Open the image you want to put the text on. Feel free to download this bottle image. Make a new layer, name it bump, fill it with white and move it below the bottle layer.

Image

Foreground color black, click the Text tool. Write the text you want on the bottle and size it and position it over the bottle image where you want it. The grapes are a dingbat in a font named FOOD!. I browsed daFont and wrote 'food' in the search box and the font I have isn't there, however this font has grapes I like much better. Since I already had a finished bottle I didn't want to re-do it. I recommend this font for the grapes. Here is part of the bottle with those grapes bump mapped onto it.

Image

If you are adding a dingbat, click the bottle layer and then the Text tool and add the dingbat. The text and the dingbat will be on two separate layers. After you have them positioned where you want them merge the text and dingbat layers (DO NOT merge to the bottle).

Image

Move the text/dingbat layer below the bottle and merge it to the white bump layer. Select the bottle layer.

Filters > Map > Bump Map

In the dropdown at the top of the Bump Map dialog, choose the bump layer.

Experiment with the settings. The settings in the Bump Map screen are the ones I used. Inverting makes the darker shadow area fall below the text.

Image

After you have adjusted the settings to how you want them, click the OK button. Delete the bump layer.

This method can be used on other surfaces. Check out the discussion in this thread for more ideas.

Here is a beer bottle using the same technique.

That's cool, I don't know how you thought that up. :)

I have an idea. What it you made a bi-linear gradient on it's own layer and set it to Overlay or something to make the effect look more cylindrical?

I'm not sure what you mean, Demen. Could you give us a demo?

Wow, Greg. That looks so real. You got a great "do" on that bump mapping and also the gimp chat circle text.

Thanks Oregonian, for your comments. Your tutorial is very straight forward and easy to follow! Excellent job!

The font I used in the Text Circle is one called Kredit, and it lends itself very well to bump mapping. I think I got it from DaFont.com.

Just a quick example:

Also, I curved the text by using the Shear Tool in various places.

Nice suggestion Demen. It does make the bottle and text look more curved. :geek

Here are the two images for comparison. My original on the left. Demen's suggestion on the right.

I did the original (left) and Demen's gradient added (right). I then redid Demen's idea with FG to Transparent gradient (center) with Opacity set to taste. I also experimented with different layer modes (not pictured here). There are so many awesome results to be had!

I really like the transparent gradient the best, Greg. Totally great idea there - makes the glass look glassier. Things are blooming in here. :hehe

Oh yeah, keep in mind you can use the Scale Tool to squish the sides (leave the center alone, select left side, squish it, select right side, squish it) to give the effect that something is wrapping around a cylinder that's level with your eyes. You might have to reposition each one after scaling, but this technique usually works.

I didn't think of that Demen! Another variable to play with!

I never thought of using bump map that way, now I'm torn between being mad at myself for not thinking of it and awestruck at the possibilities. Either way thanks for posting this, I'll try to make good use of it.
