I really don't think that there's much to say about Day 4. I just had to take a picture of something that was green. Simple for the most part.
What I learned today was that there is practically nothing in my home that is green. I own 1 green shirt and a green dress if that counts as anything. So I had to go outside and take what nature gives best. If there is anything else that I probably could have learned from taking this picture is that I need a macro lens. Macro lenses allows you to be able to focus on subjects that are closer to the lens. I do feel like my 85mm has gotten fairly close and still focused (I did have my aperture at 1.8, so only the front, side leaves are in focus) but not as close as it possibly could have been.
