Whether it’s something you sketched, rendered, or photographed, once you’ve got an image in Fenestra, you can do a lot with it. One of my favourite things to test is different environments - rain, snow, sunset, night, or even full-on lightning storms.
If you’ve got existing renderings from a project, why not try a new time of the year?
Great if you’re telling the story of how the project may age or be experienced over time.
Start with a Base Image
Upload your image into Fenestra - or quickly generate something with Sketch To Render. In this example I started with a sketch of a modern villa and then used the generated image as a way to transform the existing time of day, season and environment.
Enter Edit Mode
Select The Conversational Edit Preset
Keep your prompts simple here are a few I’ve used:
- “Make It Snow“
- “Change to evening with the lights on inside“
- “Film photograph, dark atmosphere, night-time storm“
- “Morning sun, morning dew, long ambient shadows. Crisp atmosphere.“
The simplest of prompts go a long long way, the context is in your input image, provide it with a good high quality image. If you don’t have one, generate one from your base sketch, 3D screenshot or anything you have on hand.
Pro tip: Use the Conversational Edit workflow to create your image just tell it what you want (it does more than edit)
Try a few prompt variations to explore times of day and environments.
Awesome. The captions for the images are the types of prompts i’m using to create each image - give them a try yourself in Fenestra.
