Photographic Jargon


Terms used in photography can often confuse a photographer, especially a beginner. Here is a list of photographic jargon, with as-simple-as-possible explanations.

APS-C: Describes a imaging sensor size or a camera using this size of sensor. APS-C stands for Advance Photo System, type C. Sensor size 15.7 x 23.7mm approximately. Varies slightly between manufacturers

Aperture: Set of metal blades that control the amount of light entering a lens (same as Diaphragm)

AVCHD: Advanced Video Coding High Definition. A format for digital recording and playback

AF Sensor: A sensor used in achieving autofocus

Buffer: Temporary storage of data before the images are written to the memory card

Bridge camera: Describes a camera that fits between a compact and a D-SLR. Also known as Prosumer camera

Ballhead: (Used on a tripod). Performs similar functions as a pan and tilt head but uses a central ball as a pivot to allow for camera movements

Battery Grip: A device that attaches to the base of a D-SLR. The battery grip, not only provides better grip for vertical shooting, but uses extra batteries to supply power to the camera when the camera battery dies down. In some cases, it helps to increase the frames-per-second firing rate

Burst mode: A camera mode that allows continuous firing

Barrel distortion: The outward bulging of straight lines in the center of the frame due to lens imperfection

Bit: Refers to a binary digit – the smallest unit of computer data, either 0 or 1

Bit depth: A measure of the number of possible colors/tones in an image. Our images are basically formed using the three primary colors (also known as channels), red, green and blue. JPEG files are 8-bits per channel (which is the same thing as 24-bit. When we say 24- bit, we should not say “per channel”). Raw files can be 12-bits per channel or 14-bits per channel that is 36-bit or 42-bit respectively

Bracketing: A method of taking three or more shots in succession (using different exposures), with a hope that at least one of them will be accurate. We also bracket when shooting for HDR imaging. Bracketing could also be for White Balance and ISO

CCD/CMOS: Types of imaging sensors. CCD stands for Charged Coupled Device. CMOS stands for Complementary Metal-Oxide Semiconductor

Compact camera: Describes a small, point-and-shoot type of camera

Center-weighted meter: One of the in-built exposure meter that places greater emphasizes on the central area of the frame. The user generally has the choice of selecting the area (8, 12, 20mm circle at the center)

Circular Polariser (CPL): A polarizing filter designed to be used with digital cameras (as well as certain film cameras). A CPL prevents secondary polarization of light at the reflex mirror, thereby preventing exposure/focussing error.

Contrast-detection AF: A system of autofocussing wherein the camera uses contrast as the basis of evaluating correct focus

Chromatic Aberration: The inability of all the three primary colors (Red, Green, Blue) to focus on the same plane. This manifests itself in the form of color fringing at the edges and is most noticeable against high-contrast elements in the picture

Clipping: Overexposing of highlights. Underexposing of shadows.

Crop factor: A factor by which the focal length of a lens needs to be multiplied to get the equivalent focal length of a full frame 35mm sensor

Close-up lens/filter: A magnifying glass that is attached to the front of a lens to make the lens focus closer. The magnifications are described by the term ‘dioptre’. Eg. +1, +2, +3 etc.

CMYK: Cyan, Magenta, Yellow, Black. These are the colors used in books/ magazines printing

Color temperature: A measure of the color of light.

D-SLR: Digital Single Lens Reflex camera. An interchangeable lens camera that uses a reflex mirror for viewing

Diaphragm: Set of metal blades that control the amount of light entering a lens (same as Aperture)

Depth-of-field: The zone of sharpness in a photo.

DOF Preview Button: A button on the camera that allows you to visually check the depth-of-field.

Dynamic Range: The range of brightness that can be captured by a film or digital imaging sensor. This range is much lower than the dynamic range of our eyes

Digital zoom: In-camera electronic enlargement of the central area of a frame. Use of digital zoom should be avoided if high image quality is required. The same effect can be achieved during post-processing, by cropping an area and enlarging it

DPI: Dots per Inch. A measure of print Resolution

Diffuser: (1) A camera filter that softens an image (generally used with portraits). (2) Any material that softens the light from a ‘hard light source’ like the sun or a flashgun. Placed between the light source and the subject

Exposure meter: A light-meter that recommends the aperture and shutter speed for a given lighting condition. An exposure meter can be built into the camera or can be an external hand-held variety. To use any light meter, you first need to set the ISO sensitivity.

EVF: Short form of Electronic View Finder

Evaluative meter: One of the in-built exposure meter that divides the frame into various segments and based on thousands of pre-set exposures built into the camera’s memory, selects a suitable exposure depending on the lighting conditions and the set ISO sensitivity. Also known as Segmented/ Matrix meter

Frame rate: A measure of how many frames a camera can fire in one second

Flare: Image degrading, unwanted reflection of light within the lens

Full-frame: Denotes a camera/imaging sensor that is the same size as a 35mm film (24 x 36mm)

Focal plane: Describes the location of the film/imaging sensor within the camera

Focal plane shutter: A type of shutter used in SLRs/D-SLRs. This shutter is placed in front of the film/sensor.

Focal length: In a simple convex lens (a magnifying glass for example) and with light coming from infinity – the distance between the vertical center of the lens and the point where the light rays meet. Focal length tells us how much of the scene will be covered by the lens and what the magnification will be

Firmware: A downloadable software offered by the camera manufacturer. Generally used to upgrade/improve on a camera’s performance

Filter: (As applicable to a camera) a thin glass/plastic or gelatin placed in front of the lens to modify the color/quality/ quantity of light entering the lens

H.264: A standard for video Compression

Hardware: (In terms of computers) the physical elements that make up a computer system

HDR Imaging: High Dynamic Range Imaging. A technique of extending the dynamic range beyond the normal capacity of the imaging sensor. Three (or more) shots are taken from various areas of the scene (one from the shadows, one from the highlights and one from the midtones) and then combined in a computer program to create a picture with good detail in shadows as well as highlights. HDR technique is used when the lighting contrast is very high.

Histogram: A graph showing the distribution of tones in an image. The horizontal axis shows the gradation of tones from the darkest to the left, to the brightest at the right. The vertical axis shows how many pixels are there in any particular tone.

HSB: Hue, Saturation, Brightness. The standard color model for adjusting color in image editing programs

Intervalometer: A device that allows you to automatically take pictures at fixed intervals

IS: Image Stabilizer– a feature that eliminates/reduces the effect of handshake
ILCC: Interchangeable Lens Compact Camera. Describes a mirror-less digital camera with interchangeable lenses,

Incident Light Meter: A hand-held light meter that reads the amount of light incident to (falling on) the subject.

Interpolation: (As related to digital imaging) the act of introducing new elements (pixels) in an image

JPEG: Joint Photographic Experts Group – a compressed (data losing) file format

Jitter: Another way to describe the effects of hand-shake

Kelvin: A unit of measurement of color temperature based on absolute zero.

Lateral CA: Chromatic aberration in which all the colors are in focus in the same plane but are not placed along the optical axis

Longitudenal CA: Chromatic Aberration in which different colors do not focus at the same point

Leaf shutter: A type of shutter used in rangefinder cameras. Situated between the lens element

Linear Polariser (PL): A polarizing filter designed to be used with film cameras that do not use a ‘light-splitter’ in the exposure metering system

Live View: A camera feature that allows the LCD to be used as a viewfinder

LCD: Liquid Crystal Display – the display (monitor) at the rear of digital cameras

Macro lens: A special lens designed for life-size (1:1) photography

Memory card: The removable module within a digital camera that stores the images

Mid-tone: Average tone. Neither too dark or too light; an in-between tone

Noise: The digital equivalent of film grain. Noise is caused mainly due to underexposure.

Normal lens: A lens having a focal length equivalent to the diagonal of the given format

Optical Viewfinder: The normal viewing device in a camera, through which you view and frame a subject. It uses optical glass as opposed to Electronic Viewfinder that uses electronic circuitry to boost the information within

Pan and Tilt head: A camera support used along with a tripod, that allows the camera to be tilted (up/down) and panned sideways. It is different from a ‘ballhead’ in that it uses separate levers to control the pan and tilt

Perspective Control/Tilt-Shift lens: A special lens designed for correcting perspective distortion

Polariser: A filter that cuts off polarized light from entering the lens. This filter, when used correctly, has the ability to darken blue sky, cut reflections from water, glass, painted metal, wood, paper etc.

Phase-detection AF: A method of autofocussing that splits the image in two and compares the images for similar light intensity patterns

Perspective: The size relationship between the foreground, mid-ground and background objects in a photo.

Pin cushion distortion: The inward pulling of straight lines in the center of the frame due to lens imperfection.

Prosumer camera: Same as Bridge camera

Partial metering: Found mostly in Canon cameras, roughly 10-15% of the frame is measured in the center.

Pixel: The building block of any digital image; the smallest unit of any digital image. Short form of Picture Element

Inside Your Digital SLR

You don’t need to know anything about internal combustion to operate an automobile, and you really don’t need to understand digital technology to use a point-and-shoot digital camera, either. Both devices are so automated these days that there’s not a lot for the driver/shooter to do other than point the machinery in the right direction and press the gas pedal or shutter release. Even if you decide to use manual controls on a non dSLR, the only things you must understand are that this button makes the picture lighter or darker, that one helps freeze action, and this other button changes the way the camera focuses.

However, if you really want to master a digital SLR, you can benefit from understanding exactly how the camera’s components provide you with a much finer degree of control over your images than the typical point-and-shoot camera. Unlike digital snapshot photography, where it’s almost impossible to adjust depth-of-field, and usable ISO ratings range from ISO 100 to ISO 100 (just kidding!), the technology built into a dSLR does allow you to make a difference creatively and technically, if you know what you’re doing. And for the average serious photographer, that’s what taking pictures is all about.

With a digital SLR, it’s easy to use depth-of-field to manipulate your images, but you need to understand how digital cameras work with lenses and their apertures. The “graininess” of your pictures is under your control, too, but it depends heavily on things like the size of the sensor, the sensitivity setting you’re using, and what kind of noise reduction technology is built into your camera, and how you choose to apply it. If noise is bad, then noise reduction must be good, right? Yet, when you really delve into how your camera works, you’ll understand that noise reduction can rob your image of sharpness and detail. There are certain types of pictures in which less noise reduction is a better bet, even at a cost of a bit of “grain” in your image.

Or, would you like to take a picture in which a runner is frozen in time, but a streaky blur trails behind him like The Flash in comic books? You’d better understand the difference between front-sync and rear-sync shutter settings. Interested in using a super long telephoto lens without a tripod or switching to high shutter speeds? Step up and learn about image stabilization.

If you’re who I think you are, you don’t see understanding digital SLR technology as a daunting task, but as an interesting challenge. By the time someone is ready to use all the features of their digital dSLR, he or she is looking forward to taking greater control over every aspect of the picture-taking process.

The most comforting thing about digital SLR technology is that, for the most part, these cameras were designed by engineers who understand photography. Many of the point-and-shoot digital cameras I have used appear to have been designed by a techie who was creating cell phones or PDAs last week, and then moved over to digital cameras this week. They operate like computers rather than cameras, have features that nobody in their right mind actually needs, and often are completely unusable for the kinds of photography for which they are intended. For example, one alarming trend is towards pocket-sized digicams that have no optical viewfinder at all. For the majority of the latest models, it’s necessary to frame every picture using the back-panel LCD, which, unfortunately, washes out in bright sunlight, and almost forces you to hold the camera at arm’s length, guaranteeing that powerful image stabilization features are going to be required to nullify camera shake.

In contrast, digital SLRs are designed by people who understand your needs. They have, for example, large bright optical viewfinders that provide a reasonable display of approximatedepth-of-field, and which can be used under a variety of lighting and viewing conditions. The designers of dSLR models have been creating such cameras for many years and know from the feedback they receive what photographers want. So, learning dSLR technology will be rewarding for you, because you’ll come to understand exactly how to use features that have been designed to help you be a better and more creative photographer.


This chapter explains that technology, and will help you when you’re shopping for your next digital SLR. You’ll have a better understanding of the kinds of technology you should be looking for in your camera. If you already own a dSLR, after reading this chapter you’ll know how to put those features to work.

How to choose a tripod?

Here are some tips to help you choose a tripod -

1. Consider your application and choose as per the table
Application                       Type of Tripod
Travel / trekking              Light and compact, four leg sections, ball head
Wildlife / birds / sports   High load capacity to support heavy lenses, ball head or gimbal head
Macro / table top             Individually adjustable leg angles, tiltable center column, pan head

2. Your height: A tripod should allow you to work comfortably (that is the viewfinder of the camera must be at your eye level) without craning your neck too much or otherwise you will get neck cramps. Choose a tripod that reaches this height without extending the center column by more than 5 centi-meters.

3. Material of legs: If you can afford, legs made of carbon fiber are the best. If not, go for aluminium or its alloys.

4. Material of head: The head should be strong and made of metal. Just avoid plastic heads. Period. Plastic heads flex and are not good.

5. Load capacity and Stability: The legs and head you are going to buy should have sufficient load capacity to handle the heaviest equipment you have or plan to have (as explained). Plus a heavy head can cause instability due to top heaviness. To avoid this, the weight of the tripod legs must be 2.5 times that of the head (either ball or pan or gimbal).

6. Number of sections: It is best to choose tripods with three (telescoping) leg sections than those with four sections unless compactness is very important to you.

7. Leg locks: Go for twist locks if you are going support heavy loads. Otherwise flip locks are easier to use.

8. Quick Release: Do not buy a tripod head (or a tripod with a fixed head) without a QR adapter. If you already have one that does not have a QR adapter, you should get a QR clamp and plate(s) for it. The best and the most popular QR system is the Arca system. It is made by several manufacturers including Manfrotto.

9. Pay careful attention to the feet. The most versatile are the retractable or interchangeable type. If these are not available go for rubber feet.

10. When buying a tripod remember the old adage - “buy smart buy once, buy cheap buy twice”.

Tips and techniques while shooting a wedding

• Never complicate the lighting setup. You should try to keep the setup as simple as possible. It is advisable to carry portable lights and reflectors to get better shots. At the same time, in low lighting conditions, use the widest possible aperture or smallest possible f-value to get correct exposure. You can also boost your ISO value but it increases the noise in your images.

• The official shot is better done before the reception and not right after the wedding.

• Capture candid bridal moments especially when she’s getting dressed, her jewelry, her preparations to look her best. These shots can be caught from different vantage points with a prime lens and have no one feel that you are intruding. Shooting using a zoom or prime lens lets you capture some close shots from a distance and can be used to capture photographs of props such as wedding rings, bouquet, etc, as well.

• Create fine compositions instead of asking the subjects to move, and be aware of the lighting. If, in your viewfinder, the lighting looks harsh on your subjects’ faces, it may look even harsher in the final image.

• For getting a close-up image of the couple so the lighting is flat and even... It’s pretty easy to achieve this effect – all you need to do is place two soft boxes on either side of your subject at the same angle and at an equal distance. Set the power so it’s the same from each light. Try using a reflector under the face – your model should easily be able to hold this. This will bounce light up and onto the face

• In case of shots of friends and relatives, try taking images from the side lines while others have their photograph taken in front of them for a more natural looking shot.

• While capturing bride and groom portraits always aim to take natural images which convey love and happiness rather than endless posed images. For getting these types of wedding shots, shoot from a distance and from different angles to create interesting compositions.

• You can capture the wide angle of emotions of family, friends, and the groom during the ‘Vidaii’ by creating a panorama and also use two cameras to get those candid shots. You can also try a more creative approach to capture these shots using a fish-eye lens. Fish-eye lenses create some distinct images with radial blurs and curved looks which will distinguish your pictures from other photographers.

Daleka Vesela Pesma



Neko pesmu veselo pevuši,
Daleko je, daleko od mene.
Ja bih hteo da mu se pridružim,
Al’ ne daju grudi razbijene.
Uzaludno duša za njom žudi,
U grudima traži slične zvuke,
Zato što su i snagu i grudi
Iznurile nevolja i muke.
Odveć rano misli mi poleću
Ka snovima zemlje ideala.
Rano počeh da ropćem na sreću
I mislim šta prošlost mi je dala.
Rano dušom, strasnom, uzavrelom,
Tražih sebe u dane sumorne,
Pa ne mogu da pevam veselo,
Nemam snage, grudi su umorne.
Sergej Jesenjin

Cvili Harmoniko



Cvili, harmoniko. Puca glava…
Naviru zvuci vodoplavni.
Pij sa mnom, kučko šugava,
Pij sa mnom.
Obljubili te, opoganili-
Pripadaš ulici.
Zašto mokriš tim plavim pogledom?
Hoćeš po gubici?
U baštu bolje idi, strašilo,
Da plašiš vrane.
Do bola si me zajašila
Na sve strane.
Cvili, harmoniko. Cvili, stradijo.
Pij, mešino šuplja.
Ja bih onu sisatu radije-
Još je i gluplja.
Među ženama nisi mi prvina.
Ja sam vas mnogo…..
Ali sa takvom, kao ti, strvinom,
Prvi put smogoh.
Što bolnije, to bučnije,
Čas tu, čas tamo, bez traga.
Ja neću da se ubijem,
Idi do vraga.
Sa vašom psećom skućnicom
Vreme je da se oprostim.
Draga, ja plačem, mučim se,
Oprosti….Oprosti….
Sergej Jesenjin

Cveće Mi Veli, Zbogom Ostaj



Cveće mi veli – zbogom ostaj,
I krunice sve niže sleću:
Njeno lice i rodni kraj
Da nikad više videti neću.
No, šta ću, draga, i šta znam – 
Ja videh njih i zemlju ovu,
I samrtnički drhtaj sam
Primiću kao miloštu novu.
I zato što cilj, celoga veka, 
Postigoh, idući s osmehom zdravlja –
Ja i sad stalno tvrdim, bez jeka,
Da se na svetu sve ponavlja.
Nije li svejedno – drugi će doći, 
Tuga rastužiti otišlog ne sme.
A ostavljenoj u tihoj noći
Drugi će lepše pružiti pesme.
I prateći pesmu dušom žene, 
Draga uz drugog, usred slavlja,
Setiće se možda i mene,
Ko cveta koji se ne ponavlja.

Brdo Vidrak Valjevo

The usual suspects

Always on the lookout for interesting urban wildlife photo projects, Tomos Brangwyn discovered
one of the UK’s greatest nature spectacles happening in a supermarket car park

   With my chin pressed firmly to the ground, a flash in one hand and a fisheye lens in the other, this was one trip to the shops I was never going to forget. I was surrounded by a gang of mischievous iridescent starlings, whose lustrous feathers sparkled in the glow of the mid-morning winter sun.

   It was a special moment, undeniably. Starling numbers have declined dramatically in recent years and finding a remaining stronghold is not easy. Getting up close, in the hope of creating a strikingly personal image, was even harder.

   My father had told me stories of great murmurations taking place within sight of Buckingham Palace in the 1960s. A tale also persists of there once being enough birds to halt the movement of Big Ben when a large group landed upon one of its hands in 1949. But sadly, times have changed and none of my visits to either places yielded anything more than small and isolated flocks.

   Things became more promising when I was told of a supermarket car park where starlings arrive daily, tempted in from the countryside by the promise of crisps, sandwich leftovers and the odd piece of dropped fruit. They drink from puddles, pick through mud that has accumulated between the tread of car tires and perch upon windscreen mirrors. It sounded just too good an opportunity to miss.

   At 10am the following day, as if by clockwork, the first birds began to trickle in from the south. There were only a few starlings at first, but as the minutes went by, more and more gathered. The birds were hungry and were soon scurrying about, scanning the ground for breakfast scraps. One found a discarded apple core and raucous bickering among the group quickly followed.

   Not long after, danger loomed overhead. Silence fell and heads were tilted up towards the sky. They remained dead still and alert. A great whoosh could be heard as every bird, perhaps 200 at this point, ascended high into the sky. A peregrine was soaring high, barely within sight, and the starlings twisted and turned as one, evading the threat until it eventually passed.

   As the starlings gradually returned to the ground, it was time for me to leave. I smiled all the way home, my spirits lifted by a wild encounter that many of us can enjoy within our towns and cities, for now at least.

Shoot into the sun


One thing we cannot fully control is the light, and sometimes the sun is simply too bright and high in the sky. A good tip for these situations is to forget everything you've ever learned and shoot straight into the sun, getting the subject lightly underexposed (no matter what you do, the sun will be blown out). You can then recover a lot of detail in post-product ion and create a very dynamic image, especially if you used an ultra-wide lens.
