Photography is simple. See something you want to take a picture of- take off the lens cap- point the camera and press the shutter. Voile! Thats all there is to it! Thats true if use and iPhone. Even better with an iPhone because you don't have to worry about taking the lens cap off. So why not use your iPhone for all the photos? iPhones don't give you control. They are essentially a point n' shoot camera. A DSLR or Mirrorless camera gives you options, it gives you choices, it gives you control. The reason us pros use DSLRs most of the time is because we can use a wide variety of lenses. We can get a big file so we can sell and have it up on a billboard. But, mostly importantly, we use them because they allow us to have a lot of creative control over light, over the shutter and the aperture and they allow us to create. Using a DSLR/ Mirrorless is like having blank canvas and lots of paints and brushes. That is why Program mode is paint by numbers photography. If you use Program mode you paid a lot of money for a point n' shoot camera. So, photography is simple. Learn how your camera sees the world. Figure out what story you are trying to tell and then use the way the camera sees to create great photos.
