How to Use Adobe Photoshop Cs3

Each evolution of Adobe Photoshop has improvements that not only make the photographer's work easier, but also better. Photographers and graphic designers have had input in the process. Photoshop Creative Suite 3 has two versions, regular and extended, the latter designed for higher-level users. The regular version, however, is packed with innovative tools. This article will help you learn how to use Adobe Photoshop Cs3.
Difficulty: Moderate


Open a digital photo in Cs3. Save a copy of the photo with a different name because you will want to work on the copy without touching the original. First, tone the photo to your preferences. You can use presets.
Go to Image > Auto Tone, Auto Contrast or Auto Color. For most evenly exposed photos, these presets will do a serviceable job. For more dynamic variation than the presets, open the "Info" box. Go to Window > Info. This palette will show you the percentages of each color as you move the mouse around the photo.
Go to Image > Adjustments > Levels. Below the "Options" button on the right are three eye droppers for, from left, blacks, midtones and whites. Select the black eyedropper and find the darkest area of the image. The Info palette will show you light to dark ranges for red, green and blue or cyan, magenta, yellow and black (K). The higher the number of K, the more black there is in that area of the image. Using the black eyedropper, find the blackest area of the image and click. Then click the white eyedropper and find the whitest area. This will be close to zero on the Info palette. When you find it, click it. This generally will give a balanced tone, but you can tweak it with the sliders under the histogram graph. The left one is black, middle is midtones and right is white.


Use "Shadow/Highlights" or "Curves" to tweak the tone further. If the image has stark contrast and some of the detail is lost, "Shadow/Highlights" will punch up the shadows without touching the highlights, or vice versa. With "Curves," you set a brightness in the center, then tweak the lights and darks on the sides.
Other controls under Image > Adjustments, such as "Brightness/Contrast," "Exposure" and "Variations" also allow manipulation of tone. "Variations" is not as subtle as some of the others, but you can compare variations of the image with different colors added or subtracted to the image.


Resize your photo depending on how you intend to use it. For example, an image intended for a website only needs a resolution of 72 dots per inch. If you plan to print the image, it should be at a minimum of 200 dots per inch (dpi). The more dpi resolution you choose, the finer the quality of the final image, but the bigger the file. To resize an image to 8 1/2-by-11 inches, go to Image > Image Size. In the pop-up menu, use the bottom portion. If it's a horizontal or "landscape" image, set the width to 11 inches. The height will reset automatically. Then go to "Resolution" and set it at 300 dpi.


Print the image. Go to File > Print. In the pop-up menu, select the printer and make adjustments. The default is for a vertical ("portrait") image, so if you need horizontal, click that button next to the "Page Setup" button. You will see how the image will look when printed. Click "Print." A pop-up menu will appear where you can set specifics for the printer. These settings will produce the best image on any paper. For a photo, choose a top-quality photo setting.


Experiment. There is a lot more to Photoshop than just toning photos. Go to Window > Actions for some presets. Try "Soft Posterize," "Sepia (Layer)" or "Fluorescent Chalk." You also can try things in the Filter Gallery (Filter > Filter Gallery). A photo can look like a painting. You can make it into "Stationary" or use "Chrome" or "Bas Relief."
