Understanding Light in Photography

What’s the single most necessary factor you must take {a photograph}?

I assume “digital camera” was the very first thing that got here to your thoughts.

And but there are artists on the market who create photographs with photosensitive supplies with out a digital camera. So what do they nonetheless want?

That’s proper. They want mild.

There isn’t a images with out mild. And I’ve devoted this subsequent submit to all the pieces you must find out about mild earlier than you begin taking well-exposed images.

Drawing with Gentle

The phrase “images” is made up of two phrases with a Greek origin. “Phōtos” means “mild” and “graphé” means “drawing”. So to {photograph} is to “draw” photographs utilizing mild.

Seems like magic, doesn’t it? But it surely’s really physics mixed with both chemistry or electronics.

Let’s learn the way that magic occurs.

Gentle and Movie Images

Once we press the shutter button of a movie digital camera the sunshine that has entered by way of the lens hits the movie. Photographic movie is roofed with plastic emulsion that accommodates photosensitive silver halide crystals. These crystals react to the sunshine chemically and the movie “data” the picture.

You need to take the movie out of the digital camera and develop it with correct chemical compounds in full darkness. In any other case mild will break it.

The digital camera sensor consists of tiny items, pixels. Every pixel measures the depth of sunshine by counting the variety of photons reaching the unit and data this as digital knowledge. That’s it. In a nutshell, the RAW knowledge is the gathering of recorded values of depth of sunshine from every pixel of the sensor. Earlier than we are able to “paint with mild” we have to measure and recorded it.
