Image Orientation
The Image Orientation function sets and stores the orientation of all
subsequently captured images. Select 0, 80, 180 or 270 to force the back to
mark images as captured with that orientation. The Auto setting uses the
back’s built in orientation sensor to determine the orientation at the moment
of capture. Changing this setting will not aect how captured images are
displayed on the LCD.
Sensor +
The Sensor+ function can be either switched On and O. Select On to
capture les using Sensor+ technology which will enable access to a higher
ISO range from 200-3200 and get a substantially faster capture rate.
Images are also captured at a lower resolution. The IQ180 shoots at 20
megapixel resolution, the IQ160 at 15 megapixel resolution and the IQ140 at
10 megapixel resolution.
Set Sensor+ to O to capture les at full resolution. See the IQ Series data
sheet on page 79 for more information.
File Format
An IQ back can save les in two dierent formats; IIQ Raw L and IIQ Raw S. IIQ
stands for Intelligent Image Quality Raw. IIQ L is the default setting and it is
a lossless capture format. IIQ S is a smaller le that is not a totally lossless format.
The IIQ L is approximately 1/3 le size of a processed TIFF le. IIQ S is approximately
1/5 of a processed TIFF.
