The most important part of any presentation is the
content, not the graphical appeal. That is why you
should develop your presentation with the content
first, before deciding on the look
(colours, graphics, etc.) Create a good structure for
your presentation by reflecting on the goal of the
presentation, what your audience is thinking right
now, and what points you need to make in order to
move the audience from where they are to where
you want them to be. Write an outline on paper or
use sticky notes so you can move ideas around. By
creating an outline first, you ensure that the content
of your presentation is solid before you concern
yourself with the visual elements.
If you want your audience to be able to see what you have on the
slide, there needs to be a lot of contrast between the text colour
and the background colour. I suggest a dark background with light
text – I usually use a medium to dark blue background and white or
yellow letters. Some prefer a light background and dark
letters, which will also work well - which you choose will depend on
personal preference. Don’t think that just because the text looks fine
on your computer screen that it will look fine when projected. Most
projectors make colours duller than they appear on a screen, and
you should check how your colours look when projected to make
sure there is still enough contrast. To check that your colors have
enough contrast, use the Color Contrast Calculator.
   When deciding what font size to use in your
    presentation, make sure it is big enough so
    that the audience can read it. I usually find
    that any font size less than 24 point is too
    small to be reasonably read in most
    presentation situations. I would prefer to see
    most text at a 28 or 32 point size, with titles
    being 36 to 44 point size. The only reason I
    would use a font less than 24 point is when
    adding explanatory text to a graph or
    diagram, where you could use a 20 point
    font size.

Get your copy of "102 Tips to Communicate More Effectively Using
PowerPoint"

The review in The Globe and Mail, Canada’s leading national
newspaper, concluded that, “If presentations are part of your life, this book
is probably mandatory for you – it’s that rich.” It was the second most
popular business book on Amazon Canada and spent over three weeks on
their top 100 Business Books list. It has appeared twice in the Top 10
Bestselling Business Books weekly list in The Globe and Mail.
   This makes the presenter wait longer
    between each point and makes the
    audience members focus more on the
    movement than on what is being said. I
    suggest the use of the "Appear"
    effect, which just makes the text appear
    and is the easiest for the audience to
    read.
   During a presentation, it is very annoying
    to have the pointer (the little arrow)
    come on the screen while the presenter
    is speaking. It causes movement on the
    screen and draws the audience
    attention from the presenter to the
    screen. The pointer comes on when the
    mouse is moved during the presentation.
   To prevent this from happening, after the
    Slide Show view has started, press the
    Ctrl-H key combination. This prevents
    mouse movement from showing the
    pointer. If you need to bring the pointer
    on screen after this, press the A key.
   If the pointer does appear during your
    presentation, resist the urge to press the
    Escape key – if you do, it will stop the
    presentation and drop you back into the
    program. Press the A key or Ctrl-H to
    make the pointer disappear.
   Every two years I ask audiences what
    annoys them about bad PowerPoint
    presentations. The latest survey confirms
    that audiences are more fed up than ever
    with the overload of text on slides (see the
    latest survey results here). Instead of using
    slides that only contain text, use visuals such
    as graphs, diagrams, photos and media
    clips to engage the audience. I've
    developed a five-step method for creating
    persuasive visuals in my book The Visual
    Slide Revolution.
   Read the free chapter to see a summary
    of the process you can use to create
    your own persuasive visuals. Looking for
    professional photos that don't cost a lot?
    Check out istockphoto.com, where I go
    for great looking photos at reasonable
    prices.
   The last slide you speak to should not be the
    last slide in your presentation file. You should
    have three identical copies of your last
    speaking slide so that if you accidentally
    advance one too many times at the end of
    your presentation, your audience never
    knows because you don’t drop into the
    program, the slide looks like it has not
    changed. After these slides, you should
    include some slides that answer questions
    that you expect to be asked.
   These slides will be useful during Q&A
    sessions after the presentation. The final
    slide should be a blank slide so that if you
    go through all the other slides, you have
    a final backup from dropping into the
    program.


    Would you like to add video clips to your
    presentations? How about finding and using
    photographs that make an impact? Or creating
    graphs that clearly communicate numerical
    information? These topics and more are covered in
    my one hour webinars. If you can't attend the live
    sessions, you can purchase the recording and get all
    the same great information.
    Check out all the topics and the live webinar
    schedule at www.EffectivePresentationWebinars.com
   PowerPoint has a feature that allows you to
    be able to move quickly and seamlessly to
    any slide in your presentation. To do so, you
    need to know the slide numbers. The easiest
    way to print a list of the slide numbers and
    associated slide titles is to go to the Outline
    View and collapse the details for each slide
    (there is a button on the left side of the
    screen in this view that will do this).
   Then print the view. To jump to any
    slide, just enter the slide number on the
    keyboard and press the Enter key. This
    will move you directly to that slide. This
    technique is very useful for moving to a
    prepared Q&A slide or for skipping parts
    of your presentation if time becomes an
    issue.
   Sometimes we want the image on the
    screen to disappear so that the audience is
    focused solely on the presenter. There are
    two ways to do this. The first is if you want to
    blank the screen with a black image, similar
    to shutting the projector off (we used to do
    this all the time with overhead projectors by
    just shutting the projector off). Just press the
    B key on the keyboard and the image is
    replaced with a black image. Press the B
    key again and the image is restored. If you
    want to use a white image instead of a
    black image, press the W key each time.
Thanks for
 Watching!
GODBLESS:)
