This is one of those zombie ideas that just refuses to die.
1. Do a 10% grayscale calibration with the Lumagen and record the values.
2. Take grayscale measurements in 5% increments and then record the values.
3. Now overlay the former with the latter. When I did this, here's what I get.10% Percent5% Percent
If there were any advantage to calibrating in 5% increments, any at all, you would see spikes in between the 10% calibrated points when measuring in 5% increments. There are none. The only place where improvement is needed is at 5%, and that is only because no calibration was done at 0%. So, do a 10% calibration and then touch-up at 5%. This saves an enormous amount of time relative to calibrating at every 5% increment. If it offered any benefit we would provide it. It doesn't, at least not on the Lumagen.Edited by TomHuffman - 3/25/13 at 1:54am
