In the 'good old days', when we had finished the day's photography, we would disappear into the darkroom and spend hours breathing in the fumes of nasty, smelly chemicals in the pursuit of our art, now we have Adobe Photoshop.
The RAW file format is digital photography's equivalent of a negative in film photography: it contains untouched, "raw" pixel information straight from the digital camera's sensor. The RAW file format has yet to undergo demosaicing, and so it contains just one red, green, or blue value at each pixel location. Digital cameras normally "develop" this RAW file by converting it into a full color JPEG or TIFF image file, and then store the converted file in your memory card. Digital cameras have to make several interpretive decisions when they develop a RAW file, and so the RAW file format offers you more control over how the final JPEG or TIFF image is generated. This section aims to illustrate the technical advantages of RAW files, and makes suggestions about when to use the RAW file format.
Having a sound knowledge of file formats is essential for digital photography and image manipulation/editing. This article explores the different file formats involved in taking the photographs, their pro's and cons, as well correct use of file formats in a digital workflow. The last section concerns the best file formats for printing, the web, and sharing with friends & family.
This video demonstrates you how to take an excellent close up photograph of the Earth's Moon without a name - also demonstrates you how to develop the RAW (or NEF) files in Adobe Photoshop Lightroom (We use the original LR in this tutorial but similar results in LR 2) and Adobe Photoshop CS3 (similar results in CS4). Enjoy!
