SE1
EMULSION
SE1 Emulsion is made for us by one of the main photographic manufacturers in this country, this is a normal contrast bromide emulsion which is versatile and easy to use. Contrast: reasonably hard grade 2.
The high silver content allows a certain degree of dilution with water in many cases. If applying to a transparent medium use full strength, but on opaque surfaces such as paper do tests using 1 + 1 and 1 + 2 dilutions with water.
SE1's substantial concentration of high bloom gelatin yields good adhesion to many surfaces, often without subbing beforehand.
Processing is as for normal paper- the emulsion is quite robust, and does not usually need hardening, or the use of slow fixing agents. The image colour is neutral to slightly warm-black, and it reacts well to toners of all types including selenium, also to Lith. development. A separate subbing solution is available for optional use when coating smooth surfaces such as glass.
