Once you've completed the planning process for objects, you're ready for the next phase - capturing the source images you'll use to create the QTVR object movie. This stage should encompass preparing the object and equipment as well as capturing the source images themselves.
Preparation and Setup for Object Image Capture
Preparing to capture the source images for objects involves three main tasks:
- preparing documentation
- preparing the object
- preparing the image capture equipment
DOCUMENTATION - The documentation tasks for QTVR objects should include:
- identifying the types of backgrounds and files required for any video compositing
- preparing a documentation notebook to record special conditions or situations during the shoot
OBJECT PREPARATION - Object preparation tasks vary depending on whether you are shooting an object in a studio or in a less controllable setting, such as an outdoor sculpture garden. Preparing the object will frequently be the most time-consuming task of creating QTVR object movies.
When capturing images for large objects outdoors you will mark the position of the camera for each of the shots and where possible adjust the overall lighting for the views. Shooting objects outdoors is perhaps the most challenging type of QTVR object assignment, as creating consistent lighting for all shots can be very difficult. In addition, accurate registration of the camera setup points and consistent distances between each shot will directly reflect how smoothly the final QTVR object movie rotates .
For indoor or studio capture situation, your tasks will involve preparing the object, dampening any highly reflective surfaces, and stabilizing the object on some sort of elevated platform so the object can be rotated between each image.
EQUIPMENT PREPARATION - Preparing the image capture equipment is relatively straightforward for objects. The camera should be setup on a sturdy tripod. If capturing images using still photography, you should have enough film loaded to last for the entire shoot so you won't disturb the camera. If using video, be sure you have adequate video tape or, if digitizing directly as you capture, verify that you have adequate hard disk space to hold the resulting images. This is especially important when capturing images at larger frame sizes, or when capturing extensive shots for looping object movies.
