back when i was scrapbooking more, i read a quote(i don't remember the author) that went something like this, "if your pictures aren't good enough, you're not close enough!" and this has always stuck with me, sometimes it sticks TOO much with me! i love to get in there close, especially with children.
so if you're trying to improve the quality of your photos, try getting in there closer. most all digital cameras these days will give you a light or a beep or some sort of sign to let you know that you're in the focused range, otherwise you're going to get a blurry image or the camera just won't let you take the photo. so... try it & have fun!
