Introduction:

In this exercise, you will work 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 chanel 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 chanels 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 4: Finesse & Final Image

  • I will demonstrate a number of optional techniques in 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.
