Flash model cameras are definitely preferred for underwater photography to illuminate the colors. The AquaShot 3 will ONLY accept flash model cameras.

Before using any unfamiliar studio strobe or other non-dedicated flash unit with an EOS camera, we STRONGLY recommend that you determine its trigger circuit voltage. Excessive trigger circuit voltage can damage the shutter units and X-contacts of most modern 35mm SLR cameras. Please be aware of the following information: Trigger Circuit Voltage: The "trigger circuit" is the part of any electronic flash that detects the X-sync signal from the camera and then fires the flash.

The FL-50 flash can be connected with the E-300 camera through flash power grip: FP-1 and flash cable: FL-CB05. Only Auto and Manual mode can be set in the concurrent use of FL-40 and the built-in flash. (For their specification design, E-300 and FL-40 can not communicate in TTL Auto and R-TTL Auto modes.)

That depends. Many third party lensmakers - Tamron, Sigma and Tokina being the big three - manufacture lenses specifically designed to fit Canon EOS cameras. These lenses will, of course, work fine with EOS cameras. The main caveat is the compatibility with the electronics detailed above. However, if you have a third-party lens which does not physically fit onto your EOS camera then you can obviously assume that the lens will not work with EOS cameras.

Why don't I get the chance to make a fancy vTag with graphics and text? I see other people with them.

In the Washington area, you may bring equipment. All bags and carrying cases must be left in lockers outside of the research room. Flatbed scanners without sheet feeders are allowed. When you are using a scanner, you must show it to the research room staff and receive special instructions. More information on using scanners. Outside the Washington, DC, area contact Regional Records Services Facilities and Presidential Libraries directly for their policies on equipment.

The number of cameras we use at a wedding depends on the package you select. Three of our four packages include two cameras at the ceremony. We encourage clients to select one of these packages for several reasons: Multiple cameras give us the opportunity to capture multiple things at your ceremony or reception simultaneously, and

Thyristor-type flash units can be used with the EVOLT E-510's Manual shooting mode as long as the sync voltage does not exceed 6 VDC. Third-party TTL flash units will not have TTL capability because the contact pins in the camera hot shoe probably won't align with the contacts on the flash. In addition, the TTL communication with the EVOLT E-510 may damage the camera circuitry or corrupt the camera firmware.

Probably, but depending upon your camera's support for standard external flashes, it may require some persistence and some workarounds:

Absolutely. If done properly, the use of Flash, while not a Web standard technology, can be a fine addition to a Web standards compliant site. There are even methods to insure your Flash will not choke the W3C's XHTML validator. An all-Flash site, however, would probably not fall into that category. Macromedia is a very forward-thinking company however and Flash does have a future on the Web, so time will tell.
