do you have any "photo editing software" on your computer?
everybody uses the term "photoshopping" when you edit pictures because Microsoft's program called "PHOTOSHOP" is definitely the most popular of it's kind....but I use something called "Photohouse" which was designed by a company called "Corel" to compete with Microsoft's "Photoshop"....and I'm not sure why I use that one, I just got used to it because I bought Corel's "WordPerfect/Paradox/QuatroPro" package years ago and they included "Photohouse" in with the other software....
anyway, if you've got something like "Photoshop" - use that to open up any picture files that you have and just sort of play around with some of the different things you can do with your pictures...but remember, if you alter a picture, save it with a different name so you haven't altered your originals.
OK - now about that picture...I do see something where Gina circled....not sure what it is, though. It's just like not in focus in that area next to the tree.
