  • How to Use Digital Cameras for Time Lapse

    A digital camera can record a sequence of images at a slow rate for time-lapse photography. This sequence produces a smooth motion during normal playback. This time-lapse photography technique can make time appear to be racing or lapsing as the sequence shows an exaggerated process. You can record each image manually for a time-lapse effect. Adjusting the shutter speed, aperture and ISO setting for your particular lighting conditions can ensure that you produce a well-exposed series of images.

  • How to Take Time Lapse Photos

    Time lapse photography involves taking numerous shots at specific intervals over a long period of time. The resulting images will show the progression of a long time period played back at a much faster pace. For example, time lapse photography can show the progression of the sun from sun up to sun down in only a few seconds or a flower opening and closing its petals. Time lapse photos can be accomplished with almost any type of digital camera.

  • How to Calculate Time Delay

    Stringing images together as a series of moments can capture change over time. This technique is called time-lapse photography. The photographer takes an image, waits a specified interval of time and then takes another image. This process can be repeated over the course of a long period. To create a successful series, you will need to make images at the correct intervals. Shoot too infrequently and your sequence will be too choppy; shoot too frequently and your sequence will not capture the way the scene changes.

  • How to Program a TI-83 for Time Lapse

    Your pricey new DSLR can't do time lapse-photography out of the box, which surprises many people. Time-lapse photography involves taking pictures at regular intervals, then stringing them together. The finished sequence depicts a slowly changing scene as if it were moving in fast forward. You use a device called an intervalometer to trigger a camera to take time-lapse photographs. While you can buy an intervalometer, you also can write a simple program on a TI-83, TI-84 or TI-89 graphing calculator that will trigger your camera to take a picture roughly every 25 seconds.

  • How to Do Time Lapse in Imagemagick

    Time lapse photography involves taking hundreds or thousands of pictures of the same scene as it changes over a long period of time and then compiling all the images together to produce a video-like sequence. Pictures are taken at intervals of time ranging from a few seconds to several minutes, depending on how much is changing in the scene. An intervalometer automates this process for the photographer, triggering the camera at the selected interval. The sequence is then compiled together using a video editing program like ImageMagick.

  • How to Time Lapse With a Video Camera

    Dramatic footage of storm clouds building or a beautiful sunset can be captured with standard video cameras by using a technique called time-lapse photography.

  • How to Use the Canon 70-200 mm Tripod Ring

    It's no secret: zoom lenses are heavy things. Not only do they contain a large amount of sensitive, solid pieces of glass, but they are also made of solid materials, like heavy plastic and metal, which add to the weight. Lenses like Canon's 70-200 mm lens are especially so, as they are designed to take the use and abuse a professional photographer will put a lens through. Because of this, and due to balance issues resulting from the length of the lens, Canon has included a special mount on the lens called a tripod ring, allowing a tripod or a…

  • How to Use SMC Takumar 1 1.4/50 on a Canon 1000D

    The fully manual Super Multi-Coated Takumar lens was first produced by the Pentax camera company in 1971. While Takumars without a multi-coating can be found, the SMC versions tend to be favored for their resistance to flaring, contrast and color rendition. Takumars use the M42 mount thread, meaning that the lens is simply screwed into corresponding mount on the camera body. Although the Canon 1000D is much newer and uses a different mount thread, an SMC Takumar can be fitted onto the camera using an appropriate adapter ring.

  • How to Pack a Nikon Camera

  • How to Focus in the Dark

    Most digital cameras have an autofocus feature that is designed to work in conditions of high, low and practically no light. For cameras without this feature or for those nights when the autofocus just can't get the job done, the best way to focus in the dark is to try it manually with the aid of an external flash or simple light fixture. An external light will illuminate your subject long enough to attain the right focus and can then be shut off while the picture is taken.

  • How to Toggle Focus Points

    Many cameras have a built-iin auto focus system. When the user chooses a subject to photograph, software in the camera automatically adjusts the lens focus to ensure a sharp image. The camera may try to detect where in the frame the subject is located. Alternatively it may focus on a point in the center of the frame. Many cameras, particularly more expensive ones with a richer feature set, have multiple auto focus points laid out in a cross, diamond, grid or other formation. The user may be able to set which focus point to use.

  • How to Make Time-Lapse Shots

    Time-lapse photography creates a movie of a location in "sped up" time. These videos can be mesmerizing when done correctly and can reveal an area's activities over hours in a few seconds.
