Three of Dismukes' Photoshop masks

beach. He converted each path to a selection, saved the selection as an Alpha Channel, then saved each image as an RGB TIFF file, including the alpha channel. You can accomplish the same result in Painter. Open one of your source photos and use the Pen or Quick Curve tool (Tools palette) to draw a shape around the desired portion of the image. When you're done, choose Shapes, Convert To Selection; then to save the selection as a mask, choose Select, Save Selection. View the selection as a mask by opening its eye icon in the Masks section of the Objects palette. You should see your image covered by a red overlay-the default color for the mask. To view only the mask in black-and-white, click the RGB-Canvas eye icon shut in the Masks section.

Choose the Layer Adjuster tool and in the Objects palette, click the left triangle on the Layers section bar to open the Layers section. Then open each of the source images and choose Select, Load Selection and Alt/Option-click on each selection to make a layer. Loading the selection and making a layer prepares Painter to export the item from the source image with its mask. There are three ways to import source images into a composite file: Copying and pasting through the clipboard, performing a drag-and-drop, or using the File, Place command to bring the source image

in as a reference layer. To paste using the clipboard, select the layer in the source image with the Layer Adjuster tool, choose Edit, Copy, then make the background image active and choose Edit, Paste. If your component images are approximately the right size, the easiest way is probably to drag-and-drop: Select the layer in the source image with the Layer Adjuster. Now use the Layer Adjuster to drag the masked item to the background image. If you're working with large files, positioning and scaling can be accomplished much more quickly using reference layers. To import an image as a reference layer with a mask, save the source file in RIFF format (to preserve its mask), then choose File, Place, navigate to the source image and choose Open. In the Place dialog
