ColorWasher
& RAW Converters
ColorWasher only works on RGB images
that were opened in a graphics application, because it doesn't
handle RAW data. So you need a RAW Converter to import a RAW
file into a graphics application or save it to an RGB file.
Although all RAW Converters offer a color correction feature,
that doesn't make ColorWasher obsolete. ColorWasher can be useful
even if you work with RAW files. ColorWasher manages to color
correct photos much better than some RAW Converters, it gives
you more flexibility and options for fine tuning the image and
can produces more consistent results across a range of images.
If you want to correct a RAW file with
ColorWasher, you should do as few adjustments in the RAW conversion
software as possible. For example keep the color correction
setting to camera defaults and don't raise brightness and contrast.
Also make sure that the image is converted to 16bit to achieve
a better quality in ColorWasher. On the other hand, if a RAW
Converter already does a quite good job, but needs a final touch
up in ColorWasher, it is better to run ColorWasher on the image
that was already adjusted in the RAW Converter.
Here are some examples
that demonstrate that it makes sense to use ColorWasher in addition
to your RAW conversion software:
|
Original Photo
(Camera Settings)

This is the original photo when
converted with the camera settings. The manual white balance
feature of the camera was used before taking this photo,
but it only turned the orange cast from the street lamps
into a green cast.

Adobe Camera RAW (ACR)
The Adobe Camera RAW plugins is delivered
with Photoshop CS and Photoshop Elements 3. Two years ago it
was also available as a separate product. Although it is quite
a good tool, it sometimes has problems with color corrections.
It can fail in some cases or produce color results that don't
look that natural.

| This correction
was done in Adobe Camera RAW (ACR) in Photoshop. ACR didn't
manage to remove the color cast from the snow. The best
it managed to do was to create this light pink cast. |
After converting
the RAW file with ACR using the default camera settings,
ColorWasher was applied to it. Unlike ACR it managed to
remove the color cast completely and gave the night sky
a nice royal blue touch. |
Paint Shop Pro 9 - Camera RAW Data
The RAW import feature of Paint Shop
Pro 9 is limited in two ways. First of all, it can't produce
16bit images, because Paint Shop Pro doesn't support them. Secondly,
it only has very few features and a very limited color correction
feature.

| The Incandescent
option of the Camera RAW Data produces the least strong
color cast in this case. The As Shot setting produces an
image that has a much stronger color cast. |
After converting the RAW file
with Camera RAW Data using the Incandescent settings,
ColorWasher was applied to it. After some tweaking ColorWasher
managed to make the snow white. Unfortunately the colors
were drained a bit by the extreme saturation in the starting
image, which needed to be reduced in ColorWasher.

DCRAW (Freeware)
DCRAW is a command line tool that is
used by several freeware RAW Converters. It offers only a few
adjustment options. In this case we used RAWDrop
to convert the RAW files.

|
| We used RAWDrop
with a Red Scale value of 0.3 and a Blue scale value of
1.4 to produce this image with a cast that is less bad than
with other settings. The Auto WB and Camera WB settings
produce a very bad result. At the bottom of the image you
can see that the highlights were blown. |
ColorWasher
was run on the TIF file that was produced by RAWDrop.
The result could be considered almost as good as running
ColorWasher on the Adobe Camera RAW image (see above), but
the blown highlights that were created by DCRAW are a serious
problem. |
Silverfast DC Pro / DC VLT
Silverfast DC is a plugin for converting
RAW files among other things. The VLT version misses some useful
correction features of the Pro version, but the Pro version
on the other hand is very expensive.

| This result
was achieved with DC Pro. It looks quite good, but DC Pro
doesn't manage to completely remove the color cast from
the snow. There is still a light brown cast. DC Pro can
create discoloration on blown highlights, but that was avoided
here by raising the Exposure slider. |
ColorWasher
was run on image on the left and managed to remove the remaining
cast from the snow. |
Bibble Pro
Bibble Pro is a applications as well
as plugin for RAW conversion. It offers a lot of features and
is intuitive to use.

Capture One, Breeze Browser and
SharpRAW
These three tools have color correction
features that are relatively good, so you probably won't need
ColorWasher very often with them. Nevertheless, if you don't
want to miss ColorWasher's user-friendliness, flexibility, automatic
correction and color effect features, you should stick to ColorWasher.
