thanks
ok, here we go:
1. How to get the wet look on the pages which you have probably noticed from the original...
use a soft brush, blending modes, opacity, maybe some doge, burn or sponge, some gaussian blur, just play and fiddle. to get wet edges (B), select "wet edges" in the brush palette
2. What should I do to simulate multiple pages?
Should I just copy the layers and the rearrange them?
different ways to do it. in my example (C) i used stroked paths
3. How to build the look, where both pages of the book come together (the middle part of the book?
the effect is exaggerated in the following example to show you in detail how it works
select the left half of the book (D), add a clipping layer and use a linear gradient to create the left side of the center of the book. then select the right side of the book and do the opposite. take a soft white brush (new clipping layer again) and pull down from the left edge downwards (hold down the shift key); adjust opacity and blending mode. do the same with the right side, this time with a dark brush, which I forgot to show in my attachment (depends all on where your light will be coming from)
To get a curved page (E); rotate the book, select the upper part and add shear (filter, distort, shear). do the same with the lower part.
the text... use the distort perspective tool first to distort the selection, rasterize layer and use the liquify tool to distort it even more. be careful not to blur the text too much. sharpen the text slightly when youre done. other way to do it; type a text in Illustrator (A), ungroup and move or deform the text using the deform tools (lot of work though).
and then there are thousands of other ways to do all this?but that?s exactly the fun of photoshop; no limits!
