Adobe-Part 3

Working with multiple images

The tile feature allows you to view a number of images together and edit them. To tile the images, in Photoshop 7, open all the images you require and then select Window > Documents > Tile; In Photoshop 6, go to Windows > Tile.
The images are arranged in Tile format, and you can toggle between them, using [Ctrl] + [Tab].

How to get an undo after few days

By default, the history feature lets you undo the last 20 actions. The next time you want to apply a tonal change, such as brightness or contrast, you don't have to go to the menu. Instead, you can choose them directly from the bottom of the Layers palette, by clicking on the New Fill or Adjustment Layer icon-the little black and white circle. A menu pops up. Here, you can choose the tonal change you want to apply. When you do this, a special layer appears in your Layers palette, with the name of your tonal change-such as Color Balance. The next time you open the file, the Color Balance layer will still be there. Just double-click on it, to edit your original colour balance adjustment.

Actions speak loud

Photoshop 7 has a new feature called Actions. An action is a series of commands that you play back on a single file or a batch of files. For example, if there is a folder of images that you need to convert to Web graphics, then you can do so with the help of Actions.
You can download actions for Photoshop 7 from the Net, but make sure they have the .atn file extension, or Photoshop may not be able to recognise them. Then go to the Actions palette and in the palette's drop-down menu, choose Load Actions. Now locate your action and click OK. The action will appear in the Actions palette under its own section from where you can run it.

You can even create your own actions, but these, by default, run so quickly that you might not be able to track a missing or wrong step. To slow down, or to put a pause between each step, go to Actions > Options > Play your action. Choose the 'Step by step' option. As an alternative, enter the number of seconds for which you'd like it to pause, from the Action palette while creating an action.

Image Modes: RGB, CMYK, Duotone, Tritone

Before you begin editing an image, save it in RGB mode for the Web, and CMYK mode for printing. You can also save image as Duotone (two colours) or Tritone (three colours). These modes impart interesting effects to an image. If you want to use an image for both Web and print, make sure that you have copies in RGB and CMYK mode.

Perspective in cropped images

The new Cropping tool in Photoshop 7 can now skew the cropped image-just select the Perspective option in the Options bar. You can even resize the cropped image by expanding the cropping edges beyond the image size. Use the [Alt] key to maintain the centre and the borders when you click, and drag the mouse. Use [Shift] to maintain the proportions.

Removing Noise from digital Camera images

Images taken from digital cameras show noise, when opened in Photoshop, usually in the Blue channel. To correct this, go to the Channels palette, and activate the Blue channel. Next, go to Filter > Blur, click Gaussian Blur, and add a slight blur to the image. Start with 0.5, and increase the blur by using the up arrow key. When the noise has pretty much disappeared, click on the RGB composite channel, and continue with the regular image correction.

Fixing Stray Pixels

Often, when using the Magic Wand or Color Range, some stray pixels are left unselected. To select these, go to Select > Modify > Smooth, enter a sample radius of 1 pixel and click OK. Now you won't have any of those stray pixels left behind.

Making a dull image brighter and sharper

Need to make a low-resolution image sharper and brighter? Duplicate the layer, which has your image and go to Filter > Other > High Pass. Retain the edge details in the specified radius where the sharp colour transitions occur, and suppresses the rest of the image. A radius of 0.1 pixels keeps only edge pixels.

The filter removes the low-frequency details in an image, and has an effect opposite to that of the Gaussian Blur filter. In the example shown here, the radius is set to 2. Select the Preview option and change the radius value, according to taste. Now, in the Layer's palette, choose the Hard Light option under Blend Modes. You can further flatten the image by choosing Layer > Flatten Image and see the difference between the new and the original image.
