Best software to give profession touch to your home made Photos & Video?

Hi Readers once again I am here to share my experience about how to give a professional touch to our home made photos and video. Why I am discussing this issue here because many my close friends who are having very costly video recorder or photo camera and do video recording and photography when ever they go for outing or their any function in there home but they not able to give profession finish to their photographs or videos so never show their photos and videos to people or hesitate to share it on social networking sites, Facebook, Google or youtube. And many of my friends send  email and requested me to suggest  a good software which can use to give a professional touch to our home made video and photos and enable us to add, edit and give a professional looks in my videos.
