Recently (April, 2010), I purchased a FujiFilm HS-10.
This camera
will shoot Raw images, and comes supplied with a Raw
File Converter (RFC).
One of the good
things about the supplied RFC, is that it can also be
used to process the Jpeg images from the camera.
The HS-10
delivers beautiful Jpeg images, if it is used correctly.
At times though, they still need a little help.
In the illustrations
below, I will describe some typical step by step processes
which can be used to correct Jpeg images.
Note : This is
the second example in this series. A third example is
here
If you are not
familiar with the controls of RFC, please look at the
first example. If you wish to see the first, click
here
In this example,
I have put yellow outlines only around controls, which I
did not use in the first example.
----------------------------------------------------------------------------------------------------- |
Step One -
Opening and displaying the image
As with all
applications, simply select File/Open, and then select
the Jpeg 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%.
I then right click again, and select the 'Zoom Tool'.
This allows me to adjust the size of the image, to comfortably fit the display,
and move it around the screen.
Here, I have
enlarged the image to 33%, and have positioned it to the left of the
display.

Step Two -
Adjust the Tone (contrast)
My main
concentration in processing this image is to get a
little more life in the colours, some more sharpness,
and also more contrast.
The camera has done
a good job with the exposure. It has tried to balance
the dynamic range, and keep shadows light, and
highlights from clipping.
The end effect is
OK, but also 'flat'.
The first thing to
do, to correct this image, is to get some of the
flatness out of it.
I simply select the
Tone (contrast) and adjust to suit.
You can see the
values I have used in the illustration below.
|
 |
Step Three - Fine
tune the Exposure
The next step is to
make a slight adjustment to the overall exposure.
Simply, I have
increased the exposure very slightly to +0.10. This is
one tenth of one stop adjustment, positive.
|
 |
Step Four -
Fine tune the White balance
This child has very
dark coloured skin, and I wish to keep his natural look.
This is more a 'honey' colour, than pink. Also, his hair
should be quite black
So, here I am simply
reducing the 'magenta' cast from the white balance.
See my values below.
Original values were 6500, 3, 0.
|
 |
Step
Five - Adjusting color (saturation)
Adjusting the white
balance has helped, but I still have a slightly washed
out look, both in skin tones and background colours.
My next step is to
adjust the saturation, to restore some of the depth to
the colours.
Here, I am using the
Color tool to add some saturation.
The default value is
1.00. I have simply increased this to 1.16.

Step Six
- Adjusting Sharpness
Another step I wish
to take, is to slightly adjust the sharpness.
As this was taken at
ISO 100, I have quite a lot of latitude for sharpness
adjustment. Many HS-10 images need some sharpening.
The values I have
used are shown below. I have also selected 'Pure
detail'. It may be my imagination, but I feel this is a
little smoother than simply using 'Normal sharp'.
|
 |
Step Seven -
Adjusting smoothness using Noise reduction
An after effect of
sharpening an image, is that it can be a little too
'crisp' looking.
This image does not need
any noise reduction, here I am simply adjusting the NR
controls to help give it a little more smoothness. The
changes are subtle but help to make the image areas
blend a little better.
You
can see the values I have used below.
Note : There are
several white 'flecks' in the image. These are neither
hot pixels, nor artifacts. Simply dust on the subject. |

Step Eight
- Saving the image
Well, that
is all I am going to do. A few simple steps.
All I have
really done is to correct the contrast, colour, and
sharpness 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 am using the file
format of DSCF4001 JPG RFC Adjust.jpg. This is so I know that
it has been processed in RFC, and this is my adjusted
version.
I have also elected
to add a very small amount of extra sharpening in this
step. Here I have applied the values of 30, 0.3, 3.
That's about it. So,
I will simply click the Save button.

The
two images shown together. The original (top), and the
adjusted image.
The
changes have resulted in an image with the sort of
'depth' I saw in the original scene.
 |
Below, is the Jpeg
image as it came from the camera, and then below that
the adjusted version as done in RFC.

The image as
finished using the RFC adjustments as described in the
process steps above.
