WebApr 28, 2024 · Aperture is probably the first thing most photographers think of when they want to adjust the depth of field. Large apertures, which correlate to small f-stop numbers, produce a very shallow depth of field. On the other hand, small apertures, or large f-stop numbers, produce images with a large depth of field. WebInstead of being spatial and having three dimensions like the spatial representation of an image: width, height, and intensity; instead a histogram is two dimensional, having only the attributes of intensity and volume. Before we delve into reading details about noise and exposure and such from a histogram, it’s best to understand the basics.
