Inspired Photography: Snow Crow Angels
One day last week, when there was still snow on the ground, I was up before the sun. I went outside, and the snow was still freshly cold with no evidence of melt. The place where I leave food out for the crows (they are birds too!) had some interesting marks from the previous day's meal. I thought to take some photographs (quickly since the temperatures were in the single digits) with a macro lens. I wanted to do this before the sun rose and cast shadows on the scene.
Remember that snow throws a blanket, blue reflection in the white balance department. This can be fixed in camera by adjusting the temperature, or in post-processing.
It is almost impossible to use auto focus on the snow because there is very little edge. Without contrast the sensor in the camera can't sense much.
Better to underexpose. This will salvage some of the detail in the image when it comes to post-procesisng.
