Read photobooks, look on the internet, soak it all up! You don’t have to copy everyone else’s work but it's useful to have inspiration and to see how other people compose images.
If you can avoid all of the other distractions, then using the internet to do this is a great idea, but know what you want to find and then go find it!
Some of my favourites are Nigel Danson, James Popsys, Scott Choucino (these three have really active social media and YouTube channels and I have learned a TON from them!), Galen Rowell and of course, the master: Ansell Adams.
These aren’t the only photographers out there, so find ones that you like and learn about their photography!
