An Introduction to Photoshop
Clive R. Haynes FRPS
The initial purpose of this section is to provide information for a series
of introductory talks at a local photographic society
I hope the information will be of benefit to others as well
Photoshop is a vast and fascinating program, specifically aimed at photographers and graphic designers. I'm a photographer so my approach is necessarily from that discipline.
In this introduction to the program I'm concentrating upon the basic functions and tools that I feel are most appropriate for a photographer. There's a great deal of overlap between photographers tools and the tools that someone working in the graphic arts would use. With such a large area of common ground we all have our favourites and preferred methods.
|The introduction will be a series of 'links' to appropriate pages on my website. Please note that as Photoshop has evolved over many versions and I've been using it since version 4 (around 1997) some pages may reflect the way in which the general layout appeared in an earlier form. I've tried to update where possible, however I must make allowances for people using older versions. Sometimes I present an option for one version or another however at other times, if I consider the change to be mostly 'cosmetic', I'll leave the earlier one in place. With a little interpretation and common sense most things can be translated from one version to another.|
The basic topics I'll be covering will be:
Cameras - How many Mega-Pixels?
types - JPEG, Camera RAW, TIFF, PSD, DNG etc
use 'RAW' Files?
An introduction to working with 'Selections': Defining specific areas in which to work and apply changes
How Big Should My File Size Be? Resolution & Definition - Explanations & Considerations (ppi & dpi) How Many Mega-Pixels Do I Need? 8 bit or 16 bit - Why the Choice?
Making more complex 'Selections' Refining and modifying the selected area and using 'Quick Mask'
What are Layers? A basic introduction to this essential component of Photoshop
