Light in Photography - LIGHTING - FLASH
lighting for close up photography
it can be useful to use an off camera flash to illuminate small items
like flowers and insects etc. As we move closer to an object we tend
to get less depth of field, so using the illumination of the flash
not only stops moving subjects but allows us to use a smaller aperture.
If we use
a standard lens on the camera ( say a 50mm on a 35mm DSLR) with extension
tubes or a bellows unit we might find that the lens is physically
so close to the subject it blocks out the light. By using a longer
focal length ( a telephoto say 100mm lens we find to fill the subject
in the viewfinder the camera position is now moved back considerably.
This allows light to fall uninhibited on the subject. We can also
augment this with a flash light.
