I chose the automatic exposure settings on photo A and liked the look of it because the alpaca had good lighting. If there wasn’t a shadow on the left it would look even better. For this photo I slightly lowered the exposure.I chose this picture from group B because of the moody feel the low exposure brought.
I chose this photo from group C because the alpaca looks whiter than the wall with this slight exposure. For photo D this was also with a slightly lowered exposure.
light needed to be more from side to keep shadow off background. Also helps to keep object further from background
B is too dark and light area in background is distracting
