In today's lesson, I have increased my knowledge based around my role for IEA(Product technician) by learning about the exposure triangle and all of its aspects. As a whole, exposure is the measurement of the amount of light which is absorbed when taking a photo. This can be differed by ISO, Shutter Speer and Aperture.
ISO
ISO is the sensitivity of the image sensor to light while taking the photo. The higher the ISO, the finer the grain of the image, the lower the ISO, the photo is seemed to look fuzzy or grainy. Usually, photographers take low ISO images in areas with little light because with low ISO, it can absorb more light due to the increased sensitivity.
Shutter Speed
Shutter speed is the the amount of time the camera shutter is opened while being exposed to light during taking photos, shutter speed is usually used to capture object in motion or motionless. The higher the shutter speed, the more motion is seemed to be captured, the lower the shutter speed, the more it seems to make the object motionless
Aperature
Aperture is the stage before ISO. Before ISO happenings, there is a lens that can change its size which affects the amount of light that reaches the sensor. The higher the aperture, the lower the depth of field, the lower the aperture, the lower the depth of field. Depth of field means the focus range of the image meaning more of the background is captured, this is a wide depth of field and narrow depth of field means that less background is captured but the foreground is the main target of the image.
