Photography Techniques and Equipment

Silver bromide, a soft, pale-yellow, water-insoluble salt is well known for its unusual sensitivity to light. This property has allowed silver halides to become the basis of modern photographic materials.

Polaroid Corporation introduced instant photography in 1948 with their Land Camera, which could develop photographs within minutes. This revolutionary technology allowed users to see their photos immediately after taking them, unlike traditional film that required processing. Kodak, Fuji, and Konica were all photography companies, but they did not introduce instant photography technology.

Yes, it is the correct answer. A pinhole camera is composed of two boxes. One of the boxes fits snugly inside the other box and can be slid to and fro.

Yes, it is the correct answer. One can get an inverted and real image in a pinhole camera. A pinhole camera is a simple camera without a lens and with a single small aperture, a pinhole. Light from a scene passes through this single point and projects an inverted image on the opposite side of the box.

This is the correct answer as the statement is false. Image is real in pinhole camera.

This is the correct answer. The image is real and inverted.

This is the correct answer. Screen is translucent in pinhole camera.

 Camera is used for taking photo and tap is used for taking water.

Persistence of vision refers to the phenomenon where the human eye retains an image for about 1/16th of a second after it disappears. Cinema exploits this by showing sequential frames at 24 frames per second, creating the illusion of continuous motion.

This is the correct option as if the pinhole in a pinhole camera becomes bigger, the image formed will be inverted and blurred. It is due to the fact that when more than one ray will enter the camera from the given point, it will result in the formation of two or more images overlapping one another. This will result in a blurred image.

This is the correct option as these are the characteristics of image in a pinhole camera. The image formed is upside down and very small as compared to the object.

For the image to be visible, we always require two things. 1. An opaque object 2. Source of light So vehicle in sunlight, sun and ball during noon are all that can be imaged by a pin hole camera but trees during night do not have any source of light so these can not be imaged.

To make a pinhole camera, one needs two cardboard boxes a scale to measure the length to cut out the boxes and a tracing paper which acts as a translucent screen in the camera.

Silver iodide is used in photography because it darkens when exposed to light.

On aerial photographs, the '+' symbols are fiducial marks used to locate the principal point of the photograph.
