Most digital images require some sharpening. However, an image that is too de-saturated (without actually being entirely grey) can lack impact unless it's done for effect. Cameras have printers licked when it comes to colour, particularly when it comes to vibrant colours (to put it more technically, cameras have a larger colour gamut than printers). Images that are too saturated are also harder to print accurately. However, the more saturated colours are in an image, the more cartoon-like an image will become. As with contrast, there's no right or wrong answer to how saturated colours should be in an image it largely depends on how you want your images to look. Landscape mode often boosts the saturation of greens and blues for instance. Some image controls often increase saturation on certain colours but leave others alone. The less saturated a colour is the closer to grey it is. The more saturated a colour, the more vivid it appears to be. That said, in flat lighting (such as when shooting in mist) a boost in contrast will add bite to an image.Ĭolours look overcooked when saturation is high (left), more pastel-like when saturation is reduced (right) If you plan to adjust your Jpegs in postproduction, it will pay not to boost contrast too much in-camera. It's easier to add contrast to an image later than it is to remove it (at least without having a detrimental effect on image quality). Low contrast images can look flat and quite frankly a little bit dull. Of the two, high contrast images have greatest impact. A low contrast image would see the values of the darkest and lightest parts close together. The highest contrast image possible would be one in which pixels in the image were either black or white, with no value in between. The greater the difference, the greater the separation between the two. High contrast images (left) have more impact than low (right), though too much contrast looks unrealistic.Ĭontrast is the difference between the darkest and brightest areas of an image. What do these options mean and how do they affect an image? Read on you if want to find out more. Typically there are at least three options: contrast, saturation and sharpness (though again the actual wording varies). This gives you the greatest say in what your Jpeg images look like when they're saved. However, the most interesting is the option that allows you configure your own image control. There are often different image control options such as Landscape or Portrait. Sony use Creative Style for their system. One of the things it does is apply the currently set image controls to determine how the Jpeg is processed (what these controls are called varies between camera systems, Canon use Picture Style, Nikon use Picture Control etc.). The fundamental difference between the two is that the camera doesn't really do anything with the image data in the Raw file but it does quite a bit to the Jpeg before it's saved. Either the camera saves the image as a Raw file or as a Jpeg. When you shoot a photo on your camera one of two things happen. Taking Control of Contrast, Saturation and Sharpness is at the very heart of photography. Taking Control of Contrast, Saturation and Sharpness
