Camera settings?

Question

Hi, I have a Canon PowerShot A570 IS. Recently I've been playing around with some of the different settings, and have figured out some cool stuff to do with slowing the shutter speed, however I still don't understand the aperture setting. What is the effect on the picture from increasing or decreasing the aperture? When should I use a high aperture, and when should I use a low one? Also, anybody with a similar camera (or familiar with this one), what other interesting stuff can I do besides "time lapse" type photos and messing with the aperture? I need some inspiration and information on how to do it...thanks!

Answer 1

Aperture or f-stop controls the depth of feild and light. You should use high aperture when you want a lot of depth in a picture, like landscapes, and that should be set on about 22.
You should use a low one when you want the background blurry like when you're taking protraits. It will focus on the person, and make the background blurry. And that should be from 9 to 5.6 depending on the weather.

i'm going to attempt too! handbook helps you to override what the digicam thinks could ensue. P, vehicle, Shutter priority or Aperture priority have some element to automated linked with them. ninety% of the time, the digicam is in all possibility good. yet, have you ever taken a backlit photograph and had the venture look like a silhouette? that's a case the place the digicam is determining the well-known brightness and determinig the publicity, and the digicam is inaccurate. via utilising handbook controls, you could overexpose the scene (and for this reason suitable disclose the venture), you're able to enable in extra easy than the digicam thinks could be there - the two with a slower shutter velocity or a extra robust aperture.
