Today's tutorial is from a friend in my group asking: How to extract the flow effect of ink. I have never written this type of tutorial before, so I came up with this article.
Let’s take a look at the final result of the cutout first.
Thinking about ink pictures
Without further ado, let’s look at the pictures first. Such pictures are actually very easy to process, but it is still a little difficult to process them in a hierarchical manner. When I got the pictures, I felt that the shooting quality was not good enough. I felt that the ISO was a bit high and there was too much noise.
Then look at the channels first, check the channels in turn, and find that the green channel is not bad.
Then copy a green channel first
On the green channel in the channel palette, execute the "Select All" command, and execute the "Copy" command to display the RGB channel back in the channel.
Adjustment of ink pictures
After canceling the selection, execute the "Paste" command in the layer palette and paste the contents of the green channel as a new layer.
Make another "Gradient Map" adjustment layer, still using a black to white gradient. The purpose is to make the effect stronger. Of course, you can also use color levels.
Execute Ctrl+Shift+Alt+E. This is the shortcut key for the "stamp" command. It merges all the layers you see into a new layer. (This command is very easy to use, so remember it~ ~~) and create a blank layer below the stamped layer, fill it with white, and hide other layers. (The purpose of not merging is to leave room for subsequent work. After all, no one knows what the image will look like after adjustment.)
We open the blending options of layer 2, and in the layer style dialog box, adjust the "Blending Color Band"
The key to cutout - mixed color bands
Hold down the Alt key and separate the white arrows
After clicking the "OK" button, this is the effect of the cutout by mixing the color bands.
This is far from the effect we want, so what should we do? Back to the channel palette, didn’t we copy a green channel before? Hold down the Ctrl key, click on the thumbnail of the copy of the green channel, and download Enter the selection of this channel
Return to the Layers palette again and click the "Add Layer Mask" button below the Layers palette.
Mask restoration
Of course the result is that the ink is gone. It doesn’t matter. Execute the Ctrl+I command on the mask to invert the image.
Use a black brush to remove unwanted content on the mask.
Add details with a white brush (pay attention to the size and opacity of the brush during these steps)
It's basically done. I'll hide the white layer below the layer and make some fine adjustments.
