Assignment 2
Color Composting

CG foreground, live background

Process

  1. Took the image of the mannequin bent over like he was reaching for the bench
  2. Rendered the bench out in Maya using three lights. Main light on right of image, fill light on left and back light to match the photograph
  3. Using the Alpha channel created in Maya as the base mask I painted in the area where the hand goes over the bench
  4. Shadows were rendered out in Maya
  5. I used in inverted version of the bench mask for the base shadow mask and painted out the other areas I didn't want
  6. The shadows were applied with a multiply filter

Live Foreground, Live Background

Process

  1. Took image of the door
  2. Took the image of the mannequin against a green backdrop outside in front of the door so the lighting was the same
  3. Keyed off the green to get the initial mask for the mannequin
  4. Cleaned up the mask in photoshop using a paintbrush
  5. Corrected the color of the mannequin using curves
  6. Created the shadows by painting them in and applying a multiply filter
  7. Blurred the shadows to soften the edges
  8. After Critique: extended shadows to match more like the buckets shadow

Live Foreground, CG Background

Process

  1. I had the image of Nellie from my old job.
  2. I created the mask in Photoshop using a variety of tools. The basic mask was created by applying curves to one of the color channels. It was then cleaned up using the pen and paintbrush tools.
  3. The office space was created in Maya and rendered out using Mental Ray and GI (This took the most time trying to get the parameters just right for the ray tracing)
  4. The Shadow was created off of Nellie's mask. From there I hand painted in the shadows for the desk and then applied with a multiply filter
  5. After Critique: I took the image of Nellie and flipped it upside down and turned down the opacity in order to simulate the reflections on the floor.
