Example of ISO 1600
Here are some examples of ISO in photographs that I have taken:
I went to Sea World with my family and brought my camera. We went into the eel tank room which was really dark. I wanted to take pictures of the eels but my aperture was open as wide as possible and my shutter was as slow as possible (without causing the picture to be blurry) but I still couldn't take good pictures of the eels. I was forced to bump my ISO up to 1600 so that my sensor would be fast enough to record the light. I caught this image:

Now, that image is okay. However, it might be hard to see how grainy and what bad quality it is. Here is a zoomed in part of the image so you can see how ISO 1600 affected this image:
So you can see that ISO 1600 caused some SERIOUS grain issues and caused the picture overall to be extremely fuzzy.
