One of the fascinating things for me about photography is how changing the focal length of the lens you are using can subtly or dramatically change the look of a photo. Going from say 17mm to 300mm would be dramatically different. Which is the subject of a post I want to do someday, where I try to keep the subject approximately the same size while changing the focal length drastically... say from 8mm Fisheye to 300mm Telephoto.
What I wanted to see here was how differently a photo would look using a 100mm v. a 200mm lens. This was spurred on by taking this first shot of an ornament given to my family by my brother in law for Christmas. After taking the first one I found myself wondering if I could take essentially the same shot with my old manual focus 200mm lens.
I was intrigued by how similar they looked after processing. The older lens lacked contrast and the exposure was not quite the same, but they are quite similar upon initial examination. If you look closely though there are subtle differences some due to having to move the tripod further away to keep the relative size of the ornament the same and some due to the change in focal length exclusively.
I think I need to pursue this line of investigation more closely. It would be a fascinating thing to explore in a blog post when I have the time to sit down and write in a lucid manner.
