Choose the option ‘Flatten’ when the Warning dialog box appears.
Go to the Image menu and from the Mode submenu select ‘Grayscale’. Note the changes to the histogram by viewing the histogram in the Histogram palette. An effective way of expanding contrast in Photoshop Elements is to duplicate the layer and set the top layer to ‘Overlay’ blend mode. For this image to act as an effective displacement map the contrast must however be expanded. Dark pixels in the map shift the graphic pixels down into the shaded valleys of the 3-D form whilst the light pixels of the map raise the graphic pixels onto the illuminated peaks of the 3-D form.Ī silk dressing gown was photographed using the available light. The principle on which this technique works is that of ‘mountains and valleys’. How it works: The brightness level of each pixel in the map directs the filter to shift the corresponding pixel of the selected layer in a horizontal or vertical plane. The final effect can be likened to ‘shrink-wrapping’ the flag to the 3-D form of the undulating silk. The ‘map’ defines the contours to which the flag must conform. This can be achieved by using the Displace filter in conjunction with a ‘displacement map’. The highlights and shadows that give the silk its shape can however be further utilized to wrap or bend the flag so that it obeys the material’s shape and sense of volume.
By using the blend modes the flag in this project can be modified to respect the color and tonality of the undulating silk beneath it. The layer blend modes are an effective way of merging or blending a pattern or graphic with a three-dimensional form.
