DIY Ring Flash with an Old Strobe and a Plastic Container

One of the things about macrophotography is that you either have to shoot wide open (and have a depth of field of about 1 micron or so) or stopped down to get some decent DOF (but have ridiculous shutter speeds making everything a blur). The solution: put a strobe on it! Given that you are so close to your subject, it's hard to properly light it. A ring flash is a good choice and at the tiny distance it is used from the subject, it has the effect of a large softbox creating even lighting.

Toss Your Battery Charger Cable with a Apple Duck Head Adapter

Some battery chargers (e.g. those that come with Canon's pro and prosumer cameras) plug directly into the wall and have prongs that fold into the charger, while others (e.g. the Canon T2i charger) connect to the wall via a removable cable. Though this may be more space efficient when connecting to a socket or surge protector, the extra chord takes up space and can be a hassle. CheesyCam has a clever solution: use an Apple wall plug duck head adapter to transform the charger into a wall charger.

Amateur Transformers Short Film Created with Entry-Level DSLRs

The latest Transformers movie to crawl out of the Hollywood cookie-cutter machine had a budget of $200 million. The above 2.5 minute short film was created by Amateur Russian filmmaker Alexander Semenov using a Canon 550D (with a 18-55mm kit lens and 50mm 1.8) and a Nikon D5000 (with a 18-55mm kit lens). In other words, the gear used was entry-level quality with kit lenses.

How to Use Ultra-Fast Lenses on Modern DSLR Cameras

The ratio between the focal length and the aperture (diameter) of a lens is called the f/number. The smaller the f/number, the more light is let in. Fast lenses start around f/2.0, and the light let in goes as the inverse square. Compared to f/2.0, f /1.4 lets in twice as much light, f/1.0 four times, and f/0.71 eight times. The fastest camera lenses designed for DSLRs and widely available are between f/1.4 and f/1.2, but lenses as fast as f/0.75 have been made in quantity for special applications, and some of those are available quite cheaply via scrap yards, surplus stores, or eBay.

These ultra-fast lenses usually are branded either Kowa or Rodenstock and were designed for use in medical or semiconductor industry equipment, etc. They are not well-suited for use on DSLR cameras, and are no substitute for an f/1.4 or f/1.2 lens that was designed for your camera. However, they easily can produce very distinctive images. Here's how to use one on a DSLR.
