It's assumed for the purpose of this tutorial that you're using
Photoshop and are reasonably familiar with its basic functionality.
You might also be able to use this technique with other similar
packages, eg. GIMP.
If you have any specific questions about any of the stages,
don't hesitate to ask. My email address can be found at the
bottom of the page. Now, on to the tutorial...
Create a new image with a size of 800 x 300 pixels.
Fill it with black.
Select white as the foreground colour.
Use the text tool and enter your logo text. You can use any font
for this, but it should be around 150 point in size. I'm using
"Comic Sans MS" bold at 150 point with the text
"Tutorial". Depending on the number of characters in
your logo, you may need to start off with a bigger canvas, but
make sure there is a gap of at least half the font height around
Make sure the text is rendered to the background by flattening
the image. (Layer -> Flatten -> Image)
Select the Gaussian blur filter
(Filter -> Blur -> Gaussian Blur)
and drag the radius slider up to about 5 pixels. (If you are using
a fairly thin font you may need to reduce this slightly if it
blends the letters together too much). Apply the blur.
Select the lighting effects filter
(Filter -> Render -> Lighting Effects)
and set the parameters to those shown in the screenshot.
Then adjust the lighting direction line in the preview window so
that the black square is at 45 degrees to the Northwest of the
white circle. You should adjust the distance such that it's just
far enough away to keep the background black or almost black.
Apply the lighting effect.
Use the eyedropper tool to sample the background colour. It
probably won't be quite black, but a dark shade of grey. Make
a mental note of the numerical value of the largest RGB colour
component. (Though they should all be the same, so it doesn't
matter which you pick)
Select the levels tool (Image -> Adjust -> Levels). Set the left
most "Input level" value to one greater than the number you noted
in the previous step and set the middle "Input level" value to 1.50
Apply the level correction. The background colour should now be
black, and the logo slightly lighter than it was.
Create a new layer.
Select the Linear gradient tool and pick the
"Spectrum" gradient type.
On the layer you just created, apply the gradient from left to
right across the whole canvas. (Holding shift down whilst
dragging will make sure the gradient is straight)
Change the layer type to "Overlay" to let the
spectrum gradient colour the first layer.
Flatten the image. (Layer -> Flatten Image)
If you want the image for a black background then that's it.
You've finished! If not continue to the next step.
Select the background parts of the image using the colour range
tool. (Select -> Colour Range) Make sure fuzziness is set to 0
and click anywhere outside the text in the preview window before
You should see the moving outline of the selection around your
text. We need to move this away from the text slightly by
using the selection contraction tool
(Select -> Modify -> Contract)
with a value of about 8 pixels.
Feather the selection (Select -> Feather) by 8 pixels.
Select as the foreground colour whatever colour you want the
background of the logo to be.
Use Edit -> Fill, and select foreground colour as the fill type.
Fill the image.
Crop and scale the image to the size you require.
And there you have it... One finished logo!
