Photoshop 1.3 [curves]
- Begin by opening Adobe Photoshop CS3. Using the File>Open command, open the photograph you would like to adjust.
- Select Layer>New Adjustment Layer> Curves.
- The New Layer dialog box will appear. Give your layer a name and select “Ok.”
- In the Curves dialog box, you will see the pixels in your image being represented by a diagonal line running from the bottom left corner (black) to the upper right corner (white).[premium content]
- You can adjust the curvature of the line by clicking on it, which adds a control point, and then dragging the control point. Adjusting the curvature of the line allows you to add lightness or darkness to a specific part of your image.
- Moving the control point into the yellow area shown above (below the original diagonal line) makes that part of the image darker. Moving the control point up (the white part of the image) causes that part of the image to get lighter.[premium content]
- If you would like to make the sky in your image darker, you can move your mouse over the image (an eye dropper will appear) and click on the part of the image you would like to change (in this case the sky). You will now notice a circle appears on the horizontal line in the curves dialog box in the location on the line that controls the lightness/darkness of the sky. Hold down the Ctrl key (Command on Mac) and click to add a control point to your horizontal line.
- Dragging the control point down (into the yellow zone on the image above) causes the sky to darken. Doing the same for the building (but dragging the control point up to lighten it), you end up with a traditional S-Curve which many photographers use to enhance/diminish contrast in an image.
- Once you have finished, click “Ok” You will notice a new adjustment layer above your original “background” layer which applies the effect you just specified on the layer below it. You can turn off the adjustment by clicking on the eye icon next to the layer in the layer stack.
- Now, save your image as a .psd file (this will preserve editing capabilities).
- If you wish to save your image for the web, follow Photoshop 1.6 [save for web].
