Oct 2, 2023 · Compositional Rules. “The Rule of Thirds” is a simplified method to frame the main subject to create eye-pleasing balance in a resulting photograph. In all honesty, The Rule of Thirds is meant to encourage beginners to break free from centering all of their subjects. Most people have heard of The Rule of Thirds.
Oct 20, 2022 · In fact, there are even more math formulas used in photography, and some of them are used in the manufacturing process, too. The goal of this article was to see if mathematics is a crucial part of photography, and it is. Luckily, an average user and even professional photographers don’t have to do any math when taking a photo.

A stop in everything but photography is coming to a complete halt. No movement. No motion. Photographically, a stop or more accurately an f/stop is a quantity of light. F/stop, by itself, always refers to an aperture value of a lens. F/8.0 is an aperture value. F/stops are used in relation to an amount of exposure to describe how much more light or...
F/stops originated with a lens’s aperture. The f/stop is a ratio between the focal length of the lens and the diameter of the aperture opening. This is more than you want or need to know. Simply put, increasing the amount of light by one stop or f/stop doubles the areaof the aperture. An aperture of f/5.6 is twice the area of one of f/8.0. The rati...
This is where rough patches in understanding photography happen. Each of the three sides of the exposure triangle, shutter speed, lens aperture and ISO, honor the doubling and halving of f/stop. Whether the amount of light is adjusted and in which direction — double or half — is where confusion creeps into understanding.
The hole light passes through inside a lens is called the aperture. Changes are indicated in f/stops. Like most things in photography, the numbering system seems a bit backward. F/2.8 lets in a lot more light than does f/16. The chart below shows some aperture openings with their corresponding f/stops. F/2.8 is a much larger opening than f/16. An a...
Shutter speeds either cuts the time light strikes the sensor or increases the timelight strikes the sensor. Here are the possibilities. 1. A shutter setting that reduces the time the light shines on the sensor by one f/stop is two times or twice as fast as the shutter speed before it. 1.1. The shutter speed is two times faster so the exposure is 1....
ISO is a number that describes the sensitivity of the sensor to light. The higher the ISO, the more sensitive the sensor becomes and the less light it requires. As the ISO doubles, the amount of light needed drops by half. 1. With ISO 400 set on the camera, the exposure is 1/125 at f/8.0 1.1. ISO 800 doubles the sensor’s sensitivity so the sensor n...
You have already noticed the numbers between the full ISO numbers in the chart above. Those are 1/3 of a stop. I saved this part for last so you wouldn’t get too disheartened. Your camera came set to display exposure in a third of a stop step. Don’t worry about learning all the numbers between the full stops. It’s just how photography works, it’s t...
Exposure is a matter of doubling or halving the amount of light. That’s it. Refinement is in thirds. Learn the full stops of apertures from most light to least light, the shutter range of your camera from most light to least light and understand the ISO numbers. Smaller ISOs require more light and produce less noise. Higher ISOs require less light ...
Apr 10, 2023 · Photographers also use mathematics to manipulate photography in order to create stunning visuals that capture the beauty of their subjects. This includes concepts such as focal length, depth of field, and aspect ratio. In summary, mathematics is an integral part of photography as it helps photographers understand numerous aspects of the art.
Aperture diameter = 50mm (bigger, more light through) F-number therefore = f/2. Imagine you cut a pizza into 10 slices. 1/2 of the pizza is way more than 1/10 th of a pizza, which would be just one slice. Inside your lens, it works the same way, and f/2 lets in way more light than f/10 – as seen in the example above.
May 4, 2023 · Depth of Field (DoF or DOF) The depth of field is the amount of your image that is in sharp focus. It is affected by two things: The aperture chosen (smaller aperture = more depth of field) The distance to the subject. Here are two extremes as examples. ISO 160, f/22, 0.3sec.
