How does 750d Jia shoot water droplets?

Many photographers have the experience of shooting water droplets, such as the capture of milk crowns. Flash was also used for lighting when shooting, and the camera shutter was even as high as a few thousandths of a second, but the water droplets were still blurred.

There are two common reasons for blurring: one is focusing, preset depth of field deviation or dripping position deviation; The second is the exposure mode. The technology we recommend is to slow down the camera shutter in a dark shooting environment and use the flash time of the flash as the real exposure time. The gray bar in the above picture represents the shutter time and the red bar represents the flash time. Generally, when the flash intensity of manual output is116 ~1/64, the flash time is tens of thousands of seconds, which is far beyond the reach of mechanical shutter. So it doesn't matter what the shutter speed of the camera is set. Of course, not really, because if the camera shutter is set too high, the flash will become a high-speed synchronous strobe, and it is generally safe to control it at 30/1-160/1sec. The 30/ 1 in the above picture is purely a personal habit.

Correct the misunderstanding: it is not necessary to cure water droplets with a high-speed shutter, because the real exposure time is actually the flash time.

2. Equipment preparation

Equipment preparation: camera, macro lens, flash, tripod, cable releaser, suitable container, dropper and fixing frame.

No matter what model it is, the SLR controls the aperture shutter in the range of M, the white balance is set to flash mode, and the IOS control is within 400 to reduce the picture noise. Macro lens can provide higher magnification and get better details. A focal length above 100MM can obtain a better shooting distance and prevent liquid from splashing on the lens. Aperture recommendation F 16-F22. Before the focus range of the macro lens, the liquid will be empty if the aperture is too large, and the image quality will be affected if the aperture is too small. The container can be a wide and long basin, and I personally recommend a pure white square plate. Or a transparent glass container.

1. Lighting

Very good results can be obtained with a single lamp. The flash uses M output, and my usual output is116 ~1/64. Opaque liquids such as milk can be placed with a flash on the front. As shown in the figure.

When shooting transparent liquid, you can put the flash behind the liquid. White acrylic or PVC board is placed in the middle, which plays the role of soft light and background. draw

2. Choice of seats

Common shooting angles:

1, horizontal shooting, can better show the splash shape of liquid, and the background is easier to control (pictured).

2. Oblique shooting (about 30 degrees) can easily get beautiful liquid reflection, but it takes more time to control the background processing. Otherwise, the edge of the container will easily destroy the aesthetic feeling of the picture. Looking up and down, it is completely different.

3. Focus issues

Presetting the focus in the early stage of shooting is also an important shooting skill. First, fix the dropper, which is the role of the chemical realization framework. Then, when the dropper drips liquid, a water stain will be formed on the desktop, and a reference object, such as a nut or a pen, can be placed at the specific dripping position. Set the camera to the M manual focus position and focus the lens on the reference object. After focusing, take away the reference object and you can shoot the focus of the water drop.
