Adrenaline Broadcasting Teaches Photography Basics
Effective, quality photography is something we pride ourselves on here at Adrenaline Broadcasting. Good photography is one of the creative services we offer and is key in getting you high-quality marketing and social media content. Subsequently, we list some basic photography skills in our newest blog post. The succeeding basics are for those who use a DSLR camera, a micro four-thirds camera, or at least a camera that allows the photographer to adjust the shutter speed, aperture and ISO (image sensitivity).
Exposure: this term means the brightness or darkness of a photo. It seems simple enough to take a photo that is correctly exposed (has the proper brightness or darkness), but in reality, it can be quite tricky. Exposure uses things such as shutter speed, ISO and aperture in conjunction.
Aperture: this is the hole within your lens, through which light travels into the camera body. When you hit the shutter release button of your camera a hole opens up that allows your camera’s image sensor to catch a glimpse of the scene you’re wanting to capture. The aperture that you set impacts the size of that hole. The larger the hole the more light that gets in and conversely the smaller the hole the less light. Aperture is measured in ‘f-stops’. Moving from one f-stop to the next doubles or halves the size of the amount of opening in your lens (and the amount of light getting through).
F-Stop: this is a camera setting corresponding to a particular f-number. The f-number of an optical system such as a camera lens is the ratio of the system’s focal length to the diameter of the entrance pupil. This number is a numerical measure of lens speed and an important concept in understanding photography.
Shutter-Speed: this is the amount of time that the shutter is “open.” In film photography it is the length of time that the film is exposed to the scene being photographed and similarly in digital photography, shutter speed is the length of time that the image sensor views the scene you’re attempting to capture. Shutter speed is measured in seconds, or in most cases fractions of seconds. The bigger the denominator the faster the speed (subsequently, 1/1000 is much faster than 1/30). It is typical to use faster shutter speeds, such as 1/60 or higher. This is because anything slower is very difficult to use without getting camera shake.
ISO: this is how sensitive your camera is to incoming light. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The “image sensor” is the part of the camera that can actually alter sensitivity. With increased sensitivity, your camera sensor can capture images in low-light environments without a flash. But higher sensitivity comes at an expense as it adds grain to the pictures.
