Based on the available reference, adding rock texture in Photoshop involves using filters and channels. Here's a general outline of the process:
- Create a New Channel: Open your image in Photoshop. Go to the "Windows" menu and select "Channels". Create a new channel.
- Apply Render Filter: With the new channel selected, go to the "Filter" menu, then "Render". Experiment with filters like "Clouds" or "Fibers" (the reference is cut off, so specific filter choice is not definitively stated).
- Adjust as Needed: After applying the filter, you might need to adjust the levels or contrast of the channel to refine the texture.
- Use the Channel as a Selection or Mask: This channel can then be used as a selection or mask to apply color, shading, or other effects to create the rock texture on your image.
This is a simplified explanation because the provided reference is incomplete. More specific instructions would depend on the desired look of the rock texture and the image you're working with.
