camera action

Well, if you are an expert in photography, this is the mode for you where get will have full control over your camera. Here, you need to take care of all settings including shutter speed, aperture, white balance and flash.

Histogram is very useful tool that gives you quick summary of the tonal range present in any given image. It graphs the tones in your image from black (on the left) to white (on the right).The higher the graph at any given point the more pixels of that tone present in an image.

Before you take your shot, take a gentle but deep breath, hold it, then take the shot and exhale. You can also do the opposite – exhale and before inhaling again take the shot. Its amazing how much a body rises and falls simply by breathing – being conscious of it can give you an edge.

Exposure is the act of exposing the image sensor to light. By adjusting the amount of light, you can make a photograph of a bright sunlit scene look dark, or a shot of a dark interior look bright. Digital cameras have auto-exposure systems that automatically produce photographs of optimal brightness.

Shutter speed is a measure of the time the shutter is open, shown in seconds or fractions of a second. The faster the shutter speed, the shorter the time the image sensor is exposed to light; the slower the shutter speed, the longer the time the image sensor is exposed to light.

Aperture controls the brightness of the image that passes through the lens and falls on the image sensor. It is expressed as an f-number such as f/2, f/8 etc. Lower the f-number, the larger the aperture and more light that passes through the lens. For example, changing the aperture from f/4 to f/5.6 halves the amount of light passing through the lens and halves the brightness of the image that falls on the image sensor.

The quality of a digital photograph depends heavily on the digital cameras resolution – the amount of detail it records. Resolution is defined in megapixels. More megapixels mean more detail, so you can create bigger prints without distortion to the images. Digital cameras have different quality settings, for computer and emailing, you can shoot at lower resolutions. This creates smaller file sizes, making photos easier to edit or email, and means you can fit more on a memory card.

ISO sensitivity is a measure of the cameras ability to capture light. Digital cameras convert the light that falls on the image sensor into electrical signals for processing. ISO sensitivity is raised by amplifying the signal. Doubling ISO sensitivity doubles the electrical signal, halving the amount of light that needs to fall on the image sensor to achieve optimal exposure.

White balance is used to adjust colors to match the color of the light source so that white objects appear white. Subjects may be lit by a number of different light sources, including sunlight, incandescent bulbs, and fluorescent lighting.

Make a right selection of your camera as per the need, for fun photography, use automatic compact digital camera which is small and lightweight, and easy to carry around in a pocket or handbag. This portability means you never have to miss those spur-of-the-moment shots. However, If you want advanced manual control over your photos along with the best possible picture quality, there is no substitute for a digital SLR – known as a DSLR camera.
