It sounds like a reference to dull Halloween costumes, but I’ve always regarded unsharp masking as the Cadillac option for beefing up the acutance of my photos. Admittedly, this is probably just a reaction to the fact that unsharp masking has a complicated dialog box in Photoshop, and my reptilian brain is dazzled by lots of controls.

It wasn’t so long ago when every camera came with what’s called a normal lens. This, of course, didn’t refer to its mental health, but to the fact that it was the default lens that every photographer would find useful or, in the days before interchangeable lenses, would be stuck with.

The first time I came across a reference to bokeh in a lens review I found it a bit pretentious. Bokeh may sound like a Japanese dessert, but it’s actually the out-of-focus behavior of your lens. The term is said to come from the Japanese word “boke,” which translates as “blur” or, in some cases, “senility.” Confused? It’s understandable.

White balance sounds like one of those concerns that vaporized with the advent of digital photography. In the days when film was king, you had to think about the color quality of light at the drugstore photo counter, long before you made any pics. You could either plan on shooting in the Sun, using a so-called “daylight” emulsion, or snapping your photos indoors, with a “T” or “tungsten” film stock.
