exception of macro photography, the main source of blur is not the fraction
of an inch that the camera moves around, but...

Guide number for off camera flash
Almost universally, these numbers are quoted for ISO100 -- your flash manual
should confirm that. ISO is the same as the now defunct ASA. So it still
works exactly the same way as you are used to:...

This sounds like a great idea, but are you willing to pay for it? If you
want to crop a 4:3 or 3:2 image out of the circle, you will be throwing away
about 40% of the precious sensor area. Or are...

Unfortunate for P&S
Can't speak for all P&S brands and models, but I found the optical
viewfinders that some of them provide almost totally useless: tiny, poor
optical quality, and above all, grossly mismatched to the...

Micro / Macro question?
Hi Doc,
Seems like your solution would be an 'industrial' type microscope, not the
ones used in medicine. These usually go to the magnification and the working
distances you need. The better ones...

Good economical choices for these purposes
I am finding it hard to understand why you want a 10:1 zoom for

5D is probably the only 'affordable' full frame (a sensor equal in size to
35mm film) DSLR on the market. Unless you 'need' a full frame camera, it's
probably not for you.
40D is a very impressive...

Better amplifiers only help to the point where their noise is no longer
