I have a light blue tint on my canopy. From inside the glider you can't
really tell there is any tint. It does not seem to impact any photography.
I were amber sunglasses and they are not a problem. However, it does
significantly reduce the heat load.

Another friend in my club also has a light blue tint canopy, however, his
sliding window is clear. You can really tell the difference in the heating
if you let the light from the window fall on your arm. It is significant.
