  • Ok call me slow if you will but.....

    I recently got hold of my dads old projector and now have a small itch to show some of my works using the projector and I was wondering how/if it is possible to convert a digital shot into a slide shot. In addition to the if and the how I would be interested to know the where as well - where (if the if is a yes) is it possible to get this service in the UK and now much can I expect to pay for it?

    Thanks for all the help :)


  • The 8000 is the version optimized for printing onto MF and LF film, as well. It's considerably more expensive, even on eBay, and was designed to be an alternative to the Rhino. The ProPalette 7000 is much cheaper and produces fine results.


  • I have no idea what the achievable resolution of the ProPalette 7000 is. I know that it is unlikely to be 4k. Alpha has used one, so he may be able to tell us.

    The majority of the work I did with it in the lab I worked in was making 35mm slides of digitally created art. The artists never seemed to have any complaints. Most of the time we were printing onto Ektachrome. Granted, if I wanted to have a digital image of mine printed onto a slide, I'd have it done larger than 35mm so probably on a Rhino LVT. I never experimented personally with printing my own digitized photos onto film, but the results I saw from other people's work were of acceptable quality for their intended purposes. Would I print an Ilfochrome? Probably not if I could help it. But for putting into a projector I think the results are adequate.


  • Personally for me you would get more bang for the buck. http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3728647&Sku=N124-2414

    More uses than just the one plus it will do what you want.


  • If SVGA (800 x 600 pixels, or half a megapixel) is all the resolution you want, and you are happy with a contrast ratio of only 1200:1 then that NEC will be OK. Meanwhile Alpha and I are debating whether a 4k, an 8k or a 16k film recorder (10, 40 and 160 megapixels, contrast ratio 6000:1) is good enough.

  • There's a table at the bottom of this page: http://www.ctcsouth.com/8000specs.htm Is that what you're talking about?


  • well you can also search ebay for "film recorder." So long as it's in working condition you'll be fine. But like I said, make sure it comes w/ software.


  • Why not just get a film camera, load in some slide film, and photograph your LCD monitor? I think the result it will be higher quality than most if not all "personal devices" will produce.

    Sync your shutter to the LCD refresh rate and play with the brightness/contrast for best results.


  • I found this place in an MSN search. And its in the UK.

  • Isn't the 8000 nothing more than a tiny 7 inch CRT with a film camera pointed at it? How would a 7 inch CRT produce better results than 20 or 30 inch LCD? We had 5 or 6 of these things in the staff work room at the university I taught at. They were left over from some past and forgotten era. Projectors took their place and no one used them any longer AFAIK. They're probably in the trash can by now.

    Displaying a hires framebuffer on a 7 inch CRT? I think a hood, a cheep-o film camera, and my LCDs would produce far far superior results. No?


  • :D

    I know most of the cheaper films I worked on scan at 4k. For example Jimmy Neutron and etc. Some of those were even upsampled from 2k plates. Higher budget films and ritzy TV commercials tend to use 8k. I personally haven't noticed many productions using higher resolutions than 8k - But I guess there are. But that's the motion picture industry too. Stills would be different I guess.


    You can acquire devices like that on a home budget though?

    Looks pricey to me.

    You picked the most expensive one. They start at $0.99


  • Though I have never used one, based on the results I've seen I wouldn't recommend the Digital Palette - I think that you will be disappointed with the resolution. The later ProPalette 8000 produces far better results.

  • I'll start by suggesting that it will take a better recorder than the ProPalette 8000 to make slides that would stand up against film originals. Back when I lived in the UK and had a little more room to move than I do in midtown Manhattan, I used a Leica Reprovit II to de-digitize my digitally-processed images. I printed a 12x18 inch print at 288, 360 or 720 ppi and photographed that, then used expansion ("push") development. This gave a maximum true resolution something like 5k to 6k (ie between 5000 and 6000 discernible points along the long dimension of a 24 x 36 mm frame). I considered that to be marginally acceptable, and I also considered the results to be an improvement over the ProPalette 8000.

    I can't see how photographing an LCD of the type in common use as a computer monitor gets even close to that resolution, unless you do some fancy multi-exposure thing with different sets of pixels, moving the LCD appropriately between the exposures. A single exposure of an LCD screen onto any decent slide film will show the screen pixels easily, unless some diffusion or defocus is used.

    Definity LCD film recorders use a 15 megapixel monochrome LCD screen with a holographic diffusing system - and being intended for 35 mm motion picture use, they do not usually write to the full size of a 24x36 film format.

    Remember that a CRT film recorder uses a monochrome tube and gives three exposures, each through a different separation filter. This means that the resolution can be higher than you could obtain from a colour CRT.

    I have no idea what the achievable resolution of the ProPalette 7000 is. I know that it is unlikely to be 4k. Alpha has used one, so he may be able to tell us.

  • Yes. It's called the Polaroid ProPalette/Digital Palette. It's of a breed called "film recorders." ProPalettes can be had on eBay for pennies, and I mean that quite literally. They'll print digital images onto film, generally slide. I've used them on numerous occasions. They run on software called "RasterPlus." Make sure you buy a Palette that comes with it, and a camera.

    To run it, once you get the machine setup (it's about the size of a printer), you load the film into the camera, mount the camera on the machine, import the image into RasterPlus, print, and then have the slides developed by a local lab.


  • I would repeat:

    More bang for the buck. More versatility. No carousels to mess with. Trust me, the fun of things like slide projectors gets old quickly. You can do the exact same thing, right down to the sound of slides changing, digitally a lot cheaper, faster and with better results.

  • hmm thanks for the suggestion Alpha - looks to be a better bet than paying out indeviduall for slides - £2 a shot is more than I am willing to pay for this. But it appears I am on the wrong side of the altantic for these machines - :(
    that or ebay hates me

    Sorry, wasn't meaning to recommend any particular model, just the concept.

    Points taken and a few things in there I didn't know. :thumbup: Thanks!
