How to set up the camera to work:

A - Putting the film inside the machine:

To place the film inside the machine, the film is taken out of its box in a dark room, then the cassette is removed and the reel inside it is taken out, then the end of the film is installed on it so that the sensitive side is inward, and the film winding becomes part of it on the reel, then the reel is installed inside the cassette and the film is completely wrapped inside the cassette by means of the film management screw located within the parts of the cassette, then we take the end of the film and fix it on the right spool so that its face is inward as well. Upon completion of this, the cassette and the spool will be installed at the same time until we hear a click, and thus the interlocking gear will have been engaged in the holes of the film.

Thus, the film is installed inside the machine. Note:

This must all be done in the dark.

2- How to open the lens:

In order to print the image on the raw film, you must set the image and then expose the raw film to a certain amount of light, so I made a hole on the camera called the lens aperture, and this hole penetrates through the light in a specific order, and the amount of light entering the hole depends on the weather condition, so the lens aperture varies in the morning when it is intense Light and when the light is medium or in the shade

There are gradations on the lens aperture:

B In the case when it is in room A - the scale is 3.5 x 4 at night and it has normal light.

B - 50 if we are in the staging ward 5 x 6 with 25 8 during the day but in a stable condition

- Scale 11 x 16 with 250 to depict a person running or moving. D - The scale is 11 x 16 with 500 to photograph moving but fast objects such as (the plane).

Time to use the scales:

- Or 4 in a room, and so on, or 6 in the ward, but

while stationary

B - 8 In an open land, but there is no sun, such as (tents). 11 - In an open land, but with normal sun. D - 16 m, intense as the mountains

From 1400 to 1600 capacity

Using the aperture lens at a steady state: A - 11 with 16 with 100 during normal and intense sun, but at steady state.

B - 8 with 100 in the case of shade (light but no sun)

comments :

The film should not be moved, except when it is necessary to take another picture

2- When moving the timekeeping screw, it does not complete a complete circle, as it is 1 starting with B from even from the second, so if we want to return it, it is 500, it returns in reverse movement.

3- When looking from the eye on the left, we find the image in front of us consisting of two images, so moving the coin until we clarify the two images makes them one image, and this is done by adjusting the edges of the image to each other and not by adjusting a part inside it.

Image time points:

The film must be exposed to light, as we talked about in the previous item, and this exposure takes place at a specific time and varies according to weather conditions. In intense light, the exposure time is less than in medium light, in shade, or in darkness.

How to take a picture with common cameras:

open the camera

b - Take off the object cover.

4- Take out the object, then move it to the left side to secure it. Adjust the gradation of light and depth to the appropriate light and depth e- Move the picture adjustment screw until it comes to the number (1) if the film is used for the first time or to the number of the next picture if there are pictures taken before and at the same time to set the left h to adjust the distance for the picture and correct it By managing K - by pressing the photo capture button, the photo will be taken.

mechanical movement of the machine

f - Move the time setting screw to the appropriate timing pulling it up

and move it to the appropriate timing

G - Look at the eye on the right to see the whole picture.

The coin below the object

E - Depth:

It is the distance between the first image of the object that has been photographed until the last clear image that appears in the image of the object, and the depth is set automatically when adjusting the distance.

6- Distance:

The distance to the object must be estimated so that the image appears clear and to adjust the distance

two ways

A - Estimating the distance with the naked eye and then linking it to the distance scale. B - Adjusting the distance automatically by (distance adjusting lever).

on the machine.

Machine care and maintenance:

1- Objects, in-kind and all parts of the machine must be kept in a place away from dust and sun and not to be subjected to injury or scratching.

Lenses should be cleaned with a soft brush and should not be touched with hands.

- If there are traces of fingers on the lenses, the lens should be cleaned with a piece of silk dampened with alcohol or ether, but not in large quantities so as not to cause decomposition or corrosion of the lenses.

- Objects should not be stored in a laboratory containing acids.

If there are traces of scratches in any part of the machine, it becomes -

Clean it with gasoline, then wipe it with Farlin

6- The camera should be stored in a cool, damp place.

9 - Objectivity should be tested every three months at most. 9 - The camera should be used gently and not rubbed against hard objects. Usage: Maintenance is carried out twice a week, and no maintenance is required

Maintenance after working with the camera daily

10- The sample should be tested at least every three months.

11- The camera should not be calibrated when no pictures are taken, because leaving the camera calibrated for a long time causes damage to the caliber

12- When turning the timing screw, it should not be turned from position B to a second, but it should be turned in the opposite way, because

The timing screw turns an incomplete circle

13- When placing the camera inside the leather bag, it must be ensured. Ensure that it is fixed inside it by means of the camera clamp located at the bottom of the bag
