Details and Textures
As mentioned earlier in the book, textures are a very important part of grayscale, seeing as they emerge to the forefront when there is no color present to take away the eye of the viewer from them. Also important to note that while soft and smoky monochrome images are attractive in their own way, they lack significantly in one of the foremost aspects of black and white photography, namely textures and details.
The general rule of thumb here is that the less the image is exposed, the more the fine textures and details will reveal themselves. You may even be surprised at how many intricate textural details you can bring out in a particular picture, by simply converting it into black and white, or shooting in black and white in the first place. While this is simply a lacking on the part of the human eye to see fine textures when the photo is in color, it can also be attributed to some of the textural blending that is often done when lush colors are employed.
Texture and detail, while different in a way, are somewhat connected in black and white photography. When we talk about texture, we are in fact talking about the amount of detail that appears in our images. That detail, in the form of texture, could be anything, from the freckles on a person’s face to jagged rocks and boulders on a cliff side, to a carpet of trees in a deep valley. As long as there is an ample amount of textures, it will produce a very powerful effect, especially when coupled with low exposure.
