This image was made using a Sony A7RIV and a Canon 17mm TSE.
I used Lumipro strobes to light each wall in separate shots, as well as the island and ceiling. Lights were bounced off the ceiling to create even and soft lighting.
Raw files were processed using Raw Therapee, then in Photoshop I combined pieces from each of the shots like a collage to make an image that looks like a cohesive single exposure.
No HDR was used, and the views through the windows were balanced for exposure with the interior using lighting on the interior, and so are real and were not edited in.
