I'm new to Blender and this is my first big project.
What I have: multiple objects (table and chairs) built using given dimensions to represent the interior of a dining room.
What I want: to arrange these objects and the camera so that they match the perspective of a photo of the real life scene.
What I've tried: I've added the real photo as a background image for the camera view for starters. I also drew some guide lines onto the image to get an idea of the where the perspective line lies. Many guides exist but these seem to nearly all revolve around building objects from scratch onto the background - matching objects to camera rather than camera to objects. I've spent hours rotating and zooming and tilting the camera and I can't seem to get close at all. I know manipulation of the shifts and focal length come into play but I've tried adjusting these and I have no idea whether I was making things better or worse
Here's the closest I've come, I've just been focusing on aligning the table as it's the central piece. You can still see the end of the real table sticking out and the furthest legs won't align, but the dimensions should be accurate.
I'd really appreciate some help or guidance!
