• Histogram – Image histograms is another technique or technology in which a histogram plots the number of pixels in the image (vertical axis) with a particular brightness value (horizontal axis). The algorithms in the digital editor allow the user to adjust the brightness value of each pixel and to dynamically display the results as adjustments are made.
• Gamma Correction – Gamma correction is a technology that is particularly useful for bringing details that is hard to see on most computer monitors out of shadows, In some image editing software gamma correction is called “curves” usually a tool found in the color menu.
