DavidTriplett Posted June 7, 2019 Share Posted June 7, 2019 I'm a coast and mountain kind of guy. I spent a week in North Dakota last summer and found I lost my sense of direction very easily, particularly on very cloudy days. I was grateful for the compass readout in my truck. In such conditions it was startling how grain elevators and similar structures took on enormous perceptual importance. Structures that I would normally pay little attention to became extraordinarily important as landmarks and waypoints in an otherwise nearly featureless landscape. It's a very good case of how relative contrast plays a critical role in human perception. How did you do the color restoration? Link to comment Share on other sites More sharing options...
JDMvW Posted June 7, 2019 Author Share Posted June 7, 2019 How did you do the color restoration? Mostly by the highest value = 'white' and the darkest value = 'black' -- then fine tuning Some of us call it the "Ozone System" :D 1 Link to comment Share on other sites More sharing options...
