The practice of photography : a manual for students and amateurs

Preface

have been so frequently solicited by my friends and pupils to supply them with brief instructions in the various Photographic Processes, that I have prepared tins little manual on a simpler plan than any other treatise I have met with, by endeavoring: to carry the student directly through the various stages of each > process, without distracting his attention by untimely degressions on the manufacture of chemicals or of apparatus— knowledge very useful in its place, but a stumblin-block when llll-timed. I have first described the Process on Paper, both fow Negatives and Positives; then proceeding to Glass I have gnven m detail every information connected with Collodion and A.lbumen and I think everything essential to the attainment of a . !g ood photograph will be found mentioned. Amid the immense yainety of formulae and methods recommended by different experimenters I have selected those which experience has assured me awe the best under all circumstances; but in an art of such won- Jw -l ™P ld P™S res . s we must expect great improvements daily: thiese shall find place in future editions, should they be called for One feature in this work, which I hope will be found useful is tine description of the various chemical substances used in photography: instead of being introduced in the space devoted to the details of manipulation, they are grouped together at the end: foir these, and for the general revision of the work, I am indebted
