User manual HASSELBLAD H4D-31 DATASHEET V1

[. . . ] the H4d-31 features CCd sensor measuring 33. 1 × 44. 2mm - almost twice the physical size of the largest 35mm dSlR sensors. Consequently the sensor holds more and larger pixels, which deliver the highest possible image quality without gradation break-ups in even the finest lit surfaces. Basic iSO rating is from iSO 100 to iSO 1600. [. . . ] to set focus outside of this center area, the photographer is still forced to focus first, and then shift the camera to reframe, with the resulting loss of focus as a result. to overcome this problem, Hasselblad has used modern yaw rate sensor technology to measure angular velocity in an innovative way. the result is the new absolute Position lock (aPl) processor, which forms the foundation of Hasselblad's true Focus feature. the aPl processor accurately logs camera movement during any re-composing, then uses these exact measurements to calculate the necessary focus adjustment, and issues the proper commands to the lens's focus motor so it can compensate. the aPl processor computes the advanced positional algorithms and carries out the required focus corrections at such rapid speed that no shutter lag occurs. the H4d's firmware then further perfects the focus using the precise data retrieval system found on all HC/HCd lenses. The plane of focus changes when the camera is tilted for composition. The middle image shows the result when not using True Focus. While this image looks relatively sharp, the rightmost image where True Focus has been used, is razor sharp.

"digital lens Correction" (daC), is an automatic correction of the images based on a combination of the various parameters concerning each specific lens for each specific shot, ensuring that each image represents the best that your equipment can produce. Accessories including GPS Recording Flexibility Hasselblad's global image locator (gil) is an accessory for use with any Hasselblad H-System digital capture product. With the gil device, all images captured outdoors are tagged with gPS coordinates, time and altittude. this data provides the key to a number of future applications involving image archiving and retrieval. One example is the direct mapping of images in Phocus software to the google Earth application.

Phocus for professional level workflow Phocus provides an advanced software toolbox that has been especially designed to easily achieve optimum workflow and absolute image perfection from Hasselblad raw image files. With the H4d-31 camera system Phocus provides: · Uncompromising Image Quality · Special extended camera controls with which to operate your H4d-31 camera. these features, such as live video for easier shot set-up and workflow, or the ability to control the lens drive for focusing when the camera is in a remote position or when the digital capture unit is mounted on a view camera, bring an entirely new level of flexibility to the way you shoot. · Moiré Removal Technology automatically applied directly on the raw data, leaving image quality intact and eliminating the need to carry out special masking selections or other manual procedures, saving hours of tedious post-production work.
