Question

[foreveryoung]

can you answer the following question... The near a subject, the ? the distance needed between lens and film plane. would it be (greater, leaser, less important, or less consistent)

[RichardTaylor]

Greater - the lens will extend, either internally or externally (depends on the lens construction) , the closer you focus.

here's another that i got stuck on a piece of glass stained a dark red tens to produce what type of transmission? direct, diffuse, unpredictabe. or selective

Are you getting DPS to do your homework for you... ?

Just remember:

1/F1 + 1/F2 = 1/F

Second question I would assume they want "selective" as the answer as it will filter out certain wavelengths (colours)
