Hi,Hour glass appears on my nikon d600 after I take photos.What is the problem?Should I bring My camera backTHanks

SOURCE: camera will not respond

hi your memory card had retired buy a new 1 good luck

SOURCE: My nikon D60 is taking dark photos.

The only reason the camera will be taking dark photos is when it is under exposing the image taken. This can be due to the exposure compensation set to under expose the metered exposure. Make sure the expsosure compensation is set to '0' or increase it to compensate for the dark photos.

Also inaccurately metering a scene (such as a high contrast scene) can easily fool the meter into under exposing, especially outdoors.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive. Or you can use a program such as Nikon Transfer ( http://support.nikontech.com/app/answers/detail/a_id/61 ).
