Framing on your photo

Framing is the tactic of using natural surroundings to add more meaning to your subject. It could be anything such as bushes, trees, a window, or even a doorway like in the picture at the top of this page. In the process of doing this you need to be careful that you don't only focus on what's framing your subject. Make sure you focus on the main subject, and also it is a good idea to use a narrow aperture (high f/stop) to achieve a high depth-of-field. It also wouldn't hurt if the part of the picture framing the subject was darker so make sure you take your light reading on the main subject.

Foreground Elements in your photo

In order to show the depth of a landscape it is very important to include some type of foreground element. Without something in the foreground, the viewer has no way to distinguish distances or sizes; everything looks more flat and closer to the camera. A foreground element adds a substantial amount of improvement to what would be a drab amateur photo. But when using foreground elements in landscape photos make sure you use a very narrow aperture (high f/stop) so the whole scene will be in focus.

KAF-50100 The 51 MP CCD Sensor from Kodak

The KODAK KAF-50100 is a four output, high performance CCD (charge coupled device) image sensor with 8176(H) x 6132(V) photoactive pixels designed for a wide range of color image sensing applications. Each pixel contains anti-blooming protection by means of a lateral overflow drain (LOD) thereby preventing image corruption during high light level conditions. A Pulse Flush Gate (PFG) is available to remove charge from every pixel. A Fast Dump Gate (FDG) is available to selectively remove a line of charge during readout. Each of the 6.0um square pixels are selectively covered with red, green or blue pigmented filters for color separation. The sensor is housed in a 52 pin, PGA package with 100 mil pin spacing.
