Recently (April, 2010), I purchased a FujiFilm HS-10.
This camera
will shoot Raw images, and comes supplied with a Raw
File Converter (RFC). This is 'powered' by SilkyPix, and
is similar to the SilkyPix Developer Studio, albeit with
a little less functionality. Still, it is very usable.
I normally use other applications for processing
Raw files. At present (May, 2010), RFC, and SilkyPix
Developer Studio (or Pro), are the only
applications which will support the HS-10 Raw files.
The HS-10
delivers beautiful Jpeg images, if it is used correctly.
If shooting Raw, much more control can be had over the
resultant output. Particularly in terms of exposure,
contrast, sharpening and, perhaps most importantly,
noise control.
Processing
raw images can seem a little daunting, and confusing,
for a first time user. So, I have put together some
notes about a set of process steps which can be used to
get good results from RFC.
In the illustrations
below, I will describe the typical step by step process which I use for
converting, and adjusting, a Raw file from the HS-10
using RFC.
The original
Raw file, I have used in this example, is available
here if you wish to
download and play with it yourself.
Have fun.
Note : This is
the second example in the series. If you wish to see the
first, click
here
If you are not
familiar with the controls of RFC, please look at the
first example.
In this example,
I will not put text on the image, unless I am talking
about a new/different control from those used in the
first example.

----------------------------------------------------------------------------------------------------- |
Step One -
Opening and displaying the image
As with all
applications, simply select File/Open, and then select
the Raw file you wish to work with in RFC.
Once the file is open, right click on the image and select
the display size you wish to work in. To start, I normally select the size as 25%, and then enlarge the
image to comfortably fit the display.
Here, I have
enlarged the image to 32%, and have positioned it to the left of the
display.
My main
concentration in developing this image is to correct the
white balance (WB), and also to try to lighten the
background, whilst keeping noise levels at a minimum.
|
 |
Step Two -
Correcting white balance using the 'Gray balance tool'
A different, and
often quicker way to correct WB, is to find an area, in
the image, which should be neutral gray. In this image
there are several areas which can be measured to achieve
this.
Simply click on the
Gray balance tool.
|
 |
Step Two (continued) -
Correcting white balance using the 'Gray balance tool'
Once I have selected
the Gray balance tool, I look for an area in the image
which I am certain should have neutral values.
You can see that when I clicked in
this area, my WB has returned to a more normal look.
Note : Middle gray is described
as having RGB values of 128, 128, 128. This pretty much
equates to the 'midtone's values which PhotoShop, and
other editing applications use.
The RFC Gray balance tool is
looking more for neutral gray areas, or areas which
should have equal RGB values, and still fall within the
'gray' spectrum.
In practice, I have found
that anywhere from approximately 40, 40, 40 through 165,
165, 165 can be used to balance colours in neutral
areas.
Tip : If you click an area and
the desired effect is not realised, select 'undo' and
then select Gray balance tool again, and resample.
Sometimes it takes a couple of attempts.
If
you get the WB totally messed up, simply click where it
says 'Manual' and then select Fine (5200K) to go back to
the default settings.

Step Three -
Reduce the contrast
As with my previous
example, I will select 'Low contrast' to lower the
overall contrast in the image.
This helps to
flatten the tones in the image slightly, and also helps keep any
noise to a minimum.
Remember, the more contrast you
add in an image, the more noise you will accentuate.
There is nothing wrong with using the contrast tools, only
later in our process steps.
|
 |
Step Four -
Adjust noise reduction controls
Again, as with my
previous example, I have negated all the noise reduction
controls.
Here, however, I
have then applied full (100%) False color crtl, and also
35% Noise reduction.
With this image, I
am very mindful of trying to keep the noise (upper
right) to a minimum. That is why the image is now
enlarged, and displayed as it is.
Note : The most
'savage' noise control is the one labelled 'Noise level'
in the Noise canceller window. I do use it, but only at
values of one, or two. Have a play with it and see what
effects it gives.
Best to leave it
off, unless absolutely required though.
|
 |
Step Five -
Adjust sharpening
Here, I have applied
the sharpening levels as can be seen in the Sharpness
controls window.
|
 |
Step Six
- Using the Highlight controller, and Fine color
controller
I am now going to
use two controls which were not used in my first
example.
These are the
Highlight, and Fine color controllers.
Here, I have both
open and I have selected 'Tender green emphasis', in the
Fine color controller. This gives a slightly more green
tone to the image.
Note : If you run
your mouse over any of the descriptors, the screen will
change to preview that selection.
|
 |
Step Six
(continued) - Using the Highlight controller, and Fine
color controller
Here, I have
selected the Highlight controller, and 'Luminance
priority'. This helps to 'lift' the image slightly.
Note : If you run
your mouse over any of the descriptors, the screen will
change to preview that selection.
|
 |
Step
Seven - Adjusting the exposure
At this
point, I wish to 'lighten' the image a little.
Here, I have simply
applied an EV compensation of +0.20.
Note : In my
first process example, I showed how to use the
Shadow/highlight warning control. As I work through this
image, I am also switching that on/off to see what some
of my adjustments are effecting.
In reality, I
will never lift all the shadow areas, nor am I trying
to. I'm sure you can see though, that as we work through
the image, the shadow areas are coming out. The trick is
not to let the highlights 'clip' as we do so. |

Step
Eight - Fine tuning contrast and white balance
As I have worked
through the image, I am sure you can see that the steps
I have taken have had an effect on the contrast, and the
colour of the image.
So, at this
point, I wish to do a little fine tuning of the
contrast, and the white balance.
Here, I have
reopened the contrast (Tone) window, and have adjusted
the 'Contrast center' control to 0.55. The original
setting was 0.46. This simply helps to add a little more
contrast to the image.
|
 |
Step
Eight (continued) - Fine tuning contrast and white
balance
Similar to fine tuning the contrast, I also wish to do a
very slight adjustment to the white balance.
Here, I have only adjusted the 'Color deflection'
control to a value of 1. It had a value of 4 prior.
Adjusting this control, affects the midtone colours in
the image.

Step Nine
- Saving the image
Well, that
is all I am going to do. It may seem like a lot of
steps, really it is few.
All I have
really done is to correct the white balance, get
the sharpness and NR under my control, and 'balance' the
contrast of the image.
Now I am
going to save the image.
To do this I
simply select the Development icon and the 'Save As'
options window will open. I have also clicked the
'Preview button so I can preview any steps I take here.
I am using the file
format of DSCF3316 RFC Final.jpg. This is so I know that
it has been developed in RFC, and this is my final
version.
I have also elected
to add a very small amount of extra sharpening in this
step. Here I have applied the values of 20, 0.3, 3.
That's about it. So,
I will simply click the Save button.
Below this
illustration, I have put the image as first opened in
RFC, and then followed by the final image. After that, I
have put the Jpeg image which came from shooting Raw +
Jpeg.

in RFC, and with the RFC default settings.
