Aperture and Depth of Field

Aperture and Depth of Field
Depth of Field Depth of Field (DOF) is the front-to-back zone of a photograph in which the image is razor sharp. As soon as an object (person, thing) falls out of this range, it begins to lose focus at an accelerating degree the farther out of the zone it falls; e.g. closer to the lens or deeper into the background. With any DOF zone, there is a Point of Optimum focus in which the object is most sharp. There are two ways to describe the qualities of depth of field - shallow DOF or deep DOF. Shallow is when the included focus range is very narrow, a few inches to several feet. Aperture The aperture is the opening at the rear of the lens that determines how much light travels through the lens and falls on the image sensor. Small vs Large Aperture Manipulating the aperture is the easiest and most often utilized means to adjust Depth of Field. Aperture Range Distance from the Lens Conclusion You might also like:

Mastering their use is an essential part of developing an intuition for photography.

Cool Open Source Games you should contribute to [Update1 20-07-2011] As per numerous requests, the games list has been updated with some more cool games that I’ve missed. They have been prepended to the top of the list and as before, they are in no particular order. While the popular conception when it comes to games for Linux is that they are almost non-existent, this is only true when it comes to big and popular commercial franchises that are backed up by giant video game studios and publishers like EA Games, Blizzard and Konami. On the other hand, Linux(and other platforms like *BSD) benefits from a myriad of open source and free games, some smaller for casual gaming and others more impressive like MMORPG’s and FPS’s that could compete with some of the commercial games out there in their branch either in the current state or given some fresh amount of contribution. 1.
