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.

Photographic Term of the Week: Color Temperature

leave a comment »

Color Temperature is the description of the color of a light source. Expressed in degrees Kelvin, it’s based on an ideal radiator of light at a particular temperature. Daylight is usually thought of as 5500˚K, incandescent usually 3200˚ or 3400˚ Perceptually, our brains don’t see this difference in color easily, but photographic sensors and films do. Manual or automatic color balance is fairly easily achieved with digital still and video cameras, but situations with differing light sources and therefore differing color temperatures can present challenges.

Something a little different

All from our yard. I can’t take any credit for the planning of what got planted though. Of course for that matter it was the kids that picked them.

RGB, CMYK, SWOP, JPG, LZW, FTP, ICC

More acronyms than a report from the federal government. If you’re in, or close to the imaging industry you’ve probably seen these and more. But what do they mean, and which ones are right for your appliction? This question and others like it have led to a group of imaging professionals and manufacturers, along with their associated trade groups, to form an ad-hoc consortium. This group is dedicated to establishing a set of best practices guidelines for working with digital images. Known as UPDIG (Universal Photographic Digital Imaging Guidelines) they have published their recommendations on everything from monitor calibration to long term storage of digital images available at http://www.updig.org. As much as we artists like to “march to our own beat” and to “think outside the box,” it’s nice to have a set of guidelines that we can agree on and work within.  No use in re-inventing the wheel every couple of days.

best practices for commercial photography

 

or, “What the heck do I do with this?”

Putting together visuals can be a lot like cooking.  There are several ingredients that need to be put together in a specific way in order to achieve the desired results.  Whether your cooking dinner or laying out the catalog, it all needs to be properly prepared. 

We do our homework ahead of time and speak with you, your printer or your production manager and figure out the best way to deliver files in order to have them look there best in the end.  As much as we would love to say that’s the end of it.  There’s still considerations to be made when working with images. From proper sizing to unsharp masking to embedded color profiles, there are few a pitfalls ahead.  Many of our clients are comfortable with these issues, many less so.  In either case we’re happy to answer questions, send variations and in some cases make a visit to the office to help establish best practices.  There are quite a few online resources as well such as UPDIG and Apple’s Pro Color.
