Memorable moments and sceneries are best remembered when they are captured in a blink of an eye. In other words, life’s instances are reminiscent when it is taken at an angle, in a different perspective, beyond imagination. Taking photographs may be a hobby, a profession, or just plain fun. It is these pictures that take you to the past, keeps you up with the present, and provides a window to the future - with the help of the camera, technology and of course, a creative mind.
Photography comes from the word photo, meaning, light or radiant energy. That is why photography is the art and science of producing images from light. However, this word means a lot more than it is defined encompassing everyday life and extraordinary ones.
- Light – Different kinds of colors are absorbed by an object in a spectrum and the one reflected back is the color that the human eyes could see. It is essential to understand the direction of the light as different angles produce different shadows, having an effect to the subject. Digital cameras with specialized light settings are indeed important and should not be overlooked. Choose the setting that corresponds to the kind of light the subject is on. E.g. Incandescent – for scenes lit by incandescent light.

- ISO – expresses the speed of photographic negative materials, denoting on the sensitivity of the image sensor to the amount of light. The lower the number, the less sensitive the camera is to light, making the grain finer and to get faster shutter speeds. The generally accepted normal ISO is 100. Auto mode for digital point and shoot cameras are when the camera automatically selects the ISO setting. Take note that increased sensitivity (ISO) to light signal can also result to more noise.
- Aperture – the lens diaphragm on the camera. It is the size of the opening that you set in taking a picture, thus controlling the amount of light the goes through the lens. It is measured by F-stops that are calculated by dividing the length of the lens’ diameter by the focal length. Large aperture settings, such as f3 t f5, tolerate more light through the lens, making the subject the photo’s central element and minimizing the figures in the background. This is ideal for close-ups. Consequently, small aperture settings such as f16 to f32, ensures that the foreground to the horizon are in focus. This is ideal for landscape photography, as this has larger DOF (depth of field). For neither of these extremes f8 to f11 setups can demonstrate well-defined photos.
- Shutter Speed – the rate at which the shutter is open to capture the scene. A wide range of shutter speed gives more liberty in taking pictures because it can be flexible at any situations, may it be sunny or cloudy.
- Composition and Angle – these are the proper placing and position of the subject within the frame. The angle at which the photographer takes the picture and the position of the subject can append significance, denotation, motion, mystery and life to the photograph. Certain positions such as placing the subject elevated connote a forceful subject while lower positions may imply passiveness or anonymity. However, this does not apply to all, as photography is art, it has no boundaries.
The three concepts are interconnected to achieve the proper exposure needed.
- Ultra Compact – This type can be easily slipped through pouches, purses and pockets, which are great for photographers on the go. Unlike their heftier counterparts, these do not offer excessive manual intervening controls, but still take great pictures.
- Canon Powershot SD780
- Sony Cybershot TX1
- Point and Shoot – Ideal for photographers who want to produce high quality images with least the amount of manual controls. Features include optical and digital zoom, movie mode and special image effects.
- Panasonic Lumix ZR1
- Samsung DualView TL225
- Single Lens Reflex – this type uses a form of reflex camera wherein the reflecting mirror retracts when the shutter is released, enabling the photographer to see the accurate image to be captured.
