ISO – a way to brighten your photos if you can’t use a longer shutter speed or a wider aperture.In photography, aperture is typically expressed in “f” numbers (also known as “focal ratio”, since the f-number is the ratio of the diameter of the lens aperture to the length of the lens). If the aperture is very small, the depth of field is large, while if the aperture is large, the depth of field is small. Aperture also controls the depth of field, which is the portion of a scene that appears to be sharp. The larger the hole, the more light passes to the camera sensor. Aperture – a hole within a lens, through which light travels into the camera body.
Slow shutter speeds allow more light into the camera sensor and are used for low-light and night photography, while fast shutter speeds help to freeze motion. Shutter speeds are typically measured in fractions of a second, when they are under a second.

Knowing how to adjust the settings of the camera when needed, helps to get the best out of your camera and push it to its limits to take great photographs. Thoroughly understanding how ISO, shutter speed and aperture work together allows photographers to fully take charge of the situation by manually controlling the camera. In many cases, the camera has to guess what the right exposure should be by evaluating the amount of light that passes through the lens. While most new DSLRs have “Auto” modes that automatically pick the right shutter speed, aperture and even ISO for your exposure, using an Auto mode puts limits on what you can achieve with your camera. Thank you for the opportunity to present our products and services.It is difficult to take good pictures without having a solid understanding of ISO, Shutter Speed and Aperture – the Three Kings of Photography, also known as the “ Exposure Triangle“. Please stop by any one of our ten retail stores throughout Virginia or explore our numerous online services.

Richmond Camera is also recognized as one of the best professional labs in the nation for quality, service, and professional results. Our goal has always been (and always will be) to provide excellent customer service while remaining on the cutting edge of photographic technology. We are only satisfied with the best equipment, products, and personnel. The founding philosophies live on in our processing laboratory and ten retail stores. Since that time, Richmond Camera has provided superior photofinishing services as well as an endless selection of products and equipment for nearly 70 years, making Richmond Camera the primary source for photographic supplies in central Virginia. Take your camera outside and start playing with this concept and you’ll quickly see the relationship between the numbers and the results you record.įounded in 1938 by James Bullard, the first camera shop in Richmond, Virginia was based on the simple premise of providing quality products, fair prices, and timely deliveries. Understanding the basic numeric structure of f-stops will further strengthen your ability to make adjustments based upon available light. For example, if you’re using a 50mm lens, f/2 is designating that the diameter of the aperture is 25mm, (50 divided by 25 equals 2.) The focal length of a lens is defined in millimeters. The f/1.4 setting lets in the most amount of light and f/22 lets in the least amount of light.

The standard scale of full f/stop range is as follows: Adjusting by one full stop will either allow in half or double the amount of light. Essentially, the number is calculated by dividing the focal length of the lens by the aperture diameter. The f/stop is known by several other names including the relative aperture, the f/number and the focal ratio (f/ratio). Let us help clarify the concept so you can better enjoy playing with your DSLR by getting out of auto mode. The reality of photography is that it includes a fair amount of mathematics, an aspect that can be both interesting and confusing. If you’re someone who wouldn’t know the difference between an f/stop and a bus stop, worry not, because it is a concept that stumps many starting shutterbugs.
