Produce a sharp razor blade is the desire of many who whet lovers of photography, and a variety of features as well as additional accessories have been created to help us produce sharp photos. From tripods, stabiliser (lenses or camera) until the software image editor that comes with the tool to sharpen the end result photo.

This article will summarize a few tips to keep your photos sharper:

How to hold the camera
How to hold the camera very influential on the stability of the camera (read: sharpness of photos), please read how to hold the camera is good.

Shutter Speed.
If you accelerate shutter speed, then your images will be increasingly sharp. Remember the rule that a photo is sharp when you take pictures handheld: “use the shutter speed faster than your lens focal length”. This penjabarannya:

* If the length of your lens, 50 mm potretlah with shutter speed 1/60 seconds or faster
* If the length of your lens, use a shutter speed of 100 mm, 1/125 seconds or faster
* If your 200 mm lens length, use shutter speed 1/250 second or faster

Aperture
The Aperture effect on depth of field (focus area in the photo). Reducing the aperture (enlarge the number of your choosing, for example f/22) will add depth of field, meaning that the sharp area in the photo will be the greater includes objects that are close or far away, so the sharpness of the photo overall quite reduced.
Then do the opposite, select a larger aperture (smaller number, e.g. f/4), then you will focus sharply just near the focus area. Choose large aperture lets you get a faster shutter speed.

ISO
Add ISO number will accelerate shutter speed as well as allows you to select the aperture. If you’re photographing indoors, zoom is the ISO, but don’t overdo it (eg: select ISO 600 to photograph in the House). Choose ISO too high (above 800), can cause noise (small black spots) in the photo began to look.

Focus
Don’t just believe with autofocus camera, check carefully using your eyes in the focal point is located. When photographing a face in close range, make sure the focus falling diarea eyes. When photographing objects, make sure the focus is there where you want the area most sharply. Autofocus cameras could be wrong and thus dropping focus beside the object that you want.

Lens
If you happen to have a SLR camera, choose the best lenses you can buy. Good quality lenses can drastically improve the sharpness of your photos. The lens KITS are usually offered for sale as a complete package with the camera usually his crappy quality. My advice, if you will buy a new SLR camera, buy separately between camera (body only) and the lens. Don’t buy the KIT package. Good quality lenses are usually marked with a large aperture (e.g. f/2.8).

Sweet Spot Lens
The lens has a sweet spot – his respectively. Sweet spot is certain where the lens aperture will produce the sharpest images. Sweet spot lenses usually are two stops above the maximum limit the ability of the aperture of the lens. For example, for a lens f/2.8 then his sweet spot is f/5.6. Then use aperture f/5.6 If you take a picture with that lens, your photos will be sharp who whet razor blade.

Tripod
The Tripod is cumbersome and inconvenient, but if you “sudi” bring it on, you will gain a sharper image. Especially if you want to generate photo HDR or panorama, be carrying a tripod.

ISO number in digital photography is the ability to capture light sensor technology. The higher the ISO number, the greater the light can be captured by the sensors. However, they are missing is the emergence of noise with increasing the ISO number gives a chance. This noise looks like a freckle – a small granular spots which spread all the photos. When the image in zoomed to 100% the noise is so clear. Apart from causing noise, the ISO number addition can also lead to reduced quality image is produced, for example: color does not appear, so the detail is lost and so on.

The value of ISO number on the camera in general is 100, 200, 400, 800, 1600, and 3200. Professional DSLR camera like NIKON D3 is even capable of achieving the ISO number of 6400, 12800 and 25600 with a very low noise. As the technology developments do not be surprised if the next few years will be better digital sensor, capable of supporting high ISO number but with minimal noise.

The use of ISO number

In general, it is recommended to set ISO number as small as possible. The smaller the ISO number, the smaller the resultant noise, so the result is better pictures especially if you plan for in-print in large sizes. Small ISO number is also suitable for shooting landscapes or scenery where the noise to a minimum desideratum. Fuss when photographing landscapes usually at times where it is less light: sunrise, sunset or night. Inevitably, fans of these types of photos should be prepared tripod or the like to be able to use a long shutter speed.
