Most photographer’s problem on taking picture is flare, where the photographs seem washed-out with excess light. Usually, by using a clean, high quality lens , this problem can be minimized.
But the US chipmaker Micron has simpler, and cheaper, a solution - remove it from images after they’ve been taken. The idea is : Since flare is essentially the addition of white light across the entire image, the picture contrast and quality can be restored by simply subtracting the same amount of light from image. Then, what we need to do? The first step is to spot whether flare is present or not in a picture. This can be done by looking for the absence of deep black tones. If they are missing, the software assumes that flare is present, tries to assess how much flare there is and then subtracts this from the image. If deep blacks tones are then found, the picture is considered fixed. If not, the program removes still more white light from the image until, the blacks appear.
What do you think about this idea, then? Just tell me if you’ve been managed to get a flare-free photographs
