Dynamic Background Extraction and MultiScale Gradient Correction

These sections highlight various ways to use gradient correct processes. Multiscale Gradient Correction is the latest preferred method. DBE is the manual method that does use any reference data.

Hidden Issues (Common DBE Misattribution)

DBE is often "blamed" for a number of issues. The general theme is that the image looks "good" before it is calibrated or before running DBE. This video highlights this is not the way to interpret what is going on....

DBE: You are in CONTROL (not the other way around)

Here is a perfect example that shows how DBE works in detail with samples... and you can "hijack" the behavior for your own evil purposes (insert maniacal laughter)... An exclusive Adam Block Studios kind of video.

DBE: Use Symmetries First example (M45)

This lesson demonstrates the method of using symmetries first to deal with modeling the background with DBE. This can often simplify gradients and allow for an easier time correcting them.
