Sunlight on a mixed media on steel picture, by .dappy on Feb 24, 2013 15:11:09 GMT 1, Without a covering, light will always 'fade' colours even light-fast colours. But will anybody notice it - prob not, especially if the light is even across the face of it, ie it only gets direct sunlight across part of the image most of the time eg part of it is always in shadow, then over time you may see a difference. Glass by itself will not offer protection you will need UV or museum type (or perspex for such a large piece if it is the 1m x .8m piece I am thinking of). if you have direct sunlight, I might be more worried with the metal expanding due to heat and bits of the mixed media cracking/falling off!

I have a large piece on metal framed and behind museum glass 'by' a window - no probs - but won't let the missus turn on the fire!
