Playing for over 5 days and many hours trying to come up with that Combo to get the photo I wanted...Sharpness, good dof,and lighting. These bluebirds move fast. Shot was taken with a Nikon d700 with a Tokina 12-24.an excellent lens. It was taken with a tripod and a remote good for 300 ft...The camera was about two feet from the bird house on manual focus.ISO of 1600 and f-11.Tried to end up with a shutter speed of 1/1500, Camera set at 7 fps. No auto of anything except white balance. Ended up with 1 in 15 shots that could be used and to get a great one would be 1 in 50... Well worth the day.. Probably taken over 300 shots in different places and conditions... A good learning curve....
