It used to be the ASA rating, but now its the ISO rating, the higher the number, the more sensitive the film is. e.g. 100 for daylight 400 for nightlight as an example.
The emulsion is the coating on a film in which the image is formed.

The emulsion side of film is important in developing photographs because it contains light-sensitive chemicals that capture and record the image. When the film is exposed to light, the emulsion side reacts to create a latent image that can be developed into a visible photograph.
The emulsion on the film of a camera is where the image is focused and captured. In the eye that function is performed by the retina.

In screen printing - Direct emulsion is a liquid substance, that when coated onto a mesh with a scoop coater, dries to form a photosensitive film. Indirect emulsion is a sheet of dry emulsion that is typically adhered to mesh with a solvent. When either emulsion is applied mesh, and is dry, it can be exposed to light and creates a stencil of the art to be printed.
To apply polaroid emulsion and create instant photographs, a chemical mixture is spread onto a film base. When the photo is taken, the emulsion reacts to light and captures the image. The film is then passed through rollers to spread the chemicals evenly, developing the picture within minutes.
I think it was first done in 2006. The question would be more accurate changed from "when will" to "when did" and removing the ever. = When did digital photographic technology surpass the quality of photographic film emulsion? =
The lens of the eye is similar to emulsion because it helps focus light onto the retina, much like how emulsion focuses light onto the film or digital sensor in a camera. Both the lens and emulsion play important roles in capturing and processing visual information.
ASA and ISO both refer to film speed, or the film's sensitivity to light. ASA is the American standard, while ISO is the international standard. They essentially measure the same thing, which is the film's sensitivity to light, with higher numbers indicating a faster film speed.
The standard mixing ratio of photo emulsion and sensitizer is typically 1 part sensitizer to 12 parts photo emulsion. This combination allows for proper light sensitivity and adhesion to the screen mesh for effective screen printing. It is important to mix thoroughly and follow the manufacturer's instructions for best results.
