Editing the flowers with blending modes & tone curve adjustments
I adjust the color balance and brightness of the flowers as I arrange them on the canvas.
I feel that there aren’t enough flowers, so I duplicate some of the flower layers.
In this case, I transform the duplicate layer by rotating, resizing, or flipping it and change the blending mode so that it looks different to the original material.
■ Editing the flowers with blending modes
I change the blending modes of the flower layers to [Color burn] or [Screen]. I usually change the blending mode based on the color of the flowers as below:
・ [Color burn] mode: Bright colored flowers (such as red and yellow)
This makes the color more vivid, and looks like a print or stamp when combined with the paper texture beneath.
・ [Screen] mode: White flowers
This makes the white stronger and creates a fresh effect.
■ Editing the flowers with tone curves
If a flower looks too dark, I use the [Tone Curve] to adjust the brightness or contrast.
I select the layer to adjust on the [Layer] palette, then select [Layer] menu > [New Correction Layer] > [Tone Curve]. I adjust the settings in the dialog box that appears.
▼ I increase the contrast of the water hyssop flowers.
▼ I increase the brightness of the daisies.
Tonal Correction layers apply to all lower layers. If you want to limit the effect to one layer, turn on [Clip at Layer Below].
Move the [Tonal Correction layer] directly above the target layer, and click the [Clip at Layer Below] icon at the top of the [Layer] palette.
When this setting is on, a red vertical line will be visible to the left of the layer.
 Trimming and fine adjustments
Once I decide the flower layout, I use layer masks to adjust the flower outlines.
Since I can clearly see the boundaries of some of the colored flower images, I use layer masks to blur the edges.
While selecting the flower image layer, I click the [Create layer mask] button at the top of the layer palette.
I select the thumbnail of the new layer mask, and use tools such as the [Airbrush] > [Soft] with transparency to blur the edges.
You can create the same effect by drawing with transparency, but the [Layer mask] allows you to revert the changes whenever you want.
Read the following article to learn more about layer masks.
In the same way, I erase the outlines and overlapping parts using the layer masks.
In addition, I adjust the opacity of the flower layers and check how the flowers overlap and look.
 Scattering light sparkles
Here, I will scatter sparkles all over the canvas.
I create a new layer at the top of the [Layer] palette and set the blending mode to [Add (Glow)].
I use a white effect brush to spray the sparkles with a focus on the middle, to add a bright and fresh nuance.
Nokia Inoue’s “Light” brush is available for free on Clip Studio ASSETS. Feel free to use it in your own art!
 Adjusting the overall color
In the last step, I cover the whole canvas with a fill layer to adjust the overall color.
I select the [Layer] menu > [New Layer] > [Fill] and create a fill layer with a orange color.
Note: Please read the following article to learn more about fill layers.
When I change the blending mode to [Overlay], the canvas gets an orange tinge with stronger contrast.
Now, I’ve finished the flower collage which will be the background for my poster.
In the next lesson, I will show you how I create the text and add a grunge effect for a rough, faded look.
