Photographic Term of the Week: Camera Raw

leave a comment »

Camera Raw, or RAW format is a digital storage format for images captured with digital cameras. RAW files have the advantage of containing all of the data captured by the camera, before any digital processing. RAW files are also sometimes referred to as digital negatives. (Adobe’s DNG format is a type of RAW file.) Most end uses of digital images are capable of displaying no more than 8bits of information per color, whereas most digital cameras can capture far more (10, 12 even 16 bits.) Capturing images in RAW format allows the photographer to manipulate the image in post production with less of a chance of technical flaws becoming apparent in the final image.  (IE, more manipulation of color, exposure, density etc – with less digital artifacts like noise and banding.) After post production on the RAW file is complete, the photographer can then convert to a more standard file format such as TIFF or JPEG.

Drawbacks to using RAW include…
Increased file size over JPG
Proprietary format from manufacturer to manufacturer
Specialized software often needed to read and process RAW files.

Photographic Term of the Week: Additive Color

leave a comment »

Additive color is the process of creating colors by combining light. IE, white light (neutral) would be created by combining equal amounts of red, green and blue light. Conversely, subtractive color is the process of creating colors by filtering reflected light. IE, black (neutral) would be created by filtering equal amounts of cyan, magenta and yellow. Additive color is used in transmissive displays (televisions, monitors, backlit transparencies) subtractive color is used in reflective displays (prints)

Note regarding subtractive color in commercial printing: Ideally the combination of C,M,Y inks would produce a perfect black, but in practice they do not. Therefore the addition of a fourth black ink (referred to as K) is used.

A new twist on Maryland crab cakes

leave a comment »

One of our regular clients, Jerry’s Seafood Restaurants, is launching a new fast casual concept of crab cake restaurants. They’ve brought in a tremendous executive chef and the first location should open in Annapolis (of course) this winter.

Photographic Term of the Week: Bokeh

leave a comment »

Bokeh refers to the portion of an image that is rendered out of focus by the lens, or more specifically, the way a lens renders those out of focus portions. Various factors play into a particular lens’ bokeh affect and it’s quality. Bokeh is most visible in images that have a shallow depth of field, as those images have large portions of the image out of focus. Whether or not a lens is said to have “good” or “bad” bokeh is a function of its particular design, specifically aperture blade shape and optical characteristics.
