[QUOTE="Rich Rohrich, post: 1421542, member: 16241"] That's some of your best stuff to date Kav! Keep 'em coming. A couple of quick flash tips to keep in mind : - The flash exposure is totally controlled by the aperture you set - For a given f stop there is a specific flash to subject distance that needs to be maintained for a "correct" flash portion of the exposure before the inverse square law steps in. For example if the correct flash exposure at f8 = 5 feet from flash to subject then moving the flash 10 feet away (2 times the distance ^ 2 = 4) will only allow 1/4 of the flash to hit the subject . Fun with physics. - The ambient light exposure is controlled by the shutter speed and won't really impact the flash portion of the exposure. - If you have enough flash power you can set the shutter speed -3 or more stops under the correct no flash exposure and pretty much kill the influence of the ambient light and let the flash be the main light source. - The wider the lens is open and the higher the ISO the greater the "effective" range of the flash. The inverse square law physics will always be there but you can extend the reach of the flash by playing the physics you can control (aperture and ISO) As I think about it this is all stuff you probably already know:whoa: [/QUOTE]
