Yes, in the sense that it current projector technology (within a reasonable price range) limits absolute resolution. No, when you consider that there are alot of factors that affect the quality of a slide show which are difficult to control. 1) You don't want to show your originals due to fading, and duplicates are just never as good. 2) Slides get dirty, so you're always chasing lint, dust, and the like. 3) It's very difficult to get perfect focus across the entire film plane, as film is never flat. 4) There is no opportunity to perform color corrections and other enhancements A digital slide show is totally repeatable. You can photoshop the images to your satisfaction, digital images never accumulate dust, and the LCD display being projected is always flat, so focus is never a problem. And, you can repurpose your slide show for deployment on CD-ROM, or on a website. Last year, at the Santa Fe Workshops, I saw a presentation by one of the instructors who specializes in landscape photography. His projector was a garden-variety Epson with 1024x768 resolution. His presentation slotted right in between others using conventional projectors, and yet everyone was amazed at the image quality. David Alan Harvey showed a video on that same projector (produced by one of his sons), of him photographing in Cuba. The video had a great soundtrack, with voice over by David, shots of him working, and loads of his stills. The effect was really great, even though it was just plain NTSC video. After more research, it looks like PowerPoint is going to work out for simple slide show. I spent the better part of this evening on some specific tests. The latest version has a 'background' audio feature, then you can overlay specific sounds that get played for particular slides. I'm trying to figure out if Final Cut Pro might do the job as well. The idea would be to basically create a High Def non-interlaced video. I think you could get quite good quality that way. - --Jim - ----- Original Message ----- From: "Dave Hillman" <dave@hillmanimages.com> To: <leica-users@mejac.palo-alto.ca.us>; "Jim Laurel" <jplaurel@nwlink.com> Sent: Friday, September 28, 2001 9:20 PM Subject: Re: [Leica] Slide show software > Jim, > > Aren't the advantages you have correctly described acheived at the expense of > image quality?
