Lecture 104 Practice:


After the last lecture, you journeyed out to take photographs. Today, we will begin to develop a workflow for post processing captured images in Adobe Photoshop. There are several tutorials in The Digital Tools For Architects Handbook that will help you through each part of today’s exercise.

Part 1:

  • Choose 3 images (your favorites) from any of your previous photographs.  Please perform the rest of the steps in part 1 to each image.
  • Following the “Photoshop 1.1 [black & white]: Turning a color image to black and white,” you will create a new adjustment layer and work with the channel mixer to turn your image to black and white. Remember, you can turn off adjustments by clicking on the eye next to the layer name. You may wish to do this before the creating the next adjustment layer.
  • Follow the “Photoshop 1.2 [levels]” tutorial and create another new adjustment layer with a levels adjustment.
  • Follow the “Photoshop 1.3 [curves]” tutorial. You will again create a new adjustment layer.
  • Follow the “Photoshop 1.4 [pop]” tutorial. Again you will get a new adjustment layer.
  • Follow the “Photoshop 1.5 [dodge & burn]” Tutorial.
  • Save your work as a .psd if you have not already done so.
  • Now, turn off all adjustment layers so that you see your original image. Following Photoshop 1.6 [save for web], save a web version of your original photo.
    • Note: If you are using Adobe Photoshop CC, the "save for web" option is no longer available.  Instead do a Save As... and choose .jpg as the type.
  • Repeat once for each adjustment layer. Make sure you give each photo an explanatory name (A135A_20160203_photo_original_web.jpg, A135A_20160203_photo_bw_web.jpg, A135A_20160203_photo_levels_web.jpg, etc.) You can choose to stack the adjustments or to save them individually at your discretion.

Part 2:

  • You should have 18 images when you are complete including the original images. Following the steps outlined on the back of this page, upload the images you created today.
  • Remember to add “Exercise 104”, “Digital Tools for Designers” and “Exercises” to the categories field.
