The software for S-Curve projection now permits the selection of any output on the layout.
Each active output (red) will respond to the S-Curve correction, it is advised therefore that
all outputs are selected for this process. With all selected and a flat white source
displayed over the projector outputs the user can now adjust the S-curve parameter. This
will adjust the brightness on ALL of the blends. By careful adjustment the user should be
able to find the correct value that removes any brightness rise or fall originally seen.
11.3.3 Gamma Correction
The next stage is to correct for any gamma differences between projectors. By clicking on
the S-Curve button it is replaced with individual R G and B Gamma adjustments. The user
should change the input source from White to Red green or Blue. For each of these if they
see a projector outputting a different brightness then that output should be selected on the
software (make it the only one red) and then adjust the appropriate gamma to remove any
visible difference.
