3.2.7 HDR
Press the „HDR“ button in the „Parameter“ menu to activate the „HDR“ tab:
This menu is specific for HDR photography, it allows the automatic capture of
bracketed images with defined aperture steps. It is also possible here to merge dng
images into 32bit EXR files using the HDR mixer.
Exposure bracketing: defines the bracketing
parameters to generate the image sequence:
•
Number of images: defines the number of
images in the sequence.
• HDR steps: defines the exposure difference
in f-stops between 2 consecutive images.
• Mean Exp. Time: defines the exposure time
for the median image. It can be manually
selected or automatically computed with
automatic exposure modes.
• Standard TDI: defines the user reference TDI
for the sequence. If the range of scanning
speeds is sufficient, this TDI will be used for
all images.
• Sequence: from fast to slow images or from
slow to fast.
• TDI bracketing extension: when active
some images might be taken with different
TDIs if the sequence reaches the limits of the
scanning speed range.
Based on all parameters an image sequence is generated automatically and displayed
in a table. The capture time of every image and the total capture times are also
displayed. Processing and saving times are not included in this calculation.
Then it is possible to start the image sequence by clicking on the play button in this
menu. Please note that the main play button will only initiate a single image with the
active parameters.
When a sequence is started it is possible to make a pause. This will cancel the image
taken currently and by clicking it again it will restart the sequence from this image. To
terminate a sequence completely, press stop.
