I was going through older images to look for some colorful images to post on the blog. These were from my old home by my pond. This was on the other side of the pond probably 20 feet from my camera. Even with a 400mm lens the image would not have filled the frame like I wanted, so I started experimenting with different ways to get closer. So by adding a short extension tube, then a 1.4x teleconverter, then another extension tube I was able actually starting to get what I wanted in the frame. It took hours of experimenting with different sized extension tubes, teleconverters and teleconverter and extension tube placement for different results resulting in a large image on the camera’s sensor.
