Hey Everyone! Here's another episode of Tez Tareen Tuesday. This time it's about the basics of some technical terms used in Photography. You will learn about Aperture (F-Stop), Shutter Speed and ISO. These are 3 important variables in photography. So first variable Aperture is basically the opening of a lens. So if Aperture is bigger in size, more light would be able to reach the sensor. But Aperture values are inverse that means if F(value) is smaller then aperture would be large and if F(value) is larger then aperture would be smaller in size. Aperture is also responsible for Depth of Field. So if we have bigger aperture then Depth of field will be shallow and if aperture size is smaller then depth of field will be deep. Second variable Shutter Speed is the duration that a camera sensor is exposed to light. Say if we have shutter speed of 1/50 that means shutter will open for 50th part of 1 second. Slow shutter speed can create motion blur while faster shutter speed will take sharp stills but needs more light. Third variable ISO is the sensitivity of the sensor. Higher ISO value can capture image in very low light but at the cost of noise. So if we need images without noise, then it is always recommended to take photos at low ISO value but for that we alwasy need good light.
