Iso

FlashIso 400Iso 5000Iso is basically the film speed. It refers to how sensitive the film/pixels are to light. when using the iso in my pictures it showshow graining the pictures get when u put it on a high ISO. With the five thousand one right above you can see how grainy it has gotten. When using the flash it takes out some of the lights you want to see but it doesn't give you a grainy picture at all. You have to becareful when using a fast ISO because it tells us how much light comes in and at what speed.
