Key Terms and Concepts

Have you ever wondered what the Terms like Jpeg or CMOS and several others like these which are used in today's digital photography world stand for? Whenever I hear of a term like this I am very inquisitive to know more about it and what it stands for. So I thought there must be people out there like me who will be interested in knowing about these terms. Here a few commonly used terms”


CCD/ CMOS- Charge-Coupled Device/ Complementary Metal oxide Silicon sensor.
Digital cameras use one of these sensors to digitally record light coming through the camera lens. Digital media cards store this information, and customers can later export the data to other devices or computers.

JPEG- Joint Photographics Expert Group. A standard method of compressing photographic images. Compatible with most digital cameras, devices, and operating systems, you can identify them by the file extension ".jpg."

Fixed Focus - A lens that cannot automatically adjust its focus for objects that are very near or very far. Instead, the lens has a fixed range of focus.

HDR - Image than current photographic methods .This allows HDR images to more accurately represent the range of intensity levels found in real scenes, ranging from direct sunlight to faint starlight.

PTP - Abbreviation for picture Transfer Protocol. A standard designed to transfer images from digital cameras to computers and other devices without needing additional device drivers
