ISO 100
Explanation:
<u>An ISO of 100 with less exposure and f/16 would be the ideal setting for photography on a bright sunny day that one can have a day out in.</u>
Low ISO makes the exposure to the sun less drastic and brings out the color and depth perception in the picture.
<u>In darker times, the ISO is increased to achieve similar quality</u> of detail in pictures as is achieved with low ISO in sunny days.
The best answer here would be pencil.
Artists use pencil to make sketches and create studies. They then use these sketches and studies to create their final larger piece. They use pencil because it's quick, can be corrected, lightweight and easy to use. Before pencils artists would make charcoal drawings but once we had pencils it made sense to use them as they aren't messy like charcoal.
A gesture sketch is a quick loose form sketch to capture the subjects basic form and movement
