Notes on Printing on Eastman's 
Bromide Paper. 
(By J. A. D. LLOYD, Assoc.M.Inst.C.E.) 
Thin delicate negatives full of detaQ are most suitable for 
printing on this paper ; in fact sueli a negative as might he 
considered too thin for alhumen paper, would he ahout right 
for gelatino bromide. The meta-bi-sulphite developer is 
eminently suitable for these negatives. It is made as 
follows : 
iPyro, 1 part, 
Meta-bi-sulphite of potash, | part, 
Water fill up to 10 parts. 
i Carbonate of potash, ] part, 
B. I Meta-bi-sulphite of potash, | part, 
( "Water fiU. up to 10 parts. 
Both solutions are 10 per cent., so that 10 minims may 
be said to contain one grain either of pyro or potash. For 
an Ilford ordinary plate each ounce of developer should 
contain 2 grains of pyro and 2 grains (to start with) of 
potash, the latter to be increased as required. No bromide is 
required, and no acid to preserve the pyro. Both solutions 
keep remarkably well. With this developer, and an exposure 
one-half longer than usual, a fine, delicate, negative, brim- 
ful of detail, can be secured. Such a negative looked at by 
transmitted light, reflected from a sheet of white paper (laid 
on the table), should show all gradations of density, and at 
the same time detail, even in the deepest shadows.
