Tutorial ] Multiple channels displacement
This displacement was created using the displacements pack 4 'Embellish' but will work with any displacement files
1) Original text before any displacement. Size of document 600 x 600 (Photoshop CS2)
2) Go to to the filter menu and distort > displace filter
3) The displace filter dialog appears, enter 30 and 30 and stretch and repeat. Select a displacement map. The displacement dialog is not very interactive as it offers no preview screen nor can you change your selection without undoing the entire displacement. It is best to know which displacement map to use beforehand, so display all the displacements using the bridge tool or use the supplied displacement gallery
4) Basic displaced text without any change of color
5) Go to the channel palette and select the RED channel and then re-apply the displace filter twice using the same settings
6) Select the GREEN channel and go to the displace filter but set the displacement settings to - 30 / 30 and select a different displacement map file.. Generates a wonderful mishmash of colorful text. Setting the value to -30 instead of 30 will move the pixels in the opposite direction to the original displacements. Only the green channel is modified.
Tutorial ] Glass LAB displacement map
1) Go to the image > mode menu and turn the RGB document into LAB
2) Goto to the channels palette and select the LIGHTNESS channel.
Go to the distort > glass menu to display the glass distortion dialog.
3) Glass dialog. You can change the scaling and smoothness etc of the glass effect
4) Go to the texture drop down and select a displacement map (texture) via the load texture. Apply this to the lightness channel. This can be any displacement map. The displacement map used in this tutorial is one from the displacement pack 4.
5) Re-apply the glass distortion to the A channel and the B channel, use the same or different displacement map / texture. in the case of this tutorial, a different displacement map was used for each channel. The channels palette displays the effect on each of the channels as well as the LAB image overlall
6) Final colorful distorted image, this can now be restored to RGB mode via the image > mode command
