  3. On the new layer, you will need to create white areas were you would like subtle positive texture and black areas were you would like flat texture. Gray tones will produce intermediate texture results.
  4. Follow Photoshop 1.1 [black & white] to create a black and white image from your original texture image.
  5. Follow Photoshop 1.2 [levels] to adjust the levels of your image. You should exaggerate this adjustment to create a true white and a true black.[Premium Content - Login] [Membership Options]

  6. If the white pieces of your image are not the pieces you want to be sticking out, click on your primary layer and then navigate to Image>Adjustments>Invert. The blacks and whites of your image will be reversed.
  7. Navigate to Layer>Merge Visible to make a single layer from your primary layer and your adjustment layers.
  8. Use the Filter>Blur>Gaussian Blur... filter with a 1.0 pixel radius to slightly blur your black and white bump map. This will result in better mapping.
  9. Use File>Save As... and add “_bump” to the file name. Please save your texture and your bump map in a “textures” folder on your flash drive. You will need these files later.
