Just to do video tutorials, for a long time did not write graphics and text tutorials, today we discuss the split channel and then merge the method to color.
With the tutorials, we're not just going to learn how to do this, it's more important to understand why we do this, and then we'll have a clear idea of how to do it again when we encounter similar problems.
What this tutorial can learn:
1, the decomposition and merging of the channels;
2, channel situation analysis and problem solving ideas;
3, magical mixing color band;
4, the application of mixed mode;
Effect Chart:
Original:
We first analyze this image, open the channel panel, you can see, because the leaves are green, from the basic knowledge of the channel, in the image of the leaves, the green channel is the brightest, red and blue channel is darker.
And in the background of the Blue sky part, because the color is biased to blue, so the blue channel is brightest. The red channel and the green channel are all darker.
What we need to do is to turn the leaves red to yellow, so we just need to make the red channel of the leaf part brighter than the green channel, the leaves will be inclined to red, now look, the leaves are a little bit yellow, this is because
Red channel and green channel contrast is not large, if the red channel and green channel are very bright, and the blue channel is darker, then the color must be yellow. This can be learned by learning the basic knowledge of the channel.
Now, the red and green passages of the leaves are not too large, and the leaves are not bright in the blue channel, so we can exchange the red and green channels. This will bring up the yellow red leaves.
Adjust Layer-Channel mixer
By default, in the red channel, Red is 100%, and the other two is 0.
Similarly, in the green channel, Green is 100% and the other two is 0.
In the blue channel, the Blue is 100%, and the other two is 0.
In the red channel, set red to 0% and green to 100%. As you can see, the image immediately turns yellow. This is because we replaced the red channel with the green Channel. The red and green two channels are exactly the same.
Green channel, set Green to 0%, red to 100%, with the original red channel to replace the green channel.
The leaves immediately turned yellow, but the blue sky was gone!
Set the blending options for this adjustment layer on the Layers panel
Set to blue channel (as shown in callout 1)
Press the ALT key, split the lower part of the slider to the Zola, you can see the blue sky immediately appear.
Look at the effect after a cut!
