Starburst Effect Photo Tips: Make Lamp Looks Like a Star

Making light source night seemed to glow like a star making our night photos look better. This effect is usually called a starburst effect. To create a starburst, the fundamental thing we must understand is making the aperture as small as possible, which means that we should use a large aperture number (f / 11 to f / 22) and should utilize a lens that has a shorter focal length.

Why should it be like that? well, it will be a long explanation. In short is in the physics of light will experience diffraction (spread) as it passes through a narrow hole (narrow hmm ...). The nature of the propagation of light is what makes the light source (lamp, moon, sun) will look luminous and has a tongue, tongue amount will depend on the number of blades (blade) aperture in your lens, see spec lenses you have, there will definitely be written "aperture blade ". While the answer to why you should choose a large f number and focal length are more pendk, please read the article Understanding Numbers and Understanding Lens Aperture in Aperture.

If still unclear, please see the following picture:

The image above shows, the smaller the aperture (the larger the f number), the tongue will get maximum light. Meanwhile, in a small f number, the visible light source with no burst at all.
Photo Tips Starburst Night:




Use a Tripod - Photographing the night with a large f number, eg photo above with f / 18, making the shutter speed will be very long, over 25 seconds BHotel photos why ?. So make sure you use a tripod so that the images do not like painting graffiti.
     Note the camera settings - To type of photos like this, use a large f number: f / 11 or greater. Set the ISO at a low rate, below 400, because we are going to shoot long exposure. You can use the manual mode or aperture priority, which clearly note the number the camera's metering. For shooting at night as there is a tendency to be the result of over-exposure (too bright), so use exposure compensation figure vary depending on the surrounding environment, try to use as under 1 stop early and adjust afterwards.
     Setting Focus - With a large aperture number, we will not focus too dizzy to think about, but if you want to safely take the focus point manually, or set at infinity.
     Take advantage of the alerts highlight the camera - you know? The bling-bling, you know the warning that appears on the LCD when we are shooting a bright subject.
     Start Photographing - and do not be lazy to repeat and change the settings if the results are not as you wish.

Okay good luck.
