There is a high contrast between the light coming through the window and the shadow on the opposite side of her face. Taken as Allison was looking out the window.
This is taken down by the Mississippi River at sunset. The low colors of contrast given at sunset with that low side light gives this appeal to the eye.
This is another photo taken on the cruise ship. This was taken also in early morning. With the sun coming up in the east, we create a high side light. The sun at this angle gives such blue water, I contrasted this against the white railings.
This photo was taken of the water in Lake Winona. This part of the water seemed so pure and clear. Using the light effectively we get the leaf and water to pop out at us more.
This is a photo taken at Lake Winona around midday. Capturing the sun as is and letting the light of the sun fill the frame we get a natural fill light.
