AtoZ Challenge: The Glossary

The AtoZ Challenge has already come to an end for the second time, and as a result, now a glossary of the terms can be made. I believe this shall come handy for future references!

A – Aperture, Artificial Horizon

B – Bulb Mode, Bokeh

C – Colour Temperature, Composition

D – Double Exposure , Depth of Field

E – EXIF Data, Exposure Bracketing

F – Forced Perspective, Focus Stacking

G – Ghosting, Grain

H – Hot Shoe, Hyperfocal Distance

I – Infinity Focus, ISO

J – Juxtapose, JPEG vs RAW

K – Keylight, Kelvin

L – Latitude, Lens Distortion

M – Manual Mode, Macro

N – Normal Lens, Noise Reduction

O – Optical Zoom, Overexposure

P – Panning, Post Processing

Q – Quality, Quiet Release

R – Red Eye Reduction, Rear Curtain

S – Spot Metering, Shutter Speed

T – Tonal Range, TTL Metering

U – Urban Landscape, Underexposure

V – Vignetting, Vibration Reduction

W – Watermark, White Balance

X – X Speed, X Process

Y – Your Rapport, You

Z – Zoom (Digital), Zoom Burst

Have a look at these terms and let me know if I ought to add some to the list.

Cheers!!

AtoZ Challenge: C – Colour Temperature

Colour Temperature

Hot objects emit radiation. If the radiation were visible, say visible light, what would be the temperature of the body emitting the radiation? For example, for soft white light, it is accepted that the body must be at about 3000K. This 3000K is the colour temperature.

The usefulness of this knowledge in photography? Immense, unless you want to spend hours in the darkrooms making the photos look natural. The two photos below shall explain better.

Pug, Yellow Light, Cute, Unrealistic Colour
This one is a no colour correction photo, while the one below is with proper colour temperature settings dialled in.

Pug, Colour corrected, Brown and Blue , Realistic colours
Notice how the colour is realistic now. Since the place was lit by dim yellow lights, everything had a yellow tone, which is not the natural colour.
The settings that need to be tweaked within the camera to get realistic colours is the white balance. Dial in the on which matches your setting best, and shoot away.

Last time, it was Composition.
