What is photography and what is photography?
When trying to quantify what is photography, it’s important to first start with a photography definition. In layman’s terms, photography is quite simply the process of capturing light with a camera to create an image. This was done for the first time in 1826, when Joseph Nicéphore Niépce took a photo out of his window.
What is technical photography?
What can infrared photography reveal?
What is a rak photo?
What is polarized light photography?
What is UVF photography?
What are technical elements in photography?
There are seven elements of photography that break down each of the things a true artist should focus on, and they are: line, shape, form, texture, pattern, color and space. Each brings its own unique quality to a picture.
What is the technical quality of a photo?
Factors that affect quality include brightness and evenness of illumination, contrast, resolution, geometry, color fidelity and color discrimination of an observed image. Achieving the highest possible image quality relies not only on using the best available equipment, but also making correct photographic choices.
What does technical quality mean?
Technical quality refers to what is delivered whereas functional refers to how it was delivered and both of them develop customers' perceived service quality (Rauch et al., 2015; Tamwatin et al., 2015).
What makes a high quality photo?
Hi-res images are at least 300 pixels per inch (ppi). This resolution makes for good print quality, and is pretty much a requirement for anything that you want hard copies of, especially to represent your brand or other important printed materials.
What determines quality of a picture?
Image resolution is often given in PPI (pixels per inch). It means how many pixels are displayed per inch in the image. Photo resolution is a factor that determines image quality. However, the camera sensor, processor, and even the quality of the lens you are using also play a part.
What determine the quality of a digital photograph?
The resolution of a digital photo is expressed in terms of "megapixels" which is total number of pixels in the photo. So, a photo that is 2048 pixels x 1536 pixels in size, which is a total of 3,145,728 pixels would have a resolution of 3 megapixels.
What is a high quality digital photo?
Hi-res, or high resolution, refers to the density of the pixels that make up the photo. A high resolution digital photo has lots and lots of pixels, making it easy to see the details within the image even when it is enlarged digitally or in print.
What different light says about the object
The different layers that a painting is composed of reacts uniquely to different wavelengths of light. Below is an sketch explaining what specific technique is used for a certain layer.
Explanation for the different TP technics
Art examination starts with a high-quality photographic documentation in the standard visible range of the electromagnetic spectrum. Color camera calibration, exposure correction, white balance, sharpness. color checkers, resolution.
What is the most widely used photographic process?
The most widely used photographic process is the black-and-white negative–positive system ( Figure 1 ).
What is the camera used for?
In its simplest form, the camera is a light-tight container carrying a lens, a shutter, a device for recording the image in the correct plane, and a viewfinder to allow the camera to be aimed .
What is the function of a camera?
In its simplest form, the camera is a light-tight container carrying a lens, a shutter, a diaphragm, a device for holding (and changing) the film in the correct image plane, and a viewfinder to allow the camera to be aimed at the desired scene. The lens projects an inverted image of the scene in front ...
How many feet does a camera lens have to be to record?
Typically, a fixed shutter setting gives about 1/50 -second exposure; the lens is permanently set to record sharply all objects more than about five feet (1.5 metres) from the camera. Provision for a flash may be built in.
What is depth of field in photography?
What DoF is is the difference in focus from your subject matter, and all the background material in your photo. Having a very low f-stop number set will cause your background material to be very blurry, while having the subject in focus. You can see an example of this with this picture of a turbo:
What aperture is good for taking pictures?
The one thing that can be confusing about aperture is that a bigger number does not make the image brighter, but a smaller number does. An F-Stop of 1.8 is a very low number, and will let a significant amount of light into your camera, meaning you can take pictures in very low-light situations. A low f-stop has another effect besides just a brighter image though.
What does shutter speed do?
Shutter Speed (the Tv or Shutter Priority setting on your camera) is the camera setting which determines how long the shutter will remain open when you push the shutter button to take a picture. Whenever the shutter is open, your camera’s sensor is gathering every bit of light that is in front of your camera, and if the shutter remains open for a longer period, the more light that will come in making your picture brighter. The downside to this is that if there is any shake, or tiny movements of your camera because you’re not holding it in the exact same spot, the source of the light will be coming from different spots, which will cause a blurry image.
How do different camera settings work?
The simplest way to understand how all the different settings work is to remember this one thing: every setting will change only thing, how much light is let into the camera, or how bright or dark the image will come out. There’s 3 main settings that you’ll be changing, they all have their own pros and cons and side effects, and learning how to mesh them all together based on the look your going for will help you narrow down your vision into your photos.
What is the effect of ISO on a camera?
Unlike the Aperture setting, the lower the ISO number, the darker the resulting image, and the higher the number the brighter . The resulting side effect from making your ISO number higher is a “grainy” image. Sometimes a grainy image can be cool, but only if it’s grain that’s added in in a program after the picture is taken, ISO causes “digital grain” which is different, and never looks cool.
What is photography game?
Photography is an inner game. Everything about who we are is expressed in our photos. You can ask 100 photographers to photograph the same scene and they will all pick out different elements, they will all work on different parts of the scene and they will all end up with different images.
Is photography an exciting way to be creative?
Photography is such an exciting way to be creative, I hope I’ve given you some ideas on how to challenge yourself to keep improving and growing as a photographer.
What is photography in the public domain?
In layman’s terms, photography is quite simply the process of capturing light with a camera to create an image.
Why is photography so complex?
That’s because photography is incredibly complex. It has many facets and types. There are technical aspects to photography as well as creative ones. The manner in which photography is used is even different, often from one person to the next. Moreover, there is an unlimited variety in the quality of photos.
What are the major advancements in photography?
From there, many other advancements were made in photography, including the development of 35mm cameras, instant film, digital photography, and the development of mobile photography. These and other photography milestones are detailed in depth in our examination of 14 turning points in the history of photography.
What is Kodak 70mm film?
This Eastman Kodak film was transparent cellulose that came in 70mm format. The rolls were then cut down the middle (by Thomas Edison, no less) to create what became the standard film size of 35mm. These small, easy-to-use rolls of film revolutionized photography and made it something anyone could pursue.
How many camera settings are there in photography?
For all you beginner photographers out there, photography is built on light, and as such, you have to learn how to control it. There are three camera settings that comprise the very basics of photography, and that each independently control light in a different way.
What does ISO mean in photography?
ISO controls the sensitivity of the camera's sensor to light. ISO is measured in stops like 100, 200, 400, 800, and so on. As the ISO value increases, the sensor becomes more sensitive to light. Additionally, the higher the ISO, the more digital noise there will be in the image.
When was the daguerreotype invented?
The Daguerreotype. Invented in 1829 by Louis Daguerre, a French Painter, the Daguerreotype process was based off Daguerre's work with Niépce. Daguerre's process of photography shortened the very long exposure required for a heliograph and resulted in images that were much clearer.
What is the artistic part of photography?
The artistic part includes an understanding of light because the only thing that film or digital sensors record is light levels, so it’s the only real tool for photography. It includes the understanding of composition: the relationship of lines and forms and colours in the image area. And it includes the imagination to transform ...
How are technical and artistic aspects connected?
It turns out that the technical and the artistic aspects are connected, with each drawing upon and supporting the other. As a quick example, suppose a photograph was made with exquisite lighting (either indoors, with controlled lighting, or outdoors with ambient lighting), with a magnificent relationship between the forms in the image, and an excellent imagination that transforms the scene into an insightful photographic image. But the printing of the image is awful — perhaps it’s too high or low in contrast, or too light or dark, or the manipulation used to achieve the final print is too obvious. Then all the artistic values are lost.
Is a tack sharp image a fuzzy concept?
Yet I often hear people praising how sharp it is. But it’s a fuzzy concept — or no concept at all. It’s technically perfect, but meaningless.
What is technical photography?

Different lighting sources and filters are used to acquire a selection of technical images, each one providing different information regarding the object under examination.
What can infrared photography reveal?
Infrared photography can reveal underdrawing, changes and even faded signs, as in this example. Some pigments become transparent already in the near infrared range that a modified digital camera can detect. The dark pigments in this example disappear in the IR image revealing the white support and the sign which was written with a carbon-containing paint which remains opaque in IR.
What is a rak photo?
Raking light photography ( RAK) is a very simple method. Nevertheless, it allows to reveal and to document numerous information. A standard VIS photo is intended to reproduce the look of the artwork as seen in museum lighting, with soft and diffused light. RAK photo clearly shows how the paint was laid (brushwork), texture and building up of figures and details.
What is polarized light photography?
Polarized light photography (PL) and Raking light photography (RAK) are very helpful photographic methods widely used by fine arts photographers and they also belong to the visible range of the spectrum.
What is UVF photography?
Ultraviolet Fluorescence photography ( UVF) is probably the most diffused technical method for art examination since it can be successfully applied on practically every art or archaeology object category. In a painting, UVF photo reveals retouchings as dark spots while the aged original materials exhibit light emission with different colors.
