Histogram Anatomy Fa OSD paraneters per Visual settings The horizontal component of a histogram runs from 0 to 255 What is E i Scripting paraneters am Miscellaneous stuff important to understand is the 0 and 255 are not values they are labels representing a color value When you see a line in the middle of the histogram label 1277 it s saying this is how many 127 s there are in the image The vertical component of a histogram is the count of pixels at a given level The bottom is zero and the top represents the largest count of values for a label So if you have a 7MP image and every color is 1277 then the top of the histogram represents 7 million pixels EEE EL REN RGB Histogram RGB histograms simply count pixels at each level The RGB histogram of an image of three boxes red green and blue where every color has a value of 127 would be a single line in the middle of the histogram at label 1277 Luminance Y Histogram Luminance histograms attempt to factor in the perceived brightness of colors A luminance histogram of an image of three boxes red green and blue where every color has a value of 127 will show three lines at labels 38 red x 0 3 75 green x 0 59 and 14 blue x 11 Show live histogram Don t Always Shoot e Don t Don t show histogram on LCD e Always Always show the histogram on the LCD e Shoot Only show the histogram when shut

39. While use of RAW formats avoids the compression artifacts inherent in JPEG fewer images can fit on a given memory card Post processing every single image is also a chore that not many amateur photographers and some professional photographers enjoy doing This means that for most practical purposes amateur photographers will find that saving in RAW is not an interesting option and that shooting in JPEG is more than sufficient Unless You are unsure of the white balance to use or need accurate colour reproduction of a subject or you want optimum control over sharpness contrast saturation Many photographers are finding that they do want the control that RAW gives them With some cameras and also with CHDK you can have the advantage of saving RAW and JPEG this means having the option to just keep the RAWs that you need for optimum processing or otherwise just keeping the JPEGs if you are pleased with the camera s processing For many saving in JPEG is more than adequate JPEG files are compressed and compared to RAW they are smaller save faster and more images can fit on a memory card Many professional photographers shoot at the highest JPEG image quality Remember also RAW can be disabled for certain shooting conditions see the RAW parameters menu for Disable RAW burst etc There is no single RAW format formats can be similar or radically different Different manufacturers use their own proprietary and typically undocu
