Choosing a Computer System for Digital Imaging
by Darron Spohn, January 2002
This article discusses what you need to consider when choosing a computer system
for digital imaging work. Digital imaging, in this context, is defined as getting a
still photograph into a computer and preparing that photograph for printing. If you
are shooting with digital cameras you can skip the section on scanners. This article
will discuss general principles in choosing a system, but will not delve into specific
hardware recommendations.
Computer hardware is evolving rapidly. What is state of the art today will be off
the market in nine months.
Choosing a Monitor
This discussion starts with monitors for the simple reason that the monitor is
critical to a digital imaging system. Just as light is the most important element in a
photograph, the monitor is the most important component in the digital imaging
workstation.
Get a monitor that gives you control over the individual electron guns. This may
take a bit of research on your part, but it is essential to matching screen display
with printed output. Another consideration is aperture grill versus shadow mask.
Aperture grill monitors are sharper than shadow mask monitors. This is not
important in most tasks, but when you're looking at a 24x30 inch image at actual
size to clone out dust and scratches it is vital that you have the sharpest monitor
possible. Research the various manufacturers' web sites for specifications. Look at
the aperture grill models only, and make sure you see something that states the
monitor gives you individual controls over the R,G, and B intensity, and the white
point settings.
You also want a monitor with a flat screen. These cost a bit more, but are well
worth the extra expense. The flatter screen means you won't stare at distorted
corners when you're working on your images. Spend the extra money and get the
flat-screen.
