When you need to learn in photoshop

By David Peters

The spot healing brush made its debut in Photoshop Elements 3, but now an enhanced version of it is available in Photoshop CS2. The spot healing tool is different from the existing patch and healing tools in that it does not require you to make a selection or define a source point before using it.

To begin, open your Photoshop program, then hold down Ctrl-Alt-Shift in Windows or Command-Option-Shift for Mac OS. This restores the default preferences. Click on "Yes," which resets, and then close the screen. Open an image file inside Photoshop, then make a duplicate layer to work on. This is one of the best habits you can develop for working with Photoshop; once you're used to editing only on a copy of the original, you will see that it's easy and worth it.

You'll see a variety of preset gradients displayed, from the default Foreground to Background gradient to the more complex Chrome gradient. All these preset gradients can be edited to create new gradients. You'll notice that some gradients have more colour 'stops' than others; the Foreground to Background gradient has two colour stops - black and white - while the Spectrum gradient has seven colour stops. You can modify a gradient by changing the colour of the stops - simply click on one and choose a new colour from the Color Picker. Alternatively, click on an image and sample a colour for your customised gradient using the Eyedropper Tool.

Image Adjustments: No doubt you'll need to tweak things such as levels and colour values on occasion. These shortcuts will take you to the heart of the Image - Adjustments menu - Adjust Levels.......[Ctrl]+[L] - Auto Levels.........[Shift]+[Ctrl]+[L] - Auto Contrast.......[Alt]+[Shift]+[Ctrl]+[L] - Auto Color..........[Shift]+[ Ctrl]+[B] - Curves ..............[Ctrl]+[M] - Color Balance.......[Ctrl]+[B] - Hue/Saturation......[Ctrl]+[U] - Desaturate..........[Shift]+[Ctrl]+[U] - Invert..............[Ctrl]+[I] File Management: Browse, open, close and save your files for a variety of formats, all at the touch of a key or three - New File.............[Ctrl]+[N] - Open File............[Ctrl]+[O] - Open File Browser....[Shift]+[Ctrl]+[O] - Save.................[Ctrl]+[S] - Close................[Ctrl]+[W] - Save As..............[Shift]+[Ctrl]+[S] - Save for Web.........[Alt]+[Shift]+[Ctrl]+[S] - Undo last action.....[Ctrl]+[Z] - Step Forward.........[Shift]+[Control]+[Z] - Step Backward........[Alt]+[Ctrl]+[Z] - Page Setup...........[Shift]+[Ctrl]+[P] - Print................[Alt]+[Ctrl]+[P] - Print with Preview...[Ctrl]+[P] - Print One Copy.......[Alt]+[Shift]+[Ctrl]+[P] - Jump to ImageReady...[Shift]+[Ctrl]+[M]

Photoshop offers blending options unsurpassed in the design industry in your "Layer Style" dialog box, you will first find "General Blending" options, which are often enough for any task. Experiment with the Blend Modes and their opacity to see just how incredibly flexible the normal Blending Options can be. To find your advanced blending options in Photoshop, double-click a layer or click the "Add a Layer Style" icon at the bottom left of your Layers palette, and then choose "Blending Options." Your "Layer Style" dialog box will appear. At the bottom of the Layer Style box, you will find, under "Advanced Blending," something called the "Blend If" tool. What is the Photoshop "Blend If" tool, exactly? Blend If is a "smart" blending tool. You can use it to blend images or create a more transparent image with almost infinite precision. This one tool is so flexible and handy it behooves any serios Photoshop designer to learn to use it, and use it well.

Like Adobe Remix, the hosted Photoshop service is set to be free and marketed as an entry-level version of Adobe's more sophisticated image-editing tools, including Photoshop and Photoshop Elements. Chizen envisions revenue from the Photoshop service coming from online advertising. "That is new (for Adobe). It's something we are sensitive to because we are watching folks like Google do it in different categories, and we want to make sure that we are there before they are, in areas of our franchises," Chizen said. Chizen described the introduction of Adobe Remix and the forthcoming hosted Photoshop as part of a larger move toward integrating hosted services into the company's product mix.

Your "Color Balance" and "Channel Mixer" are also valuable tools for transforming colors in an image. Find them both by clicking Image, then Adjustments. Inside your Photoshop Tool Box are all the icons you need to polish up an image to perfection. (If you don't see your Tool Box, click "Window" and select "Tools.") Almost every tool provides other hidden options, which become visible upon right-clicking. If you hover over the tool icons a message appears describing their function. Midway down on the right-hand column is the Dodge-Burn-Sponge tool. Try opening the "Sponge" function (you will probably have to right-click to find it). Under your top menu, you'll see the sponge icon appear, with various options. Click on the pull-down Mode menu and choose "Saturate. - 16890
