Image size and resolution
John Cassel
overhead projector. The projector resolution is 640 x 480. This
presentation will contain over 100 images and only a couple of pages with
one line of text each. The images are digital photographs that are about
1mg each. They are 16" x 22" x 72 dpi. To make the presentation as compact
as possible I want to resize the images to a standard resolution and at the
same time maintain the image quality. What size should I make the digital
photographs for my power point presentation?
Thank you,
John Cassel

You're pulling in two incompatible directions at once. "Compact" and "image
quality" are the opposite ends of the same ruler, more or less.
But here's the deal: since your projector does 640 x 480, then that's all
you're going to get on screen, no matter HOW high the resolution of the
images in your presentation. If you make the images higher rez, you'll be
able to accomplish two things:
1) Kill time while you watch PPT have to grunt and groan while it knocks
your images back down to 640x480
and
2) Lose image quality, since PPT will probably not do quite as good a job of
reducing the image as your image editing program can.
You want those images to be 640 x 480 pixels or at 72dpi, 8.888etc by
6.66666etc inches.

I size the image at 640x480x72dpi and then insert the image onto a slide the
image does not fill the entire slide requireing me to resize the image (drag
the corners to enlarge it). As PowerPoint stretches the image I would
imagine that the image quality suffers. I played in PhotoShop and discoverd
that the image size that seems to exactly fill the slide is about 975x731x72
dpi. THis saves me the step of resizing the image in PowerPoint as well as
puts as much of the image's data into the presentation as possible.
My question now is about the relationship of PowerPoint's slide and the size
of the image. What is the size of a PowerPoint slide? What factors if any
make this variable? If it is not variable then why is the size of images
for PowerPoint presentations such a mystery?
IE Why not have a standard answer to my original question? Something like,
"John, the optimum image size for a PowerPoint presentation is 975 x 731 @72
dpi."

Size tab in the Picture Format dialog. I can set the image size to 100%.
If I turn on the ruler I see that the standard PowerPoint slide is 10" x
7.5" no matter what the resolution of my monitor. So if I create bitmapped
images that are 10" x 7.5" @ 72 dpi then these images should just fit nicely
onto the PowerPoint slide (covering the background entirely). Is there any
mistery beyond this?
I've tried this ratio with my monitor set to several different resolutions
and it seems to hold steady. The PowerPoint slide is always 10" x 7.5".
Am I misssing something?
Now I want to know how I can set PowerPoint so that it always imports images
at 100%-no more, no less. I there a way that I can do this?
I'd also like to know how I set defaults like the slide style. I rarely
need anything other than a blank slide and it is a bother that anything else
would be the default.
Thank you,

The optimum size for an image in a presentation that's going to be
video-projected depends entirely on the resolution you'll set your computer
to, and that in turn depends on the max rez the video projector supports.
You're asking the equivalent of "What's the optimum number of gallons of gas
to put into my tank for my car trip tomorrow?" Unless you know where
you're going and how many mpg the car gets, you can't answer the question.

If you choose Blank Presentation instead of one of the templates when you
start a new presentation, blank is what you get. Or do you mean that you
want to force PPT to give you the blank AutoLayout instead of the
title+bullets one when you insert a new slide?
Which version of PPT are you using, btw?
Brian Reilly, MS MVP
You are correct about the PPT page size. A screen show is 10" x 7.5"
(actually it is really measured in Points at 720 x 540 (72 points per
inch).
You should be sizing your images to this dimension in Photoshop (or
equivalent).
Now the problem is that PPT will not always size images to 100%
depending on the image type. So I have a short VBA routine that sizes
the image to 100% of actual size and then positions it's top and left
to 0. Presto, perfect sizing every time irrelevant of whether it's an
Excel chart, table, picture, or whatever.

Yes, I want to force PPT to give me a blank AutoLayout when I insert a new
slide.
I am running PPT 2000 SR-1.

I do not know what you mean by a short VBA routine. WHat is VBA and how do
I do that?
Is there an image format that PPT will import at 100% size?
The presentation that I am putting together will contain over 100 slides.
Each slide will have one image. I would prefer to use an automated routine
in PhotoShop to format the images so that I can just drag and drop them onto
each slide with no further manipulation.
So far the only way that I have found that enables me to do this is to size
each image to 975 pixels x 731 pixels @72 dpi and save them as .jpg's. By
doing this the image just covers the blank slide but I see that the image is
being imported in PPT at less than 100%. IS there a workaround to get the
image automatically imported at 100%?
Thank you,

I am confused by your comment as I am trying the same PPT presentation on
different monitors at different settings and it would seem that once I have
made the slide the image size visually stays the same no matter what
monitor/setting or projector I show the presentation on.
Perhaps there is some subtlety that I am missing. Can you give me further
explaination on this?
What I want is a PPT presentation that will work on a variety of monitors
and projectors. I want to use images with the smallest file size that will
give me the highest image quality. In other words I do not want to be
putting images with a larger file size than is nesecary.
So far .jpg images that are 975 pixels x 731 pixels @ 72 dpi seem to be
working at all resolutions on all of the monitors that I am using. WHere
would the difference in monitor resolution come into play?
Thank you,

Nah, it was that Reilly guy what confused you. Trust me on this. I'm used
to him. <g>
I may have misunderstood what you were after. You described an image that
was alternating line of black/white pixels ... something that's quite
difficult to display properly unless you can force the app to display the
image at precisely one image pixel = one screen pixel or in some cases
integral multiples of 1:1.
As you change monitor rez, PPT will indeed maintain the image at the same
size on the monitor but it'll be mapped to different numbers of pixels, so
image qualtiy may suffer.

If we're talknig about everyday images instead of brutal test ones <g>, then
you'll want to decide the highest rez video setting you want to accommodate
and size the images for that, or perhaps slightly smaller. For 1024 x 768
max screens, the numbers you've come up with should work fairly well, though
matching to 1024 x would give slightly better quality.
Brian Reilly, MS MVP
Just to keep Steve happy (g), I'll try to confuse you more, but make
your life simpler.
If I were going to do what you are trying to do, I would classify my
images into two different categories,
"normal pictures like scans"
"abnormal pictures, specifically screen captures"
For normal pictures, I would only create one file to be used at all
resolutions, heck, you probably are only talking two resolutions here
and maybe a third.
For the abnormal pictures, I'd create one image for each resolution
captured at that resolution. For a reason to see why do a screen
capture of Windows Explorer with lots of files showing.
PPT will anti-alias and muck it up so you want to be as close to
perfect as possible right from the start.
For the normal pictures, I'd probably scan em at 1024 x 768 at 96 dpi
and they should all look just fine at any resolution.
But if you ever understand what Steve is talking about, you can feel
free to follow his advice (g).

put a check next to "Don't show this dialog box again", then click OK.
Now when you insert a new slide or press Ctrl+M you'll get a new Blank
Layout slide automatically.
When you've had about enough of that, choose Tools, Options; go to the View
tab; put a check next to "New slide dialog" and you're back where you came
from.

Sold! Excellent advice.
John Cassel
Thank you for all of your help. When I follow your directions I do get a
blank slide.
Since then I have discovered that pressing the 'enter' key also gives me a
new slide but those slides have title and text boxes. Is there any way to
get those slides to come on as blank?
Why do I get a new slide when I press 'enter'? I don't see it this listed
as a shortcut.
I know I'm asking a lot but it seems like the software was meant to be
pretty user friendly.
THanks,
John

What view are you in and where's the cursor (and what shape is it) when this
happens?
My guess is that you're in outline view; I don't think there's any way to
override PPT's behavior in this situation, but you could quickly enter a
bunch of slides in whatever layout PPT wants to give you, then select them
all and apply the blank layout to all of 'em at one time.

family party event. The projector I will use is cabale of 1024 x 768.
If my pictures are either at this resolution from a digital camera or
scanned at this resolution at 96dpi (as Brian suggested) should the
pictures look as good as they do on the laptop when projected? Does
powerpoint keep and project whatever resolution is brought into it?
I wanted to use mediastudio for this (and still may) but am limited to
720x480) Is that going to look more pixelated when projected than at
1024x768? I Anticipate about 6-8' screen
thanks,
Jack
Brian Reilly, MS MVP
Yup, it'll look better at 1024 since it is a higher resolution. Just
be sure your computer display is also set to match the projector's
resolution.
