It started off as a hunt for the current “resting” place for historic locomotive #10 of the Amador Central/Foothills Railroad, but ends up with photographs of oaks leaves on railroad ties. I did eventually find the locomotive. It was one spur further than I expected and makes for an interesting backyard view for some homes.

While not evident, this is a long exposure photograph taken nearly an hour after sunset. With the f/stop setting selected, the shutter speed was calculated by first bumping up the ISO to within the workable in-camera meter. In this case, ISO 400 and 30 seconds yielded a “correct” exposure. Backing out to lower ISO of 200 (and less possibility of grain) meant doubling the shutter time to 60 seconds. Of course, increased shutter time mean potential digital noise, but I was going to chose that over grain. A personal choice really and may depend on the strengths and/or weakness of your camera.
