Mineral lighting how your minerals, your lights, and your eyes all interact
While anyone can get light on a rock, getting it to look right is hard—getting it to look right for all of your specimens tends to make it a frustrating endeavor for many mineral collectors.
The reason for this difficulty is that multiple factors affect the optimal viewing of a mineral, of which most people only understand a few. Your lights, your minerals, and your eyes all interact to produce a combination of effects that impact your viewing pleasure… or displeasure. Properly lighting your minerals is a surprisingly difficult task that we seek to simplify.
We start with the fundamental part of seeing. In other words, how the human eye works—at least as far as viewing minerals is concerned. What catches your eye? What allows your eye to see your minerals better? How are colors perceived?
After that, we discuss the various types of lighting available: halogens, fluorescent bulbs, and the popular “white light” light-emitting diodes (LEDs). What most don’t understand is that most “white lights” may fool your eye and appear white, but they are not. We demystify this assumption and explain how different lighting types affect the color and look of your minerals.
Using the information on lighting and how the eye works, we then provide information on how to light your minerals, what kind of lights to order, and how much light should you put on your minerals. This comes with Tony’s three big rules on mineral lighting, which will aid you in understanding the things to look out for when designing and installing your own lighting.
