1 - The pages of the magazine are the property of the readers, and we have repeatedly announced this, provided that the pictures are important for publication. You have the right to send other works as long as they are renewable and worthy of publication, either within the section “The Amateur Club” or “Camera Talk”, or any other section that is appropriate to the quality of the images.
2- It is difficult to give a correct answer about the largest company, as each company has its own specialization. As for the largest and most important company, it is Linhoff, and its production is limited to professionals due to its large structure, and therefore
For those who are able to pay for it, as it is considered one of the most expensive cameras in the world, followed by the smaller structure of Hasselblad, then Leica cameras of 35 mm sizes, which are considered the most expensive and important of Japanese cameras.

As for Canon and Nikon, they are the first in the manufacture of Japanese 35 mm reflex cameras.
3- Chrome films, which are of two types - Ectachrome and «Codachrome», they are slide films, or positive - slides -
It is characterized by the accuracy of its colors and is used in the media, books and magazines, in addition to displays on wall screens in homes.
Schools and universities, which are very expensive due to their accuracy. In comparison, buying a normal color film and developing it is almost equal to the price of chrome film⏹

⏺Filter Effects in Handbook

The first question: I learned through one of the publications of the art of photography that there is a booklet called (COKIN) and another called (HOYA) through which the results of the filters can be studied. Please advise me of the way in which I can obtain one of these two booklets, and from where, and can the art of photography provide me with a copy of one of them. Please indicate the language in which the booklet is spoken.

- The second question: I also knew that there are cameras that capture the third dimension.. What are these machines? Do you need special films and can they be printed on photographic paper?
I also hope that people will conduct a special research in the future on this
New style and art.

1 - Indeed, there are brochures for the effects of filters, and they are available in both English and French in Beirut stores. We apologize for sending any photographic materials at the responsibility of the magazine.

2- The third dimension camera is called (NIMSLO), and it is a regular 35 mm camera that uses 35 mm films. It is known that the available cameras show the image from two sides, length and width, and this camera allows recording the third view, i.e. depth, and it is also available in the market.

The problem, however, is in the development of the photos. You have to send the films to America to have them removed, as there are no laboratories for them in the Middle East yet. And we had provided sufficient information about this camera in Issue No. 12, you can return to it.

⏺ SUNPAK flash photography

I would like to provide information about the (Snupak SR 30) flash, which is an automatic recoil flash that I owned, but I did not get a satisfactory result with it.
I have attached two pictures with the letter, and I ask you why they appear in these faded colors.

Faisal Abu Quoud

It is clear from the attached photos that it came without its need of sufficient light. Here, you have to follow the information behind the flash to get a sufficient amount of light for the subject. Do not photograph unless the flash is ready, that is, when a red indicator flashes indicating readiness.
When you use the flash from other than the location of the camera, you must use a wide aperture lens - f / 4 - or
It decreases according to the distance as well, and you have to pay attention to setting the sensitivity of the film you are using, i.e. Aza-V
The location of the flash and therefore this will help you to get a location P to ensure a full charge of light ⏹

⏺ Lenses and flash photography

1- It is noted that there is a crosshair in the hands of cameras and lenses of a number of companies that produce them. Is there a scientific basis for this crosshair?
Or just a trade agreement?
For example: What are the companies whose lenses are compatible with the camera? (RICOH XR-S).

2- Some of the photos taken with special effects - overexposed or night photos - come from laboratories with faded colours. Is this a personal mistake on the part of the photographer or is it due to electronic calibration in modern laboratories? And what is the way to avoid this result?

While shooting close-up with the flash, some dilemmas appear
A - Calculating the lens aperture after adding close-up lenses.
- Two lenses sometimes 3 + 2 + -
B - The camera's silhouette appears on the subject, especially with close proximity.
C - The section of the subject facing the flash appears brighter.

Dr . Rabie Othman

1- Each type of camera has its own lenses, which means that any lens, in principle, cannot be attached to any other camera.
This is what makes their prices rise steadily. From here, some companies specializing in the manufacture of lenses have offered lenses of all sizes and types, so that they can be installed on any camera, either with a fixed ring, or with an adapter - a mounting link - and as a result of the offer, the prices of these lenses were Less expensive than the brands of camera companies.
It is a lens that accepts installation on a Ricoh camera. You can choose: (SIGMA) and (SOLIGOR)

2- It is difficult to judge if the reason behind the dull color is. It is the photographer or the tester unless we have models of the result you are talking about.
Note that the laboratories work according to amateur systems, which clarifies the matter, and here you have to make sure that the exposure is on the film, so if it is correct and clear, you can request a manually enlarged copy, and of course its cost will be more. The other solution is to adopt slide films -
Slide - Here you will get a satisfactory result, if the exposure is correct, or you have black and white
Which enables you to obtain the required gradations.

3 - With close-up photography and with flash, you have to adopt the largest existing lens aperture number - i.e. f / 16 or f / 22 - which reduces the charge of light and prevents the brightness you are talking about.
Or you have to use a light diffuser when shooting close-up, which is a filter for the flash or relying on indirect light, so that the flash light is aimed at the ceiling with a wide aperture of f / 2.8, depending on the distance between the flash and the ceiling, so if it is close, it depends. F / 4 .

The emergence of fantasy, a given with artificial lighting if you adopt close-up photography preferably adopt a dark background, otherwise you have to adopt indirect light ⏹
