sSo to start off with is a 650x500px canvas with a teal-ish colour to begin with.<br />sNext, I’m going to make the ‘background’ of the poster. <br />
Make a new layer
Chose two colours in the palettes. (Blue and light purple)
Make sure the current layer is selected and then go to: filter – render – clouds
Next go to: filter – blur – motion blur. Set the distance to around 100 pixels, and choose the direction you want the motion to go in.
sSo far you should have an image similar to this.<br />
sNext, I would use the blending property – hard light, to get the following effect.
sThen, use splashes of other colours which would match the theme to blend with the current background. (Such as overlay, screen etc) You could also use textures as well as other images. Do it however it suits you.-This is what I currently have-
