Viewing images in these galleries depends on good monitor hygiene. Please click the first image. Your computer screen should be able to discern every level of gray in this image, seeing all 30 levels on the top and a continuous, unbroken bend on the bottom. Use your monitor adjustment controls to tweak your viewing surface in order to get the greatest benefit from these images. But please do not be surprised if you are using a so so LCD. LCD is lack of black details. If you are really serious about the grey scale, please use this gamma calibrator to set correct black & white points for your monitor.
