digital cameras: color "trueness"

To make your monitor exhibit the true color of your piece, you need to run
color calibration software for your monitor. This is often a simple
procedure, and the process often comes with graphic design
software. Pantone puts out a disc with the procedure for running this
program.

Good luck

Photoshop has a program built in called Adobe Gamma Loader for calibrating your
monitor colors. But even that is kind of hopeless because even if two people
happened to both use it to calibrate their monitors, they would also have to use
the same parameters within the program to get the same results. It only really
works for a group of people in a department, for example, that all agree to set
their monitors exactly the same so they are seeing the same thing.

And if that's not bad enough, if you somehow managed to get the colors to agree,
one person would turn their brightness up or down and it would still look
different. If the world ever wants to solve this problem, probably everyone with a
monitor needs one of those pantone charts with exact colors printed on it; then we
could all calibrate to that.

CNC:

Some cameras have a "macro" mode with a fixed
focal distance for close-ups. My 500DL Olympus
has this and I have used it with general success and
satisfaction.

I'd like to bring up a related subject of great interest
to me. My work involves some "color matching".
What has struck me is that holding the original piece
next to a monitor version of the same object reveals
a lot about where things are with color "accuracy".
The digital images are "pleasing" enough, and certainly
representative and detailed enough. Color matching seem
to be another issue.

I'm vaguely aware that there is a whole world of detail
to get lost in here, that is not what I am looking for.
What I am wondering is if other people have recognized
this same problem, and what they might be doing about
it on a pragmatic basis. Is the monitor perhaps more
culpable than the camera for example? Is lighting
spectrum perhaps a critical issue? Do digital cameras
differ substantially?

I'd appreciate hearing from anybody that has fought
this good fight and learned what the issues are.

Sincerely,

Hello, George.

You can adjust the colors of your digital or scanned photos for color
trueness. I use Paint Shop Pro, but there are tons of programs out there. If
I'm not sure about the color in a photo, I bring the piece in and, as you
said, hold it up to the monitor. The idea is to get the closest match
possible to what the piece really looks like. After all, if somebody buys
the piece, you don't want them being surprised.

But you're right about monitors. There is a way to calibrate or adjust your
monitor (can't remember the exact term). I haven't figured it out yet, as,
just from the name, it sounds confusing. I'm sure it's actually very simple.
Of course, even if your own monitor is "in tune", that's no guarantee the
person who's viewing your web page will be doing so with a monitor tuned to
the same key. So, it's probably a good idea to mention this fact in a
prominent location on your page.
