Song Sparrow: Kennebunk, Maine, USA — The Song Sparrows were back under the feeders at my backyard photo blind before any other migrant bird. That is too be expected, as they are early birds in the fields and marshes here in Southern Maine as well. However, this will be only the second year we have had them in our yard regularly so I was happy to see them. They don’t sing often around they yard, but I caught this one up on the fence behind the feeding station, giving song. Technically this is an interesting photo for a couple of reasons. First it is an extreme crop from the full frame as even at 600mm equivalent, the distance was great and the bird was tiny (a 2.8mp crop from a 20mp frame, or the equivalent of a 4200mm lens), and second because I used “Machine Learning Super Resolution” in Pixelmator Photo to enlarge the crop and restore some of the resolution (bringing back up to 6.8mp). Depending on where you view this (on my blog or on FaceBook or Instagram) and on what size screen you view it on, you may or may not be able to appreciate the level of detail the combination of the ZEISS lens, the Sony sensor, and the Pixelmator software was able to render under challenging conditions. It will not stand up to pixel peeping, as the Machine Learning part becomes evident, but it is pretty impressive at normal viewing sizes. Sony Rx10iv at 600mm equivalent. Program mode with my custom birds and wildlife modifications. Processed in Pixelmator Photo and Apple Photos. ISO 200 @ f4 @ 1/500th.
