For the most part, I have used the base ISO setting of 100 as light conditions were generally good; my photos were captured outside and mostly on bright days.
In these photographs, I decided to raise the ISO because the sun was setting and natural light got dimmer.
Because these three were taken low to the ground, limited light was entering the camera lens; therefore I raised the ISO setting to increase the sensitivity of the camera's receptor.
I composed this image by purposefully leaving about 2/3 sky space while utilizing the rule of thirds to align the building's prominent feature, it's window on a power point.
