A quick Illustration of the art portal that I made. Done in Photoshop CS3...
Well... Don't have much more to say, so I'll tell how its done?
1: Drew the .JPG file first, started with a rectangle and filled it with a gradient.
b: Drew on the "Eyeball" (which is the default JPEG icon on some older computers)
c: Wrote the Classic 256B at the top (lol, 1996 technology)...
d: Bundled those layers into the JPG, locked and hid layer.
2: Next came the Portal.
b: Selected the Maple Leaf brush from the default set, played around with the Jitters such as Hue, Size, Roundness, and Rotation.
c: With the brush settings to my likings, changed the foreground color to Blue. Proceeded to draw a whole bunch of circles.
d: With this done, used the Radial Blur (Set to "Zoom", and Strength of 75) to meld together the circles, ended up with this multicolor rainbow euphoric thing.
e: Desaturated it.
f: Used the Hue/Saturation Adjust Panel (Control+U) to make a nice green, then checked off the Colorize checkbox.
g: Locked that layer, now its time for the Striations.
3. Striations, using a regular circular brush, draw swirls, I used my Wacom with different sensitivities to get a nice mix of swirls.
b: Continue to do this for Black, White, and about 5 shades of green.
c: Use the twirl filter to spin the hot mess of swirls around...
d: Blur them with about a 2.5 Gaussian Blur.
e: Set that layer's Blend Mode to "Overlay" and played with the Opacity value.
4. The shine...
b: Started with a white brush, size 19, 100 Hardness.
c: Drew some "fuzzy" looking circles.
d: Set that layer's opacity to like 65.
e: Repeat steps c and d, each time making smaller fuzzy circles with higher opacity.
f: Merge all fuzzy circles layers.
g: Use a Radial Zoom Blur to zoom about 80 Percent.
5. Finishing touches.
b: Unlocked the JPG layer, duplicated 3 times.
c: Used the transform tool on each to angle them towards the center.
d: Blurred out the edges of the JPGs that were closest to the edge of the drawing.
e: Used Liquify tool to stretch the Files and bend them a bit.
f: Applied an Omni Light to the center of the drawing to give the illusion of light hitting the papers.
