Thumbnails
Thumbnails are images of reduced resolution and used for a faster display of the raw images. They are created by Create thumbnails command from the Utility pulldown menu in the TPhoto window. Thumbnails for multiple resolution ratios can be created in one processing step.
Thumbnails are used by:
•Define color corrections display
•Active full view in tie point mode
•Define color points display
•Display mode visualization
It is strongly recommended to create thumbnails at the beginning of the processing workflow, because they speed up the image display for these processes essentially.
