Need to shoot a camera for eBay, Thingamajig for your employer’s website or pastry for the bake sale? You can get slick, professional-looking results with minimal headache and a very tiny investment using mostly recycled stuff. 

Modern digital cameras perform so well under dim light at high ISO settings that some photographers haven’t used a camera flash for months (maybe even longer). Well, here’s a news flash for them: for a small investment and a little practice they can turn most shoe-mount flash units into a controllable package of portable sunshine.

Wouldn’t it be great if you could resize a batch of images simply by right-clicking them and selecting their new dimensions from a menu? Windows users now can—even on 64-bit machines running Windows 8.1.

For centuries, scientists have labored to understand the nature of light. Some ancient Greeks believed that light was emitted from the eyeball the same way a bat sends out an echolocation chirp which allows him to determine his precise position in physical space. Understandably, there were problems with that hypothesis. Other theories followed. Those who embraced the wave theory were right—mostly. Light behaves like a wave up to a certain point. Similarly, those who professed the particle theory were also correct—partly.
