Introduction:

In this exercise, you will work on each channel of the image you rendered in Previous Exercises.  You will also combine other imagery from the web or our course website to create a representation of your design.  The strategies employed in this exercise will vary based on individual imagery and I will demonstrate many different strategies for post-processing.

  • Note:  While the exercise above is optional/suggested for today, you may instead choose to work on your final renderings for Assignment 205.  You should, however, post a rendered image of your work from today and tag that work with Exercise 229 to get credit for today’s exercise.

Part 1: Z-Depth

  • Follow V-Ray 8.31 [Z-Depth] to set up a proper Z-Depth channel before rendering.  You may wish to do a small rendering to test to make sure the Z-Depth looks appropriate [This will be demonstrated in Lecture 229]
  • Render your final image in high quality.
  • Save your image and all channels to your flash drive.
  • Follow Photoshop 1.25 [Z-Depth] to adjust the focal length of your final image.

Part 2:  Adding the Background and Collage Elements.  (The steps below can be done in any order)

  • Find images of people/animals/etc. to inhabit the space.  You can search the course website repository (Collage Elements section under the Resources tab) for images or you can find your own.
  • Place these images in your rendering and scale them appropriately.  Remember to adjust for your horizon line and make the people properly sized for the perspective.
  • Find an image that approximates the landscape in your rendering (This could be a grassy field, rocky cliff, etc.)  Place this image in your drawing where the landscape should be.
  • Use the Polygonal marquee (or create a curve in the curve window and draw with the pen tool) and delete parts of the image that don’t fit with your image.
  • Use the clone stamp tool with an appropriate brush (if grass, use the grass brush) to make your texture overlap your building.  This will add realism to your rendering.
  • Add additional trees, shrubs, brushes, etc. where appropriate.

Part 3: Finesse & Final Image

  • I will demonstrate a number of optional techniques in the lecture.  You can perform these by following tutorials mentioned.
  • Use File>Save As to save your final work.  Post this work to the course website.  You should comment on 3 other students’ work.
    • Note:  While the exercise above is optional/suggested for today, you may instead choose to work on your final renderings for Assignment 205.  You should, however, post a rendered image of your work from today and tag that work with Exercise 229 to get credit for today’s exercise.
