Learn Photography with DSLR Cameras

This time we will learn some basic knowledge of photography using a DSLR camera. photos with a DSLR camera is not much different with the camera compact / point and shoot camera. like a car with automatic transmission, compact camera / point and shoot has a light setting that is set up automatically. While digital SLR camera has a light and other settings can be set manually or automatically.

If you already have an auto, why should you bother with the settings manually?
If you expect the photos you snap it clear, good color, high pixel, yes, auto function is enough anyway, why dizzy ... But if you want to give a different touch, make our photos look different from the others, making the photos into something can not be seen by human eyes, then you must do the settings manually,

Learn Photography - Never complain with the photos you take the blur (not clear)? The color is not satisfactory? Lightingnya look weird? There are some situations, setting automation functions can not give the best results if you set your own mastering lighting techniques, well, problem solved ..


Three Main Gateway

If we learn mathematics, we will start with 4 basic ie, +, -, x, /, in photography, we start with 3 basic set of incoming light to the sensor, or better known as the three gateways of light, three methodologies, etc.. Thirdly it is the Shutter Speed, Aperture, and ISO speed (sensitivity to light sensor)

Shutter Speed ​​is the speed sensor closing curtain. The more slowly the curtains move, the more light into the sensor. A high shutter speed can capture fast-moving objects clearly, such a moving car, while a slow shutter speed, can record images at a slow pace, while moving objects can look her motion. For an understanding of light entering through the shutter speed, we can use the analogy of the window and door windows. When we press the shutter button, the doors will open this window, and closes again. When the door slowly opened his window, the light coming through into the room more than the doors are opened at high speed.

Aperture is a hole of light entering the sensor. Aperture size is determined by a device called the diaphragm. Light coming in from the lens, moving past the aperture before entering the sensor. The function is actually the size of the aperture size is to adjust the depth of image sharpness. A small aperture has a deeper edge, while a large aperture has a depth that is not in, so that objects that are outside of kedalamanan will look blurry. Toys like the laser, the smaller the hole the laser light, the farther the laser can reflect light, and the more wide skylight, it is increasingly not far could reflect the laser light. We can use again the analogy of a window above the windows and doors to the understanding of light through the aperture setting. If the speed of door opening and closing the window again it is the shutter speed, then the window itself is the aperture because the light entering the sensor through the window. More and wide windows that automatically light coming more and vice versa.

One thing that will always confuse the novice is not determined a large aperture of f number, but vice versa. such a large aperture is f 2.8, while F22 is a small aperture ..

Large aperture (f/5.6)

Small aperture (f32)

Learn Photography - The combination of shutter speed and aperture is the key to determining an image that exists at the proper exposure. When in place such as outdoor light, we can use a high shutter speed with a high aperture to reduce excessive light into the sensor so that the results of the photo is not too bright. Meanwhile, when in place is not too bright such as indoor, we can use a large aperture and shutter speed is slow. But a slow shutter speed is very sensitive to camera movement. Moving the camera when the shutter speed is slow walking will cause a blurry picture. In these circumstances, the use of Tripod (tool where camera stand) or ISO speed can be a solution.

ISO Speed ​​is the sensor sensitivity to light. The use of high ISO could help the sensors respond to light more quickly, but the higher the ISO, will cause noise. Noise makes the picture look not clear.

Learn Photography - With the combination of the three entrances of light, we can adjust the light setting according to the situation and our needs which the Auto function sometimes does not get it right. If we see the object through the viewfinder which is a reflection of the mirror, how do we find a setting that over exposure or lack of light. Usually in the viewfinder there is a light meter for us to set the proper exposure. Likewise, if you do live view of the LCD directly, there is a small meter located bottom or top of the lcd.

There are still many settings and techniques, we will discuss further in the next topic.
