How to take pictures with a flash in the afternoon and why in general a flash in the afternoon?
The question seems pointless, but when it comes to practice, it turns out that a flash even on the sunniest day can be an indispensable tool in the hands of the photographer.
In general, it is generally accepted that a flash helps when there is little light, i.e. serves as an additional light source in poor light - in the evening, at night, in the house, in the shade of trees, in cloudy weather. But when there is a lot of light - it can and should be used too. As they say - there is never much good light.
So during the day, a flash is needed as soften shadows from the sun or other strong and harsh light sources. Mostly flash during the day use for photographing portraits. The harsh light of the sun can make very strong shadows on people's faces. A flash can soften these shadows.
True, there are day flash restrictions. For photographing portraits, it is recommended to use fast fixed lenses. For example, a lens with an aperture of F2.8 and a set value of ISO 200 will require on a sunny day excerpts about 1 / 2000s-1 / 4000s. But there is flash sync concept with a camera shutter and often this synchronization rests against a certain limit. Basically, built-in flashes can work with shutter speeds of at least 1/200, 1 / 250s, or 1 / 320s, of course there are exceptions - this Nikon D40, D70, D70s, D1h etc. which can use shutter speeds up to 1/500 s, but still, they are too long excerptsto take pictures in daylight. But even if you have external flashYou can take pictures at shorter shutter speeds only if your camera allows it.
Attention: None of the built-in flash on any of the central controllers can work normally with shutter speeds shorter than 1 \ 500s. The built-in flash does not have a single CZK quick sync mode.
Attention: High-speed sync mode is available on many cameras only in P, A, S, M mode.
In order to be able to use a flash with very short shutter speeds, was created quick sync mode, which is called differently for different cameras of different manufacturers. For Nikon, this is FP (fast pulse, fast sync), it allows you to use flashes and synchronize them with shutter speeds up to 1 / 8000s.
In order to be able to use this mode - need:
- For the camera to support fast sync mode
- For the flash to support fast sync
Not all cameras can use this mode - they mainly include advanced amateur cameras and all full-frame digital mirrors.
Here is the exact list of CZK Nikon that support mode FP:
As you can see, the choice among Nikon cameras is small. Younger cameras of this mode do not have, which will not allow taking photos with a flash and a small shutter speed. But this is not a problem, since you can use neutral filters for decreasing excerpts. Polarizing filters also reduce shutter speed. Usually the need for flash during the day is very small.
Not all flash units support this mode. – small external flashes SB-300, SB-400 do not know how to work in this mode. Nikon's FP mode works fine SB-500, SB-600, SB-700, SB-800, SB-900, SB-910, SB-5000. These flashes can shoot shutter speeds up to 1/8000. Many third party flashes also support FP mode, but it is often referred to by a different name such as flash Metz Mecablitz 48AF-1 for Nikon has an HSS mode that is completely similar to FP mode.
When photographing during the day with a flash, you need to remember that short excerpts and bright lighting requires a lot of flash energy. Funnily enough, high-speed sync flash recharges faster than normal flash, due to the unusual firing system in FP mode.
If you have an advanced camera with fast sync mode, then most likely there command mode for the built-in flash. This will allow you to use your external flash in remote control mode using the protocol Nikon CLS. That is, it will be possible to give light at the right angle and thereby create an excellent art photo. I advise you to experiment with photos with a flash against the sun to understand how effective the flash is in the daytime. For example, in the photo below, the girl lights up with a back (strong side) light, if I did not use the flash, I would get a dark face. The flash turned out quite differently. True, using the flash on the camera can lead to a loss of volume in the photograph.
Is it worth using flash diffusers, reflective cards - you need to look at the circumstances. As practice shows, sometimes very effective flash on the forehead in daylight, which is unacceptable when photographing people, for example, at night. When using a diffuser, the leading number of the flash is lost, which, even with fast synchronization, is less than usual. With fast synchronization, the flash makes a series of pulses with a huge frequency (of the order of 50 KHz), the human eye does not see this, but it decreases the distance from which the flash can illuminate the subject. You can read how to increase the flash range in the section Tricks 7.
Flash during the day is just as useful as a flash at night, the main thing is to set it up correctly and remember that to get good shots it would be nice to have a quick sync mode between flash and camera.
