[The following was recorded in a newspaper cutting pasted into the Minute Book 1886-1894, dated 25 April 1888]
Mr. W. Delanoy read a paper on “Development,” in which he described the different developers in ordinary use and explained their mode of action. Several negatives were developed before those present, and during the process attention was called to the peculiarities of each.
Mr. M.H. Stiles also gave illustrations of a method of producing satisfactory prints from non-exposed 1 negatives. This consisted in the employment of a print 2 as a mask – the dark portions of the print retarding the action of light and so preventing the shadows from becoming as deep as they would otherwise have been.
The example was shown of a print obtained with the mask and without it, the latter showing a very great improvement on the former.
[Notes – corrections were made in the minute book adjacent to the paper cutting as follows]
1. ‘non-exposed’ was to be preplaced with ‘under-exposed’, and
2. The following additional text was to be inserted after ‘print’ and before ‘as a mask’, which reads ‘from the same negative’
