Step Up To A Larger Filter
Q) I'm about to purchase a 28-75mm lens for use with my digital SLR. It has a 67mm diameter lens; however, I have a 77mm circular polarizer that I would like to use with the new lens. I also plan to purchase a 67-77mm step-up adapter so that I can use these larger filters on the smaller lens. My question is, how will the quality of the image be affected by not using the exact size filter required, i.e., a 67mm polarizer on a 67mm lens?
Q) I just bought my first digital SLR; actually, it's my first SLR, too. I've been spending nights and weekends trying to learn all of the various features, but there's one feature that I'm just not getting. Depth-of-field preview doesn't seem to work-all it does is make the viewfinder darker.
Q) On my camera, I have the option of erasing my images, formatting my memory card and doing a low-level format of my memory card. Which should I be doing?
Q) Red-eye has been a problem that I thought might go away with my new camera. I talked to someone and they were talking about red-eye reduction and red-eye correction. When I took a picture, they said that my camera didn't have red-eye reduction because the flash only fired once, but my manual says it does. What's going on?
Q) I read your HelpLine column a few months back about photographing fireworks. Thanks for the tips. I really like the shots I got, but I'm wondering about overexposure. Also, the center of many of the fireworks seemed to be just plain white with no color. Was I exposing wrong?
Q) I appreciate your recent advice on keeping files backed up (the June and September issues of PCPhoto). I'd add one more caution: If you're using an automated backup program (i.e,. one running automatically on a schedule), be sure that the program is actually running and that there's still room on the drive to which you're backing up...
