-energy ultraviolet wavelengths (from our UV flashlight) and as a result, emit longer wavelengths in the visible portion of the spectrum (red, green, and blue). These emitted longer wavelengths are what we are photographing.
