making the paper light sensitive;

Answer 1

Emulsion layer

Question 2

This refers to layer of photographic paper that is a gelatine layer containing barite crystals (barium oxide) to increase the reflectivity of the paper; the layer that makes the film glossy.

Answer 2

Baryta layer

Question 3

This refers to layer of photographic paper that is made of hard paper which must be chemically pure;
chemical content does not change or react with light or other chemicals during printing.

Answer 3

Base

Question 4

This refers to the combination of its texture and finish; texture maybe smooth fine grained, or rough and finish maybe glossy (semi – matt) and matt.

Answer 4

Surface

Question 5

This refers to coating that is made up by using a layer of paper which is coated both sides with a synthetic
polymer, usually polyethylene; forms the base on to which the emulsion is coated.

Answer 5

Resin coated paper

Question 6

This refers to coating that can be air–dried, needs large volumes of water for effective washing that can be reduced with washing aid.

Answer 6

Fiber based papers

Question 7

This refers to types based on emulsion with slow emulsion speed; for contact printing;

Answer 7

Silver chloride papers

Question 8

This refers to types based on emulsion with fast emulsion speed; for projection printing (enlarging);

Answer 8

Silver bromide paper

Question 9

This refers to types based on emulsion that the slow is used for contact and the fast is used for
enlargement/projection printing; they give an image tone from warm black to reddish brown, depending on
length of exposure, type, dilution and duration of developer.

Answer 9

Silver chlorobromide filters

Question 10

This refers to grades of printing papers for extreme contrast negatives

Answer 10

Question 11

This refers to grades of printing papers for high contrast negative.

Answer 11

Velox #1

Question 12

This refers to grades of printing papers for printing normal contrast negatives.

Answer 12

Velox #2

Question 13

This refers to grades of printing papers for negatives that have weak contrast.

Answer 13
