I am due to give a slide show to the local natural history society which is scheduled for about 2 hours duration. I have been in touch with a good friend who uses ACDsee, but unfortunately I have not got that programme. I am thinking of using Powerpoint and showing about 150 images.
Can any of you kind people advise as to if Powerpoint is OK and can I use TIFF files? I intend to prepare the show on my PC then transfer to my laptop which I will take with me.
All suggestions (polite ones ) gratefully received.
Best wishes
Phil

hi phillip,
how are you showing the slides? on an infocus or something like that? you might want to do a test run of the difference between tiff and jpeg, as the jpegs will allow the presentation to run a lot smoother. 150 tiffs if they are big in MB's might cause the show to crash mid way.
on a big display like an infocus you won't notice the difference between a jpeg or a tiff anyway imo. i recently had a slideshow run in a cinema as part of a weeklong conservation festival here in quito and imagine my horror when the format could only be made in 720 pixels maximum in jpg. fearing pixels the size of housebricks on the the big screen, we did a test run and such a small image comes up beautifully using cinema equipment.
anyway, do a series of tests on the show equipment, using the smallest permisible file size and i this will be the best way to go.
regards,
mark
PS, also your laptop screen is probably only about 96 dpi anyway to using 300 dpi tiffs wont notice anyway, so even if you're using your laptop, you can tone down the filse size accordingly.

Hi Philip
I also use Pictures2exe for creating slideshows. An excellent bit of software. You could also use Powerpoint though.
TIFF format is not necessary. Assuming you will show your images at full screen size then do the following ;
1. Resize to your monitor/projector resolution (e.g. 1024x768 or 1280x1024, etc)
2. Sharpen as you would for web images
3. Convert to sRGB colour space
4. Save as JPEG high quality (10 or higher)
2hrs - wow , that's some talk! Hope you've got a few balloons to burst to keep them all awake .
Oh, and another vote for PTE.

I agree with Nick, 2hrs is a helluva lecture. I would say most people's attention span is 1hr to 1hr 15mins, particularly with only 150 slides, you'll really be dragging it out. Better to leave 'em wanting more unless your brief is specifically for 2hrs (go for a break half way if so).
PTE is definately the better programme for delivering slideshows because of its ability to be easily configured for manual control. I also have ProShow Producer which is the pro version of proshow gold, but I still use PTE for all my lectures just because of the manul control. It just looks so slick when you use a simple fade and can scroll through at your own pace.
Another vote for PTE here, I certainly wouldn't entertain Powerpoint... for one thing absolutley zero awareness of colour profiles.
PTE is easy to use, with a polished result that displays very well, make sure you resize your images to JPG at the resolution (or slightly less) of the projector you will be using.

That will be fine for slideshows on a laptop.
