Tutorial: A colored swirl of light

Written by devvv (05 Sep 2007 01:23 PM)

Some effects are just very simple to do and look still pretty cool. This one here is such an effect, usable vor all kind of graphics things such as flyers, splash-screens, wallpapers etc. I'll show you how to create such an colored light swirl below!

  1. Create a new Image. 640x480. You can take any size. Apply Filter / Render / Clouds / Plasma.

  2. Now do Filters / Distorts / Whirl and Pinch...

    Whirl angle: 130
    Pinch amount: 1
    Radius: 1

    It should look like that now.

  3. Create a new transparent layer.

    Use the gradient tool, use white as foreground color and black as background color. The fastest way to do this pressing D to reset colors and then X to swap the colors.

    Form: Radial

    Move the gradient from the center of the image to one of the four corners.

    click to enlarge
  4. Duplicate the layer. The original one name "fade black". For this set the layer mode to "Multiply".

    The duplicate, which should be at the top, name "light".

    click to enlarge
  5. Click the light layer.

    - Colors / Brightness & Contrast, use values -65 / +45

    Now apply Whirl and Pinch again. The values should be still saved from step 2, if not enter the same values. Only one value has to be changed: Pich from 1 to 0.8.

    Apply the filter.

  6. Set the layer mode for the layer to Dodge. Duplicate the light layer to enhance the effect.

    Activate the background-layer. Filter / Blur / Selective Gaussian Blur.

    Radius: 50
    Max. Delta: 70

  7. If you want a single color use Colors / Desaturate, then Colors / Colorize or Colors / Color balance like me if you want an icy version:

    Shadows -30 / -30 / +30
    Mids: -30 / +10 / 0
    Highlights: 0 / 0 / 30

    Have fun.

You’re right. I have tried now and it’s ok. Great howto, by the way.

Note to self: do not follow howtos when you’re sleepy. My apologies.

hi! just tried it again and everything works fine. nothing is missing. why do you think something is wrong with the howto?

From: henriquemaia (05 Sep 2007 07:24 PM) – Send a private message

Is this howto complete? It seems to be missing something after selecting the "light" layer mode to dodge. What about the other layers?
