This is a second episode from the “Water in product and advertisement photography” series. This time we used the same tank and mix of distilled and sparkling water.
The idea was simple: pouring objects into a water and shooting through the water tank and positioning the camera strictly horizontal. Because we have used carbonated water, the tank must be 100% clean inside: every small piece of dirt on the glass will attract bubbles.
The camera was perpendicular to the subject, meaning we did not need a very deep DOF, the aperture was set to F10. It was enough to have the full object in a focus while out-of focus a tank walls was enough to hide any occasional bubbles on it. For the same reason we used a 180mm Macro lens: longer focus helped us separate the object from a tank walls.
Water in advertisement photography: the pepper and CO2 water.
Speaking ob CO2 bubbles, it was quite important how much soda we’ll use: add it too much, and the bubbles will grow too fast and become too big, leaving photographer no time to get the shot, as the object will loose the bubbles too quickly.
The ideal (for our needs) mix was 70% distilled water and 30% of soda water (no sugar, please:-). With such ratio we were getting a very nice slow bubble buildup on the object. It starts from a mist-like tiny bubbles covering all the object, growing for about 5 minutes before they will start popping-up.
Now, the lighting setup:

Bubbles looks the best when highlighted from the behind, therefore I’ve used two hairlights from both sides.
First (4) was placed form top-behind, second (3) was on a side: no even or symmetrical lighting if we want product to have a volume.
The ratio between these two lights, will be different as well: one light should be at least 2 stops brighter than another: this way we ensure the object won’t look flat.
The top light (2) is to highlight the front of the object. The angle should be very sharp, meaning no light spill on the background behind the tank: we need to keep it dark.
At first I was trying to use a Beauty Dish, but found it too big, light was spilling on the background a lot, which made it gray. Therefore 7” reflector with 10° grid was used.
Background spot (1) was our most powerful light: deep blue gel with 10° spot required a lot of power.
Now, the post-production of the last photo (the bottle): we had two separate shots combined together.
The first one poured into a water, with bubbles all around, and a second one on the same position but without a tank.
later it saved us quite a bit of time; instead of cleaning the label form a bubbles manually, we just applied (via masks) a clean one. Few bubbles were left on a place which made the image look more naturalistic.
