So, at risk of being laughed at..... I have a couple of questions that may make me sound like quite the amateur, but hey, that's what this site is for, right? I have a Pentax k100d super, and I am having MAJOR problems with manual focus. When I'm looking through the viewfinder, and trying to focus on, say, someone's face, it appears to be focused, but once i get the images onto my computer, it's blurry? Any suggestions here? It's getting REALLY frustrating! I know there's a little adjuster thing above the viewfinder, but I'm not sure how to properly set that. (I would post an image, but I am currently using a borrowed laptop, b/c my comp is being repaired. ) Also, what is the BEST way to set white balance. I find that my camera doesn't do the best job of automatically setting it. I've read/heard about the use of white cards, and gray cards. What's best? Setting it in your camera to 'tungsten... daylight' etc or using a card, if a card, which one? Gray or white? THANKS EVERYONE!
