An A-Z of Photography Jargon Explained - Simply

Photography Jargon Explained Simply #photo #tips
If you've ever been baffled by all the jargon that's used in photography (aperture? f-stops? what on earth is ISO?!) then I hope this post will go some way to explain all the photography terms that you've ever wondered about (but never thought to ask). As with all my photo tips posts I try to explain everything as simply as possible. I write them assuming you don't know the meaning of any jargon at all, so it's layman's terms all the way.

I've picked what I think are the most common terms that are used which are essential to know more about (and understand) if you wish to improve your photography skills.

If you have any questions at all please don't hesitate to leave a comment or tweet me - and if you've found this jargon-busting post useful please do let me know and feel free to share it on Twitter or Facebook!


Aperture

In optics, an aperture is "a hole or an opening through which light travels". So in a camera, the aperture is the hole in the lens that lets light through, and this can vary from a very small hole to a very large hole.

The aperture of a lens works very much like your eyes: your pupils get bigger and smaller to let in more or less light according to how much light there is. A lens does exactly the same thing.

The size of the hole (the aperture) depends on the amount of light in the scene you're photographing and whether you've set it manually (to set the aperture yourself) or whether you have it on auto (where the camera will determine what aperture to set).

See f-stop (below) for how aperture is measured.


Bokeh

Bokeh is the term used to describe the out-of-focus parts of a photograph which have blurred to create a pleasing blurry "points of light" effect (see below). It's often used to describe a blurry background effect, but strictly it's for points of light. Think fairy lights gone out of focus.

Bokeh (blurry points of light) example
To find out how to create this effect, see my post on How to Achieve Photographic Bokeh.

The pronunciation: there is debate over how bokeh is pronounced. The most widely accepted pronunciation is "bo-ke" ("ke" like the first part of "Kenneth"), with no emphasis on either syllable.

This video explains how to pronounce bokeh (though he insists there is only one way to say it). Note: It definitely doesn't rhyme with "okay".


Bridge camera

A bridge camera is a camera that's in between point-and-shoot and DSLR cameras - they "bridge the gap" between the two. They look much like a DSLR, with a lens that sticks out at the front and a chunky body, but unlike DSLRs the lens is fixed. (Some bridge cameras do have retractable lenses, however.)

The advantage of a bridge camera over a point-and-shoot is that you have far more control over your settings: depending on the model you can adjust, for example, the aperture (see above), shutter speed (see below), the ISO (see below), thus allowing you greater creativity. Because the lenses are not interchangeable, they are generally cheaper than DSLRs.


Depth of field

Basically, depth of field is how much of the image (depth-wise) is in focus. More specifically, it is the distance between the nearest and farthest point that is deemed to be in focus, or sharp. See the image below:

Photographic depth of field examples: small (left), large (right)
Left: small depth of field, Right: large depth of field.


DSLR

DSLR stands for Digital Single Lens Reflex [camera]. Digital means it produces digital images that are stored on a memory card in the camera. Single Lens Reflex means the viewfinder of the camera gives you the same view that the lens sees, because you are actually looking through the lens via mirrors and prisms. An SLR camera is exactly the same except that it uses film to produce negatives, not a digital memory card.

Point-and-shoot, or compact, cameras are not SLR cameras as they don't have interchangeable lenses that stick out on the front of the camera (where the mirrors and prisms are). You have a lot less control over the settings because you can't set aperture (see above), ISO (see below), and so on to your specific preference that you can with SLR cameras.


Exposure

The exposure of a photograph is how much light is let into the image. It's easier to think of film photography because when you use film, the exposure is how much light is hitting the film. It's determined by the aperture (see above), the shutter speed (see below) and how much ambient light there is in the scene.

If an image is underexposed then not enough light was let into the image/hitting the film - it will appear too dark.
If it's overexposed then too much light was let into the image/hitting the film - it will appear too light/bright.

Note: in photography there is also "an" exposure, which refers to the action of the shutter (see below) opening and closing in the camera in order to take the photograph.


f-Stops

You now know what aperture is (the size of the opening in a lens, see above). Aperture is measured in f-stops (f stands for focal) - they are sometimes referred to as the f-number.

The image below shows some of the f-stops a lens has (there are more in between, e.g. f1.8, f3.5) and how it affects depth of field. Not all lenses have all the f-stops (see lens speed below).

Photography aperture explained: f-stops and depth of field
The larger the aperture, the smaller the f-stop number (confusing, I know). Remember:

A SMALL NUMBER, e.g. f1.4 = a BIG HOLE and a SMALL DEPTH OF FIELD.
A LARGE NUMBER, e.g. f16 = a SMALL HOLE and a LARGE DEPTH OF FIELD.

Therefore, to get bokeh or blurry backgrounds, you need a large aperture like f1.4 or f1.8 to create a small depth of field.

For a fun, quick lesson that demonstrates how aperture works with the human eye, see this post. All you need is your hands, your eyes and a space of about 6 feet (2m) or more in front of you. Prepare to be amazed...!


Golden hour

In photography, the hour before sunset and the hour after sunrise are both known as the golden hour. It produces a warm, soft glow and because the sunlight is hitting the subject horizontally rather than vertically it doesn't create any harsh shadows (under the nose, for example), so it's incredibly flattering.

Golden hour - sunset
You can also shoot with the setting/rising sun behind the subject to create an even softer effect.


ISO

This is easier to think about in terms of photographic film. (You can of course still buy film to use in non-digital cameras, but for this post I'm assuming everyone is using digital.)

The ISO of film is how sensitive it is to the light entering the camera. You can buy high and low ISO film (and many in between). In digital cameras the ISO is how sensitively the camera reacts and records the light to create an image.

A lower ISO (100) will be less sensitive to light so you need to have a lot of light entering the lens, e.g. a bright sunny day.
A higher ISO (800+) will be more sensitive to light so you don't need to have as much light entering the lens, e.g. a low-lit interior with little daylight coming in.

Some modern DSLR cameras have an ISO sensitivity range from ISO 100 to an amazingly high ISO 6400 (I've rarely had to go above ISO 800 ever).

Note that the higher [number] ISO, the more grainy the image will be. However, DSLRs made today produce images of incredible quality, so e.g. ISO 800 on a digital camera is nothing like as grainy as photographic film of ISO 800.


Lens speed

The speed of a lens is determined by the maximum aperture of the lens. If its maximum aperture is f4 it's considered a slow lens. If its maximum aperture is f1.4 it's considered a fast lens.

A fast lens with a large maximum aperture (f1.4) will let in more light, thereby allowing you to use a lower ISO and shoot in lower light levels, giving you less grain and sharper images. As light is everything in photography, fast lenses cost more money. Read my full explanation of a fast standard lens in my 6 Camera Equipment Essentials post.


Shutter/shutter speed

The shutter is effectively a little trap door behind the lens that opens and closes to let in light in order to convert it into an image.

Shutter speed is how long the shutter is open. It's measured in fractions of a second (though you can create exposures in whole seconds in very low light conditions, e.g. to photograph the night sky).

Slow shutter speeds will be effected by camera shake unless a tripod and remote is used. A shutter speed of 1/60 (one sixtieth of a second) is about the slowest speed that the average person can take a photo without being affected too much by camera shake, so the faster the better if you're not using a tripod.

Photography: Slow shutter speed example
Slower shutter speeds can be used effectively to record movement in the object if a tripod and remote is used to keep the camera steady. The image above was taken using a shutter speed of 1/2 (half a second) and I kept my head as still as I could and swayed gently to move the dress only.


White balance

White balance is what a digital camera uses to remove unrealistic colour casts when taking a photograph. You often find that photographs taken under fluorescent lights, for example, have a strange blue colour cast to them - this can be corrected by adjusting the white balance settings on the camera.

If the white balance has been adjusted accordingly, objects that appear white in person will look white in the photograph.

Black and White Winter Layers - Smart White Coat and Fedora

Winter white coat, fedora and riding boots
So my infatuation with winter neutrals continues with this outfit of black and white layers. I wore this last week in London and it was so cold I didn't actually overheat on several very crowded tube rides - being a comfortable temperature on the Underground at any time (summer or winter) is a bit of a miracle.

I've shown the outfit both with and without the oversized blanket scarf (sadly sold out but I do love this one by River Island) as I loved it both ways. It was everything I wanted from a winter outfit: comfy, warm and smart. A white coat may not be the most practical choice for travelling on public transport, but I only got a couple of smudges on one sleeve (they came out) so I think I did pretty well!

This encompasses so many pieces I love wearing in the winter right now: riding boots, a smart coat, white roll neck, a black fedora. What are your favourite pieces? And how practical are they...?! Do share in the comments!

Winter Neutrals | Oversized Feather Cossack Hat and Check Coat

Winter neutrals: Oversized feather cossack hat and check coat
I actually got this gorgeous feather Cossack hat last Christmas (2013 I mean) but the months following were too mild to wear it - you need a really cold day to wear this beauty. So it finally got its first outing this month when the temperature dropped, and =ohhhhhh= how it keeps your head warm. With a checked coat bought a few winters ago (that I'd almost forgotten I had), a thick roll neck sweater, coloured jeans and ankle boots I had a toasty warm 'winter neutrals' outfit. With a bit of red thrown in.

You need a certain amount of confidence to wear a hat like this - I'm a big fan of hats and usually happier with a hat than without - but this one is so huge it takes a lot of bottle to go round doing the whole Julie-Christie-in-Dr-Zhivago thing. Mind you, I have a little head so it's nice to have it beefed up for a change...!

Are you a fan of hats? Do you feel you need a lot of confidence to wear them - and would you wear one this huge?! Let me know!

Winter neutrals: Oversized feather cossack hat and check coat

Winter neutrals: Brown and black check coat
Hat: Debenhams, Coat: Debenhams (old - I love this one), Sweater: Asos, Jeans: Asos, Boots: c/o La Redoute, Bracelet: Asos, Nails: Nails Inc Bluebell (limited edition)
