The significance of f-stop numbers

I’ve been diving into how f-stop numbers affect depth of field and exposure, and it’s fascinating how just a single stop change can change the whole vibe of a shot. For instance, going from f/4 to f/2.8 doubles the light but also impacts the sharpness of the background significantly. Does anyone have a particular f-stop they swear by for portrait photography?

I love using f/1.8 for portraits — it’s great for that creamy bokeh effect while still keeping the subject sharp. It really adds depth to the photograph without losing too much detail. Do you find yourself leaning towards wider apertures for certain lighting conditions?

I find f/2.2 strikes a nice balance for portraits, maintaining sharpness while still giving that soft background. Have you tried that aperture for your shots, @amelia-ros47?
