What size do backgrounds need to be when making them in Photoshop?
Bill Dilworth - 24 Oct 2007 20:12 GMT
PowerPoint will use what you give it and stretch or shirk them to fit the
number of pixels required.

Now, here is where it gets a bit tricky.  PowerPoint can be set to run at a
specified screen size (resolution) or can be set to run on the users native
resolution.  However the native resolution of the users screen can be
different from the user's projector.  Users may have jumbo-tron monitor's
that will look very pixilated when seen from close up.  Others might be
using PDA's to view the same presentation.  You will never be perfectly
right for all possible situations.  Large pictures = large files.  Balance
picture image quality with file size.

Bottom line, most screen and projectors can display 1024 x 768 fairly well.
I'd make it that size and let PowerPoint deal with it from there.

Ok.  Good info.  But what happens when you print.  I am doing a presentation
and we print full slides on 99% of all our presentations.  PPT is stretching
the backgrounds I make in Photoshop.  The size I was making them is 10 x 7.73
at 150 DPI.  However, the background is doing what you said, being stretched.
I was wondering what the native size was for printing.  PPT 2007 also wants
to automotically adjust based on the information on the slide.  On the
background I am currently using it is ashusting by -3% up and down.  I am
acustomed to making Photoshop files to fit the info on the PPT slide.  Now
the resolution on printing is pixelated.

If you are concerned about printing quality, you will want to design the
Photoshop images for 10"x7.5" at 300 DPI or 3000 x 2250 pixels.  Then have
PowerPoint print the slides actual size by unchecking the "Scale to fit"
option in the print dialog.  Also make sure that no one "optimizes" the
pictures in the presentation for screen size.

This should improve the quality of the printouts, but will make the file
sizes a bit larger.

300 dpi will be over the top unless the resolution of the printer is insanely
high (we're talking typesetter).  

200 is generally plenty.

But you mentioned compression, Mercer mentioned 2007 and do we have a bingo?
PowerPoint 2007's automatic compression mis-feature causing reasonably sized
graphics to get downsampled?

Ah, good.  But you've heard back that it didn't help?

Yes.

Look at the thread from October 23: background fuzzy from Photoshop

Thanks.  Well ... sorta heard back.  See Kathy's followup question in that  
same thread.  Good question.  It's not clear whether the photo got  
re-inserted AFTER making the registry change.
