Velox is the very best paper for amateur use for it is simple to use, thoroughly dependable and is made in a variety of grades and surfaces to fit all sorts of amateur negatives.

It prints in any light, requires no dark room and permits the amateur to utilize his evening hours in print making. Its simplicity of manipulation and extreme gradation make it suitable for photographic work of every kind.

Velox is divided broadly into two kinds of paper called “Regular” and “Special” (hard and soft) each division containing a variety of surfaces. “Regular” papers develop quickly and are best suited for negatives lacking contrast. “Special” papers develop slowly, and give soft effects from hard negatives. Use “Special” Velox for negatives producing good results on “Printing Out” paper (such as Solio), and “Regular” only with very flat negatives (negatives lacking contrast).

Velox surfaces: In the “Regular” class are carbon (matte surface), Glossy, Glossy double weight, Velvet, and Velvet double weight. “Regular” Velvet Velox is semi-gloss and gives prints of exceptional beauty. This paper will give satisfactory results from very flat negatives.

In the “Special” class, the surfaces are Carbon (matte surface), Portrait (smooth matte), Portrait double weight, Rough, Glossy, Glossy double weight, Velvet, and Velvet double weight.

“Special” Velvet Velox has a greater range than any of the other “Special” papers.

Royal Velox is coated on a soft, mellow-tinted stock, which when re-developed affords all the soft delicacy of a rare old etching. It is made in two grades, “Regular” and “Special” and one surface, just rough enough to produce the desired effect.

Kodak Film Tank

Development, that former bugbear of the amateur photographer and especially of the beginner, is made a simple proposition by the Kodak Film Tank—fully as simple as any part of the photographic process.

The Kodak Film Tank automatically develops every roll of film put into it, just as well as that roll of film could be developed by the most experienced photographer. If directions are followed, if the chemicals are mixed and the temperature regulated according to instructions, a boy or girl can get just as good results from the Kodak Film Tank as an expert by any method.

In other words, every roll of film put into the film tank, where the simple directions are implicitly followed, will come out developed as well, or better, than that roll of film could be developed in the dark room by the most experienced photographer. And it is very simple, it eliminates the dark room entirely, developing the film in broad daylight, and is so compact as to be easily carried and used anywhere.

The Kodak Film Tank consists of a winding box, a light-proof apron, and a heavily nickeled brass solution cup with cover. In the Brownie Film Tank, however, no cover is necessary as the film roll itself is turned. All articles can be packed in the box, making the entire outfit self-contained.

The film to be developed is placed upon a reel in the winding box, the cover is placed on the box and the film is wound around an axis in combination with the apron, in such fashion that, when completely wound, the apron protects the film effectually from light, and may be removed from the winding box safely at any time. It is then lowered into the cup of developer, the cover attached and the film left to develop for twenty minutes. After development the film is removed for fixing.

Every step is performed in daylight and the exact time necessary for development, in combination with the chemical formula, has been scientifically worked out, so that all differences of exposure within reasonable bounds are taken care of. Especial attention is called to the new 2½-inch size, for the development of 1A or 2A films.

Kodak Lenses

The regular R. R. and meniscus lenses used on Kodak and Brownie Cameras have always been the best lenses of their respective types that could be secured. These lenses are perfectly adapted to everyday amateur photography, producing pictures under normal light conditions that leave nothing to be desired by the average amateur.

For those, however, who wish even greater efficiency and capabilities, we supply the anastigmat lens equipments.

The superiority of the anastigmat lens, without attempting to go into the technicalities of the subject, consists of—Perfect definition over the whole negative, absolute flatness of field, and higher speed.

In R. R. lenses the tendency to lack of definition toward the edges, which always occurs in an uncorrected lens, is so slight as to be unnoticeable except to the most expert eye. In a true anastigmat, it is entirely eliminated.

The speed of a lens is determined by the relative size of the diaphragm opening. An R. R. lens cannot be used at an opening greater than ⅛ its focal length, commonly designated asf. 8. But an anastigmat lens can be so corrected as to permit the use of larger diaphragm openings and still produce sharp, clear negatives. This larger opening admits more light within a given time than that of the R. R. lens, hence the anastigmat is much faster. Thus the Zeiss or Cooke Kodak Anastigmat lens, working at an aperture of f. 6.3 admits 60 per cent. more light in a given time than does the R. R.

This speed advantage enables the user to make short exposures on dull days or under poor light conditions, where hopelessly undertimed negatives would result with an R. R. lens. And under proper conditions, exposures up to 1/250 second with a Compound shutter and 1/1000 with a focal plane shutter, can be made with the anastigmat.

In the last few years there has been a steadily increasing interest in and demand for anastigmat lens equipments among amateur photographers, and we responded to this demand, first by furnishing the Special Kodaks fitted with Zeiss Kodak Anastigmat lens, f. 6.3—a lens fully corrected and offering the advantage of high speed.

These have been followed by the Six-Three Kodaks. These differ from the Specials in that they are simply our regular Kodak models, without the special covering and finish of “Specials,” and fitted with anastigmat lenses specially designed by Taylor, Taylor & Hobson, for Kodak use and called the Cooke Kodak Anastigmat. This lens works at f. 6.3 and is fully corrected in every particular.
