Trying to get those pixel perfect macro shots on a budget? Build your own DIY low cost ring of light with a [NeoPixel Ring][1] and [Trinket][2], Adafruit tiny arduino micro controller. The color and brightness of the LEDs can be programmed to color or pattern!
Using the [24x NeoPixel ring][1] as a light ring is a great way to enhance macro-photography. A ring of light provides a spot-light effect, removing shadows caused by the camera getting in front of the subject. In our test shots above the [NeoPixel Ring][1] projects a ring of light inside the eye.
