I then found another of the same type of flower resting above some moss. Like the last picture, I added the same warm filter to this picture. With these last two pictures, and many others, pictures you can tell where the focus begins and ends. I feel this is both an advantage and disadvantage to having a lower aperture lens. The lower aperture allows for crisper focus and better night pictures. But, if you keep the focus on f2.8 the entire time, there will only be a small portion of the picture that is in focus.
