Monitor/Camera/Scanner Profiles
Why colour manage?
Each device in your digital
darkroom produces or handles colour differently. The goal is to get
these different devices to give consistent colours, for example a photo
viewed on a monitor should look the same when printed.
The goal
of colour management is to improve colour predictability and
consistency. In a properly colour managed workflow a photo will look
the same from capture, viewing on a monitor and when printed (within
device limitations).
BAT Systems can help you achieve consistency by providing
custom printer profiles
, camera profiles, scanner profiles and monitor profiles.
What's involved?
The steps to improving colour accuracy are:
BAT Systems provide a camera/scanner and monitor profiling service. We do
however recommend that you purchase the tools to perform these steps
yourself. The reasons for this are:
-
Profiling your
camera/scanner/monitor requires a site visit by one of our staff. We
charge a fee based on distance from our office near Buxton in
Derbyshire. We then charge an additional fee to profile each device.
It's almost certainly more cost effective for you to buy your own
equipment to profile these items.
-
Monitors need to be
regularly profiled as their output will drift with time. CRT displays
are worse in this respect and should be profiled every week for
accuracy. LCD monitors are more stable
and don't need to be calibrated so often (once a month is Ok). If you are on a tight budget
and you do not need to send your images to other people to work on then
we recommend the Pantone Huey.
This device produces acceptable profiles but there are limitiations.
Read this review
(external link) for more details. If you do go with the Huey we recommend the 'Web
Browsing & Photo Editing' option for white balance (~6500K/Gamma
2.2). The Huey is not recommended if you need to prepare images for
other users, e.g. for sending to a lab, as you cannot tell other
operators exactly how your monitor is calibrated. Other recommended
monitor calibration tools are the Spyder 2, the Eye-One Display 2 or the Eye-One Display LT.

If you are scanning film then ideally your scanner should be profiled
against each film type that you use. For slides low cost IT8.7 profile
targets are available from Wolf Faust at
http://www.targets.coloraid.de/.
If you use a flatbed scanner we recommend the
R1 target at €10. For film scanners we recommend
the S1 pack at €70 (includes R1)
(Prices correct as of 01-Mar-2006). We also recommend that you use
Vuescan
to drive your scanner ($89.95 as of 23-Feb-2006). You need the Pro version to profile your scanner.
-
Your
camera needs profiling every time white balance changes. The easiest
way to do this is to photograph a reference target in the same lighting
as you are using for the rest of your shots. Programs like
Vuescan
are then able to generate a profile from this reference.
We recommend the C1 camera target from
http://www.targets.coloraid.de/
(€25 as of 01-Mar-2006) or a GretagMacbeth mini colour checker.
An alternative is the
QPCard
range (we haven't tried the QPCard ourselves so we can't comment on it's accuracy).
If you do need us to profile your scanner, camera or monitor please contact us at
for a quotation. As a guideline we charge £10 for each
monitor/scanner/camera profile plus the cost of a site visit based on
distance from our office.
