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: L – Latitude

Latitude

This is here is a term which is used to describe a range. Common usage being, a certain camera provides more/less latitude than another one. The range in question is the exposure range, over which one can produce acceptable results.

Mumbai Skyline, Clouds, Sun

The above photo is “As shot” +2 exposure value, while the one below is -1.

Mumbai Skyline, Clouds, Sun, Silhouette

So, one can say that the latitude from -1 to +2 for the camera. The definition is subjective and shall vary from person to person and on their opinion on what acceptable means to them.
Latitude is not the same as Dynamic Range. DR is the range in which, either in highlights or in shadows, details can be obtained before they white or black out, respectively. They are instead related in the manner that, a sensor with a higher dynamic range shall produce photos which have a wider latitude. I had covered basics of High Dynamic Range photos earlier, here!

Last time, L was for Lens Distortion.

Go ahead and produce some amazing photos, and let us all know about it.

Cheers!!

AtoZ Challenge: PH – L: Lens Distortion

for Lens Distortion

The lens refract light and hence certain amount of distortion is introduced. It might be in terms of picture quality, or changes in shape. Common are, barrel distortion and vignetting.
Barrel Distortion is where the photos bulge near the mid of the frame. Its pretty common, but less noticeable in the fixed focus lens.
Vignetting, is when the edges of the photo become dark. In some cases, it adds a bit of drama but, it is still a lens issue.

Often, these are corrected by introducing appropriate lens information corrections during post processing.

Viewing full-screen helps 🙂
