When people ask me tips for beginners, it's impossible to give them one short answer. There is so much to photography, and you will never stop learning. Im not going to ask you to use specific equipment or use specific settings here. Equipment or settings will never get you good pictures alone. Its you who take the shot, not your equipment (well it kind of does but you get the point). Here is some tips I wish I knew when I started out!
1. Imagine the image in your head before you take the shot
Before you go out and shoot, have a plan, or an image in your head that you want to capture. Your goal is to come as close to the photo you are imagining as possible.
For example you are going out with a friend to take portraits. You remember you saw a picture online of a badass picture where it was side lit and the model was looking towards the light source. It was taken from the waist up and there was a very shallow depth of field. Try to recreate this as much as possible, and when you are happy you can try out other things. Planning is important, not planning like time, location, outfit, hairstyle and so on. Planning like having a picture in your head before you take it.
2. Dont make it to complicated
Make it simple. The background can easily get very busy and distracting if there is too much stuff. Try not to have so much in your frame, you don't need it. Make it easy to guide the viewer to where you want them to look.
3. Have depth in your photos
Having depth might sound complicated, but it's easier than you think and you probably do it without even thinking about it. Think about layers when you shoot, with foreground and background. For example, if you are out shooting a model and you find a nice wall. You decide you want to shoot from straight on, make the model come out a meter or two to put some depth in the picture with a clear foreground and background.
4. Get inspired by others
If you are interested in photography, you probably watch a lot of photography. The easiest place to find good photography is Instagram. Find a favorite photographer or feature account and watch the photos. Analyse them as you see them, Why do i like it, and how can I recreate it. Dont copy other people, but see how they go on with shooting and editing their pictures and get inspired.
5. Put more interesting stuff in front of you camera.
Hands down the most easy and obvious way to take better pictures is to have more interesting stuff in front of your lens. This is not a tip most people think about, but this is the easiest way to get good photos. It does not matter if you shoot on an iPhone or a 5000 USD camera, a picture of this castle on an iPhone will always look better than a picture of something uninteresting on a super expensive dslr camera.
