Editing Images with Adobe PhotoDeluxe 2.0

Note: Instructions are provided here Adobe PhotoDeluxe 2.0, but these functions are similar for most good image editing programs.

Your image file must be open to complete the following procedures. Open the image by starting the image editing program, pull down the File menu and select Open. Then navigate to your digital image and open it. Or, or can drag the icon for image and drop it onto the icon for the image editing program (PhotoDeluxe).

Once your image is open in PhotoDeluxe, click on the Advanced button in the upper left.

Changing the Image Resolution
Remember, the image resulution is the number of dots per inch. For images that are for screen display (web images), there is no need for them to have resolution higher than 72 dpi.

Note: You may notice that your image now looks smaller, especially if you reduced the dpi. When an image is displayed on the computer screen by PhotoDeluxe, it is shown at 72 dpi, assuming that it is being displayed at 100% magnification. You can change the magnification of your images by clicking the "+" or "-" buttons at the top of your image window. This can be confusing because PhotoDeluxe always displays images at 72 dpi. So Even if the dimensions of the image are 1 inch X 1 inch, it will look larger in PhotoDeluxe if the resolution is higher than 72 dpi.

Note: You can undo any change that you make by clicking on the Undo button at the top of your image window. Keep in mind, however, that you can only undo the last change that you made.

Changing the Image Size (dimensions)
As stated above, you can change the size that the image is being displayed (Which does not affect the file size, or how it prints, or how it displays in a document), click on the + (plus) or the ­ (minus) buttons. But this does not really change the image dimensions. More importantly to actually change the physical dimensions of the image (which affects the file size), click on the Size tab, then click on the Photo Size button, then you can type in new dimensions at the bottom of the dialog box. Be sure that the Proportions checkbox is selected at the bottom (if you don't constrain the proportions, your image will get stretched out of proportion). Also, be sure that the File Size button is not selected, so that your file size can grow or decrease as you change the image size. If this box is selected, the resolution of the image will change as you change the dimensions, keeping the file size the same.

Note: If your image was originally at 72 dpi, you cannot make it any larger without a decrease in quality (you would be stretching those pixels large enough to see, which looks bad).

Note: There is rarely a need for images larger than 3 or 4 inches (200 to 300 pixels) on a web page. Keep in mind that the smaller the images, the smaller the file (faster download time).

Sharpening the Image
Click on the Quality tab, then click on the Sharpen button. If you want to sharpen more, click on the Sharpen button again (but note that you can only Undo the last change that you made!).

Adjusting Levels of the Image
Adjusting levels is includes brightness, contrast, color balance, etc. these can all be adjusted seperately, but usually you can do an "Instant Fix", which will automatically adjust all of these parameters.
To do an Instant Fix, click on the Quality tab, then click on the Instant Fix button. If you do not like the results, click the Undo button.

Converting Images to the Desired Format
Remember, for web pages, you will use GIF images or JPEG images. GIF's are best for logos or cartoons with few colors, JPEG's are best for photographs.

While the image is open, click on the blue Send button in the upper left. Then click on the To Disk tab, then click on the Export button, then on the Export tab.

For GIF images: If you want to save your image in the Gif format, click the Gif Format button. In the window that opens, click the Advanced button. In the pulldown menu next to Palette, select Adaptive. Under this, next to Colors, pull down the small menu and select a smaller number (start with the smallest, 8). Then check to see if the image looks okay at this setting by clicking the Preview button. If the preview shows that the image quality is not acceptable, close the preview window and select the next larger number of colors. Continue this until the quality is acceptable, then click OK to go to the window that allows you to name the file and designate the location to save it. Give it a short name, with the .gif tag at the end (such as picture1.gif).

For JPEG images: If you want to save it as a JPEG, click the Other Export button. In the dialog box that opens, pull down the menu next to Format and select JPEG. Give it a short name, with the .jpeg tag at the end (such as picture1.jpeg), designate the location to save it to, then click Save. In the small window that opens, click the Options button. In the pulldown menu next to Quality, select Low, then click OK. You can select medium or high, but this will make the file size much larger. Only do this if the resulting image quality is unacceptable.
