TO CREATE CHROME
First start out with a photo. The photo should be in black
and white, otherwise this'll be a pretty ugly little experiment.
Now, after you've converted to Greyscale,
blur the image (Filter/Blur/Gaussian Blur)
with a radius of about 3 pixels. Next, make
two copies of the present layer. To
do this, click on the little dogeared page thingy
in the Layers palette (Window/Palettes/Layers)
twice.
Now, offset the first copy by
about 5, 5 (Filter/Other/Offset)
Fine. Now take the second copy and offset it the
negative amount of pixels
(i.e. -5, -5)
and set the image's mode to Difference. Finally, experiment
with the image's curves (Image/Adjust/Curves) to
create a nice shiny effect. The curves should look something like the image
at right.
