1. Start off with a new image, whatever size. Create a new layer and call it gradient. Select your gradient tool and click on the properties of the gradient. Then this menu below should appear. Fix the colors and try to make it look exactly like mine! (click on the image to full view - full view is a must)
#30647C
#8CBFD6
#77BBDB
#AADBF2
#2A6986
#83BED9
#E1F2FA
2. Now use these settings for the gradient (these settings are located at the top of the adobe photoshop interface)
3.
Now that you
have all the settings ready, you drag a straight line (hold
shift to make it 90
degrees) Draw the line from the bottom to the top. Now your
done. Only thing I did was to add some small dots on it :)
Now try out your own gradients. Play with the settings, colors
and the way the gradient is set up ;)
