35mm slides are still great for presentations to a large audience. Does any one know of an inexpensive way to convert digital images to slides?

Converting digital images to 35mmm slides

This issue was discussed recently in the Olympus SLR forum where it was demonstrated that it is possible to produce very good quality 35mm slides from Olympus E-10 images. I understand that this service is available at most of the larger photo-processing shops etc., although I have no experience of it myself.
For more information see the following threads:

Hope this helps.

The referenced threads certainly show the feasibility of quality digital to slide conversion, but the cost, at $6/slide and up, is much too expensive for my needs. I wonder what photography clubs are doing in the way of presenting their member's photos? I'll do some followup on this and post results.

Set an SLR loaded with 35mm slide film on a tripod, open digital images on your PC, monitor display at full screen, set SLR to manual focus, zoom in, take shots off your monitor display. Bring the films to Target/Walmart/Sav-on for developing. $12 for everything.

This method may be acceptable if quality isn't a significant consideration and you have a high res monitor. A film recorder would produce a much higher quality result, but at a price.
Some issues trying to shoot from your monitor:
The color temperature will need to match the film sensitivity or the images will all have an odd color cast. If your monitor doesn't have color temperature controls, you may find it very difficult to get acceptable color.
Use a slow enough shutter speed to avoid catching a black band of as the monitor is refreshed.
You should find the correct exposure to use in manual mode and not allow the camera to autoexpose each image. You may try starting out by metering an 18% grey image on the monitor.
Be sure to get the film plane parallel to the monitor to avoid keystoning and depth of field problems.

I'm scheduled to present a 'slide' show to our local camera club on Oct. 23. I'll be using a laptop and a digital projector. It will be a first time for me so I have some reservations about the resulting image quality but here's hoping.

This is a subject dear to my own heart as I am an active competitive member of a camera club and need to show slides. I started in digital in 1993, and for the past 3 years have been almost entirely digital.
I tried the service bureau route. This worked very well (here in the UK) up to a few years ago, when service bureaus were generating lots of slides for presentation work, but my feeling is that as the volume has gone down a lot because of increased use of electronic projectiors, so has the quality fallen. The pirce however remains as high as ever!
I now take screen shots off my monitor and it works well. I use the highest resolution possible on the monitor - in my case 1200 x 1024 - compatible with the full colour range, and run the slides through using thunmbs plus screen show, with the gamma reduced to 1.2 or 1.4. It is essential to reduce contrast on the monitor. many of you will have more modern monitors that may give 1600 x 1200 resolution.
My big problem was getting correct colour balance as pictures were much too blue. At first I tried trial and error- you know, set the monitor colour controls, take a few pics, send the film away for processing, wait a few days, then try again!!!!
I suddenly had inspiration. I put a black and white picture on the screen, got out my digicam, set its white balance to daylight (not the normal automatic), put ii in preview mode, and simply adjusted the monitor controls until the picture looked OK on the camera lcd screen. It worked like a charm.
One other thing was avoiding distortion. My Canon zoom lens (28-105mm) has severe pincushion/barrel distortion depending on the focal length chosen, but somewhere in between you should find a neutral point. I found this by putting up a simple rectangle on the monitot and then closely observing this as I moved the camera backwards and forwards, always filling the screen of course.
Of course overall results are not as good as a good film recorder, and you certainly would not want to try and make prints from these slides, but overall, on the projection screen they look pretty good- and they are cheap.

In San Diego, I copy them to a Zip disk and take them to a place called Chrome
that does a lot of photo processing, printing and digital work.
Everything is fine except the cost is about $5.00 per slide, not exactly inexpensive,
so you just have your best images converted.

That's a very creative solution. The methond could create a real problem trying to get back to a calibrated monitor settings with some monitors. It would be wise to mark the position of analog color controls if possible and note the correct settings (and successful tweaks for slide copying) from monitor set-up displays as you try this...

So it seems that it is cheaper to just shoot slides in the first place until a cheaper power point/laptop, or whatever comes along. To own your own digital projector is pretty expensive.

Just to get back regarding the digital 'slide' show. Apart from a bit of finger trouble with a lap top with which I was unfamiliar, I was very happy with the quality of the projected images using a Panasonic digital projector (don't have the model number), an up to date lap top computer and Irfanview to display the images. In this case the digital projector was loaned for two back-to-back presentations to the local camera club. Now if those things were available at a lower price the problem would be solved.
