Maco Genius Film
If you're going to give a film a name, go for the top. What
the name does not disclose though, is that this is a lith
type sheet film, and a good replacement for Kodalith
Ortho, which is now discontinued. It can be controlled in
contrast by choice of developer, using lith developers
such as the Champion Novolith, Fotospeed or Forte
products to achieve 'lith' contrast with total elimination of
half tones. Otherwise lower contrast can be produced
using print developers, or lower still in negative developers.
Genius is orthochromatic so can be developed by
inspection using a red safelight.

Ilford Ortho Copy Plus Film
Behaviour like FP4 without red-sensitisation. Relatively
high sensitivity for camera use, (40 ISO in tungsten, 80
ISO in daylight) and normal contrast. Available only in
sheet sizes. Useful where response to red is not
required, and development by inspection in red safelighting
is needed. If photographing to reproduce a 'vintage'
look it may be useful, as its response is closer to old blue
sensitive films than modern panchromatic materials.

Digital Transfer Film 165 micron
A Permajet product, clear inkjet film with an improved ink
receiving layer that handles considerably more ink than
other films. This yields high density large format negatives
that can be used to contact print onto normal printing
papers or be used in alternative processes. It is a
fast drying water resistant film with high clarity.

Coating Rods
The preferable alternative when using some sensitisers,
particularly platinum and palladium, where a substantial
amount of very expensive sensitiser can be left unrecoverable
in the brush. A syringe is used to lay a line of sensitiser
onto the paper, and the rod is then touched down
onto the paper at this point. It can then be drawn down
the paper, pulling with it the reservoir of liquid. The
amount of sensitiser should be calculated to be absorbed
after about 5 passes, and the result will be a carefully
metered application of sensitiser over the selected area.
However, the only choice over coating width is the width
of the rod, and for this reason several are offered..All are
made from thick gauge glass tubing, turned at the end to
provide handles.

Jiaban Brushes
These Chinese made goats hair brushes are ideal for
use with most alternative processes because a) they
contain no metal parts and b) are very inexpensive.
Especially suitable for applying liquid emulsions.
However in some cases, particularly platinum/palladium
processes, the use of a coating rod may be preferable,
as a brush retains a significant amount of the significantly
expensive sensitiser

Lotus Contact Frames

Not cheap, in fact outrageous, but then so is a Rolls
Royce. The Lotus frames are exceptionally well made,
on a par with the best wooden camera making, which
indeed is the other side of the Lotus business. We do not
keep these in stock, they are shipped out by the UK
importer, so if you are making it part of a larger order, the
frame will arrive packed separately.
The 20x24” model is made to special order, and takes
about 3 weeks.

Electronic Balances
For many years we supplied a traditional pan balance
with weights, but the manufacturer called it a day in the
end...less aesthetically pleasing, but easier to use and
more accurate, a choice of two electronic balances.
The Salter 3010 weighs from 1g to 2kg, and this is accurate
across the platen - some other relatively cheap
balances can vary quite widely depending on where the
load is placed.
A membrane covers the switches, and controls are
ON/ZERO, OFF, and a switch between KG/LB
The Salter1250 is designated an ‘Electronic Travel Diet
Scales’, and provides ultra fine 0.1g increments as
required by diabetics - this makes it equally useful as a
highly accurate chemical scales. Compact enough to
travel with, only 120 x 120 x 170mm, and the weighing
tray inverts as a cover for the platen. Uses a CR2032
lithium coin battery

Making Digital Negatives
PAPER for ALT. PROCESSES
'Making Digital Negatives' was first self-published by Dan
Burkholder in 1995, and was a very useful little 70 page
booklet aimed at introducing the photographer with an
interest in fine art into using digital techniques. The new
second edition weighs in at a mighty 350 pages, covering
a greatly extended range of topics. As we are importing
the book from Dan himself, we are able to offer the
book at the same price as the original edition, only £30.
This also includes a CD containing calibration tools, test
images, image layout templates, curves and colour table
settings, which you use as you follow the steps in the
book and run your own tests.

We do not profess to be paper merchants, but keep a
few specialised papers (at present down to one) suitable
for alternative processes. Arches Platine is natural white
and is particularly suited to iron-based processes such
as platinum.
