: Move colored transparencies

There is another type of transfer that you can use in your photographic work, which is the transfer of transparencies (slides). It is completely different from any other type of transportation

due to the nature of the origin. As you know, transparencies are seen when light is passed through them. Therefore, we cannot hang it on the wall or put it on the table in preparation for moving it, as we used to do in the past

The method of transmitting transparency is similar to the method of seeing it, as a light passes through one end of it, while a camera is placed at the other end to photograph it. If you have a Projector, you can easily transfer transparencies. Place the transparency you want to transfer on the white display and place the light projector behind the screen, adjust the exposure by the exposure meter, and take a picture of the transparency in the manner previously described in this chapter. To ensure you get a well-toned image, limit your exposure one stop lower and one stop higher than the meter indicates.

There is a better way than this to transfer the transparencies represented by using a special transfer machine that connects to the camera lens directly or to the body of the camera after removing the lens from it, where the transparencies are fixed on a special holder at the end of the transfer machine and the transfer is done by the light that passes through the transparency and the camera is set in this state as if the picture is taken in the normal way. If you own a camera with a TTL exposure system, this system is useful. Exposure through the lens - a good exposure. Also, the flash unit here keeps exposure within reasonable limits and balances the level of illumination. Attention must be paid to color temperature when transferring to a color film. In addition to the need to use a neutral film with tungsten, a color temperature filter must be used most of the time. Acolor Temperature Filter In order to obtain a useful color representation. She is

correct . Close-up equipment is an essential means of all types of transportation. If you are using bellows or extension rings, remember to adjust for light loss. The appropriate exposure is usually about two or three stops above what the exposure meter indicates. But if you use close-up photography lenses, you do not need lighting compensation.

Still life photography:

There are many areas of close-up photography other than the field of transport. Ordinary objects in our daily lives look different when enlarged. And this is what it looks like when you mount your close-up equipment on your camera and look through the viewfinder at those things. Try it, and you will discover another field of photography that you did not know before. Salt atoms or certain parts of a flower will turn into a wonderful painting in this way. All you need is a little creativity and intelligent control of the lighting. The main problem with close-up photography is the depth of field. It will get so shallow that when photographing the petals of a flower, its stalk will appear out of focus! . You must be content with this shallow depth of field because you cannot solve it.

And unlike transportation, where the depth of field is of no great importance because you are a flat plane with two dimensions. The depth of field is important here because the photographed subjects have three dimensions. If you use blowers or couplings, you will lose some control over them here. The exposure compensation you have to make will reduce the effective speed of the used film by two shot stops

In order to get the appropriate depth of field, you have to resort to long-term exposure, unless the photographed subject is moving - such as an ant or a butterfly, for example - and every time you resort to using a fast shutter speed, the depth of field weakens again.

In addition to this, the proximity of the lens to the subject will exaggerate the movement, to the extent that any vibration of the camera, no matter how slight, will be recorded on the film. So you have to use a tripod dedicated to close-up photography. The more stable the camera, the better. And don't forget to use the launch cord as well.

Exposing small subjects needs special attention. The small size of the subject that the background will affect the reading of the subject. The best way to prevent this is by measuring the exposure from a subject of the same color and subject to the same lighting, but greater in mean

Size Give a full exposure to ensure rich detail in the shadows, which is essential in close-up photography.

You can increase the intensity of the lighting by using a flood light lamp or a flash unit. This will fill in the shadows and enrich them with detail. It also helps to increase the depth of field, which is

The most important thing here

There is a self-contained world waiting for you to discover it through a close-up lens. Try it and you will be amazed at the results you will achieve.
