Here It Comes Again

Nikon D40 + AF-S VR Zoom-Nikkor 70-300mm f/4.5-5.6G IF-ED lens at 300mm. The full frame equivalent would be using a lens of 450mm focal length. The effect is to make the perspective appear compressed and packed up. Had I taken this photograph with a wide angle lens instead it would have appeared quite different but the perspective would not have altered.
Curiously Bob Newman, who is Professor of Computer Science at the University of Wolverhampton, and a photography enthusiast, camera nut, and regular contributor to the magazine 'Amateur Photographer' ('AP') took a more liberal attitude to perspective in 'AP' of 24 August 2019. But think about it: perspective can depend only on where the viewer is and where the thing being viewed is.
