Little help

[EdithGn]

Hi everyone, im 100% here and i've been reading and making notes about everything because i love photography and want to do it correctly. I have a question about the "exposure" since my camera just has the option for ISO speed and exposure, im a little bit confuse because i cant find the "aperture" option, i dont know if the exposure and aperture option are the same (in my camera) i have a digital ELPH Cannon powershot SD20 and what about the shutter i cant find it neither.


Thanks !!

Aperture is a component to exposure. Exposure isn't a setting, it's a combination of 3 settings. Aperture, Shutter speed and ISo each contribute to exposure. Aperture is the size of the opening in the lens. The Shutter Speed is the duration of time the sensor is exposed to light. ISO is the sensitivity of the sensor to light.

By adjusting all 3 elements, you can control the exposure you get.

From what I can tell, there is no way to adjust aperture or shutter speed on the camera: it always does those by itself. That being said, that's very quick research: I'd be able to tell you for certain if I had the camera in hand.
