Next from the Blending modes drop down menu (top left and usually set on Normal), choose the Multiply option. Immediately, you’ll notice that all the white highlights are dropped from the photographic image layer, becoming as bright as the underlying paper layer. This will introduce an unexpected contrast change that you will next need to address using your Levels dialog. Most images will appear darker and muddier after a Blending mode change, so to increase image brightness, move your midtone slider to the left. Don’t overdo it, as you don’t want your image to look too light. This illustration shows Normal Blend on the left and Multiply blend on the right. Low contrast alternative: Many carbon tissue prints were made purposely to look very pale and delicate, a bit like deliberately underexposed low contrast photographic prints. You can further modify the digital process by adjusting the image contrast at the final stage by manipulating the little used Levels Output sliders. Found at the base of the Levels dialog box and with only two sliders for highlight and shadow, these two markers effectively determine the starting points of both contrast extremes. Unless you decide otherwise, all digital images will be ranged in brightness from white 255 to black 0, but by modifying the Output values you can have your highlights starting at a light grey 200 and your shadows ending at a weak grey 30. By far the easiest way to change your image to a low-contrast version is to drag the sliders towards the centre until you’ve achieved the desired effect.
