Part
5 - 1 :-
Converting a colour image to black and white.
In this part, I am
using some specific tools to convert an image to
black and white.
Technique #1 -
Simple desaturation followed by adjustments
|
|
This is quite
straightforward and there is nothing wrong with it. You
will need to do some further adjustments to get the best
effect though. If you want a simple routine, or are not yet
fully confident with editing, then try this first.
Note : This is not the best method for skin tones. For
simple conversions where skin tone is dominant, skip to
Technique #3
The original
image. |
 |
|
Step 1 -
Select Desaturate |
 |
|
Once you have
selected Desaturate, the image will look something like
this.
This is a 'flat white' coffee but it really does
look too flat !
Basically, all
we are doing is stripping away any, and all, colour
information.
If you now go
to
Part 1 or
Part 2 you can use the
techniques described there to get some better contrast
and level to the image. |
 |
|
The image here
shows the effect after I have applied Desaturate to the
image and then applied a High Pass filter and the other
techniques as described in
Part 1
You
can also try adjusting your converted image with Levels,
Brightness/Contrast, etc. |
 |
|
Another simple
way to do conversions, is to use an 'off the shelf'
action, or set of filters.
There are many
available and I have included some links at the bottom
of the page. One of my favourites is Virtual
Photographer (VP).
This is a free
suite, of colour and black and white, filter profiles
and you can even create your own profiles very simply.
Once downloaded,
you simply click on Filter and select. |
 |
|
Next, you
select the profile you wish to use from the top drop
down menu.
You can also adjust any of the
presets and then save the results as your own profile(s).
To re-open your own profiles, you simply click Load at
the bottom. there are also many, many free profiles you
can download with VP. Try it, it's fun ! |

The image
below shows a comparison between VP (left) and the image
used in
Technique #2 - Using the
Channel Mixer
Here, I have
used 'Hard Steel' and then toned it down a little after
conversion and desaturated the colour. The VP version
displays more noise than the mix method. Hard to see at
this size though. |
 |
|
Pretty much
that is it. I hope you find it beneficial.
Remember, do NOT
save over your original file. Use 'Save As'.
There are hundreds
of ways to post process. This is just one technique and
I find it works well for many images.
Try it out and
have fun. Be sure to try different values in the steps
as this will provide you with a wealth of 'self-learned'
views of how the values affect the outcome.
