Because the pin hole or convex lens of the camera inverts the image being photographed. A ray of light angled downwards will be registered at the base of the film. A ray angled upwards will be registered at the top of the film. Thus inverting the image. It is easier to

What is the approximate camera resolution required to produce an 8x10 print at 300dpi of a digital photograph without resampling or interpoltating the image?
7.2 megapixels
Do camera obscuras produce negatives or positives of an image?
The camera obscura is the name for a room that produces images on one wall by using a small hole in the opposite wall. Light passes through the hole and creates an image of the outside of the room. Where there is more light outside, a brighter image will be created on the inside. Therefore, the image wil be a positive one. This is the case for all cameras. The image created is always positive. However, in the case of a camera that uses film, the chemical process generates an image on the film that is dark where more light has hit the film and light where less light has hit the film. It is the chemical process that produces the negative image and not the camera itself. All cameras, including a camera obscura, will produce an inverted and reflected image, so that the image is upside down and back to front. The reason is that light travels in straight lines. It is easy to simulate this by drawing several straight lines through a small aperture. You will see that a beam of light coming from one side of the object will end up on the other side of the image.
What are the three basic elements of the video camera?
1) The Diaphragme (iris)- Limits the amount of light that goes into the camera. 2) The Lens- Light passes through the lens to form an inverted image in the camera. 3) Charge Coupled Device (CCD)- Absorbs light and emits electrical signals needed to produce a digital image.
Why are images upside-down in a pinhole camera?
You can figure out why an image in a pinhole camera is upside down if you think about how the light travels to get to the image. Light from an object higher (or the top of the object) than the camera travels in a straight line down to the camera. It goes through the pinhole and continues heading down until it hits the back of the camera. This means that the image of something higher than the camera is now low in the image. The opposite is true for light from an object lower than the camera (or the bottom of the object): it travels to a point higher in the image. Still does answer my question, how did the image get upside down? answer was no concusive.
When you expose a film in a camera the image is formed on the film and What is this image called as?

When an object comes closer to a convex lens what happens to the location of the image?

What three colors are processed by digital camera in order to produce an image?

How can a thermal imaging camera produce a picture in the dark?
it uses infared and heat sensor to make a visible image
What is an optical device that uses a lens to produce a larger and virtual image?
A camera, television, lap top, glasses, psp, claw machine.
Which sensor will detect light when white light shines into the camera?
A camera sensor is typically equipped with a digital image sensor called a CMOS that contains individual pixels that can detect light. When white light shines into the camera, the pixels in the sensor will capture the intensity and color of the light to produce an electronic image.
How can I open an image in Camera Raw?
To open an image in Camera Raw, you can do so by opening the image in Adobe Photoshop and then selecting "Filter" from the menu, followed by "Camera Raw Filter." This will allow you to make adjustments to the image using the Camera Raw interface.
How can I open an image in Camera Raw for editing?
To open an image in Camera Raw for editing, you can either open the image directly in Camera Raw or use Adobe Photoshop to access Camera Raw. In Adobe Photoshop, you can open the image by going to File Open As Camera Raw. This will allow you to make adjustments to the image before finalizing it.
What optical device can produce a real image?
A camera is an optical device that can produce a real image. It does this by focusing light onto a photosensitive surface (like film or a digital sensor) to create a true-to-life representation of the scene being captured.
Who invented the firs camera?
The very first camera was invented by the ancient Greeks and Chinese, but it was in 1816 when Nicephore Niepce captured the very first photographic image from a camera he created. And in 1839, together with Louis Daguerre, they invented a camera that can produce clear pictures.
How to open an image in Camera Raw?
To open an image in Camera Raw, first open Adobe Photoshop. Then, go to File Open and select the image you want to edit. The image will automatically open in Camera Raw for editing.
What are two peripherals that provide image data?
Digital camera and video camera provide image data.
