The Ultimate Guide to Essential Photography Terms & Definitions

Some photography terms can make you scratch your head. You might even wish for a Photography to English dictionary. It also affects the depth of field. The f-number or f-stop is the ratio of the diameter of the hole of the aperture and the focal length.

As the number decreases, the aperture physically gets wider. More light passes and the depth of field gets shallower. Generally, lower f-numbers mean better low-light capacity. This is why lenses with lower f-numbers are more expensive. Lenses have a point where light rays converge and we call it the focal point. The distance between the principal plane of a lens and the focal point is the focal length.

This number is expressed in mm and written on the outside of the lens. A 35mm lens has a distance of 3. It determines the angle of view and magnification in photography. This is one of the main parameters which marks and groups the lenses. This number is magnified when using a cropped sensor. There are two different kinds of lenses. A zoom and a prime lens. A zoom lens is a variable-length lens, which means that you can change the focal length of it.

This allows you to change perspective easily. Although these are more versatile, they often have limited sharpness due to needing more mechanisms inside the lens. As we looked at above, you have the choice of two different lenses.

A prime lens is a fixed lens unable to zoom in or out, forcing you to zoom with your feet. Different fields of photography require different prime lenses. Are you looking to photograph insects, flowers, or something more abstract? Then this is one of the most important camera terms to know. Macro lenses are telephoto lenses with a really close near point.

The near point is the closest point to the lens where the subject is still sharp. A macro lens can produce a magnification ratio of or even higher. The magnification ratio refers to the size of the subject appearing on the sensor of the camera, and the size of it in real life. This lets you take breathtaking photos of really small creatures and objects too.

The diagonal of a 35mm film or a full-frame sensor is approximately 45mm. A wide-angle lens can have for example 24mm focal length. So we can clearly see, that the focal length is shorter than the diagonal. So, they have a wider view than a standard lens and our vision.

A fisheye lens produces images with strong barrel distortion. This is due to the angle of view being wider than the sensor or film format, squeezing the edges to fit. They go from 4. A standard lens has a focal length approximately equal to the diagonal of the image the negative. It has a field of view similar to our non-peripheral vision. Telephoto lenses are lenses with focal lengths longer than the diagonal size of the image they take. This results in a narrow field of view.

Tilt-shift lenses give you extensive perspective and focal control. They are generally expensive. The position and angle of some lens elements can be independently changed in such lenses. This allows them to be moved and tilted relative to the sensor. The effect is possible to be created with Photoshop as well, albeit less precisely. Such lenses have a built-in gyroscope and moving lens element s.

In stabilised camera bodies, the sensor moves according to a gyroscope in the body. This cuts down motion blur by compensating on pan and tilt movements. This technology makes it easier to take photos while holding your camera in your hands. Also, it allows you to take photos with longer shutter speed. Thanks to the built-in image stabilisation, you can be more mobile. This is the most common type of element in lens making.

The curve of a spherical lens is the same across its entire surface. This is what focuses the field of view onto the film plane. It usually creates spherical or optical distortions. It is not always a problem. If you are planning to buy new lenses, we recommend paying attention to this photography term. Sometimes you definitely need your images to be sharp.

A lens hood blocks light coming from the sides from causing unwanted reflections and flares. A lens hood can also play a protective role. Also, it can stop dust and camera lens fungus from getting inside your lens. SLRs use a mirror and a prism to reflect the light coming into the camera. This allows photographers to see through their viewfinder and see exactly what they are going to capture. The mirror flips up when the shutter is open to allow light to expose the film. They work with the same mechanical system as SRLs, but instead of using a film, they capture the image digitally and store it on a memory card.

With the top one, you can focus and compose the scene. This is part of the viewfinder system. The viewfinder uses a mirror, a matte focusing screen, and a hood. The bottom lens is solely used to take the photograph. These two are connected, so if an image appears sharp in the viewfinder, it is going to be sharp on the film too. Medium format cameras use the roll film. Digital medium format cameras have a digital sensor that mimics that size. The exact film ratio for medium format is different for each brand or camera type.

They all use the same film, but the amount of frames depends on the camera. Medium format cameras are usually modular. This means you can interchange lenses, backs, viewfinders, grips, and more. Technically, Polaroid cameras are also medium-format. You can capture greater details with a large format camera because it reaches the biggest possible resolution in analog photography. These are great for architectural photography due to the manipulation of film and focus planes.

Also perfect for environmental portraits, conceptual artworks, and studio photographs. Mirrorless camera systems are a fairly recent development in digital photography. By removing the mirror, cameras can be faster, lighter, and quieter. This photography term means that you can no longer look through the lens optically when composing.

The term generally refers to more advanced devices, MILCs. This abbreviation means Mirrorless Interchangeable Lens Camera. A point-and-shoot camera is also known as a compact camera. They are small enough to fit in your pocket. You can create photographs and videos you can move around in. The complementary metal-oxide-semiconductor is a type of imaging sensor. They were once considered an inferior technology. Today, they have been vastly improved and are the more common sensor type of the two.

The readout is thus time and energy-consuming. CCD cameras have to use the whole surface of their sensors. It offers high image quality and resolution and can handle low-lit scenes with less noise than smaller formats. For more information, see our Full Frame vs Crop Sensor article. The Advanced Photo System type C is an image sensor format.

The complete dictionary of Photography

Nov 12, Photography 0 comments. I remember very well from my own learning process that learning photography can feel a little overwhelming. The words only the insiders know. What does that even mean? The first step in learning photography is to understand the words photographers speak. Are you looking for a step-by-step plan to buying your first camera?

101 Photography Terms You NEED to Know

They can be found by selecting Effects on the cameras mode dial, and scrolling through the various effects via the command dial. The illumination produced from a gas-discharge lamp or tube is called fluorescent light. Electricity to the lamp stimulates the mercury vapor within the lamp creating the emission of electromagnetic radiation which produces the fluorescence.

Some photography terms can make you scratch your head. You might even wish for a Photography to English dictionary. It also affects the depth of field. The f-number or f-stop is the ratio of the diameter of the hole of the aperture and the focal length. As the number decreases, the aperture physically gets wider.

Basic photography concepts: aperture, shutter speed, ISO speed, exposure

After all, those great how-to guides and classes to improve image quality or depth of field are full of new terms and concepts. While there are hundreds of terms associated with photography, beginners should add these 25 terms to their vocabulary to get a good start on mastering the basics. This is the first common photography term you should learn. Think of the lens as a window—large windows or wide angles let in more light, while small windows let in less light. A wide open aperture will let more light into the image for a brighter photo, while a smaller aperture lets in less light. Aperture also affects how much of the image is in focus—wide apertures result in that creamy, unfocused background while narrow apertures keep more of the image sharp.

Learning a new skill can be overwhelming. You try to research your topic, but you find all of these words that everyone else seems to know but you. This is especially true in the world of photography. There are so many technical terms related to photography it can make your head spin. So I am going to break these terms down for you so that you can move on to applying them in your photography. Know The Lingo.

Сьюзан… Сьюзан… И в этот момент она все поняла. Дрожащей рукой она дотянулась до панели и набрала шифр.

Энсей Танкадо отдал кольцо, надеясь обнародовать ключ. И теперь - во что просто не верится - какой-то ни о чем не подозревающий канадский турист держит в своих руках ключ к самому мощному шифровальному алгоритму в истории. Сьюзан набрала полные легкие воздуха и задала неизбежный вопрос: - И где же теперь этот канадец. Стратмор нахмурился: - В этом вся проблема. - Офицер полиции этого не знает.

 Я ищу одного человека. - Знать ничего не знаю. - Не знаю, о ком вы говорите, - поправил его Беккер, подзывая проходившую мимо официантку.

 Плохой совет, мистер Беккер, - огрызнулся Джабба.  - Нужно сразу быть точным. У шифров-убийц обычно есть функция злопамятства - чтобы не допустить использования метода проб и ошибок. Некорректный ввод только ускорит процесс разрушения. Два некорректных ввода - и шифр навсегда захлопнется от нас на замок.

Беккер успел заметить лишь очки в железной оправе. Мужчина поднес к носу платок. Беккер вежливо улыбнулся и вышел на улицу - в душную севильскую ночь. ГЛАВА 42 Вернувшись в комнату, Сьюзан, не находя себе места, нервно ходила из угла в угол, терзаясь мыслью о том, что так и не выбрала момент, чтобы разоблачить Хейла.
