Photographs provide a visible record of life's most cherished moments, just as the skin provides a visible record of the number of times you've frowned after dropping an ice-cream cone. Document the happier times with today's Groupon: for $50, you get your choice of a two-hour photography class at Wirken Photography (a $100 value).

Tyler Wirken draws on a background in photojournalism to educate novice and intermediate photographers in the art of shutter snapping. Three accessible class options include camera mechanics, which teaches novice shooters how to take advantage of basic camera functions, manipulate exposure, and use flashes to temporarily stun anyone who comes too close to their hidden stashes of Mr. Goodbars. An extensive camera-control class delves deeper into handling exposure and device settings, allowing those who shoot at the intermediate level to manipulate cameras like devious puppeteers. Light-and-composition classes teach how to cast everyone in the best possible light and why white balance isn't appropriate after Labor Day.
