I get asked sometimes if a photo is “real”, that is, has it been photoshopped, or is the photo a multiple exposure. I do not use those techniques. Sometimes I get asked about the size of the moon, or sun in a certain photo. Why is it so large? Well, usually when I take a photo of the sun or moon, they are usually positioned low to the horizon anyway. When the moon or sun is low to the horizon, they appear bigger to the human eye. Here is a good explanation from the good people at Old Dominion University. The lens one uses also makes the object appear bigger. This photo was snapped using a Canon 100-400mm lens. 1/30th of a second at F5.6 at 5000 ASA (ISO), on December 26, 2014 at 9:49pm. The moon moves fast and is considerably brighter than the city. This city angle is  not as bright as other angles, so my unique problem was to get somewhere in the middle regarding exposure. Give enough to the city in exposure without blowing out the moon. A bonus, especially for Boston, was the nice green tail of the Aer Lingus shamrock, below left. Copies for purchase, of this, and of all my photos, can be found here.
