I have finally finished scanning and cleaning up all my slides and have archived them as tifs.
Have started to experiment with slideshows and find that if I make them in 4x3 then I get a full but stretched image onscreen.
If I make them in 16x9 then the aspect is right, but have the dreaded black bits at the sides.
The solution would seem to be to to make in 4x3 but to compress the pics horizontally so that when played on 16x9 display will get a correct display.
Anyone know of a practical way of compressing the pics, as I have done this in the past for my daughters digital picture frame and it was very slow going, or indeed a better way of acheiving a correct aspect on 16x9.

Bob, I don't see how the AR can be right if you are finishing up with black at the sides? Can you outline your method please?
Proshow gold, pick 16x9 and get black bars or 4x3 and get stretching.
This is when played on Panasonic plasma which has good control over aspects.
If I make in 4x3 then I can choose 4x3 on the plasma, I get the same results as using 16x9. I think it has something to do with pixel shape ie square for 4x3 and oblong for 16x9.

Claire I can see why you couldn't understand.
I repeated the process and this time it came out right. I suspect I might have chosen 16x9 after importing the slides and this time I opened new show with 16x9. Very pleased with the ease of use of Proshow.

Ah! Glad you fixed it, I only ever use 16:9 projects so I guess that must be why I never experienced that problem.
Yes, Proshow is indeed very easy to use:)
Hi Bob,
I see you've solved your current problem but for future reference, the pixels are not square in either 4:3 or 16:9.
They are 1.067:1 and 1.422:1 respectively.
The key thing to remember for a true representation is to resize all your slides to 768x576 for 4:3 output or 1024x576 for 16:9 output. So depending on your source aspect ratio, you might have to do some cropping.
(If you want to be very picky, even that process is not exact because (SD) TV screens actually display 704 wide not 720 so you need to correct for this by multiplying the figures above by 720/704. It's normal therefore to use 788x576 and 1048x576 if you want your circles to remain true.)
Regards.
I went through all that when I was setting up my daughters digital picture frame, but Proshow seems to sort it all out for you . You just pick 16x9 or 4x3 and zoom into the part of the picture you want.
