Drawing effects with the Specular Method. Three BTO trees lit exclusively with specular from the WhiteSphere HDRI. Above as Pencil Sketch (monochrome), below coloured with coloured Specular, the HDRI mixed with the sky colour. The labels on the pots (from the Vegetation set available at Daz 3D) were made in Elefont. Pure Bryce renders, no post work.
