What is the color of the electronic flash?

The color temperature of the electronic flash is somewhat similar to the temperature of daylight, and the first flash guns gave a very cool blue effect with color films. Most modern electronic flashguns now contain a gold-coloured flashlight, or the lamp is mounted behind a pale yellow screen to soften the light temperature for a more pleasing effect. The color temperature of the light has no effect on black-and-white films. How is the exposure time calculated when more than one flash gun is used?

This topic relates to the question of whether flash guns are aimed at
From the same part of the subject to be photographed, or if each of them is used to illuminate a separate area. In the event that one flash gun is used as the main light source, and the other flash guns are directed at the ground or background, hair, etc., the exposure depends only on the main light and the emitted lighting. Other sources are neglected. In the event that all guns are directed at the same part of the subject being photographed, they must all be taken into consideration. If it has the same capacity and distance, the index number of one group must be multiplied by the square root of the number of units or groups. For example, for two units, the pilot number is multiplied by the square root of 2 - 1,4. Assuming that the pilot number is 115, the result will be a practical number equal to 160. With three units, the result will be 115 x 1.7 = 200

it is done. If the pistols have different yields or are at different distances, then all their index numbers are then divided by the total output by the square root of the number of units. The result gives us the practical guide number. Alternatively, each guide number is divided by the practical distance, the resulting lens apertures are added together, and the resulting total is divided by the square root of the number of units.

How is exposure time calculated when using flash or synchronous sunlight-based methods?

This is related to how and when to use the flash. If the sun is the main light source from the front or from one side, then the flash light can be neglected. If the sun is located behind the subject to be photographed and the flash is the main light source, then the lens aperture or the distance from the flash to the object The photographer changes and varies according to the different intensity of the flash effect ideally it should
The object to be photographed does not appear to be illuminated by a flash but must be illuminated by reflected daylight. To do this a meter reading is taken and the flash is moved to the distance from the subject which is found by dividing the pilot number by the working lens aperture. At this distance, the effect of the flash will be almost equal to that of the sun, but it will look a little unnatural. It is better to increase the distance from the flash to the photographed object by half again, or to place a clean tissue over the top of the flash to reduce its effect a little.

Can a flash gun designated for one model of camera be used on another model of camera?

Most dedicated flashguns designed for automatic flash exposures on a particular camera make or model will normally fire when attached to another camera model as long as they all have the same mount attached to them. It is very rare for it to do anything other than properly synchronize with the P as long as the additional contacts on the accessory base vary in number, shape, size, position, shutter opening.

In the appropriate camera, the contacts are often associated with the shutter, so it is automatically set to a certain speed when the flash is turned on while it is fully charged. In some cameras, the flash programs the exposure regime or responds to a sensor in the camera. On other cameras these control features are not linked or coupled together and the flash gun must be used as a fully disconnected unit

A few dedicated flash guns have a sync cable with a standard 3mm coaxial extension pin attached to it and there are only about
Half of the cameras designed for dedicated flash guns have standard 3mm coaxial sockets. Why do we see on some photos taken using flash only half of the photo?

If a very fast shutter speed is used when taking pictures with the flash with a closed shutter in the focal plane, the second shutter shutter will start moving before the first shutter stops. Thus there will never be a time when the entire movie is revealed simultaneously. Thus, when the flash starts the ignition process, part of the film will be covered by the second screen, and this will be the part that is exposed to the light, and thus its place will become empty on the resulting image. Is it possible to suffer an electric shock through a flash gun, connection cables, or socket?

In some circumstances small electric shocks can occur when the synchronous lead or hot base contacts of a fully charged electronic flash gun come in contact. Injury to some very small shocks may occur through contacts with the hot base of electronic cameras, but this seems to be a rare occurrence and may occur in very wet conditions when hands and the camera are wet, or when a major malfunction or defect occurs in the device. It is prohibited under any circumstances to touch the internal contacts of a gun

Electronic flash because serious shock may occur, especially when using high-capacity devices and in devices that depend on high-voltage batteries for their work. This danger will be diminished at the lower wattage currents used in most flashguns. Unprotected electronic flashguns should not be used in rain and snow. Versatile flashguns should not be used underwater. Only special flashguns designed for underwater operation should be used for this purpose.
