crw CRW stands for the RAW image format.This format is gaining a lot of popularity nowadays since a lot of the cameras people utilise ( the single lens reflex cameras ) are using this format. The data coming from the image sensor, in the case of the RAW format, is by far the most basic and unprocessed of all. CRW is also known as digital negatives, the RAW image files have quiet the same use as the negatives used in film photography.
eps The legacy EPS format or encapsulated postscript file format was developed as a document interchange format by Adobe systems in 1992 to facilitate cross platform importing and exporting of vector graphical documents between supporting applications and documents. The EPS file is commonly associated with Adobe illustrator and other applications that support the postscript language. The EPS format supports vector graphics, bitmap images, as well as text but is more commonly used for graphic representation. It is worth noting that EPS files exist as final-form representations allowing minimal editing once created. The exception to this is the support of a few transformation operation such as rotation, scaling, and clipping. An EPS file is usually produced to be included in other documents such as text documents.
