much visual information at all. If you don’t mind losing some quality, you can use more aggressive Normal compression with JPEG to cut the size in half again, to 2.9MB.

In my case, I shoot virtually everything at RAW+JPEG Fine. Most of the time, I’m not concerned about filling up my memory cards, as I usually have a minimum of five 32GB memory cards with me. If I know I may fill up all those cards, I have a tiny battery- operated personal storage device that can copy 8GB worth of images (a typical day’s shooting) in about 15 minutes. Although it’s a bit slower, I often copy shots to my Apple iPad because, thanks to its 3G connectivity, I can e-mail them immediately or post them on Facebook or Flickr, no matter where I happen to be.

I also use a netbook with an external 320GB hard drive, and, most recently, a tiny MacBook Air with an 11.6 inch screen (it’s not much bigger than my iPad). For short trips, I rely on my D7000’s capability of copying directly from one memory card to the other in the camera. As I mentioned earlier, when shooting sports I’ll shift to JPEG FINE (with no RAW file) to squeeze a little extra speed out of my camera’s continuous shooting mode, and to reduce the need to wade through eight-photo bursts taken in RAW format.

HIDDEN JPEGS

You may not be aware that your RAW file contains an embedded JPEG file, hidden inside in the JPEG Basic format. It’s used to provide thumbnail previews of JPEG files, and to display images you’ve shot during picture review on the D7000’s built-in screen. That’s right, even if you’re shooting RAW (only), the D7000 still creates a JPEG version, and that—not your RAW image—is displayed on the color LCD.

This is also why you may notice an interesting phenomenon when loading a RAW image into a program like Nikon Capture NX2 or Adobe Lightroom. When the software first starts interpreting the RAW image, it may immediately display this hidden JPEG view which has, as you might expect, all the settings applied that you dialed into the camera. Then, as it finishes loading the RAW file, the application (Lightroom in particular) uses its own intelligence to fine-tune the image and display what it thinks is a decent version of the image, replacing the embedded JPEG. That’s why you may see complaints that Lightroom or another program is behaving oddly: the initial embedded JPEG may look better than the final version, so it looks as if the application is degrading the image qual- ity as the file loads. Of course, in all cases, once the RAW file is available, you can make your own changes to optimize it to your taste.

There is a second use for these hidden JPEG files. If you shoot RAW without creating JPEG files and later decide you want a JPEG version, there are dozens of utility programs that will extract the embedded JPEG and save it as a separate file. (Google “JPEG extrac- tor” to locate a freeware program that will perform this step for your Mac, PC, or other computer.)

This flexibility empowers users to capture clean images even in challenging lighting situations.

The autofocus system of the D7000 is another highlight, featuring a 39-point AF system with nine cross-type sensors. This advanced system ensures fast and accurate focus, making it suitable for a variety of shooting scenarios, from portraits to fast-action sports photography. The camera also includes full HD video recording capabilities at 1080p, with options for frame rates of 24, 25, and 30 frames per second, providing videographers with quality and flexibility.

The D7000's build quality is robust, with a magnesium alloy body designed to withstand the rigors of regular use. It is weather-sealed to protect against dust and moisture, making it a reliable choice for outdoor shooting. The camera features a 3-inch LCD screen with a resolution of 921,000 dots, allowing for high-clarity image review and menu navigation. The 100% viewfinder coverage gives a true-to-life perspective when composing shots.
