**Adobe Photoshop**

**Resizing Images to a 4:3 or 3:4 aspect ratio:**

-   Under the "Window" menu at the top of your screen, make sure you
    have the "Tools" and "Options" window checked and open. You may also
    want to make sure the "History" window is checked and open (this is
    you master undo/redo list).

-   Select the "Marquee" tool in the top, left of the Tools window.

-   Left click and make sure you have the "Rectangular Markee Tool"
    selected.

-   In the "Options" menu on the top of your screen, click the Style
    menu arrow and scroll down to "Fixed Aspect Ratio."

-   If you are working with a layout view image, set the width = 4, and
    Height = 3. If you are working with a portrait style image, set the
    width = 3, and Height = 4.

-   Select a section of your image using the marquee tool.

-   Go to the "Image" menu at the top of the screen, and select "Crop."

**Resizing images to 72 pixels/inch, 600 pixels wide:**

-   With your image active, go to the "File" menu and select "Save for
    Web." You image will open in a viewer.

-   In the lower right side of the menu, you will see two tabs that read
    "Color Table" and "Image Size." Select the "Image Size" tab.

-   Under the "New Size" section, click in the window next to "Width"
    and type "600." The height will automatically adjust.

-   Click the **"Apply"** button at the bottom of the "Image Size"
    screen. You should see the image preview to the left change.

-   The area underneath the preview window to the left provides you with
    the modified image information, including the file type and size.
    You can see the results of your modifications before they are
    permanent here, and adjust the quality of the image accordingly to
    meet a certain image size, eg. An image less than 1MB in size.

-   To adjust the File Type: The top right section of the "Save for Web"
    screen is called "Settings" and will enable you to change almost any
    image format to a .JPEG or .GIF image. Select "JPEG" in the scroll
    bar underneath the "Settings" title.

-   You can adjust the Quality, and therefore the final image file size,
    but changing the quality of the image. Underneath the "JPEG"
    selection you can simply choose Low, Medium, High or Maximum as a
    setting. Medium and higher are appropriate for the web.

-   You can also adjust the quality as a percentage by adjusting the
    number in the "Quality" field. FYI, the preset quality settings to
    the left of this field are representative of percentages: Low=10,
    Medium=30, High=60, Maximum=80.

-   Make sure the "Optimized" box is selected- it will ensure the final
    file size is at the maximum efficient compression.

-   When you are done making your image adjustments, click on the "Save"
    button at the top right of the "Save for Web" screen.

-   Give the image a [New]{.underline} filename and choose your save to
    location. The original image will not be written over unless you
    choose to replace the image here. If you accidentally hit "Save" to
    save over the original file, you will receive a dialogue box asking
    if you intend to replace the original image.

**Basic Image Adjustments**

-   [Rotate your image:]{.underline} Navigate to the "Image" menu.
    Scroll down to "rotate canvas" and select your desired rotation.
    Using the "Flip" options located here, you will flip the image and
    provide a mirror view at the same time.

-   Most of the adjustments you will want to make can be found by
    navigating to the "Image" menu, and scrolling down to "Adjustments."

    -   "Auto-Color" and "Auto-Contrast" are two good choices.

    -   "Variations" is very useful. If will show you possible
        variations of your image if you were to make it a little bit
        brighter or darker (left side), or add more of a particular
        color (bottom center). Your original image will be compared with
        a "preview" of the final state of the same image with
        modifications you choose here. Choose to make an image a little
        bit brighter, add some red, and then a bit of green. Compare the
        changes in your preview window above. Play around with this
        feature a little bit and you will see how useful it can be.

-   When you are done making changes to your image, you can save over
    the image in progress by selecting "File  Save," or keep the
    original image and save the new version by selecting "File" and
    choosing "Save as..." to save the image with a new name.
