Digital Imaging Fundamentals

Attended another course at Philippine Center for Creative Imaging (PCCI). The "darkroom" of digital photography is Adobe Photoshop (or other digital imaging software). Thus, decided first to take the pre-requisite course, Digital Imaging Fundamentals and Color Management, before I take the Adobe Photoshop CS2 Basics.

These are the things I learned today:

• The process of digital imaging: (a) converting analog images into digital data, (b) manipulating digital images, (c) outputting digital images.


• To avoid degradation of an image in Adobe Photoshop: (a) use of free transform, (b) use as smart object, (c) use layers, etc.


• You must avoid resizing of images. From low to high resolution, softens the image.


• If you need to make an image bigger, use "bicubic smoother".


• If you need to make an image smaller, use "bicubic sharper".


• If you need to make a square bigger, use "nearest neighbor".


• Calibrating the monitor: (a) Should calibrate at the light you would be working on. (b) Use gray background/desktop. (c) At Control Panel, double click "Adobe Gamma". (d) Choose the wizard. When adjusting the gamma, uncheck the single gamma to adjust the three colors; squint eyes while adjust. Suggested gamma for Windows is 2.20 and 1.80 for MAC. For the hardware white port (temperature of light used by the monitor), there would be 3 gray boxes. Click the two (2) outer boxes to the middle box the gray you like. Choose 6500 kelvin (daylight). And lastly, save profile.


• Before working with Adobe Photoshop: (a) Calibrate monitor. (b) Set settings of color: For photographers and graphic artist, use Adobe RGB. For web designers, use sRGB.


• When printing using your printer ("document") and you let Adobe Photoshop dictate the color, turn-off Color Management System (CMS) of the printer.


• When printing to simulate printing process, choose "proof", let Adobe Photoshop dictate the color, turn-off CMS of printer.


• When scanning, assign scanner profile then convert profile to Adobe RGB.
