How can I achieve this effect on my text?

Question

I have recently scattered through the portfolio of a designer named Nicolas Girard, and noticed this fascinating typography art:

I looked through the entire web and in every Photoshop and Illustrator tutorials site I know and tried to find an explanation to something somewhat similar to this text effect but I could not find anything...

Does anyone have any idea how I can achieve this Diagonal-Lines-Gradient-Effect on my text? I am using Adobe Photoshop & Illustrator, both CS5, and I have a bit more than basic knowledge. Thanks.

Answer 1

I did a little extra, so as far as creating those gradient lines go.. this is a _little over the top and under the bridge and beside the waterfall...

In Photoshop

1. Make the text
2. Apply the proper Layer styles from Blending options _{( You can get there by right clicking the text layer and selecting it from the list. )}
3. Make a group ( Above text layer ) Then make a selection from the text by clicking text layer thumbnail while pressing (Ctrl). Once selected click Layer mask icon at the bottom of the Layers panel.
4. The Diagonal lines - Inside the group make a new layer (Ctrl+Shift+Alt+N). With Polygonal Lasso Tool (L) while holding (Shift) button make a selection where the left side is at 45 degree angle, rest of the selection doesn't matter.. just make it big enough so that you have something to era.. Try to make a selection that is about 45 degrees and because you are holding shift, the selection will be exactly 45 degrees.
5. Fill that with white color and Deselect (Ctrl+D)
6. Use Eraser Tool (E) With Soft round brush of different sizes to soften out the right side of that white area ( watch out for the left side.. but in some cases you might want to go over it a little bit to make the edge tad uneven.. )
7. Apply Blend mode: Overlay to the layer and replicate everything starting from 4. a few times.
8. After you have done a few more that are slightly different Duplicate these layers one by one (Ctrl+J) and move with Move Tool (V) while holding (Shift) if necessary..
9. After that I basically just copied the whole Group ( right click and Duplicate ) and moved the position of those white highlights and gave the group below a lower opacity
10. Some extra stuff I selected every layer minus background with (Ctrl or Shift) and merged them into a new layer (Ctrl+Alt+E). Then gave it Filter > Sketch > Chrome and after that gave it Blend mode: Screen and lowered the opacity just a little.
11. Then I selected everything once again.. ( minus the same things ) and merged them into a new layer just like before. Then Edit > Transform > Flip Vertical and moved it below my original text in the document and used Eraser Tool with soft round brush again to erase the bottom part of the text.
12. Theen I made a new layer and in it a white rectangle and used Filter > Blur > Gaussian Blur.. in it and gave it the Blend mode: Overlay and copied it once (Ctrl+J)
13. Theeen I made the sparkles and swoosh swoosh...
