OK, on with the first tip...
I want you to get close to your subject... I mean really close and when you think you're close enough, get even closer. Fill the whole screen up with your subject and maybe even closer by just taking a picture of their face. Many times we just take a picture but there are things in the background that distract us away from what we want people to see. If you get closer those distractions disappear and the focus of what you're trying to communicate in your picture becomes more clear. Sometimes you want to take a picture of your subject's smile but if we don't get in close it's hard to see the smile. If we get in close to where we're only taking a picture of the face, you see that smile nice and big. Remember this is only a tip, it's not a rule, sometimes a picture is better at a distance.
OK, you can do this two ways, one way is to physically get closer and the other is to use your zoom. Fill up your screen as much as possible with your subject. Practice this tip this week and post a link to your picture in the comments here. I look forward to seeing what you come up with.
First is an old example from before I learned to get in closer. I should have zoomed in so that you only see all of her instead of the bouncer, coffee table, rocking chair, toy, etc... The second example is getting in closer so you see only his face and not the stroller. You can see his expression without any distractions.
