Change Aperture

[khopev]

Hello,

I am trying to change the aperture. I am watching youtube videos and they are telling me to press down the the Av button while I turn the button right behind the shutter button. It is not changing it at all. Is that an error? I have a Canon Rebel T6. Thank you!

khopev, 

We are sorry to hear this occurs.  What lens are you using on this camera? 

[khopev]

I am using the 18-55 mm lens. Just took two pics outside and they are way too bright. I am set on M and across the top of the screen is 1/200, F5.6, and ISO400. Thanks!

What made you set those parameters? Where you going by the meter in the viewfinder?

What mode are you in? You need to be in M

"You need to be in M"

Maybe! But we need to know what lens before stating that.

What does the lens have to do with it? They all change apertures.

I am in M, lens is 18-55m, across the top of the screen it reads 1/200, f5.6, iso 400. Thank you

Why are you in M mode specifically?

Have you tried taking images successfully in Av or Program mode?

No matter what it says across the top of the screen this is overexposed.  Try doing the same thing with the camera in P mode.
