I have to say first of all that I love both color and black and white images pretty much equally. I love color images because color shows us everything we need to know, the color of hair, clothing, trees, eyes, etc. And color can look so beautiful in a large image on a wall.
But I also love black and white. It brings out the simplicity of an image, the simple emotions and the simple things that are happening in that moment. It is also great to use black and white for images with distracting backgrounds or clothing. I also love black and white as it reminds me of old family photographs. I have boxes of them and never tire of looking through them. A large black and white print or canvas on a wall looks great too.
Here are some of my favorite black and white images from pet and family portrait sessions.
