Introduction
Computers have become critical components in the photographic workflow process. These machines handle everything from processing and transmission to storage and organization. As such, ProPhoto Wiki has a wide range of articles to assist photographers in their use of this critical piece of equipment in their workflow.
Selecting Components
Selecting a computer for image processing tasks can often be a daunting task as there are many different factors that need consideration. Any computer will only be as fast as its slowest component, so it's important to select a machine that is well balanced for the workflow for which it will be used. The following sections provide links to articles outlining the details of these various components to assist users in their selection.
Motherboards
An often overlooked component of a computer, the motherboard is the glue that holds all of the other parts together. There are several important components placed on the motherboard itself, which are covered in the following sections. See this article for more information.
Microprocessors
The CPU is generally the part of the computer that most people will focus on first. It is the component that drives everything else in the computer and what will handle the number crunching necessary to process the images passing through it. For more information, please see this article.
Memory
One of the most significant factors in the performance of an image processing system, the main memory is a critical component. All working data is stored in this bank so that it can be fed to the processor for computational tasks. Please see this article for further information.
Hard Drives
Another critical component in an image processing machine, the hard drives are the repositories that permanently store all programs and data that will be used by the machine. In addition, hard drives are also used as temporary working areas for tasks that require more space than is available in main memory. See this article for more information.
Video Cards
The interface between your computer and monitor, the graphics card is an important component in any computer system. While it may not have a lot of effect on performance, the quality and connectivity options that it provides will be important factors to consider. Please read this article for more information.
Monitors
As the device ultimately responsible for allowing users to examine the images stored on the computer, the monitor is a critical piece of equipment for any imaging computer. A variety of different technologies and features are available on the market at this stage so there are many things for users to consider. Please read this article for more information.
Input Devices
The instruments used to control the various tools on the computer, input devices like mice and graphics tablets can be extremely important. While often not a major consideration for many photographers, if detailed touchups are required then it is generally a good idea for users to consider more sophisticated tools. Please read this article for more information.
Power and Cooling
One of the most underappreciated components of any computer, the power supply and cooling systems are some of the most important factors in the overall stability of the system. They are connected to every component in the computer, so any problems in them can carry through to everything else. Modern computers consume much more power and produce much more heat than previous generations so the importance of these systems has grown significantly. Please read this article for more information.
Imaging Performance
With all of that said, the important point for photographers is how all of these variables affect everyday workflow. This article provides a basic synopsis of how these various characteristics interact with one another and your workflow. For more detail on individual components, please visit the articles linked in the above descriptions.
Portable Computers
Laptop Computers
Providing very similar functionality and performance to mainstream desktops, these computers allow photographers to perform their work efficiently in the field. To suit different needs, these come in a wide range of different sizes - from large 17" desktop replacements to small and thin 12" ultra-portables.
Tablet PCs
Very similar in functionality and design to the above, tablets provide a screen that can be controlled by a stylus. That allows these machines to be realistically used while standing up, so they can be useful to some photographic disciplines.
Ultra-Mobile PCs
A new form factor falling between laptops and handhelds, these are fully-functional computers with a much smaller footprint. While not the fastest, these devices run standard OSes so they can use any software that will run on larger computers.
Handheld Computers
Generally running special-purpose OSes such as Windows Mobile or PalmOS, these computers have more limited functionality than the above categories. The advantage, however, is that these devices will generally fit into a pocket, provide much longer battery lives and can instantly switch back on.
