Use Variation With Manual Exposure - Seitz roundshot Instruction Manual

4.3 ... use variation with manual exposure

The "variation with manual exposure" tool allows to manually define an exposure
correction curve based on image content. This tool is very useful in difficult light
conditions, especially for indoor/outdoor group photography.
Step 1: Activate the option "variation with manual exposure" in the camera parameters
tab
Step 2: Select the desired "variation parameter". A large variation parameter value is
used for sharp light changes. A small value is used in case of smooth light changes
Step 3: Take an image using a fixed exposure time. At the end of the scan, a flat red
curve will be overlayed on the image as shown below. A flat curve corresponds to no
exposure correction.
It is recommended to choose an exposure time corresponding to the
average light condition of the panorama. This will help to design the
exposure correction curve more accurately.
When using the "variation with manual exposure tool" the 3 fastest
exposure times are not available. This is due to the limitation of the
motor acceleration. This limit prevents sharp light transition to be visible
on the images.
