Denim - Material Scan

Another material I scanned to improve my process of 'light scanning'. I think the main reason I failed last time was lack of light accuracy across the surface during capture. To avoid gradient based repetitiveness I struggled with last time, I decided to pay much more attention to light position while moving it around during capture. Also I decided to scan just small pattern so framed just about 10 square cm.
Looks like scan was much better, but there is still place for improvements. Gradient was noticeable there, but not as strong as before. Surface wasn't flat enough so I received few normalmap glitches to deal with with 'Patch Node'. It also forces me to crop finally into 4 square cm area. For the first time I used 'Color Equalizer' node which seems to work pretty well and gives me hope while dealing with repetitive gradient in a future.
I need to try to pay even more attention to light angle and distance during capture and make a try with really flat surface.
