[jmvw]'s idea (Tan Tattoo - see link) reminded me of this one - don't know whether to put it as Fashion:Tattoo:Temporary or Fashion:Tanning, but here it is:
Take a black and white medium or large format negative (or digitally print onto acetate if you must) and sellotape to a body part. Lie in sun
until golden brown - baste with suncream as necessary and season to taste (probably summer).
This should produce a positive with tones ranging from as white as you started to as brown as you might normally tan to, and all those in between.

I'd suggest linking to the inspiring Idea instead of lauding it inline to the post. Seems a good enough category. |

Oh yeah, finally another use for my negatives. The 35mmm is not going to be much use, but the 2 1/4 would work okay. |
|
| |
Or could I use a lens fixture and magnify it and lay very still under it? |
|
| |
very clever - I wonder what the resolution of skin is? |
|
| |
If UV is what gives you a tan, then would it be filtered by
both the black and clear parts of the negative? |
|
| |
Correct me if I'm wrong, but I think you could make
one where you don't know what the picture is until
you tan with it. I believe you could make the uv
attenuated parts invisible. |

Unfortunately most materials you could make these negatives from block UV-b, the suntanning part of UV. As [Ling] alluded to. |

Tried this with aluminium foil for the masking, back in the 1970's, however, as it was in the British summer, difficult to see if it had worked or not. |

I thought I'd ask some knowledgeable people about UV transmittance[link] |

Transmittance of silver-iodide and cellulose ? |
