    Default Digital Images to 35mm Slides?



    I need to give a presentation, non-professional, that involves a mixture of
    astro and non-astro images. My projection resources are limited, a 35mm slide
    projector or an overhead. I can print the color images to transparencies, but
    the projection tends to be washed out. I know people have photographed images
    off of monitors to make prints, but how about for 35mm slides? Any suggestions?
    In the mean time, I'll Googling; however, I suspect suggestions here might carry
    more weight.

    Had the same problem a short time ago.
    I photographed my "digital slides" from a PowerPoint presentation off my
    computer monitor's screen, using a slow shutter speed (~ 1/4s) so that the
    result wouldn't suffer from refresh problems.
    Biggest problem was stopping camera shake with my tripod on a carpeted
    floor. Worked OK, the results were sharp enough to see the line structure
    of my monitor's image.

    Years ago I used to be in the business of producing 35mm slides from
    files. There used to be a good many businesses out there producing
    them. Not so sure how many survive. The piece of equipment used is
    called a Digital film recorder. You might ask a camera shop who does
    this sort of work in your area.

    Regards,

    Have you tried some of your local photofinishing labs? There are half a
    dozen places around Colorado Springs that will take my digital files and
    convert them to slides. It runs around $2 per slide. Some use digital
    slide printers, and some print to paper and then do a copy slide.

    You might also consider borrowing or renting an LCD projector for your
    talk, since that is generally a better solution. Some Kinko's rent
    projectors.

    Here's more of my situation. I live in a fairly remote part of N. California in
    an area with 4-6K people. Most high-tech facilities are 40 miles and beyond
    towards Sacramento. One place in Sac wanted $150 per day to rent a projector!!
    Another place in Sac wanted $7.50 per image! I'm sure I can do better. Someone
    30 miles south of here told me he rented one for $50/day. I'd consider that, but
    I may have to drive 30 plus miles to pick it up. I guess there's something of a
    plus concerning the Sacramento rental angle. That's where I'm going to give the
    talk. I found a place called www.slides.com that does the work for $2.50
    image/slide. I think I'll just get out my trusty old 35mm SLR and give it a try
    from my monitor. I'm not terribly concerned about color and quality. If all else
    fails, I'll use foils. I suppose I could have everyone gather around my laptop. :-)

    Actually, a large TV might work. I've done that before with a 28-32" TV with
    pretty decent results. The audience might be in the neighborhood of 20-25 people.

    If you have enough time to buy something, you might look at flat panel
    overhead projector VGA displays.

    I think I paid about $40 for one including shipping on ebay a couple
    years back. It works great.

    Sounds interesting. How does it work? Do computer image appear on the flat panel
    and then are projected in the fashion of a typical overhead project? Seems like
    the result on a wall or screen might be fairly dim.

    You hook the panel up to the external monitor output jack on your
    laptop. The panel sits on top of an overhead projector as if it was a
    transparency.

    The images are a bit dim compared to a typical transparency, but it's
    quite useful, especially if you can dim the room lights.

    I've used one of these before. It's pretty useful for doing diagrams
    (or it was, way back when), but its utility for showing photographs--
    especially astrophotos--is very limited, in my opinion.

    I've had good luck with astrophotos on them - perhaps you had a dud, or
