Homework #13
Creating stereoscopic 3D images.
For this assignment you will create at least three different stereoscopic images from photographs.
At least one of the images should have you appearing in the photo and at least one of the images should be a recognizable location on campus.
You will be graded on the composition so plan your scenes to make them interesting (especially for 3D).

Stereo 3D Photos with Photoshop
Steps for creating stereo 3D photos in Photoshop:
1)Snap a photo, move 3 inches to the right, take a second photo. Avoid having objects closer than a yard away from the camera and no moving objects!2)Open both images in Photoshop. Hold the shift key and drag the right eye image on to left eye image.3)Rename the layers “Right Eye” and “Left Eye”; make sure the Right Eye layer is on top.4)Double click the Right Eye thumbnail to open the Blending Window. In Advanced Blending uncheck the Red Channel for Red/Cyan glasses (or Green Channel for Green/Magenta glasses).

Homework #13
Course website has details and tips on making 3D photos.
Upload your photos to your blog in an entry entitled “Creating Stereoscopic 3D Images”
Extra Credit: You can also create a pair of stereo-ready images in Autodesk Maya by rendering a scene for one image, then shifting the camera position and rendering the second image.
Extra Credit: Create a 3D animated short, either by stop motion or in Maya. Ten bonus points for a good animation; twenty bonus points for a great one.

Review Question
The ear hears sound waves and senses the wavelength of the sound as the pitch.
The eye sees light waves and senses the wavelength of the light as color.
The ear doesn’t have a “lens” so it can’t form an image but otherwise the ear and the eye are very similar. True or False

The Ear vs. The Eye
AE D
How the ear senses sound waves is distinct from how the eye senses light waves.
Hearing an E and a D together does not sound like an A.
Seeing green and red together does look like yellow light.

Thermal Light Sources
When objects glow with heat they emit light in a broad spectrum, called the blackbody spectrum.
The peak of that spectrum shifts from red to blue as the temperature increases.
![Page 21: Upcoming Deadlines Homework #13 – Creating Stereoscopic 3D Images Due Tuesday, May 15 th (Last day of classes) 20 points (10 points if late) Final Exam](https://reader035.vdocuments.site/reader035/viewer/2022062409/56649f455503460f94c67174/html5/thumbnails/21.jpg)
Thermal Light Sources
Notice that the color of thermal light sources goes from red (2000K) to blue (12000K) but it is never green.
Spectrum is broad around 6000K so we see it as white.

Paints are suspensions of pigment particles.
Different types of paint (watercolor, acrylic, oil, gouache, etc.) are just different binding solutions for holding pigment.

Demo: AlexandriteThe color change from red to green is due to strong absorption of light in a narrow yellow portion of the spectrum, while allowing large bands of blue-greener and red wavelengths to be transmitted. Typically, alexandrite has an emerald-green color in daylight (relatively blue illumination of high color temperature) but exhibits a raspberry-red color in incandescent light (relatively yellow illumination).

Black Paint
Black paint reflects more light (has higher value) than you may think.
Compare the value of the matte black paint with that of the holes.

True Black

Surprisingly, even the lunch box painted white inside doesn’t reflect much light out the hole.
White in the shadow is darker than black in the light.
