Only 30 min? Without denoising?
Is the background behind the window a HDRI or a image plane or it is added in postpro? I have always a trouble with windows, they are too overexposure or too vibrant. Also I see that view behind the window is blurred so it is a HDRI blurred or it is bluring achieved with depth of field?
@ArcHWiZ are using fSpy for Camera calibration for exact IKEA cameras? If so can you teach for some trick on how to exact use? Note: i saw already some tuts for fSpy on YouTube but without success.
