... Color . Selections . ... Modifying Selections . ... Magic Wand- selects part of an image based on the similarity in color of adjacent pixels. ... Enter a value in pixels, ranging from 0 to 255. A low value selects the few colors very similar to the pixel you click. A higher value selects a broader range of colors. ... Otherwise, all pixels in the entire image using the same colors are selected. ... Select a sample color and than the add sample dropper to refine your selection. ...

To change the Scaling Function (how pixel values are binned into color levels): . ... For example, the basic grey-scale color map specifies no intensity for any color at the lowest color level, full intensity for all colors at the highest color level, with the red, green and blue intensities varying linearly for intermediate levels. ... At low bias, low color levels (i.e., low pixel values) will have non-zero intensities, while at high bias only high pixel values will have non-zero intensity. ...
