ISO
Allows more light to expose image. In very basic terms, ISO is the level of sensitivity of your camera to available light. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The component within your camera that can change sensitivity is called “image sensor” or simply “sensor”. It is the most important (and most expensive) part of a camera and it is responsible for gathering light and transforming it into an image. With increased sensitivity, your camera sensor can capture images in low-light environments without having to use a flash. But higher sensitivity comes at an expense – it adds grain or “noise” to the pictures.
SHUTTER
Mechanical device that lets in certain amount of light. Shutter Speed is one of the three pillars of photography, the other two being ISO and Aperture. Shutter speed is where the other side of the magic happens – it is responsible for creating dramatic effects by either freezing action or blurring motion. In this article, I will try to explain everything I know about shutter speed in very simple language.
F-STOP
Control of light going into camera. The word stop is sometimes confusing due to its multiple meanings. A stop can be a physical object: an opaque part of an optical system that blocks certain rays. The aperture stop is the aperture setting that limits the brightness of the image by restricting the input pupil size, while a field stop is a stop intended to cut out light that would be outside the desired field of view and might cause flare or other problems if not stopped.
In photography, stops are also a unit used to quantify ratios of light or exposure, with each added stop meaning a factor of two, and each subtracted stop meaning a factor of one-half. The one-stop unit is also known as the EV (exposure value) unit. On a camera, the aperture setting is usually adjusted in discrete steps, known as f-stops. Each "stop" is marked with its corresponding f-number, and represents a halving of the light intensity from the previous stop.
TRUE!! Cameras love light!!
Hybrid - Combined computer with photography/video
Depth of Field - Adjust focus
INTERSTING!! Outdoor daylight scenes seem to be a blue light. Indoor light green and candlelight in the dark show light colour as red, but mind naturally filters out those colours which whiten it. Camera's see the true light colour.
WHITE BALANCE
Colour temperature, degrees kelvin (how its measured by instead of heat), where it lies on the colour spectrum. Compensates normal white light. White balance (WB) is the process of removing unrealistic colour casts, so that objects which appear white in person are rendered white in your photo. Proper camera white balance has to take into account the "color temperature" of a light source, which refers to the relative warmth or coolness of white light. Our eyes are very good at judging what is white under different light sources, but digital cameras often have great difficulty with auto white balance (AWB) — and can create unsightly blue, orange, or even green colour casts. Understanding digital white balance can help you avoid these color casts, thereby improving your photos under a wider range of lighting conditions.
Something to remember!!
Daylight - 5600k
Indoor - 3200k
Certain bulbs for different situations, times or surroundings. Maybe look into the different processors on the camera.
KEEP shutter Speed @ 50!!
AVCHD
(Advanced Video Coding High Definition) is a file-based format for the digital recording and playback of high-definition video.
Developed jointly by Sony and Panasonic, the format was introduced in 2006 primarily for use in high definition consumer camcorders.
