Cameras

People use cameras to document everyday life as well as special occasions. Cameras are used to record the growth of babies to adults and to forever capture beautiful scenery.

No, roman aqueducts are not used today we use pipes today instead. Note that one aqueduct in Rome, the Aqua Virgo (now called Acqua Vergine in Italian) is still used to supply the fountains of the city centre, including three famous ones: the Trevi fountain, the Barcaccia (the boat-shaped fountain at the bottom of the Spanish Steps) and the fountain of Quattro Fiumi in Piazza Navona. It is no longer used to supply drinking water for much of the city centre, but this is only due to pollution, not lack of power. It can do this without pumps because of the significant difference in altitude between the Pincian Hill area and the lowland of the city centre. It works beautifully, as shown by the impressive gush of water at the Trevi fountain.

Yes, we use pipes and pumps today in the US and other "modern" countries, but in Latin class (about 28 years ago) we were taught that ancient Roman aqueducts still supplied water to some European communities. Perhaps the EU (European Union) has "improved" this situation since, but the aqueduct required only the immutable force of gravity, as water flows to the lowest point, while our modern system requires electric power to force the water through the pipes. It is a dubious improvement in times of power failure.

Eastman didn't invent the camera, he made it more available to the public by making a camera that used film instead of glass plates. For a little history on the camera and Eastman, click on the related link.

Photocopiers replaced several less-versatile machines, including the mimeograph, a nasty monster that used a typed template on a drum. Ink inside the drum flowed out through openings made by the typewriter, and onto paper as the drum rotated over it. Those of us who used them were very happy to see the first photocopiers, believe me.

It served to take away the romance of battle and show the grim realities of war. It was the first time people, other than eyewitnesses, saw the death and destruction.

Many 20th century painters have named Cézanne as 'the father of us all.'

It's doubtful. The surveillance cameras are there to protect breaking and entering. Anything over five stories high and there are surveillance cameras you may have a fighting chance. Most thieves are lazy and want to hit the lower and easier places to get at.

There are three different speeds here.The average speed of electrons - whether there is a current or not - is a significant fraction of the speed of light. That speed depends on the temperature. (The average VELOCITY of course is zero if there is no current, since as many electrons will go in one direction as in another.)

The drift velocity (the average velocity) of the electrons is a small fraction of a millimeter per second. The exact value depends on the current, the cross section, and the material.

The speed at which a signal can propagate in copper is about 2/3 of the speed of light in a vacuum - so, about 200,000 km/second. It is this speed that makes your light react quickly when you activate a switch.

The smallest spy plane in existence is the palm-sized Black Widow, developed by Aerovironment of Monrovia, California, USA, for possible reconnaissance use by ground combat troops. It has a wingspan of 15.24 cm. (6 in.), weighs just 80 g. (2.8 oz.) and carries a tiny color video camera weighing 2 g. (0.07 oz.).

Corporate photography is the use of photography by commercial enterprises for any purpose, not just advertising. For instance companies often hire photographers to shoot photos of their employees and facilities for internal reports (quarterly newsletters, annual reports, etc...), as well as for Public Relations, recruiting, and many other purposes. In fact, advertising photography is often regarded as its own field separate from corporate photography. Contrary to popular usage, the term "corporate photography" does not refer to any particular style. In fact, various styles and methods of photography such as documentary, contemporary portraiture, architectural, etc... can be used for the purposes of corporate photography.

Math is used extensively in photography to determine various aspects related to the image and its quality. Here are some of the ways math is used in photography:

Exposure: The process of capturing an image involves exposing the camera sensor or film to light. The three elements that control the amount of light entering the camera are aperture, shutter speed, and ISO. These elements are all measured in mathematical values, and a basic understanding of math is needed to determine the correct exposure settings for a particular scene.

Focal Length: The distance between the lens and the camera sensor or film is called the focal length. A longer focal length results in a narrower field of view and a closer image. Calculating the focal length is based on mathematical formulas.

Depth of Field: Depth of field is the area in focus in the image. It is determined by the aperture, focal length, and distance from the focal point. Understanding the math behind depth of field can help photographers achieve the desired effect of having a sharp or blurred background.

Composition: Composition in photography refers to the arrangement of elements in the image. The rule of thirds is a compositional guideline that suggests dividing the image into thirds both horizontally and vertically, and placing important elements along these lines or their intersections. This guideline is based on mathematical principles and is believed to create a more balanced and visually pleasing composition.

In summary, math plays a crucial role in many aspects of photography, including exposure, focal length, depth of field, and composition. Try this recommendation from an expert in photography: ₕₜₜₚₛ://www.dᵢgᵢₛₜₒᵣₑ₂₄.cₒₘ/ᵣₑdᵢᵣ/₄₆₅₇₄₆/ₛₑₜᵢ₀₄/

I can provide you with the general steps to set exposure on your camera.

1. Choose your camera's mode: Depending on your camera, it may have different modes such as Manual mode, Aperture Priority mode or Shutter Priority mode.

2. Adjust the ISO: ISO settings determine how sensitive your camera's sensor is to light. The higher the ISO, the more sensitive the camera will be to light. If you’re shooting in low light, you may need to increase the ISO.

3. Set the aperture: In aperture priority mode, you can choose the aperture and the camera will automatically set the shutter speed for the correct exposure. A wider aperture (lower f-number) will let in more light but will result in a shallower depth of field.

4. Set the shutter speed: In shutter priority mode, you choose the shutter speed and the camera will automatically set the aperture for the correct exposure. A slower shutter speed will result in more light but may cause motion blur if the subject is moving.

5. Metering: Your camera may have different metering modes such as evaluative, center-weighted or spot metering. This determines which part of the scene the camera uses to calculate the exposure.

6. Check the exposure: After setting your camera, take a test shot and check the exposure using the camera’s histogram or by manually checking the image. If the image is too dark, adjust the settings to let in more light, and if it’s too bright, reduce the amount of light.

• The Camera phone was invented in 1995 by Kodak engineer James Schueckler. Search for US patent 5666159. The patent discloses 2 possible configurations: one as a camera connected to a separate cell phone and one with both camera and cell phone integrated into a single hand-held device. The patent shows details: block diagrams, timing, and user operation and some possible extensions.

Retail refers to photography commissioned or purchased for personal use.

if you dont bielive in him,the others will prove he is real.for the REAL CLUE,bring a Camera recorder and when your camera goes static,it means slendy is nearby,1 one more thing,Just dont look back.

There aren't clear cut categories in SLR lenses. They range greatly in price depending on what features (such as Image Stabalisation) you want on the lens.
