Creative photosensitivity


    Concerts and various events are held in low light, and shoot them hard enough.

    Because of the need to change position all the time and because of the movement of the subject to photograph in these conditions with a slow shutter speed is impractical. The flash does not pass. Not only because of the fact that in this case, the character of lighting, which is carefully selected illuminators, but also because it might interfere with the audience. Organizers usually prohibit the use of flares. Much better in this case raise the sensitivity and open the aperture. You will be surprised with what shutter can shoot at ISO 800 and f / 2.

    How to open the diaphragm?

    In the end, to open the aperture can be nothing more than allowing construct /? lens. Most standard lenses are not very adapted for this purpose and has the aperture ratio f / 3,5- 5,6. More expensive lenses with the same focal range are limiting aperture f 2,8, which is two notches higher than f / 5,6. More options available 50mm standard lens with aperture f / 1,8 or f / 1,4 for three or four steps, wide aperture than standard long-focus edge zooms. Four steps enough to speed shutter with useless values ​​from 1/8 to an acceptable shutter speed of 1/125 sec.

    Of course, when shooting with such diaphragms problems. Quality lenses in such diaphragms is not high, as in contrast and sharpness by, especially at the edges. This may not matter after a bad unsharp images, but we must bear in mind that several holding aperture you mezhet improve the image. There are supporters of the following approach to the use of high-aperture lens: they argue that the lens aperture of 1.4 must be removed without opening the aperture more than up to the value f / 2,8, not to lose money.

    On the open aperture you will not have a large depth of field, making it difficult to focus, especially when moving objects. Helps continuous autofocus, but only if you have it fast enough. In this situation, it is better not to use AF tracking, and more often to look at the result of the shooting. This is especially important when you are shooting at close range. Then it is better to slightly increase the depth of field by increasing the sensitivity.

    With some delay?

    Characteristics of digital cameras with high sensitivity is significantly improved compared to previous years and the image processing and noise reduction algorithms. Noise – a major problem when dealing with high sensitivity. When the signal from the sensor is amplified, and the amplified noises corresponding electronic circuits. Some cameras cope with noise at higher sensitivities are better than others. When shooting sports and action SLR Canon and Nikon produce excellent results up to ISO 6400 and allow you to set the maximum values ​​of up to 102000 ISO.

    tested my camera and set the limit to which preserves the normal image quality. Shooting in black and white adds a noise similar to the nature of film grain in the subsequent editing of images.

    Colouring light

    Pictures are divided into those who love and hate their flash. Note, who hates, are under the impression of bad experiences, no doubt caused by the use of built-in flash units automatically. If you manage a flash, you can get effects that no other way.

    One embodiment of such a flash – light staining. This technique consists of opening the shutter for a long time, during which the shooting scene is illuminated by flashes of light, activated manually. This stunning effect, and he can give fantastic results, especially if a long exposure is captured and the night sky. If your flash attached to the color filters, then try to cover different parts of the scene.

    You may need to set flashes in manual mode and customize the power to get the proper exposure at the selected aperture. This is another example of the method of trial and error, so do a few test shots and monitor the result on the display using the histogram to avoid overexposed areas.

    Architecture – ideal subject for such a reception application flares, and if you find any broken buildings, the effect may be even stronger. Walk around, look for nooks and even try to make a flash inside the ruins, if possible. You can also use other sources of light, such as LED lights, you can make great light patterns in the air.
