viewpoint help - how to simulate accurate viewpoints

[simonm]

Hi all

 

I have a friend who needs a favour and wants me to provide 4 rendered images of a site complex at 4 key points. The point of this exercise is for them to visualise the project from these key points to see whether you can see the solar panels or not which are placed on the roofs. There are 22 homes in total and all will have the solar panels on the roof.

 

Im thinking of placing the cameras at 1600mm above the street level, but in terms of the camera focal length, should i leave it at the default or any particular value? I mean, i dont want to warp the image by using a very wide angle and it needs to be represented accurately if you know what i mean.

 

how would you tackle this?

 

Thanks

i believe technically human eye have a field of view similar to a 20mm camera, but the periphery is so blurred and warped that our perception of the view is closer to a 50mm.

Focal length won't affect whether or not you see the solar panels. 50mm lens is standard used for situations like this where you are demonstrating a human perspective, but if you need to widen to capture the whole scene it won't be any less accurate.

While technically 50mm is the most correct I usually use around 35mm.. 50 just seems to be too 'zoomed in'
