Building a scanner profile is easy as cake: You scan or print the correct Profile Target and then measure it. If you own LaserSoft Imaging SilverFast Studio scanning software, you will have received a target to scan in the box. With SilverFast, creating a scanning target is absolutely painless. Building a custom profile for an output device is also relatively straightforward if the printer is well-behaved, that is. If it is not, there's trouble in Paradise.
To create a scanner profile from scratch, you first need to read on at it-enquirer.com/...

Print with Colour Management
"You don't need to be an expert in colour management to print from Photoshop, but it helps".
The engineers and interface gurus at Adobe must have been reading the same article because the print workflow within Photoshop CS2 has undergone a very significant overhaul. In this tutorial Ian Lynos at computer-darkroom.com will discuss these changes in detail, so that by the time you finish reading it you too will be an expert in Photoshop print colour management (dream on!).

Making ICC profiles for devices
An ICC device profile contains the information needed to transform colour data between device values and a device-independent CIE-based colour space. The ICC specification contains full details of the structure of such profiles.
To make an ICC profile for a colour device you need a profiling package. This normally includes a measurement instrument, a test target, and a software program which can read the measurements and generate the profile.
For an output device (display or printer) colour patches are displayed or printed and then measured. For an input device (scanner or camera) the test target supplied with the profiling package is captured and measurements of the target will usually be available within the software.
Once the software has the device data and the corresponding measurements, it proceeds to create the data structures which form the profile. Depending on how complex the device is to model, the profile may be anything from 1K to several MB in size.
You can see the data in the profile by opening it in a profile inspection utility such as Profile Inspector.
The International Color Consortium has more about it.

7 ways to preserve printer ink
We all know replacement inkjet cartridges can be quite expensive, so the following are a few random tips to prevent your ink- and wallet - from running dry...
by Marc Saltzman
* If you're looking to print a couple of dozen photos, don't do it yourself as it's more economical to drop off your memory card at a photo mat (like we used to do with film!), use a photo kiosk at the mall or email your photos to one of those services that prints them and sends them to your door.
* Stick with brand name ink. While it will cost more than the no-name ink, it will last longer and your photos will last longer too. To give your prints the professional look, and to make sure they last a long time, be sure to also buy premium photo paper, be it glossy or matte. Cheap ink also has been known to dry directly on the printer heads which can cause performance problems.
* Replacement cartridges for ink are a good idea to keep on hand but make sure they're in a sealed container or 'zip-lock' bag so no air can prematurely dry it up.
* Try to practice 'selective printing' - decide what you really want in paper form and what you can live with just on your computer. If you look through your photo album, you'll probably realize you didn't need to print off every one.
* When your printer tells you it's time to replace the cartridge - ignore the warning for a while. You probably sill have enough ink to last for a few more days...or even weeks. When you begin to see the black text fading or the colour just isn't right in a photo, then you can change it.
* Finally, before you print a photo, document or page from a Web site, select 'Print Preview' from the File tab to see what it will look like when printed so that you can catch mistakes before wasting ink.

Make Your Photo Prints Last
Just like memories, old movies, and eyesight, pictures inevitably fade. It doesn't matter what kind of photograph you have; the ink eventually fades and you end up with a picture that looks like it came from an antique store. Prints made from 35mm film tend to fade noticeably in less than a century, while most ink jet prints fade in a fraction of that time.
So what can you do about it? First, acknowledge that your digital photos won't last forever. Second, remember that you can keep the original digital file around and reprint it whenever your print is no longer fun to look at.
This week, I've provided a few tips for getting the most longevity out of your ink jet photos.
The Roots of Fading
So why do prints fade? If we know the cause, we may be able to stave off the inevitable a bit longer. It turns out that ink jet printer inks are sensitive to ultraviolet light. As a consequence, your images will fade faster if exposed to direct sunlight for extended periods.
That's not all. Some inks are also sensitive to airborne chemicals and contaminants--especially ozone. The solution to that problem is simple: Protect your prints from direct exposure to the air. Ideally, that means storing them in deep space. If that's not possible, keeping your prints under glass or plastic can preserve them for a very long time.
How Long?
When properly protected--that's a caveat all ink jet paper manufacturers use when describing their paper--you should expect most modern printers to create images that last from 5 to 50 years before fading. For example, Epson's standard Photo Paper has a rated life of 6 years before fading, while its ColorLife Photo Paper is rated for 27 years.
In addition, some ink jet printers are designed to produce images with extremely long resistance to fading. Most garden-variety ink jet printers use dye-based ink. Intended for serious photo enthusiasts, pigment-based ink jet printers (like the Epson Stylus Photo 2200) can deliver a print life of well over 100 years, according to their vendors. Pigment-based inks aren't as vibrant as dye inks, though, so some folks prefer the shorter-lasting prints.
Taking Precautions
Armed with that knowledge, you can take a few easy steps to give your prints the longest possible life span.
Start with the printer, paper, and inks. I've said it before, and I still believe it's true: Use inks made for your printer, not inexpensive replacements. Also, do some comparison shopping and buy paper that's designed to be "archive quality" or to deliver the longest lightfastness. Typically, you'll find that this stuff costs about a dollar per page--certainly not cheap, but it's affordable if you use it only to make the final print.
Once you print a photo, allow it to dry completely before placing anything on it. Although an ink jet print may feel dry to the touch in minutes, it actually takes about 12 hours to dry. Once the print is dry, protect it by sliding it into a plastic sleeve or covering it with glass. If you're filing the image in a photo album, you're done. As long as you store the album in a reasonably dry environment, your pictures will last a very long time, since the photos will have virtually no exposure to air or light.
If you plan to frame your picture and hang it on the wall, though, be careful about where you put it. Keep it out of direct sunlight, for instance, even when it's behind glass. Try to hang the print where the sun won't shine directly on it. And if the print will be routinely exposed to direct sunlight, consider using UV-shielded glass, which is available at most framing shops.
Finally--and this may seem obvious, but newcomers to digital photography don't always think of it--let me suggest that once you've printed an image, don't throw away the original digital file. If you keep the file, you can reprint faded or damaged images whenever you need to. CD-Rs make an inexpensive and reliable way to archive your photo files, if you store them carefully in a dark location where they won't get scratched. (Here's another situation where you don't want to pinch pennies: Buy high-quality discs from a recognized manufacturer.)
PCWorld.com did an investigative report on the topic of print fading about a year ago. Much of the information in "Fight Photo Fade-Out" is still useful; check it out for more details.

How To Preserve Photos For 500 Years
Arik Hesseldahl wrote on Forbes:
"Consumers have some latent fear and doubt that they don't have time to manage the storage of their photos, or they're unsure about how to do it."
In May 2004, the firm found that 59% of digital camera users make backup copies of their digital photos, but less than half have backups for their backups. Some use online photo sites like Shutterfly, Hewlett-Packard's (nyse: HPQ - news - people ) Snapfish or Eastman Kodak's (nyse: EK - news - people ) EasyShare Gallery service.
Managing these files is a trickier issue for professionals, partly because of the volume of files to save and store, not to mention the potential for a loss of livelihood.
"Everyone sees the mass of digital files that everyone is holding as a growing problem," says Jack Reznicki, a commercial photographer in New York whose clients include AT&T (nyse: T - news - people ) and Toys "R" Us (nyse: TOY - news - people ).
For other photographers, archiving is critical because of the historical importance of the subjects being photographed.

Film Speed Rating - ISO / ASA
All film has a speed rating, whether digital or traditional. You may see this number called ASA or ISO (both indicate the film's rated speed). The ISO / ASA rating describes how quickly the film reacts to light.
Film speed uses stops, just like shutter and aperture
For example, going from ISO50 to ISO200 buys you 2 stops more light. Slower films are less sensitive and generally require longer exposures / more light. Faster films react rapidly, and can be used in low light situations.
Digital cameras also have a film speed rating, usually around 50ASA. Instead of buying different film for a digital camera, you can adjust the ISO/ASA, just like "real" film.
Film Speed vs. Contrast and Grain
The trade-off between slow and fast films is quality. Slow films generally produce sharper, more detailed images, while faster films often have higher contrast and grain.

Film speed uses stops, just like shutter and aperture
For example, going from ISO50 to ISO200 buys you 2 stops more light. Slower films are less sensitive and generally require longer exposures / more light. Faster films react rapidly, and can be used in low light situations.

Quality and ISO
The task of an image sensor is to register nuances in exposures - in as much detail as possible. It is also necessary to be able to hold a camera in our hands when we take photographs, which means the camera's sensitivity is also important. Sensitivity is measured in ISO values, which state how fast the image sensor reacts to light. The faster, the better - which can give problems with digital noise.
ISO values tell you how fast your camera reacts to light. With a high ISO you can take photographs with a slower shutter speed, which is often an advantage - in bad light, for example, or for exposures with flash or telephotos (i.e. with 6X-zoom).
All cameras have several ISO values to choose between but avoid using the highest, which give digital noise in the image, as seen in Figur 45.
A piece of good advice is, choose ISO 200 or lower for daily use. The quality of ISO 400 and 800 ought to be checked, before you use them in earnest. The image might become gritty and unsharp.
Read here about how you can set your camera's ISO and which values are the best.
