I use
Windows Live Photo Gallery
You can re-size, adjust contrast, crop, etc all at one time!!
Turn on the
flash when taking the outdoor pics and you will be amazed!!
EVERY outdoor pic I take that is less than the range of my flash (about 20 feet), the flash is
ON!! 
When you get good, you will do the
Adjust Detail to increase the sharpness.
It makes a big difference with my Nikon pics. (My go to camera for tractor pics is a Nikon D70s)
Sun lighting on the back, flash on the camera side,
even makes a Gravely look half decent!!
Windows Live Photo Gallery should be already loaded on your Windows 7 computer, if not it is a free download here;

I'm starting to sound like a software salesman, so I will stop!!
P.S. Next to Cubs, I like photography best!!
