We will start out by showing how to create the "Bumpy Log" texture effect, beginning with the drawing shown below. (Click any image for a larger view.) The clearer your drawing is and the sharper the line is, the better your texture will come out.
1.Open Photoshop and import your log line drawing. Click on the drawing with the "Magic Wand" tool. If you find that you don't have the entire area selected, you can choose to increase the tolerance field number on the top tool bar. Type "35" for your tolerance level. Now click back on the log and select it.
2.Hold down the "Shift" key and select to make your selection grow. We need to add a color. Click on the "Paint Bucket" tool and select the "Foreground Color" icon. When the Color Picker dialog box is open, select the color of your choice. In our case we will select a sandy brown. Click OK.
Select the log and fill in the color in its totality. Now let's add the texture with the log still selected. Go to Filters > Textures > Mosaic Tiles. Slide the "Tile Size" to "9' then make sure "Grout Width" is set to "2" and keep "Lighter Grout" set at "4". Click OK.
3.You now should have the beginning application of the desired texture. Let's go for detail. Go to "Filter Stylize Emboss". Make sure the angle is set to 135, height is 9 pixels, and amount is 100 percent. Click OK. The log should look like the image below.
