Taking a picture with a flash:

You should generally use a flash when taking a picture indoors. The range of the flash ranges between 28 cm and 6 meters. Install a flashbar unit in the socket and insert it firmly. After using all the five lamps on one side, turn the flash unit so that you can use five other lamps. When using the five lamps on the side facing the front, the camera will automatically stop working. To avoid losing the film, flash photos should not be taken in an atmosphere containing flammable gases or dust.

Four points to remember when using the flash:

-1

Focus carefully, as focus affects image exposure. 2 - Observe the background in order to get a balanced lighting in the image, place the body near a bright and bright background

3- Arrange the groups of people carefully, so all the people in the group should be at an approximately equal distance from the camera to ensure that they are illuminated by the flash equally. Avoid reflections - Do not point the camera directly at a mirror, a bright wall, a picture covered with glass, or any highly reflective surface, because this will reflect the flash light in the picture and spoil it. You can avoid this problem by standing aside and taking the picture from an angle

Photo in daylight:

The lens controls the exposure of the images taken automatically according to the lighting conditions that you see, and the sun must illuminate the body from the front or the side and not from the back. The electric eye gives the best exposure when the scene is more or less evenly lit—nearly the same in the background and on the object.

no

Note on the background:

If a large part of the image area has a brighter background or than the main object to be photographed, the electric eye tends to darken the exposure setting according to the background.

As a result, the object is either too light or too dark in the image. If you get closer to the subject, the effect of the background on the exposure is reduced.

Sharpness near and far in sunlight:

In bright sunlight, you can ensure the sharpness and clarity of everything in the image, whether it is a close object or a distant view. Do not focus on a near object or a distant view Scale the lens distance to the 5 meter mark and then in bright sunlight everything from 3 meters to the furthest distance will be sharp in focus Instead adjust the image
Using the flash in daylight:

The electronic monitoring circuit of this camera is designed to read both daylight and flash light and then combine them to produce a properly exposed and clear image. And to get the best results, the object should be away from the camera at a distance of between 1.2-4 meters, and in particular the distance from 2-25 meters, so that the results are wonderful.

The flash is useful in daylight in the following cases:

If the body is in shadow and the background is bright. The exposure is in danger of being too intense for the background or too simple for the object, and by using the flash you can get an attractive, sunny and bright image.

If the body is illuminated from the side by strong sunlight, the use of the flash reduces or prevents the occurrence of coarse and unpleasant shadows.

3 - A face that is lit only in a blue sky and not directly lit by the sun. It appears in the picture in a blue appearance, and the use of the flash gives a sense of the presence of sunlight.

4- In dim light and in the absence of a flash, the shutter remains open for a relatively long exposure period, which results in a blurred image. The use of a flash reduces exposure time and leads to
to a sharp image.
Photography :

Hold the camera close to your eyes, and after adjusting the focus, carefully hold the object to be photographed in the viewfinder. Hold the camera steady and gently press the shutter button , keep pressing until the image exits the exit slot and all camera noises stop

Slide the image holding it by its wide edge, it will show itself automatically: do not bend, compress or cut the image

Mistakes to avoid when holding the camera:

- Blocking the outlet slit with fingers: This can cause horizontal creases and lines in the image. If the image persists in the slit, open the film door in a dark place and rotate the film rollers to remove the film. Never attempt to remove the film when the film door is closed and forcibly eject the film.

From its exit slit, it may cause damage to the camera. Placing a finger in front of the flash unit (there is no lens) can reflect the flash into the lens, causing the image to become blurred and fogging.

Or the finger may block the flash completely, causing a dark or black image, and a finger placed in front of the electric eye can make the camera unable to set the exposure correctly.
Putting the fingers on the photo inflator: It may disrupt the movement of the device inside the camera, which makes the photos partially blurry, or makes the photos taken outside completely white, and the defect usually occurs in the next photo taken when the finger was on the inflator

. Brightening/Darkening Adjuster: For most images, let the Brightness adjuster | Dimming in normal mode. But if the main object to be photographed is too light or too dark in the photo, you can use the Brightness/Darkness adjuster to adjust the exposure for another photo in the same position and under the same lighting conditions. For a small change, rotate the adjuster by one mark towards lightening or darkening, and for a greater change, move it two or more marks. The setting automatically returns to normal each time the camera is turned off

Close-up photos: The SX-70 allows you to take close-up photos even from a distance of 27 cm, without using additional parts. From this distance, the camera shows the body at half its normal size. And you get the best results by using the flash. Always hold the camera steady. And in the dim light. If you do not use the flash, you must use a tripod or other stabilization device. The best way to get a sharp image when you are close to the subject is to first focus on the distance .
