One of the important reasons for many photographic friends who are dedicated to the "magic lamp" is that the TTL ability of modern flash is so convenient that the flash can be used without too much understanding of the principles and techniques, so that the light can be compensated approximately to the right degree. Including i-TTL, e-TTL, etc., are the products of this technology under the convenient light supplement. However, senior photographers can not rely on the TTL mode of flash for a long time. In more occasions, we need M mode to control the output, light quantity, angle of flash stably and directly. Now let's talk about the reality and necessity of Flash M mode.
Flash TTL mode, there are at least a few common misjudgments
· When the scene is gray tone, the misjudgement needs to use larger flash power. · For example, some Japanese classrooms using black building materials are easy to misjudge at this time. · In night scene shooting, when there is a darker, no light scene, the flash will tend to use greater efforts to make the main body and scene brighter. · Use jump lamp and pull up diffuser. · At this time, different brands of flash, there will be different reactions. For example, Nikon flash usually judges the use of jump lights, while Nissin flash will use a stronger output. · When backlighting, especially the demand of pressing (compensating) light, the flash usually does not know to compensate the main body with greater effort. At this time, it is also necessary to use M mode or compensate the output of the flash to increase the lighting of the flash.
From this, we can know that the use of flash M mode is necessary, we can adjust the output according to the situation at that time. As long as you are familiar with the M mode of flash, you can create more varied and more desirable shooting results.
The best way to compensate for the flash is to use the flash to invisibly compensate for the light, but don't notice that the flash is compensating for the light, and don't leave any shadow marks.
Such scenes are gray and dark, TTL often misjudges, M mode is the kingdom.
Of course, in M mode, the most worrying thing for photographers is the drastic changes of scene light, such as the constant sunny weather, the sudden sunrise, the sudden clouds and sunshine, which is quite a severe challenge. But when the light conditions change, experienced photographers will be able to immediately detect, and can immediately change the output of the flash. When you are really unsure, switch to TTL mode and solve it with +/- EV. For the following images, the camera uses M mode and the flash uses M mode. Climate: Cloudy and sunny weather, for your reference.
Suddenly when the sun comes out, the photographer must immediately detect the change of light, adjust the camera and flash.
Flash lights also help the eyes.
For white clothes, it also has the function of smoothing high contrast.
