Below is a glimpse of the process I used to create a digital render of my aunt's family home.
These are drawn in Illustrator as a framework for everything else.
Shadows and texture are added to the house. A backdrop image of blue sky is added as well.
The shapes of plants are added. Few colors are used at this stage for simplicity's sake.
Texture is added to the road and minor flaws are fixed.
Lighting is rendered in Photoshop and more minor tweaks, such as plant pot colors, are made.
Flaws, errors, and weird spots are Photoshopped out and a tilt shift is added to suggest depth of field.
