Start with solid dark green color.
Create new layer, switch to Pen tool, make a leaf shape (it will look better a bit unsymmetric, so do not try to make it perfect symmetric).
Apply the following layer effects to the layer with leaf shape: - outer glow - black, overlay, 50-70%, 10-15px - inner glow - white, overlay, 20-40%, 15-25px
change foreground color to darker green (almost black), create new layer, and then, using same Pen tool, start drawing...
Apply the following layer effects to this layer: - blend mode = screen - outer glow - black, overlay, 10-20%, 5-8px
Group the layers containing elements of leaf into one group. Now you need to make A LOT of copies. Here's the hint to speed up process: select group, hold ALT key, and click-drag group to move it. Every time you drag it, holding ALT key, Photoshop will create a copy of group.
After each 15-20 copies, hit Ctrl-T, rotate and resize....
...once again, make 15-20 copies, rotate, resize, make 15-20 copies, rotate, resize, etc.....
after about 30-40 minutes of copying, rotating and resizing, entire image is filled with leaves and no background is visible. Merge all layers and groups into one layer (it is good idea to save backup PSD file before that) and apply the following layer effect: - gradient, radial, black-to-white, overlay, size:150%, opacity: 20-25%. Done!
But what if I wanted to plant some flowers into the wallpaper? Easy! Create new layer, set foreground color to white, switch to Pen tool, and draw shape similar o this.
Switch to Pen selection tool (A), select shape, copy (Ctrl-C), paste (Ctrl-V), rotate 180 degrees, move down.
Then, you might already guess... select all, copy, paste, rotate, select all, copy, paste, rotate, select all, copy, paste, rotate, select all, copy, paste, rotate! (Hint - hold SHIFT while rotating).
Apply the following layer effects: - bevel: shadow = black, opacity: 10-15% - outer glow: black, 15-20%, 2-3px
Duplicate this layer, rotate, resize...
...repeat, repeat :-)
Our flower need special leaves for it too. You can use the original layer you created for a leaf in the beginning of this tutorial. Duplicate it, paste in the layer under flower layers...
copy, paste, rotate, repeat :-)
Duplicate layer, rotate, resize! (I also made shape color a bit lighter).
Another part of flower - in new layer, draw a curved line using Pen tool. then - surprise! - copy, paste, rotate, repeat!
The flower is ready!
Group all layers containing parts of flower into one group, and then - i bet you know! - duplicate, move, resize, rotate, repeat!
I also wanted to create special version of wallpaper with berries instead of flowers. Here's how: set foreground color to red, switch to Shape tool, select Ellipse tool, draw circle (hold SHIFT to make it proportional).
Apply the following layer effects: - gradient: linear, white-to-black, overlay, 10-15% - outer glow: black, overlay, 30-40%, 4-6px
create new layer, set white color, switch to Brush tool, select small hard brush, put one small dot on top of circle. Then, create new layer, set its blend mode to overlay, select larger softer brush, put another dot on bottom of circle, then hit Ctrl-T and resize it horizontally (so that is it ellipse, not circle).
In another new layer (with blend mode set to overlay and opacity set to 40-60%), use black and white small brushes to give more 3D look.
Group all these layers into one group, and then.... (chorus) - duplicate, move, resize, repeat!
Berries need their own leaves too. You already know how to do them, so here are a bit different shapes to create for them...
... this step is also the same as in the beginning of the tutorial (creating leaf)...
and again... duplicate, move, rotate, resize, repeat...
In new layer, add a shadow with large black brush.
The last thing to do is.... Duplicate! Move! Resize! Repeat! :-) That's all! Thanks for your time.
