    Basic Lenses

    The classic approach to portraiture is to use a longer lens. A 210mm would probably be considered the 'standard' portrait focal length on 5x4. But the classic head-and-shoulders portrait look, with...

    Nodal point of lens

    You don't really need to know the nodal point of the lens, you just need to know the distance from the film plane to some reference on the lens, like the mounting flange. But in any case, I doubt...

    I used to dodge with filters when colour printing, to correct local areas of bad colour - like blue shadows for example. You need to use only camera quality (CC) gel filters below the lens. Normal...
