Opening Raw files - Photography quick tips

When I first started shooting, I learnt Raw files were the best for data retention. The thing is, I didn't know or understand why I couldn't open them. 

You need a program on your computer that can read a Raw file.  

Adobe photoshop and light room are the two I use. But most camera brands have their own programs that can read them. Nikon's one for example is called ViewNx.
