Your camera's manual exposure settings can be complicated. Rules of thumb are useful for figuring out the right settings to go with. For example, if you're out and about taking street photos, use the f/8 rule for your camera's aperture.

Your camera's aperture is how much light it lets in and it's measured in f-stops. The wider the aperture, the more light it allows in, and a narrower aperture lets in less light. This can affect the sharpness of your photo, and for street photography, f/8 is a good go-to setting. How-To Geek explains why:
For the camera settings, we once again turn to the always reliable aperture priority mode. Arthur "Weegee" Fellig famously said — at least supposedly — that the secret to good street photography was "f/8 and be there." In other words, if your aperture is set to f/8, all that's required from you is to be in the right location to press the shutter button and you'll capture almost any moment. It's just up to you to find the moments and locations worth capturing.
This aperture ensures pretty much anything will be in focus and properly exposed when you're ready to shoot, so it's a good setting for on-the-go photography. For more tips on how to take good photos on the go, head to the full post at the link below.
