What size images for slide shows?

[Autumn]

I have been making slide shows for a few years now. Initially, I used Slide Show to Go and still like this, but I can burn DVD's from Memories on TV, so tend to use this programme now.

I have never bothered resizing my images for the slide shows, I have just imported them as is. However, last night I was dragging and dropping images taken with my Fuji S9500 (9M) and it seemed quite sluggish.

I think I was once told that it was not necessary to have the image size bigger that the size of the monitor settings. I think this was the case if I was hoping to view it on the PC only, but if I am hoping to burn them to DVD to view on our 28" (and anyone else's, which may be larger) TV screen, what size image would I need, or doesn't it make any difference?


I have checked, and my original photos were taken with an

Oly Camedia 2M. 1600 x 1200 @ 72 dpi
Subsequently:
Canon Powershot G3 4M. 2272 x 1704 @ 180 dpi
Ditto RAW 2272 x 1704 @ 240 dpi
And Now
Fujifilm S9500 9M (but sometimes it is set to 5M) 3488 x 2616 @ 72 dpi

So you can see that on the face of it the Fuji produces the larger file. However, I am puzzled by the different dpi's and wonder how the Canon gets to have dpi's of 180 and 240 (I assume this because it is RAW). Also does this make it a larger file than the Fuji. I think it does.

Can anyone explain this to me please?

To recap, What size image do I need to resize to for burning DVD's and viewing them on TV. :confused:

The resizing suggested in the club world for projection in exhibition is 1024x 768, hope that will give you some idea.

Thanks Patrick. Well if it will successfully project on a screen, which is bigger than our TV, it will do for me. :)

Too many red herrings in your post Audrey :eek:

Forget the image resolution of your camera files, or the ppi they come off the camera etc. Even whether you show your slideshow on a PC or a TV whether its a small one or a big plasma. Its simply all too confusing :confused:

Think in terms of creating a file 1024x768 and you won't go far wrong. I recently had to produce a show for a large auditorium and the screen was pretty big. However the digital projector had a resolution of, guess what, 1024x768.

If you create a DVD show from your software then it simply renders the show you have created for that medium. Jobs a guddun :D

Resizing your images for the slideshow will also make things run faster on your PC as it seems you may have discovered can be a problem ;)

A well turned out digital image can project better than film; at the club we have now merged slide merit and digital files into one “projected images merit” and we had to go to great lengths to ensure slides didn’t look second best.

DPI (dots per inch) or, my preference - PPI ((image) pixels per inch), only refers to how your image would be sized when printed. The different dpi/ppi rates only show that different default settings were chosen for those cameras.

There are two ways of displaying a digital still on a TV display; one is by treating the display just like a computer screen, albeit a lower resolution and the other is, when making CD or DVD compatible slide shows, to create a movie that shows the images. With the former it's a bit of pot luck really, but luckily most TV displays will blur edges enough to avoid nasty sawtooth artefacts. With CD/DVD slide show applications, your image will be resized anyway, so you don't really need to worry about resizing.

Thanks Stephen. I appreciate your answer and I know I seemed to have a lot of questions, but things are clearer now. I will resize to 1028 x 768 as you and Patrick suggest.

I find that REALLY interesting Patrick as we had our first projected Digital Image Competition as a separate section, last month. I didn't feel that the images had the 'Punch' that the slides had and wouldn't have been at all happy if they had been merged.

Tomorrow, is our Second Open Competition, so I'll let you know if things have improved.

I would be interested to know to what lengths you went to be able to integrate the two sections and to what lengths you went to ensure slides didn't look second best. :) Did you have your projector calibrated?

Thanks, I didn't know it was to do with default settings.

Well I have very successfully made DVD's to be shown on TV, but I have never resized the original, but it seems, from all opinions, that if I stick to 1024 x 768, I wont go far wrong.

Thanks everyone for your interest and help.
