I've registered in a ceramics class again, having done enough PT to get my
back to the place where I think I can do small work. I plan to do a lot of
glaze experimentation, photograph it and put it on my website (not yet online).
One of the issues I have is how to render the colors accurately. In my old
black and white film photography days, I had a gray/grey scale card to
calibrate the process.
I'll be buying a new digital camera to do this and wonder how I can
calibrate it? Do I get one of those Pantone color card sets and photograph
them? And once I've done that, how do I adjust the color in the digital
image in order to correct them? More software no doubt.
TIA and cheers, Linda

Linda,
Buy a very good digital camera for starters. Adobe Photo shop (included for sure if you are buying canon) very well may come with it. Any image editing software will allow you to change your color so you can match it exactly. If you have a very good camera and tweak its settings, you will not have to change the color in post editing.
As far as monitors--they change their color over time and there is no way to make sure everyone's monitors are calibrated--even just changing your brightness and contrast on your monitor, the kind of lighting in the room where the computer is, etc, etc. I've looked at my site on many different computers OS's (MAC, PC, LINUX) and browsers--it looks different on every one. So, you can only do the best job you can do.
I am giving a photo and clay workshop at El Camino College in California (Neil Moss is the instructor there) in Late October or early November--we are still figuring out the dates. How far are you?

The term for this is "color management". Essentially, you create a "profile"
for each device: camera, computer monitor, and printer. The camera is often
skipped, though, since the image will be readjusted in processing anyway. It
is, however, essential for you to calibrate your monitor and, if your are
going to print the images, your printer.
DataColor appears to be gaining a lot of popular support for their color
management products. They have created a number of different products to
address the needs of different users. Most people do not require the
accuracy needed in a prepress house and the products are layered so that you
can choose what you need and can afford.
DataColor has a device called the Spyder (with associated software, of
course) that measures the colors displayed on the screen and corrects them
to a standard. The same device (I think) can then be used (with an upgraded
software package) to calibrate your printed output.
It's a pain in the butt, but it's the only way to get color accuracy and
consistency.

Hi Linda,
One thing to consider is that people's monitors are often calibrated
differently. This makes displaying accurate color to others very
difficult.
I personally would just look at the photos and look at the pieces and
say, yes, that looks about right (or not). Sometimes the software that
comes with the camera can do color balancing fairly well. Otherwise,
it's Photoshop (expensive) or the (usually) free lite version. As I
remember, though, the lite version of Photoshop is very limited in file
formats you can save to, and that may be a problem without a format
converter program. There is a format converter called Graphics
Converter that might just do the trick. It can be downloaded of the
web - costs about $20.

Linda,
For the most part, there is not much you can do to adjust a digital
camera aside from bracketing the light. Some cameras allow you to
compensate for differing light sources such as incandescent, florescent,
sunlight, lamps, etc. Photohop is the best tool around to work with
digital images. It has a built in program to adjust your monitor color
and contrast. You can sign up for expensive classes to get the hang of
all the tools but a much more practical way is to get a copy of the
"Adobe Classroom in a Book" for the version you are working with. It
goes through the software step by step with examples and instructions
including the endless list of shortcuts. With the book, you can deal
with everything or select just the tools and processes that you want to
use. With Photoshop, you can get great print results yourself or take
the work to almost any print shop for great results.
