Assignment #23

Photoshop Project 8
Due Date: February 25

Instructions

Move a photographic element from one photograph to another. Use an alpha channel to create a mask and a selection. Review Lesson 07e/f for help in making masks and alpha channels.

  1. GET SET UP
    1. Create a new folder in your username folder called "Lastname Project 8". (Be sure to replace "Lastname" with your actual last name.)
    2. Get two photos. One will be your desired background (we'll call this image 2). The other will have your desired foreground image against an unwanted background (call this image 1.)
    3. I will be grading on difficulty. A foreground image which is super easy to mask from its background will not score as highly as a challenging one.
    4. Open the photographs in Photoshop.
  2. CREATE THE MASK & ALPHA CHANNEL
    Using the skills you learned in Lesson 07, combine the foreground element from image one with the background in image 2.
    • You can use any selection tool, then go into Quick Mask mode to edit the selection.
    • Save the selection as an Alpha channel.
    • Another method is to use Calculations to help create a mask.
    • Edit the Alpha Channel to perfect the edges of the mask. Remember: paint with black to mask pixels out, and paint white to include pixels.
  3. SAVE AND MOVE
    • When your Alpha channel is perfect, save image 1 as "image1.psd". Make sure the Format in the Save as... dialog box says "Photoshop".
    • Load your Alpha channel as a selection and move the selection onto image 2.
    • Place the new foreground where you want it in image 2.
    • Save the combined image file as "final.psd". Make sure the Format in the Save as... dialog box says "Photoshop".
  4. TURN IT IN
    Turn in the entire "Lastname Project 8" folder into the "Project 8" folder in the Inbox. I should see the following in your "Lastname Project 8" folder:
    1. image 1 with the desired foreground and unwanted background
    2. image 2 with the desired background
    3. "image1.psd" with your masking Alpha Channel saved in the Channels palette
    4. "final.psd" which combines the two
