Photographic Negative e-bog

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. This book, like its companion, Photographic Printing Methods, is the outcome of my wish to testify to the exceed ing great interest which I take in' photography, an interest which has been deepened by my study of the literature of the science and a growing knowledge of the many processes to which it has given birth. Some few of those processes I endeavored to explain in my former volume. Others of equal interest I have selected for description in the following pages. I have aimed to select only those methods known to have a permanent value.
