herosa was correct, the aperture does NOT change, period. It is a property
of the lens, which has zero correlation with the sensor behind it, being CCD
/CMOS or film.
it's not complicated, just make sure you compare apple to apple first, then
start varying things. the apple here is the pixel size of the sensor.
what aperture decides (together with focus distance) is the light density
after the lens, a bigger sensor collects more light energy than a small

Long-Term Health Risks and Benefits Associated with Spay / Neuter in Dogs
Laura J. Sanborn, M.S.
May 14, 2007
Precis
At some point, most of us with an interest in dogs will have to consider
whether or not to spay / neuter our pet. Tradition holds that the benefits
of doing so at an early age outweigh the risks. Often, tradition holds sway
in the decision-making process even after countervailing evidence has

The existence of God using logical absolutes
This is an attempt to demonstrate the existence of God using logical

or human nature. They are not the product of the physical universe (space,
