And then if we increase the number of iterations we start to…see overexposure because the values are exceeding one.…We're going to now enable the Normalize switch down here…in our code, so let's go over to the editor.…The first thing I want to do…is actually just a little bit of housekeeping.…The base wavelength we determined looked pretty good…in this swatch with a value of ten, so I'll make that…the new default, or initial value.…Float BaseWavelength equals 10.…Then Compile Shader at the bottom,…
