How to shoot a textured portrait with a flash?

In daily life, as a photographer, you must be asked by your relatives and friends to take pictures for you. So how do you shoot a textured portrait with a flash? Let's have a look!

Pre-shooting preparation part

Pre-shooting is essential. In the early stage, shooting was the main thing. Shooting theme, shooting plan (time and place, people and things), story version, props, costumes, models, team members, etc. But this paper mainly introduces the technical methods, and the previous ones are very personal, so I won't go into details here.

Shooting part

Introduction of shooting time period: the choice of shooting time period should be determined when shooting plan. This photo was taken at sunset. When the sky turns blue, the details of the cloud will become more obvious. The light ratio will not be very large, nor will it exceed the dynamic range of the camera. In this way, it is easy to take photos with rich details from bright parts to dark parts.

Introduction of shooting location: The choice of shooting location is also determined during the shooting plan. Street, next to red brick wall, diffuse reflection material.

Determination of background environment by photometry

Determine the exposure of the environment. It is equivalent to taking a photo of an ordinary street. Just expose the environment in a familiar way.

First determine the aperture. To take a portrait, the background should be blurred and the aperture should be large, but the whole face should be kept in a clean area, and the aperture should not be too large. I chose aperture 2.5. (The aperture size can be determined according to your own shooting preferences. )

Shutter speed, first of all, to ensure the clarity of the image, shutter speed is not easy to be too slow, usually the safe shutter speed of portrait is faster than 1/50s (not the reciprocal of focal length, it is used for hand-held landscape shooting. )。 Even if a tripod is used, it should not be slower than 1/40, because the camera will not shake, but the person will move slightly, resulting in a decrease in definition. When high-speed synchronization is not applicable, make the shutter speed lower than the camera flash synchronization speed.

ISO adjustment. The aperture has been determined and the shutter speed has an interval range. This can adjust the exposure of the whole picture by adjusting ISO.

Try to use a lower ISO, but don't be afraid to use a higher ISO. Nowadays, the camera has a good sense of height, and the noise of iso2000 picture is also within the acceptable range.

Under normal shooting, that is, non-stylized shooting (deliberately overexposed or underexposed according to the needs of the subject), the general idea of determining the exposure parameters is to expose as correctly as possible under the premise of combining the above-mentioned ISO adjustment principle of aperture shutter, so that the camera can record more details of the bright, dark and middle parts of the background as much as possible. Regardless of the exposure of the characters, the exposure parameters of the characters are all completed in the flash part.

Determination of flash parameters. In this example, the flash is set as follows: Shenniu v850 pulls out the diffuser, adds 80*2000px soft box, and has no color filter. The orientation is at one o'clock, 45 degrees above the figure, and the center of the flexible frame is about 1 meter away from the face.

The idea of setting the flash is to first determine the position, distance, direction and height of the flash from the model. Mainly to master the application of several classic basic lighting schemes in different environments. Including 1 split lighting, 2 loop lighting, 3 Rembrandt lighting, 4 butterfly lighting or Paramount lighting, 5 wide lighting and 6 short lighting. These are recognized classic lighting, which should be mastered and skillfully used.

Then determine the output power of the flash. The exposure of the environment has been determined and the parameters of the camera have been determined. The direction of the flash is also determined, so that the output power of the flash can be adjusted independently. Expose the photo characters correctly. Ensure the integrity of the highlights and dark details of the characters. And the characters will not stand out from the background of the picture too obviously. Characters live in harmony with the background. Sometimes adding a suitable foreground, a foreground in the middle and a level of foreground, composition gives the picture a sense of depth, which will make the characters blend better.

I'm using the flash system. This time, it uses the Shenniu V850 flash and 80*2000px soft box, which can output power remotely. I have always felt that the external shooting of the god cow system is very convenient and easy to use. I recommend this system (ad360 v850 plus FT- 16 trigger remote control).

Many people ask me if I need to use an exposure meter. I think it's because the screen plays now, and the camera can be connected to a notebook or a tablet when shooting (ipad air is recommended for outdoor shooting, covering the srgb color space, and the screen color calibration of ipad air is one of the best in the tablet. ), the photo playback is very convenient, so the exposure instrument is not a necessity. But sometimes an exposure meter is needed to determine the ratio of main light to side light. Or when shooting, the flash output can be quickly determined, and the exposure meter can improve the efficiency. If money is limited, don't buy it. If you have plenty of money, you can spend 2000 photography budget on exposure meters.

Summary of the overall thinking of shooting part

With the preparation and planning in the early stage of shooting, the shooting process is purposeful, and the shooting process is the time to obtain information, so the whole idea is to capture the information we need and get as much information and details as possible. This requires skilled use of various technologies.

The photographer's basic composition techniques (in fact, the composition may be determined in the preparation stage. Skilled application of storyboard, photometry and flash. This is the most basic requirement for photographers or photographers. Only by mastering these points skillfully can we focus on expressing our feelings when shooting. Communicate with models to arouse their emotions and enthusiasm. Pure technology is just a way to realize it. Anyone can master pure technology. What distinguishes every photographer is the way the photos are expressed. This aspect is a very personal matter, which is determined by people's whole growth experience. I think as long as photographers can express themselves correctly through the richness of photography technology, they can be harmonious and different. Photography should let a hundred flowers blossom.
