Hi Jenneve,
Welcome to TPF. We're almost neighbors, I'm just north of you in Missouri -- other side of the Mason Dixon. Where abouts in Arkansas are you?
Three of the four photos you posted are backlit without fill. The real bottom line is you don't want to do that for a lot of reasons. If you're going to have strong bright light behind your subject then you really need to balance that backlight with forward fill. Typically that means a flash.
When the light behind your subject is very bright your exposure has to either 1. get the backlight well exposed and so underexpose the subject or 2. get your subject well exposed and so overexpose the backlight or 3. get them both wrong. In these photos you and your camera basically went for option three. In the discipline of Fauxtography option two is usually considered the professional choice. In the discipline of Photography options one two and three are all considered unacceptable which takes us back to front fill -- you gotta do it. If you're going to shoot portraits outdoors in backlit conditions, front fill light is in the end a non-optional requirement.
In addition to the exposure problem you usually end up with a color problem. Here's one of your photos in a side by side comparison:
The sunlight in the back is one color while the open shade in the front is different -- much bluer. As a result the skin color of your subject turns blue. Again the solution is front fill from a flash which is the same color as the sunlight. I lightened your subject and adjusted the color, but I can't stress this enough: Don't look to post processing for what you should have done right with the camera.
So the message is, if you're going to continue to photograph people in backlight like this you really want a flash for Xmas (one you can use off camera).
So nice to hear you're excited. Hang around here and there's lots of folks who will help out.
Joe
