Exif - Nikon D300 Complete Manual

• 14-bit Lossless compression. My default setting. You
lose nothing other than continuous shooting speed, some
card space, and a bit of shutter response using this setting.
• 12-bit Lossless compression. If I'm shooting action
where I need the camera's maximum shooting speeds and
response, I drop the bit-depth to 12-bit.
• 12-bit Compressed NEF. I'll only shoot this format if I'm
running out of card space.
You'll find these settings in the SHOOTING bank
recommendations I provide later in the eBook (which you can
load on your camera via a loadable file on the CD).

EXIF

Even if you're a seasoned computer graphics pro, you may be
surprised to find that JPEG, TIFF, and NEF files contain more
than the image data. This extra information about the photo is
sometimes referred to as metadata
Nikon D300 cameras follow a standard developed by the
JEITA (a Japanese standards body), sometimes referred to as
EXIF (Exchangeable Image File Format). The current standard
version is EXIF 2.21, and is supported by the D300.
The additional data EXIF tags attached to an image include:
• The name of the camera maker (Nikon).
• Camera model (D300).
• The camera's firmware version number.
• Information about the exposure itself: shutter speed,
aperture, exposure mode, ISO value, date/time, overall
brightness of scene (EV), exposure compensation, focus
distance, metering mode, flash mode, focal length, and
even the average compression ratio.
• Thumbnail image.
