PPT Slide Show I've been asked to make a slide show presentation of some photos at a gathering and I was wondering what resolution I need for a big screen presentation. In other words, how much can I reduce the size of the photos and keep them looking good. Anyone have experience in this? Thanks!

Just sent you a link to a pdf I found on line -- let me know if you don't get it.

I posed this same question to my daughter who has some experience in the field. Like you, I had assumed that because the screen is big I'd have to use higher resolution images in order for them to look good on screen. Her opinion was that low resolution images are good enough. She said screen size does not really change display clarity. 72 ppi on a 22 inch monitor or 72 ppi on a 4 foot screen will look the same. I hope she is right because that is the size I have been planning for my presentation.

After I replied to this question I did an online search and found some very confusing answers. There were a couple of very good suggestions and a pdf table of various ppi sizes for different applications. But there were also many erreronous information pages. Several of the purported explanations talked only about dpi (dots per inch) which is a printer term, instead of ppi (pixels per inch). The site that made the most sense suggested making your pixel size match the screen size, usually about 1024 pixels for landscape image, for best output.

Hi Susan, I have done many projection shows using everything from large slides, scanned images and from laptop folders with varying types & sized images. Of course higher resolution does look better but even the small 400x600 jpegs look fine. The projector actually has more to do with how the images look than the image size/format. The big projectors used for concerts (4500+ lumens) have so much light that they will make everything look great :) I have (2) personal 1400 lumen projectors that are not as powerful but work for almost any situation I need them for (small clubs & venues).Theoretically you want resolution set at 1024 x 768 or whatever you are projecting at but as I mentioned, I have mixed matched all sorts and they still worked fine. I once painstakingly scanned 2000 slides that were once used for projection shows at Jimi Hendrix, Grateful Dead and other concerts in the late 60's and after spending even more time touching them up with Photoshop - the old original show made a triumphant return in San Francisco NYE 2003 :) Have fun - your show will look great, Carlton

Thanks everybody! I haven't got an answer back about the resolution of their equipment, but I think now that the 1024 x 768 will be okay. Or, as Ken Smith suggested to me, I might just set the large side at 1000 or 1024 and let Photoshop calculate the small side, since not all of the photos are the same dimensions.

I have found out that the screen size of the equipment is 1344x480 which seems pretty strangely wide. How is a vertically oriented pic sized to 1024 x 768 going to look with that--impossibly small? What other options would there be so that it would look okay? Sizing the long size as 1344? I'm totally in left field here, don't know what to expect.

Hi Susan, standard projector resolutions are: VGA (640 x 480) first two are almost obsolete, so you have three possible choices. If you really get this kind of projector, you could put two photos per one screen (side to side). Good luck, Bojan

Thanks for the info. I re-sized one vertical image two ways, one with the long side 1344 (leaving the software to do the other) and one with the long side sized to 1024 and sent it to them to try on their screen. They said that neither of them seemed to produce a "suitable" size on the screen--as Chinese tend to understate things, I assume that it really didn't look good. I feel that putting two image together on one screen would significantly affect the impact. Any other solutions that anyone can think of? Could they change their display ratios or something? If not, I may just tell them it won't be possible. This is really hard to believe--this is being held in a first class new facility with modern equipment--why would they have such strange projector resolutions?

Do you suppose they want each image to exactly "fill" the screen - ie to fit the dimensions of the physical screen? That just isn't possible if you have cropped to different ratios. Maybe the images are perfectly clear, there's just a lot of space in different places depending on the particular image and that is not pleasing to them. Can you arrange to see the ones you sent as they would be projected to determine exactly what they mean by "unsuitable"?

She meant that the size turned out to be too small on the screen, from what I understand. It's like the new BP gallery problem (at least on my monitor). To see the entire page, I have to change my screen resolution and then it makes the pictures look too small--which is one reason why I haven't switched over. Anyway, they don't know what to do and just emailed to suggest we cancel that part of the program, and I agreed. It also just so happens that I haven't been able to recover from an illness and may not even make it tonight at all! Guess it wasn't meant to be! Thanks for all your great suggestions!

HI Susan, I was looking forward to an update of how it went and read that you are ill so I wanted to wish you a quick & full recovery. I fight allergies all year long and some days, they get the best of me but I keep fighting and trying to eat/exercise to stay fit. I dont do pharmaceuticals but I do drink (drops) Eachinecea & Astragalus as E flushes your system and A helps rebuild your immune system. Blessings, Carlton

Thanks for the tips--I was touched! It was an infection in my nose caused by the cold and dry air which I was trying to cure with oil of oregano applied externally, but to no avail--finally went to the doctor! Anyway, I hope this discussion stays open in case someone does have some kind of solution--this gala happens every year and since it's a standard new government building, I risk running into it again. I would also love some insight into why they would have such weird dimensions. I think I'll ask their tech guy!
