Sharpen [other than in specific aresa for effect] and resizing, should be\nthe last.\nWorking on photographs, I prefer:\nSpotting [clone tool, etc]\nTonal adjust [Image adjustment tools]\nCropping\nFinal large area corrections [Brightness, Contrast, Curves]\nSave 'master'\nResize for specific use\nSharpen [if needed for smaller size appearance].\n\nIn the tool bar for the Clone tool you will see a box and the word\n"Aligned". If there's a check mark in this box, sampling point (x)\nwill move as the brush is moved.\nIf the box is unchecked, the sampling point will remain where you\ninitially set it.\nEach time you click ALT, you re-set the sampling point.\nIf you want to clone over an area using the same sampling point for\nthe entire area, make sure the box is not checked. For realism,\nthough, you probably won't want the same sampling point for a large\narea to be cloned. You'll want slight changes in color or texture.\nLeave the box unchecked, clone some area, and re-set the sampling\npoint in a slightly different place.\n\nthe new cs5 has an option where it can fill in those areas using the\nnew fill aware tool.\na manual crop with the marquee tool would do as you ask, i am not\naware of an auto one\n\nDouble click the background layer to make it a normal layer. Go to the\nChannels palette and click on the RGB icon while holding the Ctrl-key\n(Cmd-key on a Mac). That will load a selection based on luminosity.\nChoose the rectangular selection tool and while holding down the\nAlt-key, select the image itself. This will subtract the image from the\nselection, so you only have the shadow and he white background selected\nby luminosity. Hit the delete key to delete the selection.
