In photography techniques this time I'll bring the article Basic DSLR technology. The initial steps that must be learned to master the DSLR is the Shutter Speed, Aperture / diaphragm and ISO. Because those three things which will produce a photo with composition and tonal. I'll try to explain one by one on all three issues based on science with theories that I have, as well as long experience using digital SLR cameras.
Shutter Speed is the speed of opening and closing of curtains. This speeds which will determine how many rays are captured.



• Bulb - meaning that the speed of opening and closing the curtain on his own set by clicking our finger on the shutter release. So that the bulb can be an alternative when we do not find the shutter speed that is provided by the DSLR. However, using a bulb sometimes requires a strong instinct.

• Slow Speed, is the category of low speed in shutter speed. The numbers are starting from the more than 2 seconds until like thirty seconds (1/30s). Slow Speed is usually used when the condition of objects, foreground and background light minimal. But there is a risk that must be paid when using a slow speed, use of objects should not be on the slow speed moving objects and for maximum results, should use a tripod / support so that the image does not shake / shake. Yet few actually take advantage of slow-speed photographers to produce an image of high artistic merit, such as techniques used for panning on a vehicle or used to target the flow of the river so as to produce a gentle flow of rivers like the snow. Or is also used to generate a laser / light trail at night. Gambr this one when I use the technique of slow speed at night.

• Fast Speed, is the category of high speed in Shutter Speed. Numbers starting from like forty seconds (1/40s) to more than like a thousand seconds (1/1000s). Fast Speed is usually used for objects with full light conditions and high speed, so it does not need something to prop the camera. Fast Speed digukanan very suitable to freeze something, like a bee that was flying to and fro, a motorcycle rider at high speed even, there is a special camera that was created to implement the Fast Speed so that it can freeze a bullet that was shot.
Thus the first discussions about shutter speed as an initial step to be able to master the DSLR camera new entry. Good luck.
