I use http://www.peak-imaging.com/htmls/film_processing.htm for my processing ;
and they charge £4.80 for a 120 roll. There is a postage charge on top so more
than one roll gives better value.
I have a pair of Rolleivision 66AV projectors which I 'reluctantly' had to buy
complete with a Rollei fade controller at the end of the day at London
Photographica a few years ago from a 'tired, must sell at what ever price, I do
not want to have to carry this lot home' vendor. I then had the task of
carrying it home and soon saw why he wanted to off load it.
Not only can the setup do a fade show, it can do side by side panoramas and 3D
projection. I have a Rolleidoscop 6x13 which I enjoy using but the reported
discontinuation of slide film may soon make that a dinosaur but in the
meantime, I take it out for a 'walkies' every so often.
Polarising filters and polarised glasses - they need to be linear ones - are
required. Coloured filters with coloured glasses can be used but that destroys
the colour rendition of quality transparency images. I made a metalised screen
using Screen Goo (Goo Systems Ultra Silver 3D Pair) from
http://www.goosystems.co.uk/products.php.
This is an American product but the UK/European supplier is 2 miles away from
me so a visit was worth while. A metalised screen retains the polarisation of
the images on reflection whereas a conventional screen diffuses the light
reflected from the screen.
It is imperative that the slides are positioned accurately in the mounts -
vertical position and horizontal angle of the image together with the
horizontal offset have to be carefully adjusted. Because they are seperately
mounted, I used a guide downloaded from Rocky Mountain Memories
http://www.rmm3d.com/
It is easier to mount pairs in a single mount for viewing with a stereo viewer
because both slides can be viewed side by side with the correct linear
displacement at the same time through the viewer and correctly positioned
before being taped in place and the mount sealed. The individual 6x6 projector
slide mounts do not permit a viewer to be used because of the greater linear
displacement caused by the frame width of the two mounts, hence a guide is
required to position specific features of the image and create the correct
linear displacement for projecting. When projecting a number of images, correct
alignment of each pair is essential otherwise members of the audience have to
continually adjust their visual perspective for each image.
Setting up and aligning the projectors for stereo projection is quite a time
consuming process. Aligning the two images from the projectors, one on top of
the other requires patience. The effect of keystoning can be reduced by angling
both projectors to the screen, one upwards and one downwards. Rollei made an
extension leg to support the upper projector which should be adjusted to align
the images in the horizontal plane and turning one or the other adjusts the
vertical plane. I made my own extension leg because the only one I could find
was on Ebay and the German vendor wanted too much for it. Slight adjustment to
yaw - if that is the correct term - can be made with bits of paper or thin
card. The lamp brigntness must be matched too. This is more easily assessed
once the polarised filters have been attached to the lens and rotated to be 90
degrees to each other. Viewing through the polarised glasses enables the
filters to be rotated correctly when opening and closing one eye at a time also
the relative brightness and final minor adjustments to projector angles can be
made.
Mounting slides takes about 20 minutes for each pair, projector setup takes
about 3/4 hour, take down, 10 minutes!
Impressive slide show, well worth the effort for an enthusiastic audience but
not really worth it for a bored audience viewing the annual holiday snaps.
Panoramas will be my next challenge, that is on my bucket list.

But for the most part, I wait until summer visits to Europe, and head to
a DM drugstore in Germany, for the 2.40 or 3.40 Euro processing charge
for a roll of 120, price dependent on whether sleeve or unsleeved.
Which other countries have similar prices to develop 120 slide film John
