I went a walk around Kirk Loch (Lochmaben) on Sunday and heard a wee wren singing his heart out. He was quite high up in the tree and I only had my Nikon 70-2000mm lens with me. Also I was trying out back button focusing, shooting in both RAW and JPEG. I decided to try and capture him, after all nothing ventured… Downloaded my photos when I got home and although it was a nice photo, I had to crop in a lot. However the jpeg image was not great so decided to try and work on the raw file. Really glad I did because the difference was amazing, a much clearer, sharper image.
