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 third example in this series.
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 other examples.
----------------------------------------------------------------------------------------------------- |
|
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 One (continued) -
Opening and displaying the image
My intention with
this image, is to crop it once I have finished my
process steps.
I cannot do the
cropping in RFC, but will use an external image editor.
One alternative is
to use FastStone. This is a free application.
So, here I have
increased the image magnification to 50%, and positioned
the image to display how I envisage it as finally cropped.

Step Two -
Adjust the Exposure
My main
concentration in processing this image is to get more life in the colours, some more sharpness,
and also more contrast.
The scene had much more 'depth' to
it than this. However, at the same time, I wish to keep
the 'light' in the image.
So, my first
adjustment step is to increase the exposure.
Here, I have applied
a value of +0.40.
Note : The reason
I am doing this is that I know my next steps will tend
to darken the image more. I can always tone it down, if
needed.
|
 |
|
Step Two (continued) -
Fine tune the Exposure
By clicking the
Exposure bias icon, I can fine tune my exposure values.
Here, I have added another +0.05 value which brings my
overall value to +0.45.
|
 |
|
Step Three - Adjust
the White balance
I wish to warm the
image a little, so have increased my Color temperature and Dark adjustment.
I have also decreased my Color deflection. This is to
remove a slight 'magenta' cast.
See my values below.
The original values were 6500, 3, 0. These are the
default values.
|
 |
|
Step Four -
Adjust the Tone (contrast)
My next step is to
adjust the contrast of the image.
The values I have
input, have increased the overall contrast, without
increasing the effect on highlights.
|
 |
|
Step
Five - Adjusting color (saturation)
Adjusting the
contrast has helped, but I still have a washed
out look with no colour depth.
My next step is to
adjust the saturation, to restore 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 1.40.
Note : This is
quite subjective. I want 'pop' in the image. The colours,
in the original scene, were not muted.
|
 |
|
Step Six
- Adjusting Sharpness
Another step I wish
to take, is to increase 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. Some
more than others.
Here, I have been
quite aggressive with the 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'.
Note : You can
probably see that this has also increased my noise
levels. As my intention is to print this at no larger
than A3, I am not too concerned. The print process will
smooth some of it out.
However, in the
next step I will tackle some of it.
|
 |
|
Step Seven -
Adjusting smoothness using Noise reduction
An after effect of
sharpening an image, is that noise will also be
sharpened.
The fact that I will
crop this image, means I do need to pay some attention
to this noise increase.
You
can see the values I have used below.
Note : Most
times, there is no need to be too aggressive with NR, as
the print process will smooth a lot of it. Again, quite
subjective. |

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 DSCF2923 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.
 |
|
The image as
finished using the RFC adjustments, and cropped to my
final dimensions.
Note : I have also removed a couple of small white
specks - Not in RFC though.
