Contest Entry - Master the light with manual photo setting - ISO

Here's my contest entry, featuring my baby shoes with bells on them:

Camera: Tracfone Samsung

ISO 100

ISO 200

ISO 400

ISO 800

This lesson wasn't so hard to do, since it had pictures that accompanied it (https://steemit.com/hive-197809/@life.pics/master-the-light-with-manual-photo-setting-understand-the-iso). I did notice, however, that the ISO on my cellphone camera started at 100 instead of 50. Interesting.
