Bogy the Dog

This is Bogy, my fathers Dog.

His head turned to the side because of the extremly narrow focus area. If a picture was taken of his nose, the rest of his head would be out of focus. The exercise of this shot was to get as much bokeh as possible, thus the f1.4. I realize f1.4 is not the butter-zone of this lense, but once again, I was trying narrow DOF and lots of bokeh.

What is good about this photo and what is bad? Lay it on me.

I would have preferred the illumination on his muzzle to be the same as that on the back of his head.

Well, the bokeh is beautiful, so you achieved that goal. The problem is that the back of his head is in sunlight, and the front is in shadow. This gives you two different white balances, and at the opposite ends of the spectrum at that. The WB looks good on the back of his head, but his muzzle is too blue. Not much you can do without some serious (for me) processing work, but I'm sure someone here could fix it in about 20 seconds.

Great crits guys. This is exactly the type of comments I need as I'm beginning to learn some of the art.

I would also say the image looks under exposed, also the bokeh is good but I would like to maybe see more of the dog as the crop is a bit tight for my taste.

The eyes are also too dark from being in shadow and could do will a boost of fill light in lightroom or similar. WB has already been mentioned as it's a little too cold. Accurate WB isn't also important to be accurate, for instance if you are capturing a warm moment, then it can often look better to use a warmer WB.
Also it's nice to see a catchlight in the eyes if possible, below is an example.

A little fill flash would have helped balance it out a bit. Also I would have shot it more face in than off to the side and have tried vertical crop as well. I realize dogs are hard to photograph and you only have brief moments sometimes before the move off or become uncooperative. Good effort, keep up the good work.

This is a very educational thread. It should be used in a textbook.
