Cut out ink, use Photoshop to cut out the artistic effect of ink – Cut out transparent objects

Today’s tutorial is from a friend in my group asking how to extract the flow effect of ink. It seems that I have never written this type of tutorial before, so I came up with this tutorial.
Let’s take a look at the original image and the final result first.

Thoughts on 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 new layers. (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
Press the Alt key to separate the white arrows

After clicking the “OK” button, this is the effect of cutting out by mixing color bands

This is far from achieving the effect we want, so what should we do? Back in the Channels palette, didn’t we copy a green channel before? Hold down the Ctrl key and click on the thumbnail of this copy of the green channel to load the selection for 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 trim away 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. Now hide the white layer below the layer and make some fine adjustments
