("OK"), and see a titration curve by clicking on "Titration" (even if it's already checked). It's good to
make sure the system can give back the reference value for a standard following calibration.
It's ideal to correct images for uneven illumination and backgrounds. This can be done using the
REFERENCES sidemenu button. A blank chamber or area from your sample can be grabbed for
background using the "Acquire" button (IMAGE mode). You can also use a ROI as background, if drawn,
to compare values across images vs across time at the same location.

might alter background during an experiment.
Flat-field or SHADING correction eliminates
differences in illumination quality by dividing
images by a correction standard. You need a
uniformly fluorescent standard, like a drop of
standard, and set the camera to near saturation
(but nothing saturated) for each wavelength. You
might get by with one reference if the illumination
pattern is similar for two wavelengths close
together. Be sure to check the 'do it' boxes to
actually turn on corrections.
