Film image restoration editing example
As a sample, I use the image previously presented. This is original image.
[Original image]
This image contains the following channel images.
[Channel B]
[Channel G]
[Channel R]
In this image, channel B is deeply damaged and G is slightly damaged. Channel R is less damaged. Therefore, I use channel R to restore damaged channel images.
(1) Remove uneven cyan cast with “Relative Color Correction” CTL script.
[Editing target areas]
[Cyan cast correction]
Increase the value of R to correct cyan cast.
(2) Add editing instance and select “Channel Reconstructor” to restore B channel.
(3) Set parametric mask L to select sky.
(4) The B channel is deeply damaged, therefore substitute B channel image with R image. To do so, first in “Mixing Channel”, move Red channel slider to 1.0 and move other channel sliders to 0.0. Next, adjust Lightness and Gamma correction sliders to get appropriate image.
(5) The next step is to correct and edit G channel image. In this time we mix R image to G image, because G image is not such damaged. As above step, we add new editing instance and select “Channel Reconstructor”, and select G as restoring channel. Set parametric mask L to select sky just like previous step.
(6) After confirming G and R image with “Mixing Channel View”, mix R channel to G channel. If value level difference of two images is not negligible, you may adjust the channel level with Gamma.
(7) After channel mixing completed, adjust the white balance.
(8) Finally adjusting tone using tone equalizer and tone curve.
(9) Output the restored image.
