Why do you need a flash to take pictures?

Lead: At the beginning, we usually only had one lamp, so the lighting of a single lamp can be said to be the simplest or the most basic. Lighting can be complicated. However, let's start with the basic single lamp technology.

Before learning flashing lights, you need to know why you need to use flashing lights. I believe most people know why they need a flash. The simplest reason is that the light in the scene is not good. The other is a common technique used by photographers, that is, deliberately changing the light at the scene to create photos with different general visual experience, that is? Dramatic drama? .

Light trigger is the simplest and most convenient way to escape from the flash, especially the original flash can also be TTL and high-speed synchronization. But the biggest disadvantage is that the position of the sensing point can't sense light and it is easy to trigger.

The wireless broadcast flasher is another good way to flash off the plane. Wireless RF flasher has a more expensive brand like Pocket Wizard, which has the advantage of supporting TTL and high-speed synchronization, but it is expensive. However, there are also very cheap brands on the market, just a few hundred dollars, such as Yongnuo. Besides not being able to synchronize TTL at high speed, it's really useful. Canon's latest flashing light series has undoubtedly solved most of the flashover problems, which can be said to be quite good products. I hope Nikon will follow up as soon as possible.

The quality of light is a very laborious exercise, because the lamp tube of small flash is very small, so the quality of light is not good and the output is low. Creating high-quality light requires a lot of additional equipment to assist.

The first basic problem of lighting is to find the source of Chu Guang, especially in outdoor environment. You must first find out where the light should come from, and then do the thinking and design of lighting according to this logic.

Just like this photo is actually to make the exposure outside the window correct, in fact, there is almost no light in the room, almost all black. But because there is a desk lamp above the main body, a simple flash is added from the direction of the lamp. Of course, this photo can be improved in many ways, but it reflects the light logic well. The more logical your flashing lights are, the easier it is for you to hide your illuminated traces.

Although it is easy to take pictures on cloudy days, there will always be situations where the light is too flat. Sometimes, except the subject can't jump out, the skin color of the face will be less pleasing. It is very simple and easy to catch the light on a cloudy day or in poor light, because the light of the flash can be felt with a little supplement, and the output of a small flash is absolutely enough.

This photo uses an SB900 with ezybox of Lastolite to capture the horizontal light outside the right side of the picture. Just a little, let the subject jump out a little.

This photo was taken entirely by joe McNally himself, and it was taken in the room at home, which is simple and easy to do.

If you need a beautiful lamp, and there are not many lamps, then the simplest thing is to find light-transmitting materials around your life to use. When this photo was taken, it was actually raining heavily outside the rear window, and the whole window was too dark, so there was little light coming in from the window (note: similarly, if the natural light is excellent, sometimes there is no need for extra flashing lights). Therefore, for the window with SB900 outside the window, the texture of light is pleasing to the eye.

Jumping lights is the fastest way to generate a large area of light, and it is often a good way to distribute light, especially when you just need a uniform light to capture a picture that doesn't need too much personality. In fact, there is a large French window on the right side of this photo, so there is quite a lot of ambient light on the right side of the photo. Therefore, when jumping lights, we should catch the light on the left, and try our best to balance the two to think. Generally speaking, it takes two flashlights to jump all over a room. The output of two circuit breakers does not have to be exactly the same, and it can be a very simple level.

Flash has the color temperature of flash, and all kinds of artificial light sources in life also have different color temperatures, so there are so many different filters to match the flash, but it seems that many people will ignore the filter. In this photo, the position of the newcomer station is almost completely black under such exposure conditions, and it needs to be scratched.

From the logic of light, this photo will feel that the light should come from the chandelier next to it, so it is good that the color of the flash matches this light. This photo uses a full concentration orange filter (full CTO).
