: Enter the film slideshows and making B&W slides (and color ones from
Negs)

good to hear the dream is still alive :-)



: So here are 2 Questions:
:
: 1. what kind of brands of camera mounted adapters should i choose?

I've seen the cheap all-in-one slide copiers but never used one.

the ones I've used were simply a translucent sheet of plastic or glass on a
adjustable rail which holds the film flat to the plastic.  A macro lens is
then used to focus on the film, a light source (either flash or blue
filtered tungsten light) is used to illuminate the slide - take a light
meter reading compensating for the density of the film then make your
exposure.

If you have access to a macro lens Kostas, you could always try to make a
setup to do the job using a tripod, a sheet of translucent acrylic and a
light.


regarding black and white, might I suggest another approach?  "Eastman Fine
Grain Positive Release Film"  can be bought in 100 foot rolls very
cheaply - it's an orthochromatic film that can be handled under red
safelight and can be processed in normal paper developer by inspection.
I've had a lot of success making slides from B&W negs in the following
way - Take a contact frame or sheet of glass, lay a cut of section of
EFGPRF down (emulsion side up) then lay your neg ontop of it, emulsion side
down.  Set your enlarger to some point (mark it off, you can repeat this
later) and open your lens up, make a 'test strip' exposure of say 2, 4, 8,
16 seconds and develop it, watching (and timing!) the development as you
go.

stop and fix as normal then gauge which is the best exposure time such that
you include the highlight details  and maybe modify your development for
the dark areas on the slide (your dmax)

you'll find you get pin sharp slides with a lot less fuss than by copying
the images :-)


hope this helps
