    I am looking to move some digital files over to slide and I'm
    wondering whether or not uploading JPEG files for processing is a wise
    choice? I've shot the images as either uncompressed tiffs or NEF's.

    Also what approximate pixel resolution and aspect ratio should these
    images be reformatted as for output to slide? I'm hearing 1200x1800
    and a 2:3 aspect ratio.

    I don't want to get scammed when I do this online so if anyone knows
    of anyone solid and fast then please do pass on the info.

    35mm frames are at 3:2 ratio. The 'standard' image frame is 36 x 24mm,
    the slide carriers crop that just slightly.

    ("convention" is x:y, hence 3:2 not 2:3 ...comes to the same thing, of
    While I haven't seen any myself, a photoclub member who has had slides
    made from digital was very disappointed with the resolution of the
    projected slide (I don't know what the pixel dimensions were). I don't
    recall if he was satisfied with the color.

    There are several good slide makers I know I do good work,
    www.microlightphoto.com, also www.imagers.com and www.slides.com. It all
    depends on what film recorder the lab is using if they don't have Agfa,
    Lasergraphics or Management Graphics, don't bother.
    A 6.1 mp file set to a maximum jpeg (10-12 in Photoshop) directly from a tif
    (first generation) will give you a nice slide, don't resize, unless the company
    tells you to. Some filmrecorder software does a good job of resizing to
    4000x2700 pixels, some just gives the size you put in. I know the software I
    use does a very good job of resizing I've run tif files as small as 800K and
    gotten a useable image (at least the client was happy). The best images come
    from files over 12mb (not larger than 30mb). I do find the best images are
    directly from the camera (processed RAW) and the necessary color enhancement
    and light sharpening.
    Hope this helps.
