wetplate and uv sensitivity
General knowledge seems to say that wetplate/collodion is very sensitive to UV light and not to visible light.
However, I see very sharp wetplate photographs done with very fast lenses. These lenses are apparentlhy not corrected to focus uv light at the same plane as visible light.
My question: why are the wetplates not blurred from being out of focus due to the uv focus shift?
The sharpness is leading me to believe that wetplate is not so sensitive to UV as it is much much more to blue and blue only.
My experience is only in dryfilm/cogeletain, no wetplate/collodion, so please enlighten me as to what is REALLY going on here.
