Just bought this camera based ongood reviews. First, I have taken two shots, the first one my subject has red devil eyes. I have read the manual and adjusted the auto focus with red eye reduction but the eyes are still flaming red. Photo was taken indoors with somewhat lit up room. Is the lack of light my problem? and if so, what is the best mode to take indoor shots with low background lighting?
2nd problem: the cf card does not get read by my memory card reader. I just bought a HP multimedia with a built in reader. I spent 3 hrs. yesterday with hp support and nothing is resolved. Has anyone every experienced using the cf card that comes with the camera and have same problem? When I hook up the camera and download it captures the images, however, i thought it would be convenient to have the built in memory reader and just insert the card.
Please, any advice? Many thanks, in advance.

The red eye is caused by your subject looking down the lens and the flash being too close to the lens. Get them to look more the other side of the camera rather then at the lens. Sometimes they can be looking not even at the camera and get mad red eye when this happens you have no control over it because the eye is quite good at reflecting light.

All cameras using built in flash exhibit some redeye at times. The only way to completely eliminate redeye is to use an external flash where the light emitted from the flash tube is either sinificantly (four or fives inches seems to work well) above or to the side of the camera lens. In the case of the A75 and most other digital cameras that don't have external flash sync capability, a slave flash can do the job provided that the visible light emitted from the camera's flash is masked. This can be done by placing an infrared filter over the camera's flash window. Nothing fancy required! Just an unexposed developed piece of slide film works like a charm. (I tried this with several camera/flash combinations and the results are astonishing.) The filter (a.k.a piece of film) allows the infrared component of the flash to pass through and trigger the slave flash while blocking out the visible light thereby preventing any chance of redeye. Credit for this tip goes to Peter iNova the really savy author of ebooks for various Nikon and Sony cameras.

A pseudo method of removing redeye can be of course be done with most digital imaging editing programs but that reqiures that each affected image be treated individually which takes time.
