Do you have a black dog? If you do, I'm willing to bet you have more than a few pictures of him/her looking like a big black blob. Am I right?
So I'm going to tell you a little secret about photographing black dogs... are you ready?
You need light.
Whether it's natural or artificial light, you need it to avoid the big-black-blob syndrome.
This is Jack. He is black as black can be - not one strand of hair any color but black! During his session, we stepped into the narrow side yard, and I immediately paused and fist-pumped because of the beautiful late afternoon sun streaming in over the fence. So I had Jack face the light, and look how it lit up his eyes and black fur!
And now a bonus tip: a simple, non-black background will help your dog stand out. In the image above, the brown wooden fence and greenery are a nice contrast to Jack's fur.
So next time your dog mysteriously turns into a black blob in your camera, look for ways to get more light on him/her.
