Time Lapse Photography


To make a long story become short, can be done in many ways, an attractive method that can be used is Time Lapse photography. Time Lapse photography is a cinematography technique, which capture frame rate is lower than the normal frame rate of the movie. For example, the normal film runs at 24 frames per second, but the Time Lapse movie frame can be 1 per second or more, depending on the intentions of the photographer, then the image is played back at 30 frames per second.




Such as recording a sunflower blooming, this process takes a period of a few days. However, when playing back the entire movement, it will be encapsulated in a few minutes, so it will make more sense as time went by so fast. Time Lapse capture is considered to be the opposite of high-speed photography. When a phenomenon happens very slowly and watches them at a faster speed, which enables scientists to see the big picture. At faster speeds, things going on as real as life begins and ends, it will be very impressive in our eyes. The movement of the sun, the stars became very clear.


Time Lapse is an important part of the film; many passages in the film when using this technique will become clear in our eyes. Common objects of Time Lapse photography including wings, the sun or the moon moving, growing, flowers are blooming, the fruit is ripe, the formation of an architecture, people in the city and many others.

Some Tips for Camera Setting


To ensure good data and capture with high efficiency, the first step is to select the setting correctly with the following: file format, color space, ISO setting, white balance, exposure, color temperature, auto focus point, metering mode, and lens.


1. File format:
If you feel confident in your setting of white balance and color temperature, you can use JPEG format. With this format, it provides sufficient quality to edit in the PS. Moreover, the portrait photographer often taken in large numbers, if shooting RAW it is unable to contain too much on the memory card and it will take time to upload basket, adjust white balance, and color temperature, converted to JPEG, which reduces the performance of the photographer.

2. ISO setting:
Select the highest ISO that your camera allows without noise. Normally, low ISO has better results, but later cameras like the Canon EOS 20D can shoot at ISO of 400 and still aren’t noise. Take the advantage of this progress, you can get a high shutter speed and fixed (1/125s) to make the camera select a large aperture. (this is necessary when shooting portrait)

3.White Balance:
This factor determines the cardboard color (cold, hot, neutral). Most cameras have auto mode, but we should consider in each case. (See manual instruction for more detail)

4. Exposure:
The auto setting does not always provide perfect exposure, always check the histogram to see the result. If we see a long black stripe along the right side of the chart, which means that the area was "blown-out" (loss of detail); similarly, if there is a dark stripe along the left side means loss of detail in dark areas.
Over Exposure: loss of detail in bright areas
Under Exposure: loss of detail in dark areas
To overcome this, we use exposure compensation. Increase or decrease to balance the light (see your camera's manual to see how to adjust).

5. Color temperature:
Sunny (sunny daylight outdoors): 5200 K
In the shade (shaded areas outdoors): 7000 K
Mostly cloudy, meters protein, or sunset: 6000K

6. Auto Focus Point: In the portrait, one focus point is enough (Canon 10D has 7 focus points). When shooting, always get the focus point in the eyes.

7. Metering Mode: Select Partial Metering or Center Weighted Metering Mode, especially when shooting close up or when the background is too bright. Select evaluative metering when has a nice background.
