Unlike a real In-Person Twilight session, the Virtual Twilight session consists of daytime exterior shots that we edit in post-production to appear as though they were taken in the evening. Simply put, we shoot the property like a normal daytime shoot (no additional time on scene), and we make an evening version out of 2 or 3 of the main exterior images.
While not as good as the In-Person Twilight (in terms of authenticity), it is a cheaper option and allows for more flexibility with scheduling.
The only thing to be mindful of is that this works with a simple house and some basic landscaping. It is NOT a good solution for properties that feature a view, as filling in tens of thousands of lights in a city is just too much to pull off and have it look anywhere near authentic.
