    Re: Fumbling towards a correct exposure for Dry Plates

    A lot of good stuff here. Thanks everyone.

    Now another few questions:

    I understand that the spectral response is deep in the blue end, perhaps even near Ultra Violet. If that is so, is any exposure compensation requirted to account for that? If a scene is metered for ISO 100 film (and I make an exposure on that film) , then adjust for the nominal ISSO 1 speed of the dry plate , as discussed above,. . .is any further adjustment needed for the loss of half the spectrum?

    I assume that best exposures will come at high sun angles (say, 10AM to 3PM), as the "golden hour" just at sun-up and sun-set will be strong in the red end.

    Lenses to be used are "modern" , mid-1990s vintage from Rodenstock, Fuji and Nikon. Can I assume that these are corrected enough to avoid a blue shift in focus (getting really modern "APO" lenses is off the table).

    There are only three types of mounting flanges; too big, too small and wrong thread!
