New on-line services raise the bar on digital output.

Back in 1999, I remember paying $15 per print at a local service bureau to get high-quality prints of my 3D renderings. Cheaper ink-jet and dye sublimation prints were available, but those were subject to fading in bright sun, and didn't have the crispness and color fidelity of a color photograph. Hoping to capitalize on the consumer digital camera craze, new web-based businesses are cropping up that make real photographic prints (developed on real photo paper with a silver halide chemical process) from any digital file you upload or e-mail. The prices generally start at below 50 cents a print, with some services now offering the first prints for free in order to lock in new customers. The first service I tried was PrintRoom.com. I uploaded a 3D rendering that I had sized to 8x10 at 300DPI, as well as several pictures I had taken with my Nikon Coolpix 950 Digital Camera. All arrived in the mail within four days, printed on Kodak paper. The picture quality was excellent, even the 8x10 prints from my Nikon 950 pictures were crisp, colorful, and showed no signs of blurring or pixelation. I've also heard very favorable feedback about the picture quality from Ofoto.com. Many of these services are using similar film recording and processing equipment. Images are printed by these services directly in RGB, with no need for color separation to CMYK colors (as are used by some kinds of color printing.) Color accuracy from PC screen grabs and digital camera pictures is preserved with this system. You do not need to set a DPI for the files as you would for a printer. Images are sized to the size of photo print that you choose, such as 8x10. The web sites have their own recommendations for pixel-resolutions that work best at different print sizes, generally 1024x768 or lower should be limited to 4x6 prints, 1280x1024 can be a 5x7, or 1600x1200 makes a good 8x10. Higher resolutions make better prints, even at smaller sizes. If you are looking for a quick & free way to show-off your artwork on the web, many of these services also let you maintain an on-line "photo album" of images you upload. If you have any kind of digital images to display, services like PhotoPoint.com can be one of the fastest ways to create a portfolio website, whether or not you order any prints from them.
