| 1 CAMERA |
If you
plan to edit and print
your own photos
change your camera color space setting to Adobe RGB. It probably
is on sRGB if you have never changed it. If you are happy with your camera's images then leave the setting on sRGB. Read your camera manual to see how the manufacturer tells you to deal with color spaces. Canon 10D, 20D, Rebel and XT users will want to read specific info in your user's guides about this option: page 62 in the Rebel XT350 manual; page 58 in the 10D manual; page 56 in the 20D manual. |

Make
sure you have left the
saturation, contrast, and sharpness settings in the default mode on
your camera. Don't boost or cut anything in your camera, let the
software do this step. |

If you
want black and white
prints - shoot in color and adjust the color image later on to obtain
the best black and white. |
|
| 3 MONITOR |
Use some
type of monitor
calibration tool. Use Adobe Gamma, which is located in the
Windows control panel area to adjust contrast, brightness, and colors
if you have Adobe software. This utility self installs in your
control panel when you install Adobe software, it's free, just use
it. If you can afford a third party colorimeter, then use that
device to measure and correct your monitor instead of Adobe Gamma. Note: If your monitor is not accurate then you are making inaccurate decisions in your editing software regarding contrast (tonal information), color saturation, and hue changes. And, don't try to compensate for this inaccuracy by skewing your printer color controls. |
Colorimeters (Colorvision, Pantone, Monaco, etc.) |
| 4 MONITOR |
If you
are using a laptop PC or
Mac, or an LCD monitor on your desktop pc, then ask me for help in
setting up color. Do you know how to adjust your laptop pc's
brightness and contrast? My experiences so far have been marginal
in trying to make an LCD monitor look as good as my better flat screen
LaCie or Sony CRT's. Just my
opinion.... |
Setting up your monitor correctly |
| 5 SOFTWARE |
Read
your software help
information to see how the manufacturer suggests you deal with setting
up color preferences. Photoshop, Elements, Paint Shop Pro,
Microsoft, etc. all will tell you something a little different. My experiences so far tell me that Adobe is all over the place when it comes to saying and doing color management between their different pieces of software. Photoshop CS2 has the clearest info to date. |
|
| 6 SOFTWARE |
Get a
reliable test image and
make a test print to see how close you are to a good print. Don't
fix things until you know what you are fixing. Test
Images. When you first open an image file try doing a Save As command and look around in that dialog box for information as to what color space you are about to tag your image with. Many times this will be a surprise and you'll find that even though you thought you were tagging your file with Adobe RGB - if you intend to print the image - it's not showing up that way in the dialog box. In most software the next step is to go to the Color Settings preferences dialog boxes and reset your options to the color space you want. sRGB for screen and web output; Adobe RGB for printer output. |
Photoshop
Elements Color Help Photoshop CS2 Color Help |
| 7 SOFTWARE |
When you
edit your image, if you are using
Photoshop CS2,
then start checking your output quality before you print by using the View
> Soft Proof options. If you are not familiar with Soft
Proofing then go to Photoshop's help command and do some reading on
this. This option let's you see how your image will look based on
your printer, your paper you plan to use, and your existing adjustment
layers. Consider flattening your image then adding one more
adjustment layer while soft proofing to see if you need to boost or cut
saturation or tonal levels. Note: Soft Proofing is not available in Elements. |

paper profiles for the type and brand of paper you will be using.
I know this may put many of you to sleep, but stick with this step. Here is information for Kodak papers just as an example. I use only Epson papers, but let's not get too hooked on Epson if Kodak papers will provide the quality you need. Kodak professional inkjet papers separate pdf's for PS and El. Note: The following is excerpted from Kodak's web page: What is a color profile? A color printer profile is a small software file that describes how ink interacts with a specific type of paper, within a specific printing system. In this case, your printer. Using the right ICC Color Profile for your printer is one of the easiest steps you can take toward better prints. Your print driver will use the profile to adjust the output of ink to match the colors, contrast, and brightness in the picture file. The result is better, more consistent, even amazing prints. Your printer came with profiles that are specific to the manufacturer’s paper, but all papers are made slightly (or dramatically) different. By using the profiles we made specifically for your printer (along with the correct Printer Driver settings), you’ll get the best possible prints on KODAK PROFESSIONAL Inkjet Photo Paper. If you’re looking for color predictability and consistency, download the profile for your printer and operating system, and get the results you expect – every time. |

Learn
how to let your software
determine the colors your printer will use to make the print, not your
printer color controls. Sounds weird right? The idea here
is to literally turn off the color controls in your printer and let
your software manage this process. You are still going to select
the paper type, paper size, dots per inch of ink spray (usually 1440
dpi or 2880 dpi with Epson's), speed of printing, edge smoothing, etc.
in the printer dialog box, but you are going to turn off the printer's
color controls. |

So which is the best rendering intent for
digital photography? In general, perceptual and relative colorimetric
are best suited for photography because they aim to preserve the same
visual appearance as the original.
The decision about when to use each of these depends on image content and the intended purpose. Images with intense colors (such as bright sunsets or well-lit floral arrangements) will preserve more of their color gradation in extreme colors using perceptual intent. On the other hand, this may come at the expense of compressing or dulling more moderate colors. Images with more subtle tones (such as some portraits) often stand to benefit more from the increased accuracy of relative colorimetric (assuming no colors are placed within the gamut mismatch region). Perceptual intent is overall the safest bet for general and batch use, unless you know specifics about each image.
The following table summarizes the
characteristics of pigment and dye inks:
Characteristic Pigment
Ink Dye Ink
