what is ISO and how does it affect your camera

ISO controls the amount of light your camera lets in, and therefore how dark or light your photos will be.

Low values, such as ISO 100, are best for a sunny outdoor shoot. For shooting at night — or indoors with dim lighting — use an ISO of 1600 or higher.

What does a high ISO / low ISO mean? What effect can this have on your photos? What is meant by visual noise?

The higher the ISO number, the higher your camera’s sensitivity, and the less light you need to take a picture.

The lower the ISO number, the more light is needed to properly expose the image

 higher ISOs can lead to degraded image quality and cause your photos to be grainy or “noisy.”

visual noise is when the photo is grainy and is effected by bad lighting conditions

This is an example of a high vs low iso

My photos

IOS = 100

IOS = 6400

These are all examples of photos i’ve taken with different ISOs. we went around the school finding different textured things
