This is about capturing only. I will start:
- rule of thirds is a good start for framing. there are other rules you can follow but this is an easy starter. and many cameras got guidelines for it.
- go down to your subject. (or up) especially with kids or pets this makes a huge difference and gives the viewer the feeling they are in the scene.
- Use the trick with the jaw line in your portraits
- Prefer Aperture priority as aperture can have a huge impact on your photos look. more so than the other parameters. The camera can handle the rest for you.
- Shutter speed: you should aim for “1/focal length” or faster to minimize motion blur in your photos. Be it from fast moving subjects or you not being 100% steady. Image stabilization gives you a bit more room but this is a good rule of thumb. ( 1/50th if you use a 50mm lens e.g.)
- Use exposure compensation: It can often save you from going fully manual to get the right exposure.
