The Waveform Scope shows the luminance and RGB & YCbCr values for the image. Using the Histogram Scope, the user can evaluate whether the exposure is within the correct dynamic brightness and the color saturation range. For a properly balanced image, the histogram's peak value distributes evenly on the center of the X-axis, just like a normal distribution chart. If you connect all the pixel value points on the Y axis, it forms a continuous Histogram Scope.įor an overexposed image, the histogram's peak value will be concentrated on the right side of the X-axis conversely, for an underexposed image, the histogram's peak value will be concentrated on the left side of the X-axis. The higher the peak value, the more pixels there are for a specific brightness value and the larger area it occupies. The Y-axis represents the pixel intensity distributed throughout an image. Histogram Scope is composed of an "X-axis" and a "Y-axis." For the "X" axis, the graph's left side represents the darkness, and the right side represents the brightness. In the following article, we are going to introduce the standard functions for getting correct exposure.
#Exposure x buy professional#
For example, the Histogram and Waveform are handy tools for professional videographers. To assist videographers in monitoring image exposure, many DSLRs have built-in functions to monitor exposure.

Though users can use image-editing software to make adjustments in post-production, managing correct exposure can help the videographer get high-quality images and avoid spending excess time in post-production. "Exposure" is one of the essential skills for shooting videos. Have you ever looked at the LCD screen of a camera in a bright room and thought that the image was very dim or under-exposed? Or have you ever seen the same screen in a dark environment and thought the image was over-exposed? Ironically, sometimes the resulting image is not always what you think it will be.
