  1. What is Resolution • Resolution is the term used to describe the number of dots, or pixels, used to display an image. • Resolution refers to the number of pixels or individual color dots in an image. A high resolution image has more dots, which allows it to display more detail. • A digital camera with a high megapixel count will allow you to take and print larger pictures.

  2. File formats • Photoshop .PSD PSD stands for "Photoshop Document", and as the name implies, it’s Photoshop’s native file format. powerful features that Photoshop gives us, like layers, layer masks, adjustment layers, channels, paths, • JPEG The JPEG (Joint Photographic Expert Group)  • GIF The GIF file format, which stands for Graphics Interchange Format • PNG PNG (Portable Network Graphics)  • TIFFLike PSD files, TIFF (Tagged Image File Format) • EPS EPS (Encapsulated PostScript) • PDF Finally, while most people are familiar with PDF files for viewing

  3. What is RAW and Why ? • A camera raw image file contains minimally processed data from the image sensor of either a digital camera. Raw image files are sometimes called digital negatives, • unprocessed raw data captured by the sensor in the digital camera at the time of exposure. • Normally, the image is processed by a raw converter in a wide-gamut internal colorspace where precise adjustments can be made before conversion to a "positive" file format such as TIFF or JPEG for storage, printing, or further manipulation • Each camera manufacturer created its own unique RAW format:  Nikon .NEF, Canon .CRW, Minolta .MRW, Olympus .ORF, Fuji .RAF, and the list goes on.

  4. It’s the Pro Option • Get the Highest Level of Quality • Record Greater Levels of Brightness • Easily Correct Dramatically Over/Under Exposed Images • Easily Adjust White Balance • Get Better Detail • Enjoy Non-Destructive Editing • Get Better Prints RAW files give the photographer far more control, but with this comes the trade-off of speed, storage space and ease of use. The RAW trade-off is sometimes not worth it for sports and press photographers, although landscape and most fine art photographers often choose RAW in order to maximize the image quality potential of their digital camera.

  5. Additive Color SystemRed - Green - Blue (RGB) This color model is used in computer monitors, television sets, and theater. If you put your eye up against your television screen you might something like the illustration above. The CMYK Color SystemCyan - Magenta - Yellow – Black In the print industry, cyan, magenta, yellow and black are used as the primary colors. When you mix all the colors, the result is gray. If you look at a printed page with a magnifying glass you might see something like the illustration above.
