Adobe Photoshop


Adobe Photoshop is software written by Adobe for creating and editing image files. It is also the program used at Gustavus for importing images from scanner workstations, which can be found in numerous labs throughout campus.

Resizing images

<video width="320" height="240" class="boxright">Resizing_images_in_Photoshop.flv</video> To resize an image:

  1. Go to the Image menu and choose Image size...
  2. A box will appear in which you may choose new dimensions of the image.

The image will automatically scale, meaning that if you enter a new width the height will automatically change according to scale.

Note: The Adobe CS5 looks a little bit different than the version depicted in the video to the right, however the procedure works exactly the same.

Scanning Documents

Use Photoshop to scan pictures, documents, or slides. Note that slides usually require an additional adapter for the scanner, ask the lab attendant where the scanner is located if you would like to you a slide a adapter.

At this time scans can only be directly imported into Photoshop on Windows machines. If you are looking to edit a scan in Photoshop using Mac OSX, press the scan button on the machine and scan the image using the Image Capture software that will automatically pop up. The image of the scan will then be saved in your documents. Then load Photoshop and go to open --> documents and select the image you just scanned.

To scan a document to Photoshop using Windows:

1. Choose File > Import > WIA Support. 2. Choose a destination on your computer for saving your image files. (Generally choose "Documents" unless saving to a flash drive or other device) 3. Click Start. 4. Make sure that Open Acquired Images in Photoshop is selected. If you have a large number of images to import, or if you want to edit the images at a later time, deselect it. 5. Make sure that Unique Subfolder is selected if you want to save the imported images directly into a folder whose name is the current date. 6. Select the scanner that you want to use. The scanners in most labs are Epson 4870 or V500. 7. Choose the kind of image you want to scan:

    Color Picture
         Uses the default settings for scanning color images.
    Grayscale Picture
         Uses the default settings for scanning grayscale images.
    Black And White Picture or Text
         Uses the default settings.
    Adjust The Quality Of The Scanned Picture
         Uses custom settings.

After the settings are all correct, hit scan and an image of the item you are scanning should appear in a window in Adobe Photoshop, from here make any cropping or image size changes you would like to make and then go ahead and save the picture. Photoshop usually defaults saved documents to the .psd format, make sure you change this if you are intending on using the image outside of photoshop, common formats for images include .jpg, .bmp (both lower quality), and .tiff or .png (usually higher quality, but larger files).

Use the Filter Gallery

To quickly add a creative twist to any image you can use the Filter Gallery, introduced in Photoshop CS3, and used ever since. Before editing an image always remember to create a backup copy before you start so as to not lose any data. To use the filter gallery open the image you wish to edit in Photoshop and then go Filter-->Filter Gallery. Here you are presented with a wide array of filters to apply to your image. Choose which filter you wish to use, tweak the levels on the right side of the window until you are satisfied with the image, then click okay. Again, make sure you pay close attention to the format of the image when you save, .psd is only necessary when you wish to edit the photo in Photoshop again.
