Iso is the speed of how fast the camera pulls the light into a picture. I didnt successfully use the tool correctly as you can see in the photos. If the project was done the correct way the light in the pictures would differ in every photo. The reason you would change and use iso instead of flash is because with iso you can get the exact amount of light you want in the photo. When using fast iso you have to be very steady because the pictures will be very blurry.
Fill in flash is a camera tool. It can be used to add light to pictures taken in dark places, or it can be used to take away uneccessary shadows. In the first photo of myself the fill in flash was on and you can see clearly there is no shadows in the photo. In the second photo the fill in flash was off and now the natural shadows that should have been in the first picture are now in the second picture.
The objective was to take two photos with metering. Metering is when the camera measures the light in a picture. In the two photos I took, I didnt accomplish the objective. If I would have did it correctly you would see a major difference in the light of the two pictures. This tool helps you when there is lots of light or too little light.
