How does a SLR camera shoot water droplets?

Introduction course of SLR camera how to shoot water droplets

Macro head tripod is a must. If it is a water drop on the surface of a static object, just polish it.

If it is dripping, you need a quick shutter. Try a shutter above 1000. If you can't catch it, you can shoot it at high speed. Of course, a high-speed shutter means that you need a light source with enough brightness to reduce ISO.

Try dozens of times and you should be satisfied.

How to shoot water droplets with SLR?

Hello! ! ! The freeze-frame technology used when shooting high-speed subjects such as water droplets does not use the so-called shutter time to determine the exposure to freeze the picture! The way to shoot water droplets is the skill of long exposure! Why exposure for a long time? Here's the principle. For example, you set the exposure time of the camera to 2 seconds, but in the current scene, 2 seconds is underexposed. So if you shoot directly like this, you can get a completely black picture. Then you use an external flash to participate in the exposure, because the actual lighting time of the flash is directly related to its output. Even if the flash is fully output, it will soon catch up with the professional machine's 8000 minutes 1 second (the fewer flashes, the faster the flash time, and the standard time will generally be written in the instruction manual of the flash). Because of the above settings, the so-called exposure time is actually only one tenth of a second when the flash is flashing, so the picture of water droplets can be fixed. In addition to flashing for more than one tenth of a second, the camera can be exposed in 2 seconds. Because the exposure of the original setting is seriously insufficient, the flash does not leave an image after it shines, so that only the image when it flashes can get the freeze-frame picture of the water drop! This exposure time is actually the lighting time of the flash, because the lighting time is very short, so it is enough to freeze the image of the camera shutter limit! My Baidu space has photos of water droplets I took. Interested parties can have a look! Or go to the link below to see, it's a picture when I shoot water droplets! /...0

How to shoot water droplets with SLR?

If you are not familiar with it, you can try TV mode. Simply put, put the shutter as quickly as possible. Generally, the SLR is 1/4000, and the slightly advanced SLR can reach 1/8000. I usually use av mode, and the aperture is basically adjusted to the minimum, and the iso is also the lowest. At this time, the shutter is basically 1/8000. If you are not satisfied, just wait for the lights to dim. Taking pictures requires patience.

How to shoot wonderful water droplets with primary SLR

I don't know if you want to shoot the water droplets below.

If it's this kind of water drop, you only need a macro lens. If there is no macro lens, shoot with the longest focal length and large aperture. This kind of photo usually has a colorful background to set off the crystal water droplets, so you should also consider framing, such as choosing a colorful background as much as possible and shooting against the light as much as possible.

If it's the photo below,

It may be more difficult, because static water droplets can be discovered with the naked eye first, and after discovery,

This dynamic water drop may require more imagination and a sharper perspective.

How to shoot water droplets on the glass with a SLR! For example, the picture below.

Focus manually and set the lens switch to MF.

Because the glass is perspective, it is not easy to focus when focusing automatically.

When focusing, focus on the water droplets on the glass.

Or the arc uses aperture priority mode, and the aperture setting should be large to blur the background.

The lens should be as close to the water droplets as possible, and the background should be blurred as much as possible.

Only in this way can we achieve such an effect.

Poke, you can use the function inside the light and shadow magician to set a satisfactory one and get it in the photo.

Such photos basically don't need PS.

How to shoot water droplets well

Necessary equipment:

Camera: An ordinary SLR camera will do. I was shooting with Nikon D5000. Note that the camera continuous shooting is not suitable for shooting water droplets, and the shooting mode should be adjusted to single shot. It is best to use RAW as the recording format. Generally, the light conditions for shooting water droplets are bright, so the lowest ISO is used for shooting (to ensure fine picture quality). Note that if an external flash is used, the camera should support FP high-speed synchronization, which will be more helpful for capturing water droplets (unfortunately, my D5000 does not support FP, and there is no external flash, so I will shoot with the synchronous speed of the internal flash 1/200s).

Lens: Macro is recommended. I use Longteng 90 miniature camera. Other macro lenses recommend a longer focal length, for example, the 50mm macro distance is too close to the water droplets, which is easy to wet the equipment. If there is no macro, the telephoto end of the telephoto lens can also be used (adding a range extender or a high-quality close-up circle is also good). Pay attention to manual focusing and increase the depth of field with a small aperture.

Tripod: A general tripod can do it, and there is no special requirement. One thing you may need to pay attention to is the size of the tripod, which depends on your shooting location!

Cable release: This better be (I'm useless, so I almost got my camera wet).

Cable release can avoid direct contact between wet hands and the camera, and can also focus on capturing pictures. Of course, if you don't use it, just dry your hands when you press the shutter, hehe.

Flash: It is recommended to use an external flash, preferably two (depending on how many meters you have). One is installed at the top of the machine, and the other is parallel to the water surface, so that the water droplets will have a more three-dimensional effect. Of course, depending on the combination effect, the lighting can be used in different ways. If there is only one flash, it can be placed on the top of the machine or illuminated by water droplets from the side. Pay attention to adjust the amount of light. You can also get good results by using the internal flash of the fuselage. Just remember to remove the lens cover to avoid shadow formation, and the maximum shutter synchronization speed will be reduced to about 1/200s, which will be worse than the water droplets recorded by the high-speed external flash of 1/500s or even higher.

Others: colored pots, iron pans (black flat-bottomed), transparent cups, some colored paper, CD sheets and rags. Location: the bathroom or kitchen at home can be used. My team was shot in the kitchen. If possible, you can also set up your own dripping table (hang a bottle full of water upside down, drill a small hole in the bottle cap to drip water, remember to drill one on the bottle body to keep the pressure so that the water can drip down). As for how to set it up, it depends on the tools at home. I use the faucet in the kitchen to catch water drops.

Shooting process:

Adjust the faucet to drip water, preferably about one drop per second, and drip evenly into the basin. Pay attention to the falling height of about 30 cm, so that the spray is full and will not splash, which is suitable for shooting. The color of washbasin is basically the background color of shooting. You can shoot it when the basin is full, which makes it clearer, or you can shoot it when a very shallow layer of water has just been stored, and the splash will look better, depending on what you have tried.

Adjust the height of the tripod so that the camera is as level as possible with the water. If you shoot from above, it is difficult to freeze the movement of water droplets.

Focus manually after the tripod is fixed. Because the contrast of the water drop itself is very small and difficult to identify, you can put a pencil where the water drop falls, focus it and take it away.

About the magnification of the lens. Generally, the ratio of one to one is too large, and the composition is easy to be incomplete. Generally, one pair of two or one pair of three is more suitable, which is more conducive to capturing the trajectory of water droplets in the air. If the scale is too small, the background such as the edge of the basin will be photographed. Please pay attention to adjustment!

Next is the camera settings. Shoot with a single sheet, the sensitivity is the lowest, and the aperture should be reduced to f8 to f22. The power of the flash should be adjusted by itself. I use the built-in flash, and I can get good results by adding 1.0 steps. If you use a flash, you can turn on the camera FP function (if supported) and raise the shutter.

Other notes: The four pictures shown in the figure were all taken at 1/200s, f 18 and iso 200, with the same parameters, but different effects can be obtained. The effect of 1P is a common composition, which just records the moment when the water drops are about to leave the water surface. At 2P, the water drop has left the water surface, while at 3P, the water drop has just fallen into the water. Concentration effect and composition can be used in water droplet shooting, but attention should be paid to shutter lag and exposure time. Although it is short, it will also affect the shape of water droplets, so it is necessary to take more photos to better grasp it. As for 4P, the color is different from the previous one, but it is actually original ... >>

Solve how to shoot moving objects, such as water droplets.

Usually, deliberately photographing the instantaneous state of an object requires some auxiliary equipment, because people's reaction speed is limited.

Adjust the focal length and aperture in advance. In a dark environment, as for the camera door B (the shutter is always open and always exposed), the sound sensor is used to control the flash. When the water drops into the water, it will produce sound, and the sensor will start to trigger the flash. When the shutter is open, the picture will be exposed on the camera negative or CCD. In a dark environment, close the shutter and shoot.

Usually the camera is a professional SLR camera, and ordinary card machines and mobile phones can't play this.

This is how the water falls into the water and the bullet leaves the gun chamber.

How to shoot water drops on the glass window with Canon 700D (transparent object)?

I don't know whether to shoot water droplets or windows with water droplets. As far as water droplets are concerned, the key is light. The surface of water droplets is complex, and the effect is different with different incident angles. The lens should have a large aperture, preferably a macro. Adjusting the adhesion of glass surface can control the size of water droplets.

Friends who play photography come in (close-up of water droplets)

The difficulty of shooting water droplets lies in the synchronous trigger of strong points.

I've photographed water droplets before, and I used strongpoint synchronous trigger (of course, you can set exactly how many milliseconds the water droplets lag to trigger the flash). In a completely dark environment, open the camera door B, because in a completely dark environment, the photoreceptor is not sensitive. When the water drops fall, strongpoint will be triggered, and the camera will only capture the image of the flash moment of strongpoint. The flash peak value of strongpoint is generally from a few thousandths of a second to 65,438+0/50,000 seconds, which makes the water drop "solidify" instantly when it falls. Similarly, the same principle is used to photograph the moment when a bullet flies out.

So it doesn't matter how many seconds your camera sets the exposure speed, as long as the shutter speed of the SLR camera is lower than the flash synchronization speed (generally 1/250s). It doesn't matter if it is set to 1 second, 2 seconds, or 1/50s, or 1/80s.

Exposure is controlled by the size of the aperture.

In this use environment, the principle of reciprocity failure is used.
