4.3 Gamma Correction --mehmet.gunal.1, Wed, 13 Feb 2008 17:24:39 -0500 reply

This lab was pretty straight forward. The last part may be a little tricky. For the first section of 4.3, once the Gamma is found from part 4.2, implement y and Gamma values to the inverse of equation (5) to find the Gamma corrected image. For the second section, use equation (5), implement x and Gamma = 1.5. Finally, reprocess the data using y, and previously calculated Gamma on inverse of equation (5), and you should have the corrected image. Good luck!

I am finding it hard to set the Black Point. Any tips?

I believe minor Black Level setting deviations will not have strong effects on the final results as long as you stay close to the directions.

no black level adjustment --karl.ostmo.1, Sat, 15 Mar 2008 01:08:36 -0400 reply

My monitor is a newer Dell LCD model. It has no black level (contrast) setting - I assume they set it at the factory. The lab was completed without issue, though, so you can probably just ignore that part.
