Digital Imaging

The Digital Darkroom

Once an image is captured on your camera, it will end up in your imaging workstation where the fun begins.

If you are not computer-savvy or if you don't know Photoshop, then digital will be much less useful to you. Learning color management and workflow issues will overwhelm some people. Not everyone can learn to take advantage of the digital explosion. But there are new tools introduced every month that make the process easier. Within the decade, this problem will be solved.

 Online working storage for jobs in progress is handled by the workstation's RAM, which is why machines are usually loaded with 128MB, if not more RAM. The hard drive also serves as a "scratch disk" when larger images exceed the capacity of a system's RAM.
 Transportable storage is covered by systems such as Zip and Jaz drives from Iomega, as well as SyQuests and magneto-opticals. Recordable CD's are also popular with photographers who can give their clients non-erasable images on the CD.
 As your digital image repositories grow, so do the need for long-term image storage and retrieval.

Essentials of Digital Photography
 Essentials of Digital Photography is for Adobe Photoshop users who are serious about getting into the nitty-gritty of digital photography and producing professional-quality work. This full-color guide takes an in-depth look into using digital cameras, scanning, calibrating your monitor, color-correcting your images, and creating photo montages, all the while explaining technology and technique thoroughly.

Color Proofers

 For most photographers, after images are captured, enhanced, and color convereted, they need to be output as color proofs. The most popular devices are the wide variety of desktop dye-sublimation printers normally costing from $8,000 to $18,000. For those with larger budgets, digital color proofers costing as much as $40,000 may be the answer. Dye-sublimation printers require less maintenance than proofers such as the Iris which requires maintenance contracts costing hundreds of dollars each month.
 For those with very tight budgets, Epson's Stylus Color 3000 inkjet printer might fill the bill.

Price Max. Size Max. Resolution (dpi)

High-Res Inkjets
Agfa Atlas $32,000 34.5x47.5 300



Scanners



Color Management

 If you want to be able to produce predictable color in-house, as well as calibrating with outside vendors you will need to have a workable color management system in place. The purpose of color management software is to keep the colors that you specify in a file as consistent as possible throughout your work flow, as files move through the various peripherals (scanners, monitors, printers) to final output. Each device has its own way of representing color and with each step, there is the potential for problems.
 There are a number of color management software packages on the market today. What's important is the product must work with image data to create ICC-compatible, device-independent profiles. It is beyond the scope of this page to fully explain color management theory, but suffice it to say that relying on Photoshop alone will not give you color-calibrated, press-ready files. Without an effective color management system, your file's color will not remain true, as each application writes to its own color management scheme with little interaction with the operating system.
