Common FAQ’s On Camera? Technology Explained!


1) Who invented the camera?

Who invented camera? Johann Zahn designed the first camera in 1685. But the first photograph was clicked by Joseph Nicephore Niepce in the year 1814. It was thousands of years back that an Iraqi scientist Ibn- al- Haytham made a mention of this kind of a device in his book, Book of Optics in 1021.

2) When was DSLR invented?

In 1975 Kodak engineer Steven Sasson invented the first digital still camera, which used a Fairchild 100×100 pixelCCD. On August 25, 1981 Sony unveiled a prototype of the Sony Mavica. This camera was an analog electronic camera that featured interchangeable lenses and a SLR viewfinder.

3) What is sensor on a camera?

A CCD image sensor on a flexible circuit board. … Early analog sensors for visible light were video camera tubes. Currently, used types are semiconductor charge-coupled devices (CCD) or active pixel sensors in complementary metal–oxide–semiconductor (CMOS) or N-type metal-oxide-semiconductor (NMOS, Live MOS) technologies.

4) How do you use Aperture?

If you want to take a picture of a person and have the background be blurry, you’d use shallow depth of field. If you want to take a picture of a sweeping mountain vista, you’d want to use a small aperture size (high f-stop number) so that the entire scene is in sharp focus.

5) How does the aperture affect the image?

By controlling the amount of light entering the camera, your aperture affects your shutter speed, and visa versa. … Choose a larger aperture (f/2.8, f/4, etc) for minimal depth of field and more light filters into the lens, causing your shutter speed to increase.

6) What is ISO and what does it do?

The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The component within your camera that can change sensitivity is called “image sensor” or simply “sensor”.

7) What is ISO range?

In the case of digital cameras, ISO sensitivity is a measure of the camera’s ability to capture light. Digital cameras convert the light that falls on the image sensor into electrical signals for processing. ISO sensitivity is raised by amplifying the signal.

8) How does the ISO affect a picture?

ISO is one of three determining factors of the exposure of a photo, along with aperture and shutter speed. These two affect the lens and exposure time respectively, with theISO affecting the sensor (or film). To be more specific, the ISO determines how well exposed a photo will be by changing the sensitivity.

9) How do digital cameras work?

A digital camera takes light and focuses it via the lens onto a sensor made out of silicon. It is made up of a grid of tiny photosites that are sensitive to light. Each photosite is usually called a pixel, a contraction of “picture element”. There are millions of these individual pixels in the sensor of a DSLR camera.

10) What is an image sensor?

An image sensor is a solid-state device, the part of the camera’s hardware that captures light and converts what you see through a viewfinder or LCD monitor into an image. Think of the sensor as the electronic equivalent of film.

11) What is CMOS image sensor?

CMOS sensors are much less expensive to manufacture than CCD sensors. Both CCD (charge-coupled device) and CMOS (complementary metal-oxide semiconductor) image sensors start at the same point — they have to convert light into electrons.


12) What is an APS H camera?

The number of pixels on the 18.1MP 1D X’s sensor that lie within an APS-H sized box are only about 11MP, or 30% less resolution than with the 16.1MP 1D mkIV. The 1.3x crop factor is linear. Resolution is based on area. A full frame sensor has 1.67 times the area of an APS-H sensor.

13) What is a full frame sensor camera?

‘Full frame’ is the term used to describe a camera with a sensor the same size as a 35mm film negative, measuring 36 x 24mm. Most DSLRs, however, use sensors measuring approximately 24 x 16mm. This is close to the APS-C film format, which is why these are often referred to as ‘APS-C’ cameras.

14) What is a crop sensor DSLR?

This means that if a full frame DSLR like a D800 and a crop-sensor DSLR like a D7100 take the same photo from the same distance, with the same lens and point of view, the D7100 will capture a tighter field of view than the D800. Focal length measurements on lenses are based on the 35mm standard.

15) What is the definition of CCD?

A charge-coupled device (CCD) is a light-sensitive integrated circuit that stores and displays the data for an image in such a way that each pixel (picture element) in the image is converted into an electical charge the intensity of which is related to a color in the color spectrum.

16) What is metering mode?

In photography, the metering mode refers to the way in which a camera determines the exposure. Digital metering feedback. Analog metering feedback (light meter).


17) What is the best DSLR camera for beginners?

  1. Nikon D3300. It’s not the most expensive entry-level DSLR, but we think it’s the best. …

  2. Canon EOS Rebel T6i / Canon EOS 750D.

  3. Nikon D5500.

  4. Canon EOS Rebel T6s / Canon EOS 760D.

  5. Nikon D5300.

  6. Canon EOS Rebel T5i / Canon EOS 700D.

  7. Nikon D3400.

  8. Canon EOS Rebel SL1 / Canon EOS 100D.

18) Which camera is best for professional photography?

In the meantime, here are the best full-frame DSLRs you can buy right now:

  1. Canon EOS 5DS.

  2. Nikon D750.

  3. Nikon D5.

  4. Canon EOS-1D X Mark II.
