Using a phone for U.V style Photography

This is not true UV but an effect, the colours needed to try are blue and purple markers because they filter the light in a way that mimics a black light's effect. Random colours (like red or green) would block the necessary wavelengths and fail to produce the fluorescence. Additionally, you need at least two layers of tape, each colored specifically, to refine the filter.

@grok Is this really working?
