Adobe Photoshop CS6Photoshop BasicsStrategy for Retouching

BrightnessSkin retouchingColor CorrectionImage CroppingEye-Whitening Dodging / Burning SaturationResolution and Image SizeIn Photoshop, you can see the relationship between image size and resolution in the Image Size dialog box (choose Image>Image Size). Deselect Resample Image, because you dont want to change the amount of image data in your photo. Then change width, height, or resolution. As you change one value, the other two values change accordingly.

Resolution: 300 pixels / inchConstrain ProportionsStraightening and CroppingStraightening an image or selection with Free Transform. Edit menu in the Menu Bar along the top of the screen and choosing Free Transform from the list. keyboard shortcut Ctrl+T (Win) / Command+T (Mac) (think "T" for "Transform"). move your cursor just outside the bounding box. Youll see it turn into a curved line with a small arrow on either end. Youll see it turn into a curved line with a small arrow on either end. Then just click and drag with your mouse to rotate it. If you hold down your Shift key as you drag, youll rotate it in 15 increments (youll see it snap into place as it rotates):

Straightening and CroppingCrop Tool, either by clicking on its icon in the Tools panel along the left of the screen or by pressing the letter C on the keyboard.

Click on any of the handles and, with the mouse button held down, drag them around to resize and reshape the crop box. The area inside the crop box is the part of the image youll keep. Everything outside the box will be cropped away. Photoshop darkens the area outside the crop box so its easier for us to see which part of the image were keeping:

Adjusting LightnessTo access the Curves adjustment, click on the New Adjustment Layer icon at the bottom of the Layers palette, and select Curves from the list of adjustment layers that appears:

Select the little Hand icon in the Curves dialog box to bring up an eyedropper. You can use this eyedropper to hover over different areas of your image to get an instant display of where that exact point rests in the overall brightness/tone of your image on the Curves line. Click on that spot to drop a point, or click and drag up or down to brighten/darken. This can be a quick way of cleaning up frustrating or difficult areas of an image.

Adjusting SaturationIncreased Saturation

The Hue/Saturation tool can be found under the menu Image/ Adjustments/ Hue/Saturation. Or on the layers palette (accessible in Window/ Layers) click on the half white & Black circle and choose "Hue/Saturation." (The two layers in the image are adjustment layers).Complete DesaturationOriginal ImageRepairing Areas with Clone Stamp ToolThe clone stamp tool is located on your Photoshop toolbar. Keyboard Shortcut (S) for stamp.

Once on the Photoshop clone stamp tool, you can set your brush options (located at the top of the screen). Brush size and shape, opacity, flow and blending modes can all be selected. If you want to copy an exact area you will leave the opacity, flow and blending mode at their default settings and only choose a brush size and shape.

To select the area you want to copy from, move your mouse to the area you want to duplicate and Alt-click (Windows) or Option-click (Mac). The cursor will change to a target. Click the exact spot you want to start copying from.

Click and drag over the area you want to replace or correct and you will see the area you selected "cover" your photo. Play around with different brush settings and try replacing different areas of your photo until you get the hang of it.

Applying Unsharp Mask FilterThe main sharpening tool in Adobe Photoshop is the Unsharp mask, that is found under filter sharpen Unsharp mask.

Once you access the Unsharp mask filter, a dialog box will pop up. You can check and uncheck the preview image check box, checking and unchecking the preview check box would only apply the before and after effects on the image in the main window.

The amount slider controls the amount of sharpening you apply on the image. The greater the percentage, the heavier the sharpening effect. The lesser the percentage, the lighter the sharpening effect.

The radius slider allows you to control the thickness of the halo. It controls the amount of blur that is applied to the unmasked areas of the image.

Smoothing and Enhancing SkinThe healing brush tool is essentially a content-aware version of the clone stamp tool. If you control click on the a given area of the image to define the source and the click and drag anywhere else on the map, the tool will copy all the pixels at the defined location and paste them under your brush. The only difference between the clone stamp tool and the healing brush tool is that the latter blends the pixels into the new area instead of flatly pasting them over.

With the tool selected (Keyboard Shortcut J) Center the brush (the black circle) on an area of the face that's similar in color and texture to the wrinkled area. Press Alt (Option on a Mac) and hold. The cursor will change to a bulls-eye when your press and hold Alt (Option). Click to sample the area. Release the mouse button. Position the brush (the black circle) on the area of the photograph that you want to retouch. Click. The sampled area is blended with the photograph. Click the brush multiple times over the blemished skin. Its best not to click, but to hold, and drag the brush.

Skin color varies greatly, so resample often.

Making Eyes and Teeth WhiterWe can also use Curves to brighten the teeth and change their color. This method is particularly useful if you want to fine-tune the effect in more detail.

Using the Lasso tool, make a selection of just the teeth, then choose Image > Adjustments > Curves (Ctrl/Cmd + M). We need a white adjustment, so keep the Channel set to RGB and drag the top right corner of the diagonal line to the left as shown.

You'll notice that this results in a slight yellowing of the teeth. Blue is the complement of yellow, so pick the Blue channel from the Channel drop-down, Select the little Hand icon in the Curves dialog box to bring up an eyedropper. Click and drag the mouse up or down on the teeth to add or subtract blue till you achieve the desired color.

Select Blue from Channel Drop Down

Using the Quick Selection Tool

To begin selection, click once with the mouse. An initial selection outline appears around the area clicked on. To add to the initial selection, then, simply click and drag. The area dragged over is added to the selection. To select the Quick Selection Tool, click on its icon in Photoshops Tools panel, or press the letter W on your keyboard to select it with the shortcut:To remove an area from a selection, hold down your Alt (Win) / Option (Mac) key, which temporarily switches the Quick Selection Tool to Subtract from selection mode. The small plus sign in the center of the cursor will be replaced with a minus sign (-). Then, with Alt / Option still held down, click and drag inside the area you need to remove.Moving a Selected AreaTo move a selection, simply grab the Move tool (the four-headed arrow) at the top right of the Tools panel, and then drag the selection.

If youre moving a selection on a layer, youre left with transparent pixels. When you use the Move tool, your cursor icon changes to a pair of scissors, letting you know that youre cutting out the selection.Manipulating Sections SkewWith Skew selected, if you click and drag any of the side handles, youll tilt the image while keeping the sides parallel. Holding Alt (Win) / Option (Mac) as you drag a side handle will skew the image from its center, moving the opposite side at the same time but in the opposite direction:

DistortWith Distort selected, click on a corner handle and simply drag it around in any direction. Its similar to Skew but with complete freedom of movement. Holding Alt (Win) / Option (Mac) as you drag the corner will move the diagonally-opposite corner in the opposite direction at the same time (if you didnt already guess I was going to say that):

Using the Magic Wand ToolWith the tool selected and all of its options in the Options Bar set back to their defaults (Tolerance 32, Contiguous checked), click somewhere within the desired selection

Adding To SelectionsTo add to a selection, hold down your Shift key and click in the area you need to add. Youll see a small plus sign (+) appear in the bottom left of the Magic Wands cursor icon letting you know youre about to add to the selection. In my case, with Shift held down, click somewhere within the desired selection included in the selection initially:

Selecting with the Lasso ToolSelect the Lasso tool from the Tools panel. keyboard shortcut; (L)

Position the cursor somewhere on the edge of the element that you want to select.

The hot spot (the lead point) of the Lasso cursor is the end of the rope.

Trace around the element and try to capture only what you want to retain in your selection.

While you trace, a line forms that follows the movement of your mouse.

Dont release your mouse button until you complete the selection by returning to the starting point to close the loop. When you release your mouse button, Photoshop thinks youre done and closes the selection with a straight line from your endpoint to starting point

Refining the Edge of a SelectionSelect the subject from your photograph using Quick Selection Tool (W). Use the Add to Selection and Subtract from Selection buttons to make sure you select your subject nicely.

Within the selection, Right Click to bring up the menu bar and select, Refine Edge. Edge Detection. Here you need a small r
