In the same location in Tools, the Quick Selection Tool offers fewer controls but does an even more intelligent job. Two check boxes give you control over how the Magic Wand tool behaves Tolerance (which defines the range of related values away from the sampled color that will be included in the selection – based on 256 levels) and Contiguous (which limits a selection to areas of similar color that abut one another). The Magic Wand, found in the Tool Bar, is ideal for selections of broad areas of color. Once the contour has been defined, you can throw away the adjustment layer that was only intended to be used to make selection easier. If contrast helps define a contour then you can accentuate the contrast of any one component of color within an image to make it easier to define a contour, using an adjustment layer. Contrast in any one component of color can be used – luminosity (light and dark), hue (warm and cool), or saturation (intense or desaturated). Keep in mind that all of these techniques use contrast within an image to isolate a contour. But it’s highly advantageous to have the option of doing so when you need to.īesides defining an area by hand, either with a selection or brush tool, there are a number of more efficient and precise ways to isolate contours the Magic Wand Tool, the Magnetic Lasso Tool, the Color Range feature, and deriving a contour mask from a contrast mask. Just because you can define contours precisely, doesn’t mean you should. What’s more, many times, photographers simply need to define broad areas to work in with smooth transitions into surrounding areas. Remember, contours in continuous tone images are often quite soft. Once you learn a few essential selection and masking techniques, few contours will elude your grasp.īefore I continue, let me caution you against always defining contours precisely. What was once extremely tedious and challenging is now quick and easy. A complex contour mask – made one minute.ĭigital imaging offers the ability to define complex contours efficiently and precisely, enabling users to affect an image in very specific areas.
