GIMP: Lamp tutorial

This tutorial will create a desk with a lamp on it. To the lamp we'll add some light effects.
Final result:

1. Fire up GIMP and create a new document. Make it 800x600 pixels large.

2. Create a new layer and name it Wall. Do this by pressing the New Layer icon in your layers dialog (A paper with an orange symbol on it).
Make sure the layer Fill Type is set to Transparent.

3. Create another layer and call it Chest Draw, this layer should also be transparent.

4. Grab the Rectangle Selection Tool from your Toolbox and draw a rectangle in the lower right corner. This is going to be the base of the table. A simple cube with a couple of drawers in it. Mine is 110x455 pixels big, you can easily change the size of it by dragging a corner of the selection or tpye numbers in the Rectangle Select dialog in your Toolbox.

5. Fill it with this color: #363432. (First, click on the top color box in your Toolbox and then in the HTML notation text field paste the numbers.

6. In your main menu, go Select->Shrink and shrink your selection with five pixels.
Fill this selection with this color: #727272.

7. Shrink the selection 5 pixels again. Go Edit->Stroke Selection in the main menu and make a 1px stroke with the color #363432.

8. Select the Rectangle Selection tool from your Toolbox, click on your selection to make it active. In the tool's dialog, make the size 88x41 pixels big, repeat the stroke.

9. Move down the selection 40 pixels (making the position 702, 506 if you have followed my directions). Now you have three drawers, but with no knobs. Draw a small rectangle in the upper middle section of one drawer and fill it with: #363432. Do the same to the other two.

10. Now duplicate the layer and place it more to the left, almost in the center of the document. Create a new layer and name it Table Board. Make a thin rectangle that connects the both drawers. Your document should look something like this now:

11. Create a new layer and name it Lamp Base. Again, grab the Rectangle Selection Tool. Create a small rectangle above the left Chest Draw, on top of the Table. I made mine 46x16 pixels big.

12. Duplicate the three Table layers and merge them together. Do this by duplicating them and place them next to each other and mark the top layer, then go Layer->Merge Down a couple of times.

13. Right click the Table Shadow layer and choose Alpha To Selection then click the Delete button on your keyboard. Go Selection->Feather and feather the selection by 8 pixels. Set your foreground color to black and grab your gradient tool. Select Radial as gradient shape and FG to Transparent as gradient Type. Now make a quite big gradient starting from the center of yur selection ednding 50-60 pixels outside of it. Place the Table Shadow layer beneath all other table layers and move the layer a couple of pixels south-east. Now your table should have a drop shadow!

14. Create a new layer and name it Lamp Base. Create a 42x21 pixels large cube on top of your desk. Fill the selection with a wood pattern, I chosed the "Pine?". Select the Ellipe Selection Tool and make a seleciton that covers everything of your lamp base except for the two top corners (my selection is 60x60, a tip is to press and hold down SHIFT while dragging), invert the selection by right-clicking on it and choose Invert. Then press Delete.

15. Create a much thinner but higher rectangle on top of your last one. this one should be 5x57 pixels big.
Fill this with the same pattern. Also make a tiny, tiny one again, this time at the top of the thin one. This is going to be the piece that holds the Lamp in place.

16. Create a new layer and name it Lamp. Create a circle, mine is 63x62 pixels big. Grab the gradient tool and make a FG to Transparent, radial gradient with the color: #403d32. Make it quite big so you'll manage to fill the selection.

17. Copy the Lamp Base layer and name it Lamp Shadow. Do the same as in the Table Shadow steps (13). But this time feather the layer only 5 pixels and use the color #b1a36a in your gradient. Don't forget to put it just above your Table Shadow layer.

18. Select the Wall layer and fill it with the color. #474d41. Then grab the Gradient Tool once again. Set the Foreground color to #f0e4b2 and Background color to #474d41. Then look at the gradient settings. The Mode should be set to Soft Light, gradient type to FG to BG and shape to radial.

19. Create the gradient, starting from the center of the lamp and ending almost in the upper right corner.
Now you are done!
