I use a IFF system 100 copy stand light source, my EF180L lens, plus Kodak
ektchrome slide dup film type SP663 balanced for 3200K. This works for
copies from either my 35mm ,6x6 cm or 4x5" films.
The IFF copy stand unit uses the same column as my flat artwork copy stand,
however it contains a dichroic light source identical to that used in most
colour enlarger heads.
I simply mount my 1v or 3 on the column , place a slide with a holder mask
on the light table area (about 4x5 inch area) , set the proper colour
balance factors based on Kodak's numbers on side of film box, plus offset
for my light source, and expose per the light meter of the camera. I
generally add a 25mm extension tube to the lens to permit greater than 1:1
copies.
Given the large number of used colour enlargers I have seen at photo flee
markets lately, as people replace them with scanners and printers, you can
make your own by taking an enlarger head, mounting it upside down (provided
the filter unit allows this), on any copy stand. (or on it side if upside
down will not work)
The advantage of this system is that there is no real size limits other
than how far you can spread the light, using a good quality macro lens,
provides "grain" level copy of the original, and colour corrections can be
made on the fly. I paid $200 Can for the IFF unit at a Hamilton Camera
store (new unit, old stock). As to a macro lens, the Canon 180L
provides sharp images at almost any F number, my Tamron SP90 works best at
F8 to F11, based on trial shots at various settings and looking at the
copied slides with a 30 power microscope.
This system way out shines the various integrated slide copy units I have
tried, most of which are simple tubes with a cheap, small aperture lens
permanently mounted inside. While these work, and are simple to use, they
require you use a flash or other bright light source, and from my view,
never seem to resolve the grain of the original film, but then again you
get what you pay for.
