For the Beginner – photography basics.
You now have a new shiny SLR camera huh? That’s great. Now all you need to do is learn to use it. I’m assuming here you got an SLR camera because you wish to accomplish a little bit more than take happy snaps at family events and holidays. So for those new to photography as anything more than that, this short article aims to give you a little background.
Shutter speed – There are two elements to getting a “correct exposure”. They are aperture, and shutter speed, which we’ll look at first. When you press the trigger button in your camera to adopt an image, it opens some sliders, like opening a window. Just how long it stays open, is dependent upon how you set the shutter speed. Shutter speeds ranges from amazingly quickly (i.e. 1/8000 of a second), to quite slow (30 seconds), or even infinity if your camera carries a bulb setting. They are extreme shutter speeds instead of often used, except by those who shoot fast moving subjects, or perhaps in surprisingly low light. For most of us, we often stay with somewhere in the center. As a general rule, the faster the shutter speeds, the sharper your photo will likely be. For many individuals, anything at 1/60 of a second or over is appropriate when hand holding a camera. Lower if you have a really steady hand. If you have to use slower shutter speeds, you will need to employ a tripod or rest your camera on a steady surface. These slow speeds can be especially great for creating blurred results. As an example the flowing water in the waterfall.
Aperture – Ever thought about how photographers get their subjects to really jump out by blurring the background? The secret (which really isn’t secret) is adjusting the aperture. The aperture changes the depth of field within your photo. Depth of field is how most of the look is in focus. One example is, if you have a depth of field of 4 meters, anything within that distance of the subject you happen to be centering on may also be in focus. There is as significantly variety using this type of control as there is with shutter speed. You can decide to set a narrow aperture (long depth of field) if you want the whole shot in focus, for example a great, sweeping landscape, or possibly a wider aperture for portraits.
Ok, you have got your shutter speed sorted from your aperture. Now we merely have to put them together. Any SLR camera could have an inbuilt light meter. This little gadget measures the quantity of light you need to produce a correct exposure. It is almost always available as a little bar with a too high (+) along with a too low sign each and every end. It’s simply a matter of balancing one contrary to the other so that the meter is centered. When you’ve done you could press the button! That’s all there is certainly to it.
ISO – Another choice that will certainly affect your exposure is the ISO you have. With film digital cameras, therefore the speed of film that you employ. If you use a 100 speed film, your ISO is 100. Digital cameras also have a variable ISO speed. It’s only in the form of turning a dial instead of loading an alternative film. An overall rule is to apply the cheapest ISO you can get away with. Higher ISO films or digital settings may lead to noisy (grainy) pictures. They actually, even so, let you more freedom in your exposures in that you’ll be able to shoot with less accessible light. Try out your distinctive camera and see what you might get away with. Keep in mind the high quality required will be different for anyone. Should you simply want to make small prints to put in an album, or just maintain photos digitally on your computer, then you will not need the same quality such as you desire to make large prints to hang on the wall.
So there may be some food for thought for those starting out in photography and seeking to do not only point and shoot. Now it’s time to go out there and shoot. Try new things. The creative side, well, that’s all up to you – your imagination has no limits.
