(See Illustra-tion No. 50.) 692. Final Cautions.—Remember, for the best resultsit is necessary that the material used in making the pin-holeshould be very thin and absolutely opaque. The hole mustbe perfectly smooth and round. Give enough exposure. Ifsix minutes are required, no harm will be done if you giveseven, as you will be giving only 1-6 more time. The size ofthe pin-hole depends greatly upon the distance the pin-holeis from the plate; the shorter this distance the smaller maybe the hole. The greater the distance with the same sizehole, the more exposure will be required. When makingprints from pin-hole negatives, do not use a glossy or toosmooth a paper; the greater the diffusion the rougher shouldbe the paper. Make proof prints from all negatives and filein your proof file for future reference.
