How film camera work? In this article we will breakdown about the film camera from the moment the shutter button to the finished photograph.
Film cameras might be using an older technology to operate, but in recent days, its uses still popular among photography enthusiasts.
There are a lot of things to why people are still using this piece of device, from the unique image that it produces to a more vintage-looking the device looks.
So, without further ado, let’s find out how a film camera works!
How Film Camera Work?
1. Pressing The Shutter
The process begins with you pressing the camera’s shooting button. And In the past, these buttons were entirely mechanical, using levers and gears to physically trigger the shutter.
2. Opening the Shutter
Before you press the shutter button, light is blocked by internal curtains within the camera, safeguarding the film from accidental exposure.
And by pressing the shutter button triggers them to rapidly open, allowing light to enter the camera. This burst of light acts like a paintbrush, capturing the image onto the film.
3. Light Hitting The Film
Imagine the camera lens as a powerful eye. It gathers incoming light and focuses it precisely, just like a magnifying glass.
This concentrated light then strikes the film, which plays a crucial role, it’s incredibly sensitive to light and acts like a recorder, capturing the light patterns to create a lasting image.
The duration of the shutter’s openness determines how much light reaches the film, ultimately affecting the image’s brightness.
4. Creating a Negative Image
Light hitting the film’s light-sensitive layer, specifically the silver ions, triggers a chemical change that creates a hidden image called a latent image.
However, this image is essentially a negative which means the tones of this image are reversed, and what’s bright in the scene appears dark on film, and vice versa. Additionally, the image is flipped top to bottom.
5. Closing The Shutter
The shutter closes once the moment has been caught on film. This puts an end to the photographic process by preventing light from accessing the film.
Naturally, this does not imply that you can open the camera’s back cover, as doing so will cause light to shine on the film once more and obliterate the previously captured picture. This movie is only watchable in its post-development light.
So there you are some info about how film camera work!
Even though the film camera might be a little bit old-school compared to a newer digital camera, but its always have a special place in the hear of photographers, either a hobbyist or professionals.
But, do you know that a newer digital camera sometime have a wireless technology like bluetooth?
This technology is using a radio frequency technology, in which its uses are strictly regulated especially in Indonesia.
The device that about to sell or distribute in Indonesia, need to undergo several tests to ensure that the radio frequency technology that the device is using is within Indonesian standard.
This type of regulation is the SDPPI Approval, and you can get a lot more to know about this subject, here!
