I'm relatively new to photography and I'm wondering

>>2936631
Aperture priority is the pro auto mode, if it's a shot I care about I use manual, if not I use aperture priority.
Generally the wider your aperture is, the softer the image will be. And once you go past a certain f stop, you'll lose quality as well from diffraction.
Aperture priority is basically an auto mode where your camera won't change your lens to dumb f stops.

Good question. I wondered the same

Because shutter speed has little to no effect on most scenes unless there's motion, so it's similarly of little consequence to let the camera decide the appropriate shutter speed for the f/stop you've chosen.

I mean, you could go to all the effort of choosing 1/320 or 1/640 or 1/500 over and over again, but why? What does it gain you?

I would much rather keep control of my aperture and let the camera decide on shutter and ISO for most stuff. Unfortunately I shout largely on film so full manual is the only way.

How new are you?

>>2936631
Aperture priority is primarily for the control of the DoF, be it paper-thin or massive for landscape. When you want control on movement, freezing or blurring you use shutter or timing priority. If you want consistent exposure on a series of shots you use manual. It is that easy.

Unless you buy a camery with apertue priority like all eos cameras for 35 mm film

I'm an M42 fanboy.

>>2936742
but bruh he shoot MANUAL

I usually go for a canon body and a m42 lens to have the best of both worlds. Works kinda well :)

full manual is just aperture priority you have control over, knee grow. There's nothing unfortunate about being fully aware of the exposure conditions for your medium of choice.

PAS is for people that can't do simple math or memorize a simple table.

It's just a good way to shoot if you're not shooting something super important, it's fast and pretty much effortless and still gives you a pretty high amount of control over the camera settings, I put it in manual Iso also so the only thing the camera has control of is the shutter speed which I can indirectly control through aperture and Iso if I want to
