Nowadays most people are moving toward digital technology to speed up the artistic process, but that doesn't mean you have to sacrifice quality for immediacy. Digital single lens reflex (DSLR) cameras, such as the Canon EOS 5d Mark II, give automatic feedback and allow you to review the work you've just shot so you can determine if you need to adjust shutter speed, brightness or aperture size, giving you more control over your process and product.
These devices are powerful, flexible and can be upgraded without having to continually purchase new technology, unlike a standard digital camera. These are built much like a traditional SLR camera but with digital storage and a screen like a standard digital that shows what you've shot. This helps you make adjustments, change the subject or fine tune other aspects within the frame to get the best image possible.
The other nice addition is storage capacity. Unlike an SLR requiring rolls and rolls of film that's costly to develop, these cameras take memory cards with gigabytes of storage space. You don't need to switch out rolls or pay to develop them, and you don't need to worry about running out of space in the middle of a shoot.
Like a standard SLR camera, there are lenses and flash devices that can be attached to the body of the device to extend zoom and give better shots in difficult weather conditions, such as rain or night shoots. These tools are also equipped with CMOS or live MOS, tools that help deliver better image quality through light absorption without over-straining battery cells. Regardless of which you choose in your camera, it would be wise to buy either a backup rechargeable battery pack or a package of standard rechargeable batteries in order to get the most out of your DSLR camera.
