Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Colour-Blindness and Colour-Perception This book is essentially practical. The observations are based on the careful examination of 116 colour-blind persons and of all the recorded cases to which I could obtain access. I should be glad to hear from any colour blind person concerning his views on colour, and the difficulties which he has encountered. I have obtained much valuable information from colour-blind persons relating to facts concerning their colour-perception which they have found inconsistent with the ordinarily accepted views.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Theories of Color-Perception Objections to Young's Hypothesis on Physical ground8.-in the first place, the retina, in addition to its function as a receiving and transmitting organ, is made by this theory into a differentiating apparatus as well. This is rendered necessary because of Young's disbelief in the capacity of the retina to act as a receptacle for vibrations after the manner of simple bodies. There is something remarkable in a kind of hitch we some times find in the intellectual workings of even our greatest men. It has always been a wonder to scientists that Newton, with a mental power capable of originating so far-reaching a theory as the law of gravitation, should pass by the undulatory theory of Huygens as not capable of explain ing phenomena of light.'

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Physiology of Vision: With Special Reference to Colour Blindness This book is the result of numerous researches on vision and Colour-vision, the principal original papers of which are given at the end of the volume, and present the subject in a new aspect. It will be noticed that each section of the subject has been given from the point of view of new facts apart from any theory and so is available for an explanation on any theory. The subjects of vision and colour-vision have been Viewed too much from the point of View of theory and the primary assumption is made that the theory is true when this can be easily shown not to be the case, as for instance long papers on induction when there is no induction and the classification of colour blindness as red blindness, green blindness, etc., when this classification is so meaningless that a man may be classified by one observer as a case of complete red blindness and by another as a case of complete green blindness.

This book was released on 2016-10-19 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from An Introduction to the Study of Colour Vision HE vast literature on colour vision consists almost entirely of papers written in support of some particular theory. It is peculiarly difficult to obtain a general and unbiassed view of the subject. I have here endeavoured to separate the best established facts of colour vision from the theories, and have then discussed the chief theories in the light of these facts. I wish to express my great indebtedness to Sir William Abney, Professor W. Watson, and Dr Myers for their invaluable assistance in a very difficult task, which demands a not inconsiderable knowledge of such diverse subjects as physics, physiology, and psychology. The chief references to the literature have been given in footnotes. The frequent references to Abney are to his Researches in Colour Vision (london, and to V. Helmholtz to his Hand buch der physiologischen Optik. In the latter case each of the three editions contains material which is absent from the others, and the exact reference is given in the footnote.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Hunterian Lectures on Colour-Vision and Colour-Blindness: Delivered Before the Royal College of Surgeons of England on February 1st and 3rd, 1911 As there are many who are interested in the subject of vision and colour-blindness who are not acquainted with the structure of the eye, I will give a few details so that these persons may be able to consider the problem from the point of view of these lectures. The eye is very similar to a photographic camera, and an actual image is formed on the back of the eye just as it is on the plate of the photographic camera or on the view-finder. The eye possesses a lens and also an iris which acts as an adjustable stop and regulates the size of the pupil. The membrane at the back of the eye upon which the image is formed is called the retina. The retina has several layers, but the sensitive layer consists of two elements called, from their shape, rods and cones. The problem therefore which has to be considered is, how is the light which forms the image on the sensitive layer of the retina transformed into visual impulses?

This book was released on 2017-05-18 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Color-Names, Color-Blindness, and the Education of the Color-Sense in Our Schools Investigation of a railroad accident in Sweden, supposed to be due to color-blindness, led Dr. F. Holmgren, professor of physiology in the University of Upsala, to the belief that the defect must be ftc quent, and hence dangerous on both land and sea. Difficulty arose as to any certain method of detecting it quickly. The absence of any such method has been the especial reason why the defect has hitherto escaped observation. Using the theory of young-helmholtz, and applying a test suggested by Seebeck, he finally brought out his now well-known method with the colored worsteds. By this, and the imitations of it devised here and there, large numbers of persons have been examined all over the world, including both sexes, all colors, ages, and degrees of civilizations, etc. It is a curious fact, that till the expert could test quickly and accurately, the existence of color blindness to the extent now proved remained unknown. It is now admitted that four per cent. Of males are more or less color-blind, and in females not over one-fourth of one per cent. Are thus affected. My own tests, up to the time of writing this, are of males 801 were color-blind, whilst I found but 1 1 females among defect ive in their chromatic sense.

Book excerpt: Excerpt from Researches on Colour-Blindness: With a Supplement on the Danger Attending the Present System of Railway and Marine Coloured Signals I will also mention that the inquiry into the Re lation of the Colour of the Choroid to colour-vision, which occupies pages 88-104 of this volume, and par takes in great part of the character of an Excursus or Episode, is treated in several respects more fully in a paper read to the Royal Society of Edinburgh last April, and entitled On the Extent to which the Re ceived Theory of Vision requires us to regard the Eye as a Camera Obscura. It is printed in Trans. R. S. E., Vol. Xxi., Part n., p. 327. I have many parties to thank for assistance in pro secuting these researches. Professor Kelland most kindly aided me in the strictly optical portions of my inquiry. Mr William Swan rendered me a similar ser vice, and so did Dr Thomas Wright; and latterly I profited largely, as the Supplement and Appendix will sufficiently show, by the interchange of opinions with Mr James Clerk Maxwell.

Download or read book Photography in Colours Classic Reprint written by George Lindsay Johnson and published by . This book was released on 2015-07-21 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Photography in Colours The writer has not found it necessary, to make many alterations in this edition. In fact he has only corrected a few errors in the text, and rewritten page 91 ( 43) which answers the question "How the appearance of White is produced on a Colour plate." He regrets that he did not give sufficient credit to Professor Forster for his interesting discovery of the reason why white can be photographed as white on a colour plate, and he has, therefore, rewritten the paragraph relating to it. But if few alterations have been found necessary, he has been obliged to enlarge the book somewhat, owing to the progress which has been made since the last edition was written. A full description of the Raydex process has been added, as well as Gaumont's new method of Cinematography in Colours, and Carrara's method of reproducing Autochromes on paper. A chapter has been added on Art in Colour Photography, and also a further chapter on Photomicrography in Colour. The writer desires to express his sincere thanks to Mr. Walter Severn, A.R.C.Sc, F.C.S., for revising the latter. His great experience in this department of microphotography as Assistant Government Bacteriologist in Cape Town is a guarantee of its accuracy. He desires to add that the apparatus arranged for taking microphotographs by combining a vertical microscope with a horizontal camera is entirely Mr. Severn's own invention, as are the special methods of staining the slides.
