An Adventure In
Space
by Wizaerd
Date Posted: 10/23/2001 - I'm sure that this is
probably 'old hat' for Canvas users who've migrated from other imaging
applications or have experience with other imaging applications, but I figured
I'd write it up anyways just in case new users would like to know.
The
techniques described here are not heavily laden with 'technical' know how,
instead they were basically stumbled upon. Will you learn the latest and
greatest imaging techniques by reading this tutorial? Absolutely not. Will you
create a fairly cool space scene? Yup.
Start out by starting Canvas. In
your document create a paint object by going to Image->Area->Create. I've
created my image at 426x227 with a resolution of 72 dpi. You are more than
welcome to create your image at any size and/or resolution you'd care to.
(experimentation with the resolution will be important because we'll be using
the Add Noise filter, and it's result is greatly affected by your image's
resolution) Be sure your background is set to Opaque and make the background
color black.
Select
your newly created paint object and duplicate it twice by going to
Edit->Duplicate. Set these two duplicates aside for now. Select your initial
paint object, and add some noise Image->Filter->Noise->Add Noise.
Choose a fairly high setting, but also be sure Gaussian and Monochromatic are
selected.
Now go to Image->Blur->Gaussian Blur and apply
a very low blur to your image.
Now go to
Image->Adjust->Levels to bring up the levels dialog. We're going to be
pushing our little deeliedoos (yup, that is a technical term) towards the
right. If in doubt of what I mean, refer to the following image. Using your
preference and taste, adjust the deeliedoos until you get a nice looking star
field.
Set this paint object aside and go to one of the
duplicates we created earlier. When it is selected, go to
Image->Filter->Artistic->Lens Flare. (of course this will either
require Canvas 8 or a lens flare plugin from a third party) Place the flare
wherever you want it in your main space scene. When you have it where you want
it, put the paint object containing the lens flare over the top of your star
field (yup, be sure to check the stacking order so the flare paint object is on
top) and apply a Screen Transparency. (You could've created this lens in your
initial star field, thus requiring only two paint objects, but if you ever want
to adjust your lens flare, you'd have to re-do the star field as well. This way
you can manipulate or tweak any 'layer' you want individually)
Before moving on to the third paint object, change your fill
color to an appropriate spacey color. I chose red, but green, blue, etc works
just as well. Now select your third paint object and go to
Image->Filter->Render->Clouds. You may have to run this several times
in a row to get the kind of gassy cloud you want for your space scene.
Check to make sure your 'cloud' image is on top, lay
it over your starfield and lens image and once more apply the Screen
Transparency. You should now end up with a space scene.
You can further tweak additional transparency settings to your liking,
and boom... you've got the easiest space scene you'll ever create.
