java disabled or no main menu showing above - use links
Note - Since the build of this quite basic site long ago, technology has advanced - also some external links may have expired, but basic principles still apply. It was put together initially to help folks in a forum, thus some pages explaining how to post pictures are still included, even tho they may be out of date for exact method.
is set up for 800 x 600 resolution,
to cater for those few
who may be limited that way. Scripting is best enabled.
| This was put together to try and help those,
as yet not fully into digital image work or
even just starting, and hope they will gain
There is no great attempt so far to be bothering
with too many frills - this is about information
and I won't apologize if some seems excessively
''basic'' - it is designed to try and help
all levels, from total newbie upwards!
FYI ... some example pics are my daughter
... many, many years ago! I make use
of this file set because I prepared it some
time ago for similar usage.
try to cover things in a fairly logical manner,
giving initially a brief description of the
content (see below) so you can ultimately
choose which to look at while using the links
on the left, trying in part to have a sequence
whereby we can progress from some theory and
basics, to more advanced matters and techniques.
Note - this is NOT meant to be encyclopedic!!
Purely an attempt to aid understanding. Some
aspects may not interest you at all but are
included for completeness' sake.
In many of the sections listed, I have tried
to utilize just one main image for the examples
- in the hope that this consistency will better
show and contrast the various points being
Because obviously much can be best explained
or demonstrated through actual images, this
could produce a fairly heavy image burden
- to minimize this, they will be well compressed
and size limited for space-saving, and also
pages kept small enough individually to avoid
too heavy a download time penalty. If higher
resolution images seem needed at any stage
- then I will leave them separately available
so you can access them when needed - this
is mostly to help dial up users.
the most popular and pretty much ''de facto''
application for image work tends to be Adobe's
"PhotoShop® Version 7" or
higher, I use and have used for some time
now, Micrografx's application "Picture
Publisher® Version 8.01" much more.
Partly because I am long familiar with it
but also because it has for me a much more
user-friendly interface. ''Whatever works
Other packages, such
as "Paint Shop Pro®", now
in it's umpteenth incarnation, are also
of great value and have plenty of power
- the principles involved being all pretty
much similar across the various application
platforms and most packages now do most
things, more or less efficiently.
Simple adjustments and size changes can
also be done quite efficiently with IrfanView,
a small and freeware application........
very adequate for the average user who's
main prerequisite is resizing.
The sequence listed below approximates a
fairly logical approach to this subject
if you want to read through stage by stage
but of course - feel free to view as you
quick rundown of what is hoped are some
of the initial things you may wonder about
when starting off with images, scanning
is a digital image made up? What is resolution?
What are the image formats? We look at these
and associated matters, to investigate the
"ground level" aspects.
JPG format has already been discussed
but, here we look at examples to illustrate
the effects of over compression, compared
with a more moderate level.
have a look at how colors are produced, displayed
and influenced - the three 'models'.
we concentrate more specifically on how
the colors relate to the computer, the printer
and also dig a little deeper into the RGB
software tools can we use on our images? Here
we take a look at the main choice of implements
you might have at your disposal for image
processing and adjustments.
we have an image - what can we do to alter
it? We look at some examples of major changes
that can be made, and how to go about achieving
exploiting the .GIF format, we can produce
useful animated effects. Relatively simple
to achieve...... and may be of interest.
refers to the "manufacture" of images
via a graphics application - of which there
are many. ''Digital painting'' if you like.
looks at resolution, how it affects file sizes
etc and explaining the DPI relationship. It
is worth gaining a grasp on these two.
brief look at scanner matters ...... just
some general considerations about the unit
itself and its useage.
is where we look at the relationship between
the scanned image, and what is required for
use in your printer. The basic function of
your inkjet printer is explained and how that
can affect choices.
are a number of specification data quoted
for cameras which can be difficult to interpret.
This tries to explain a few and, also make
some broad recommendations.
with a wish to learn or "brush up"
on your binary and hex' - have a look here
to take a quick run through the two number
systems. Not essential reading, but can help
understanding on color values. (Opens new
some basic suggestions as to how you might
best achieve reasonable results..... often
using quite simple equipment.
example is included here to further emphasize
aspects of file size and image size when considering
taking a digital picture, there may still
be changes required to help balance the image
for color and brightness, and even ''touching
up'' to remove artifacts.
one thing to use the camera and get some useful
images ...... another very often to know how
best to let others see them on the board.
We explore some general considerations.
we look at the methodology of getting those
images on your hard drive on to the board,
as attachments for all to see.
you need to show an image from another site,
or post your own already hosted somewhere
- this is the way to go.
where we run through things like 'f' stops,
shutter speeds, depth of field, and how they
are all interelated
further attempt to clarify the matters in
the last section - here are diagrams to make
it more visual.
categories on offer should help illuminate
you on the whole subject of images, although
it is of course a very large field - but
I have tried to cover enough of the main
elements to at least I hope give you a feel,
following which an excursion into the realm
of books and the web can add more to aspects
you may want to study in further detail.
