About the Image(s)
Liquid in basin : Milk base with red food coloring .
Top liquid drops : Plain water with blue food coloring .
A basin that is long enough to allow the camera to focus on both the top and the reflection is required.
A few drops of surfactant (liquid dish soap ) had been added to top liquid to create more water droplets .
First the drop sizes and delay of second drop had been set.
The delay of flash firing is the third variable to create different patterns of water collision.
Note that flash can be aimed at opaque liquid but if the liquid is translucent (plain of only have food coloring in it) then the flash will produce too much glare.
This is a simple 2 drops collision but different colors and angles can produce interesting results too (for me anyway).
In post processing, a brush had been used to brush blue (using white balance) to intensify the color. If you wish to, you can add color using adjustment brush in LR but the color might become more artificial... Generally it is OK to use in non-organic subjects but be careful in nature.
Sony A 6000 90 mm Macro lens ISO 100 4 flashed 1/128 power 1/6 sec

Once again the tightness if not crop choice but the whole image.
This is an old image and I had been struggling with the correct position of the camera. It is a balance between capturing more detail vs getting a bigger image.
I shall take your suggestions and keep trying.

I think that changing the aspect ratio only make in camera crop.
I tried to shoot in 16:9 because I do a lot of videos but find that it is better to crop in editing.
Shall look into it more. Thank you very much.   Posted: 06/28/2020 06:34:25
