Last
Month….
Well
a couple of months ago we had another look at the world of computer
graphics and image manipulation. Someone once said that the
photograph never lies. Well unfortunately that little piece
of wisdom has long been consigned to the rubbish bin. In this
day and age of ever more powerful home computers and software
to go with them, the worlds of photography and digital imaging
have grown closely together and each works hand in hand with
the other.
The
subject of our recent meeting was around layers and selections
and how they can be used to create, improve or enhance original
photographs or scans as well as your own digital photographs.
Remember armed with a reasonable scanner you can scan old photographs,
negatives and even transparencies into your computer for further
manipulation – even that old faded Edwardian photograph
of your ancestors is now fair game for the image manipulator.
For
the purposes of the presentation we used Adobe Photoshop CS2
but any graphics package that supports layer manipulation such
Adobe Photoshop Elements or the excellent and FREE Gimp will
do the same sorts of tasks.
Getting
your head around the concept of layers can be a little daunting
but once you understand the principles the rest of digital imaging
gets a lot simpler. So what are layers and where do they fit
into the world of digital imaging. This is where the purist
photographer throws up his or her arms and shouts foul or something
not printable. However, film photographers have been manipulating
their pictures since the dawn of photography and many are the
dark secrets that were performed in the quest for that perfect
photograph in the darkroom cupboard under the stairs. So now
is the turn of the digital imagers.
So
back to Layers. If you consider a picture as a series of separate
components all brought together to produce the final image then
can begin to see where we are going. Layers in Photoshop have
developed greatly with each new version and there are all sorts
of manipulating techniques available that may not be found on
less pricier software.
Making
global changes to your image such as contrast or colour adjustments
do not require layers but when you want to adjust only specific
areas life becomes so much easier with layers. Layers will even
allow you to change the size, position and colour of separate
parts of your image independent of the rest of the image. To
help with this we have various forms of layer available to the
imager.
The initial image is always called the Background Layer and
is the basis of the final image. This layer is usually locked
to prevent any accidental damage to the original image. We can
then add layers above this and produce a composite image. Each
additional layer is called an Adjustment Layer and these are
used to build up the final image. We also have Mask Layers that
allow you to mask out certain areas underneath on lower layers
allowing tight control of any adjustments. There also a whole
range of Blending Modes available that allows the imager to
be creative and ensure that a new feature blends in effectively
with the background.
From the image you can see how the composite picture can be
built up. All the various image tools are available to any adjustment
layer which can also be locked together to allow more global
adjustments.
At
the presentation we showed a short video on how to create a
very effective composite image out of various shots taken at
the Great Central Railway in Loughborough. The video showed
the various techniques available and resulted in a very professional
quality image at the end.
Our
challenge was then to recreate this image step by step so that
we could understand the techniques of layer manipulation and
blending for ourselves. Although we did not have the time necessary
to create a perfect image, we were able to get a good rendition
and show how easy it is to create some pretty stunning images.
The
final task is always to flatten all the layers down into the
image if you want to print out the finished article. In Photoshop
you can save the image in its native .PSD file which retains
all the information and layer adjustments so that you can return
to the project at any time. These files will of course be quite
large.
Layers were never available to the original film photographers
and some may say that we are taking digital photography too
far and into another medium. That is another whole debate for
others to pursue.
I
hope everyone who was present enjoyed the evening and were given
some food for thought for the next Photo Competition.

Topical Tip of the Month …
Are
you inundated with spam emails? My guess is that you probably
are. We do not like spam emails, but a lot of what we receive
is self inflicted. Whenever we contact a website and perhaps
place an order online or make an enquiry we give that website
the opportunity, even if we have diligently ticked or ignored
the box referring to future contact with them.
All
is not lost and it can be very easy to get rid of unwanted emails
at a stroke. Just open up the offending spam email and go to
the bottom of the page and click UNSUBSCRIBE etc and hope they
will honour your request.
It
may not always work of course but I have managed to get rid
of 10 of these reoccurring spam mails already. Hope it works
for you too.
