Hi BrennaRN,
To answer your question "What software are you guys using", we are using Adobe Photoshop, this is a professional photo editing software.
One person in the theard also used Coreldraw, a powerful tool too, but less popular these day.
If you are interested to start doing some photo editing i would suggest maybe a more basic software then the 900$ Photoshop

a software like Adobe Photoshop Element (ibasic version of Photoshop) for around 90$ or GIMP a very powerful photo editor (comming from linux, but works great in windows) that is free, but a little less user friendly then Element.
Have fun
