How does beer shake into foam?

The way to foam beer is to shake it before opening it. If it is photography, foreign bubbles are usually added.

Foam is a common phenomenon, which can be produced by stirring soapy water, and a lot of foam can be produced when a beer bottle is opened. Generally speaking, bubbles that are not produced by pure liquid will burst immediately when they touch each other or overflow from the liquid. Generally speaking, pure water and even pure surfactants can't form elastic films because of the uniformity of surface and interior, so their foams are always unstable.

Main information:

Commercial shooting technique: beer bottles generally have two colors, one is warm brown and the other is cold green. Take Budweiser as an example. The expected effect is to shoot a whole bottle of water droplets, next to a bubbling beer glass.

Visually echo each other, and the picture is fuller. Beer is a kind of drink, and the shooting effect must give people a certain sense of pleasure, or it is as cool as summer heat, thus stimulating consumers' desire to buy.

Shoot a water glass full of beer and foam. It is very important to keep the lighting scheme of bottle shooting and change the original position of beer bottle into glass. The reason for this is that the perspective can be maintained and the perspective will not change. Secondly, the size of the cup and the ratio of beer bottles to real objects will make the effect of later synthesis more natural.

When patting the glass, tell the beer to pour into the glass, don't fill it up, and leave some room for the beer foam. After the lighting arrangement is completed, add foam.
