GDES 230 - Advanced Image Editing and Correction

(R only) (Also offered as PHOT 230 . Credit cannot be received for both GDES 230 and PHOT 230 .)

An advanced study of digital editing and image correction as it applies to the needs of the graphics or photography student and professional. Students perform contrast and color correction on more difficult scanned images and digital photographs in an effort to gain aesthetic control of the image prior to final output. Topics also include visual and mechanical calibration of input and output devices. PREREQUISITE(S): GDES 214 , PHOT 214 or consent of department. Two hours lecture, four hours laboratory each week. Formerly GD 230.

4 semester hours
