  ClearPlus / advanced color-correcting tutorials

  Posted by Jim Curtis on December 31, 2019 at 12:57 am

  ClearPlus (available on AeScripts) is a magic plug in for putting highly saturated blue and cloud contrast into skies, but it’s crashy, doesn’t work at all currently on my system with Catalina, and can look plastic on high settings. It’s also sold as making underwater footage more clear, but I have no footage to test it on. But, I have plenty of available light exterior footage that could benefit from sky beautifying.

  I’d love to learn how to do what it does with Lumetri or Colorista IV, if that’s possible. Can anybody can point me to some tutorials on how to saturate skies without throwing off all the other colors or using secondaries?

  Some seriously advanced color-correcting tutorials perhaps?

  A challenge I’ve had with the secondaries in Lumetri and Colorista are that the mattes they generate can’t be expanded (reverse choked). When using them with no blur the edges are often aliased, and with blur the edges can have a glow or halo that doesn’t look good.

  -For strong sky colors:

  In hue vs sat, raise blue sat, then in hue vs lum, lower the lum of the blue. this will increase the chroma of blue without raising saturation. (change
  the curve shape to restrict, expand the selection.)

  you can also get a similar result from an adjustment layer set to transfer mode ‘color ‘with levels white output lowered 20%. Any clip underneath where you’re
  attempting to raising saturation will get color compressed and get fatter in the vectorscope but not extend outwards. This is similar to how film/arri digital cameras respond and how they restored the good, the bad and the ugly.

  -For removing haze:

  You can use these steps in other programs. But here’s how its made in ae/photoshop/premiere
  1. duplicate your main layer
  2. create new curves effect above, drag the gamma

  down around midpoint 15% so image gets darker
  3. with the white mask of the previous effect
  selected, go to image, apply image(leave defaults as multiply)
  4.create new effect curves above it, raise its black
  point up halfway so you’re not clipping black.
  5. new curves effect above, set transfer mode to multiply(very important step). create a custom curve that starts at the left black histogram and sharply
  tapers at the white point.
  -How it works. The apply image reads off the original and create a chroma midtone effect and the multiply transfer of the top curve reads it back linearly. in
  essence, un-wraps it again.You get all the benefits of haze removal and strong
  colors with none of the tonal loss usually associated with complicated luma mattes or mushy multiplied colors.

  -Fixing underwater footage:
  you can try RGB mixer or for harder stuff, read this

  Thanks so much for the tips, and the detailed step-by-step.

  I’ll give them a try. Thanks again!
