road from which a photograph isimpossible. In order to secure certain details it was necessary that thenegative should be secured from a position at the south-westside of the churchyard, and the camera being set up at theedge of the hill at this side, it was found that the focus ofthe lens was too long to admit of the image being sharplydefined on the plate. To move backward was impossible, to take the photographin section undesirable, and the loan of a suitable lens out ofthe question, so an experiment had to be made. The imageof the tower was focussed as clearly as possible and arrangedwith the open shop, which produced a decided blurr. Thelens was then stopped down to F 64, and the accompanyingillustration (Figure i) shows the loss of very little definition.I have found this tip very useful in copying when a certainsize is required, and it is found impossible to quite reach thedimensions and obtain perfect definition. The stopping downwill give the desired crispness of detail. 270
