how can i copyright photos I have taken?  And can I copyright multiple
images at once?  (i've heard of this technique but need details.)

Hello jonrahoi,

As stated at the bottom of this page, answers and comments provided on

I presume that you are interested in copyright in the United States. 
The U.S. Copyright Office has posted several pages on its website
concerning registration of visual arts materials.  The most concise
document I have found in response to both of your questions is:

"Registration of Photographs" (Fl-107, June 1999)
U.S. Copyright Office
http://www.copyright.gov/fls/fl107.html

For a longer explanation, you might consult sections on "Registration
Procedures," "Application Form," "Deposit Requirements," and
"Registration For Two Or More Works With One Application And Fee" on
this page:

"Copyright Registration for Works of the Visual Arts" (Circular 40,
revised December 2004)
U.S. Copyright Office
http://www.copyright.gov/circs/circ40.html

For related information, see:

"Copyright Registration of Visual Arts" (FL-115, June 1999)
U.S. Copyright Office

"Deposit Requirements for Registration of Claims to Copyright in
Visual Arts Material" (Circular 40a, revised December 2004)
U.S. Copyright Office
