Neighbors Magazine – Lime lake

This image of Lime Lake is this month’s cover of Neighbors Magazine.

If you have found your way to my blog via Neighbors, keep checking back as I will be posting additional images from the current issue with a bit more background information than is contained in the publication.  See Neighbors for information about a special promotion where you can order this image from Koertens Fine Framing and Gifts in Stevens Point, WI at a reduced price until October 1.

Beams of light radiating from the sun become visible when shadows are formed and light is scattered by particulates in the atmosphere. These crepuscular rays can be seen forming at three distinct cloud banks above Lime Lake in eastern Portage County, Wisconsin.  If conditions are just right, the rays can be seen traveling the entire sky to the opposite horizon.

Lime Lake is one of the lakes in Portage County draining initially to the east.  A remnant of our glacial past, it was formed by a huge block of ice left behind by the retreating glacier.  The ice chunk depressed the ground underneath and was subsequently surround by glacial till forming a depression that would become Lime Lake. The image was captured from the western ridge overlooking the lake. Drainage for the lake exits through the gap seen in the distance.

This image is an HDR and was constructed from five separate images. This technique allowed me to create an image that shows a greater dynamic range than is typically available in a single exposure. There is far greater detail in the shadows and highlights than the camera can capture in a single exposure but similar to what the human eye can perceive. The images were captured using a static aperture but variable shutter speed resulting in a full f-stop between images. My camera was on a tripod and I used a timer and mirror lock-up to prevent camera shake during image capture.  Images were combined using Photoshop  and a Photomatix tone mapping plug-in.
