Important concepts and terms in photography

Important concepts and terms in photography

Sometimes it may feel like we who work with photography speak our own language when we communicate with each other. There are a lot of technical terms that you should try to keep track of, which can make it difficult and keep up with the discussion among photographers. That is why we have put together a long list where we explain some classic terms and concepts in photography that we hope can help you keep up with the conversation.

The Golden Ratio Rule - means that you have what you photograph on a third of the image to make the image look better. Which third you choose depends on what you are photographing and what is most interesting in the picture. If you photograph, for example, a sunset, you can use the upper or lower intersection. Is it the foreground that is most interesting or is it a spectacular colorful sky that is important?

ISO - I international < / span> S tandardization O organization / International Organization for Standardization

We raise and lower the ISO on our camera depending on how much light we have access to where we shoot. Sometimes you can also raise the ISO so that the flash you use does not run out of battery so quickly.

High ISO allows the images to be a bit grainier, a bit like the movie time. But it all depends on how high you go, today our cameras are capable of very high ISO without providing super grainy (pixelated) images.

Aperture - The aperture we use when shooting depends on how much of the background you want to have visible in the image. Small figure, ie large aperture gives a blurred background to what we are photographing.

What aperture numbers you use depends on what is important about the image. If you are looking for an image where everything is tack sharp, use a high number (small aperture) when shooting.

Shutter Speed ​​ - Determines whether you freeze a special moment or not, or give it motion blurr.

Exposure - When you press the shutter button, the film or image sensor on the camera is exposed to light, and this is called exposure.

RAW format - a digital image format, just like for example jpg and png.

When you save the image in RAW, it is a saved raw data. This means that, unlike jpg, the image is not complete at the moment it is taken but requires some editing, its a negative like in the old days when you used film. For example, you may need to adjust white balance, temperature and contrast afterwards, which means you can concentrate on image composition and sharpness when shooting. We will solely photograph in the RAW format in order to be able to edit the images well afterwards.

In sports photography, shooting in jpg may be advantageous because the camera buffer jpg files faster than it does with large RAW files.

Wide-angle lens - a type of lens that is often used for photography in reporting, architecture, or when shooting landscape images. The wide angles have short focal lengths which means a large viewing angle.

Telephoto Lenses - works much like a binoculars. They have a large focal length and are good at enlarging distant motifs. Short telephoto lenses are usually used for portrait photography and sports and nature photographers often use longer telephoto lenses.

Vignetting - means the corners of the image will be dark. Sometimes, as a photographer, you want to get the effect that vignetting does and make the image more exciting and / or dramatic It also can help guide the viewer towards the center of your image.

Macro - abbreviated word for macro photo . A general term for close-up photos, where the subject is imaged in near-natural size and then greatly enlarged when the subject comes out as a finished paper copy.

Contrast - the difference in brightness between the dark and light areas of the image. Increasing the contrast in the image you have taken often results in the colors being perceived as stronger and the white in the image becoming whiter and the blacks becoming more black.

EXIF ​​information - Ex changeable I stomach F ile. A format where you store information about what settings you had on your camera when you took the picture. Almost all cameras store all settings and this information can be viewed in various image processing programs. This is where you write your copyright text onto your image.

AF - Abbreviation of A automatic F oscillation and means the sharpness is set automatically.

We almost always use AF when shooting. When filming, we very rarely use AF we then focus ourselves. It depends on the effect you are looking for on the movie.

Ambient light - the natural light that exists without adding light from flashes or lights.

Cropping - a snippet of the subject and the image. You cut away excess parts of the image in order to adapt it to a particular dimension or often to emphasize what is important in the image.

Aspect Ratio - (aspect ratio) describes the image's proportions = width x height.

Mixed light - just as it sounds it allows different types of light to be used simultaneously when shooting. For example, shooting with a flash + a ceiling lamp.

Flash Sequence Time - the time it takes for a flash unit to recharge after shooting it off. If it is too slow you sometime miss your picture.

You can buy new, special flashes that are faster. For example, the Profoto A1 flashes, that we use.

Flash hot shoe - The camera mount where you attach the flash or other camera accessories. Usually onto of your camera.

Bulb mode - a shutter speed option that can be manually selected on your camera. Your shutter speed is the length you choose. When shooting waterfalls, I like to control the shutter speed myself and then I use bulb mode.

Filters - something you mount on the lens to block specific colors, signals, reflexes etc.

Fish-eye - a type of lens with extremely short focal length. The lens provides round images and up to 220 degree viewing angles.

Color Match - when the color of the image is out of balance and there is too much of a certain type of color. For example, if the image is too red, it is said to have a red stick.

Color Temperature - the measure of the color composition of the light and measured in degrees Kelvin. Red light has a low color temperature and blue light is high.

Underexposed - when the image is too dark. There is too little light in the camera and it may be because either the shutter speed is too short or the aperture is too small.

Pan - you rotate the camera with a moving object the camera moves in the same direction and speed as the object. If you follow a moving subject while exposing the image, the subject becomes sharp and the background becomes blurred, depending on how long shutter speed you have. This is often used in rally photography.

Backlight - one or more light sources that shine directly on the lens, such as the sun. Objects that are then in front of the light source usually appear only as a silhouette.

Lens hood - Attaches to the front of the lens and screens of light coming directly into the lens. We have lens hoods on almost all our lenses.

Do you have any other photography terms you don't know the meaning of and want me to clarify, just let me know.
