ISO

For the first picture I took of my partner it was on auto flash. You can barely see the Christmas lights in the background. So flash is bad to take if you wish to take pictures of the light. Auto flash is good if you wish to take pictures of a particular subject.

For the second photo I used ISO 50 which makes the lights stand out, but makes the person not vi sable. The lower the ISO the darker the person will be.

For my third picture I used ISO 5000. This made the picture come out very bright so you can see my partner. The higher the ISO the brighter the picture will be. This is good to use in dark settings.
