Editor’s note: Neil van Niekerk
of Planet Neil (www.planetneil.
com), a unique web site for digital
shooters, has some terrific advice for
a RAW file workflow. Neil shoots nearly
exclusively in the RAW file format because
of the adjustment flexibility and because
RAW is much more forgiving in terms of
exposure and color balance than the JPEG
format.
The main disadvantage to
using the RAW format is
that the files are so much
larger than JPEG files. This
means more memory space
and more resources are required
to process the files.
An appealing aspect of the
RAW format is that with
JPEGs you’d have to come
up with a system where you
keep multiple copies and
multiple backups so you
don’t overwrite your originals.
With RAW, you always
have your originals to work
on, and you can change
them without causing file
degradation.
My digital workflow is
structured around my work
as a wedding photographer.
I photograph between one
and three weddings each
weekend, and I shoot between
800–1200 images at
each wedding in RAW file
format. My digital workflow
is aimed at getting the best
possible image in a reasonable
amount of time. My
workflow also assumes that
I will convert the RAW files
in the last phase to JPEGs
for proofing.

Firstly, if you already have
Photoshop CS2, you don’t
need anything more than
Bridge and Adobe Camera Raw (ACR) for
your RAW workflow. There is much to be
said for working entirely within Bridge and
ACR; however, I tend to mix and match
various other programs in my workflow.
I shoot with both Canon and Nikon
cameras, and my workflow is slightly different
for each. I like using Canon’s proprietary
software, Digital Photo Professional
(DPP). It is an easy and fast program to use. Nikon’s software is more limited for a
volume workflow, so for volume work the
other RAW editor programs are far more
efficient.
I use BreezeBrowser Pro for my initial
workflow, and for the actual editing process,
I work with Phase One Capture One
Pro, which is an impressively fast tool for
editing images in RAW.
This workflow will certainly change over
time as software specific to RAW workflows
is developed. At the time of this writing,
things are heating up with the release
of Aperture (see article on page 66), and
the recent release of Adobe’s Lightroom
(Beta).
Workflow Stages
1. Image transfer—copy images from CompactFlash cards to hard disc.
2. Verify RAW files and rename—let
Bridge or Capture One generate previews.
3. Create back-ups to DVD and/or other
hard discs.
4. Edit RAW files—select, sort, add
metadata, and correct RAW files.
5. Production—process to JPEG for
proofing/web galleries.

The workflow is a methodical
system to make sure I always
have back-ups so I can
retrace my steps at any point,
in case I make mistakes or
there are problems.
The most important step
for a good digital workflow
is to make sure you have the
best possible exposure and
the best possible white balance
when taking the actual
photograph. The closer the
image is to ideal, the less
work you have to do in postproduction.
Keeping your exposures
and white balance consistent
for an entire sequence of images,
will greatly speed up
your workflow, besides giving
you optimum image quality.
By shooting in manual exposure
mode, all the photos in
a sequence will be the same,
so if there are any slight errors,
groups of images can be
adjusted, instead of laboring
over individual images. This
will drastically cut down on
the time needed to spend on
them in post-processing.
1. Image Transfer and
Downloading Images
Since I use a PC, I simply
use Windows Explorer to
transfer images to my computer.
Make extra sure to
download all the folders that the camera
created. It is important to copy files when
you download and not merely move them.
With Nikon files, I use Nikon Transfer,
which works very well. With Canon files,
Breeze Systems’ Downloader Pro handles
downloading the folders in Canon’s multiple
folder system very well.
With my cameras synced for exact (clock)
time, it is an easy matter to combine im-ages from both cameras into a single folder
and have them appear chronologically.
2. Verifying Images and Renaming Files
Many of the image browsers show the
embedded JPEGs and don’t show the actual
images generated from the RAW files.
It is therefore possible to have corrupt
RAW files without realizing it. Therefore,
I don’t format my CF cards until I am sure
my RAW files are not corrupt.
If I need to re-use my CF
cards the next day, I can’t
rely on programs such as
DPP, Nikon Browser or
BreezeBrowser to tell me
that my images have been
corrupted.
I like to use either Capture
One or Adobe Camera Raw
to generate previews before
I proceed. It takes some time
for Capture One and ACR
to generate thumbnails, but
the thumbnails are more accurate
than the thumbnails
you see in DPP, and the previews
are a way to verify
your RAW files.
Even though I like using
DPP because is a fast way of
editing Canon RAW files, I
can’t rely on it to verify the
images. As far as I know,
DPP uses the embedded
thumbnails, so DPP doesn’t
generate previews like other
RAW editor programs. It
is one of the aspects that
makes DPP a fast and efficient
RAW program. But if I
have to have Capture One or
ACR generate the previews
as a way of verifying my files,
I may just edit my RAW files
in those programs instead of
DPP, since the previews are
more accurate.

After verifying the images,
I order the images chronologically based
on the time the image was created. I then
batch-rename the images, using Breeze-
Browser Pro. Although numerous programs
allow batch renaming, I like BreezeBrowser
for this since it allows me to
simultaneously rename RAW + JPEG in
the same folder.
Many photographers only rename their files later in their workflow, but I like to rename
my files nearly immediately to have
more useful and recognizable names than
that generated by the camera.
3. Creating Back-ups to DVD
and/or Other Hard Discs
Before editing the images, I make a DVD
copy of the verified images, and also copy
the files to two other hard discs.
You can’t be too paranoid about backups.
Hard discs will fail—not if, but when.
It is important to be thorough and consistent
about this phase of the workflow.
Only at this point in my workflow do I
format my CF cards for the next shoot. Yet,
I still double-check to make sure I downloaded
all the folders and that I recognize
images from each card in the folder I use
for editing. I also check that the images on the computer don’t appear to be missing
any sequences.
There’s no going back once you start
shooting and write files onto a formatted
card, so you have to be 101% sure. It even
makes sense to have enough cards to do
an entire weekend’s worth of shoots so you
don’t have to re-use any cards until the following
weekend.
Now I can proceed to the actual editing
stage.
4. Editing RAW Files—
Selecting, Sorting, Adding
Metadata, and Correcting
RAW Files
During editing, start with
general settings, and then
work down to the specifics.
In other words, do global
changes to white balance
and exposure first, and then
touch up single images that
still need it.
Since we’re editing for
proofing and web galleries
at this point, it will also help
your speed and efficiency if
you aim for good, not perfect.
Apply keywords and metadata
if you want to search for
specific photos later on. This
depends on how or whether
you want to keep track of
your images. This step can
be earlier on in the workflow,
depending on the software
you work with. Keywords
are recorded in various ways,
which will also be affected
by the software. Some write
the keywords in databases.
Adobe Camera Raw writes
them to sidecar files, Breeze-
Browser Pro writes them to
the actual file.
When selecting images, it is
easier to “edit in” than to “edit
out.” I therefore select the photos I want to
keep, i.e. those that go to proofing and for
the galleries. I create two folders—“RAW
selected” and “RAW discarded”—and sort
my images accordingly, by adding check
marks to the files I want to keep.
I might delete images that just don’t
make it, but generally I put the non-keepers
in the “discarded” folder, in case I need to go back.
Selecting and sorting the photos can be
done during the editing process, since it
is as much effort correcting exposure and
white balance on four images as it is for 20
images.
I often use BreezeBrowser to tag images
I want to keep, but I’ve found the slideshow
feature of Adobe Camera
Raw to be exceptionally
fast with this step.
Also during the editing
process, rotate images,
if needed. This can be
done with any of the programs,
so I use whichever
program I am editing
the RAW files in.
I then edit the RAW
files for white balance
and exposure. For maximum
efficiency, it is essential
to adjust entire
sequences or groups of
images together.

It is usually better to
start with the white balance
first, since adjusting
the white balance can
often affect the exposure
if you look at the various
channels. If an image
appears very warm and
shows overexposure in
the red channel, then
correcting the white balance
could very well stop
the exposure warnings
in your editing program.
Do a rough white balance
with the white balance
tool (eye-dropper),
and then fine-tune with
sliders. There are tools
like WhiBal Card that
will help white-balance
correction in post-production,
but mostly I
click on white shirt collars
and such to bring
my images close to correct white balance.
(Of course, your monitor must be calibrated!)
Also, adjust contrast and brightness as
part of exposure correction.
Overexposure warnings will help in judging
exposure. With Canon’s DPP, this is a
breeze, since you can highlight multiple
images and drag the exposure slider, or change the white balance by selecting
another white balance or adjusting the
color wheel. Because the thumbnail in
DPP isn’t an accurate reflection of the
image once it is adjusted, your images
need to be pretty good in terms of white
balance and exposure. But as a good
guide to your final image, this way of
editing is hard to beat in terms of speed
for a rough edit.
You can then open any image in the
editor window for an accurate adjustment.
You can then copy and paste the
overall adjustments to any of the other
images. This is where DPP is limited in
comparison to Capture One Pro, where you can select which adjustments you
want to copy over. With DPP you can
only copy overall adjustments. Hopefully,
future versions of DPP will consider
this.

Other RAW file editing tips:
• When adjusting underexposed images,
an S-shaped curve may hide shadow noise.
• Sharpening is left
as part of the conversion
to JPEG, since resizing
might be involved
in generating proofs or
images for web galleries. Either way it is better to
have less sharpening in
the initial workflow.
• Noise Reduction is
dependent on camera
make and model and
chosen ISO.
• You may want to
convert some images
to black and white or
sepia. DPP is especially
great for this, and it offers
various filters that
will help brighten the
skin tones, akin to how
you would’ve used an
orange or red filter with
black-and-white film to
brighten skin tones.
• At this point I might
also crop some of the
RAW files to improve
composition. Capture
One and Adobe Camera
Raw both have brilliantly
fast ways of applying
crops to multiple images.
So if you routinely crop
large numbers of images
to 4x5 or 8x10, then a
RAW workflow will save
you considerable effort.
• Copying the crop
to multiple RAW files
is faster than doing the
same for the JPEGs in
Photoshop. You can also custom crop in
ACR for web-sized images.
5. Converting RAW Files to JPEG
At this point I should have all my images
corrected for white balance and exposure
and even some of them cropped. I will now make another back-up of the RAW
files—this time of the corrected and
edited RAW files.
The next step is to convert RAW to
JPEG, via batch process.
If you’re using Adobe Camera Raw,
you could use actions to convert to
JPEG, but saving directly from ACR
is much faster, and it works in the
background.
Batch processing the RAW files to
JPEGs can take a while, depending on
how many images you are processing
and your computer’s processing speed.
I normally perform this function overnight
so the time it takes to process the
iamges isn’t a problem.
Next I will burn a DVD of these
JPEGs and keep copies of the converted
JPEGs on one of the external
hard drives.
I don’t bother converting to TIFFs
because all the potentially destructive
correction and editing work was done
on the RAW files already, so quality
is still very high. Also, there is still the
option of going back to a specific RAW
file should there be a quality problem.
At this point, the initial RAW workflow
is complete, and the JPEGs can
be sent off to the lab for proofs, or web
galleries can be created.
Excluding the time the software took
to generate the previews, I’m usually
able to finish editing a wedding within
three hours. Even though all that
sounds like a lot of effort, with some
practice it becomes a fast, yet completely
reliable way of working with
digital images. And in shooting RAW, I
have the flexibility of changing most of
the settings again.
