ABSTRACT
All DSLR cameras can be used at night, but in most cases, the newer the model, the better the
results are likely to be. The biggest advantage of the most recent DSLR cameras is that they
produce less long-exposure and high-ISO noise than older cameras, and this is especially true
of the more expensive full-frame sensor cameras. Full-frame sensor cameras will almost always
produce lower noise levels than cameras with smaller sensors, but noise is becoming less of
an issue as each successive generation of cameras and RAW processing software continue to
improve. Digital cameras are one commodity where you truly get what you pay for, and it generally
is a good strategy to buy the newest and most expensive model you can afford-assuming that
you plan to print your images. If you don’t expect to print your photographs and will only display
them on a Web site, a lesser camera will suffice. The main features to look for when purchasing a
new digital camera are the following:
• First and foremost is the ability to shoot raw files, and full manual exposure controls. • Live view is extremely helpful for focusing and determining composition. • High ISO capability (6400 or higher) is important for performing test exposures in moonlight. • Availability of cable release with built in timer. Aftermarket timers are about 1/3 the price of name
brand timers.
