So, here is my starting point for this figure. I will often set my sketch layer to multiply and then colorize it with an additional adjustment layer.
I went over my process for rendering these cell bodies and extensions in an earlier post so I am just focusing on the surrounding bone matrix here. In this image, I have:
- darkened the channels to make them look like tunnels
- added a rim of shadow to one side of each tunnel
- added a rim of light to the corresponding hill that a tunnel cuts through or surrounds
- added some subtle embossing effects to produce the texture on the hills
These blue osteocytes sit inside fluid filled channels. The cell bodies and the processes are covered. So to indicate that:
- I did a flat fill in the tunnels on a separate layer. (This indicated the liquid.)
- I set that layer's transparency to high.
- In a new layer, I added highlights on either side of the furrow to indicate the viscosity and reflective nature of the fluid.
Lastly, to indicate that the cell bodies themselves are also covered in fluid, I extended the highlights on the processes onto the cell bodies.
Below is the final illustration with labels. I painted a haze behind the labels to increase the contrast between the text and the figure.
That is it for this week's post! Thanks for looking. Feel free to like or share if you found this helpful!
