Slides From Digital Images


#1

This post is in response to Cynthia Wiigs question; has any one had
experience turning digital images into slides? Yes I have done it
with very good results. If your camera has an image resolution setting
that is capable of producing an uncompressed TIFF file you can produce
slide quality images. The Nikon Coolpix 950 has this capability. I
shot an uncompressed TIFF image and then had a slide made from it. I
set up the projector and screen and looked at traditional 35mm slides
and the slide made from the uncompressed TIFF, both enlarged images
looked exactly the same.

Now, do I make all of my slides from digital images? No. The
uncompressed TIFF files take up enormous amounts of memory. The cost
for processing is $8.00 a pop. It is nice to know that I can get
slides from using the digital camera but most of the time I set up the
jewelry in the photo booth, first I shoot the piece with a 35mm camera
and then the digital camera. If your camera can shoot slide quality
images that means that you can e-mail slides quality images. The photo
booth that I have set up is based on the Charles-Lewton Brain design.
Please check out his photo on this forum. His book and
video on the subject are fantastic. Thank you Charles.

My web site has examples of jewelry shot with the Nikon Coolpix 950.

Best wishes to you Cynthia.

I get very good results from scanning in a 5" x 7" print and after
editing, and maybe adding a title, or even bringing in other images
to make up a combination, I send a bunch of JPEGs to Elegant Graphics
by ftp (much quicker than email attachments) and the resultant slides
are super. They ask $4 for a pop for JPEGs. Seems it’s now $5.

By very good results I mean when projected at a 600-seat conference
centre the blown-up image starts to have some slight pixelation, esp
seen in the text. In a normal darkened room situation they are fine.

It’s important to treat the JPEG file format with respect. Only use
it for a copy of the final file if you have to upload it somewhere.
For storing and editing I use TIFF format or the native image file
format of my conputer ‘sprite’.

Regarding keeping sharpness of image in the 35mm slide I reasoned it
out this way. For a reasonable printout held right in front of you the
image ought to be at least 300dpi resolution, so I worked out what
distance the slide will be used and aimed for a scanning resolution
which produced a 24mm x 36mm image at 1200 dpi, so when the slide is
projected it will be on the screen at close to the 300 dpi.
