>>3605729>>3605729Put it into aperture priority. Auto on everything except aperture on the lens. Experiment with that until you understand how ISO/shutter speed/aperture work together. Once you understand that start experimenting.
Most people go through a bokehwhoring phase at the start where they keep their lens in F2 and below for that creamy background. No shame in that. Once you get bored of that, start experimenting with slower shutter speeds to blur subjects. It'll come together.
