- What is ccd camera and how its work?
A CCD camera works exactly like a regular camera, but instead of focused light falling on film, the light strikes the CCD. A CCD works sort of like an array of thousands or millions of tiny solar cells, each one a pixel, collecting a tiny bit of light and converting it into electrons. The electrons are collected by an analog to digital converter that changes the pixel's value into a digital value. From there, the data is manipulated by a processor or stored to memory.
- What is the difference between a CCD and a lens camera? Could you explain focal length, exposure time, aperture setting, Resolution, Film speed, Shutter time to me?
Focal length - on a digital camera this will be x1.5 that of the non digital camera. For a example a 200mm lens on a 35mm camera is a 300mm lens in digital world. This is to do with the amount of data captured onto the sensor.
Exposure time - This is the same for both 35mm and digital. It's the measurements of blacks and whites in a shot.
Aperture settings - this is also the same on both 35mm and digital. It's how much the 'eye' opens on the camera when you take a shot.
Resolution - this is the big measurement for digital. its the amount of pixals that the cameras sensor is able to capture in an image. In theory the biger the better, but this is not always true, it's also how a camera deals with the pixils. over 6mp and you're good.
Film speed - on a digital camera this still known as ISO but it's the digital equivalent which basically makes the sensor more or less sensitive to light. On a 35mm it's the sensitivity of the film you are using.
Shutter time - this is the same on both. its how long you leave the shutter open during a single shot.
- Is it better to get an HD video camera or a CCD?
HD is only good if you are planning on doing videotaping professionally. Also in order to really benefit from all of the features of HD, you have to have the right lighting and the right shooting angles and the experience to know the difference. There are plenty of 3CCD cameras that give superior results. Last month, I videotaped a fashion show where I exchanged video footage with other videographers who were using HD cameras. The other guys were shocked to find out that the footage from my 3-chip camera came out clearer than what they shot with their HD cameras.
