LEARNING TO REMOVE DROPS

Every photographer sooner or later tries to shoot drops. Most often this is the classic form (short drops) or crowns. Looking ahead, I will say: I take pictures with the equipment that controls the time of falling drops and synchronizes the camera shutter. But this does not mean that the trigger creates ready-made forms, as many mistakenly believe. Sergey Tolmachyov tells.

There are a lot of nuances in shooting drops, and any beginner simply does not know and does not even know what he will encounter. I will try to get you as close as possible to this amazing type of shooting.

I always start with the preparation of water. We need a certain viscosity, which can be achieved using special food additives (thickeners). Information about them can be found on my website www.prophotosite.com. I advise you to always filter the liquid from the grains, otherwise they will all be visible on the drop. For giving of color food dyes, acrylic paints, fluorescent, luminescent paints are used. I will not write about proportions, it will be more interesting for you to experiment.

After cooking the liquid, adjust the light. We need four flashes with helium filters (for coloring the background) and milky plexiglass. Plexiglass set at a slight angle so that the light falls on the water. For plexiglass for better dispersion and a uniform gradient, we install 4 flashes of YN560-III with a power of 1/32 = 1/12626 c. As we see, this is enough to freeze without blurring the picture. In high-speed photography, freezing of fast processes is carried out by a short light pulse. The shorter it is, the less blurry the image will be.

Another flash with a helium filter is placed under the tray to highlight the drop itself. Outbreaks for convenience are divided into groups. We manage them through a wireless controller.

Camera settings are as follows: aperture F16, ISO 250, shutter speed 1/125, all flashes 1/32 of full power.

Settings for trigger:
first drop drop: drop volume – 65 ms, valve opening time – 100 ms,
the second drop drops: the drop volume is 85 ms, the valve opening time is 24 ms, the shutter delay is 385 ms.
Remember that all trigger settings are individual due to the factors described below, and they also affect the result.

The main nuances that need attention:
The drop height in this case was 65 cm (the value may vary depending on the tasks).
The shape of the droplets will be affected by the following: the viscosity of the fluid, the temperature of the water and the environment used, and even the depth of the pan.
Surface tension of water. Remove the surface tension using a single drop of detergent.
Good luck! I believe that you will succeed.
