something that bothered me for a while while modeling in lw was the perspective amount at which to model at well i found some report that has finaly put my qestion to rest the humnan eye see at apoximly 36 degrees i just thought that this may help some of you out or you might find it interesting

I once posted some viewing angle figures for 35mm camera lenses (on the Wings forum) - but can't find them :) A 50mm 'standard' lens (one that used to come with the (SLR) camera - in previous days) has a (diagonal) viewing angle of 46 deg. This was supposed to give a view similar to that perceived by the eye. More recently, a 35mm lens has become more 'popular' - view angle for this is 63 deg. (Typical focal lengths for taking 'portraits' are 85mm - 100mm - with corresponding view angles of 28.5 and 24 deg respectively) Depending on what's being modelled, it might be worth messing around a bit? :) (Lens details from Canon EF series, btw) pp

Funnily enough I started messing with the view angle of the modelling camera in wings today. It struck me that it was a bit wide angle so I narrowed the view quite a bit (down to 15 degrees) and it does feel better for modelling but when I rendered it changed the view. I've no idea why and haven't experimented further yet. If I figure it out I'll post, but I'm using an old version, this may be something that has been fixed in more recent versions! Baz

There is no correct focal setting :) For some people this is an issue, I model with perspective turned on, some people with it off (In Lightwave)... a lot of gray shades in between. Set the focal setting for your modelling app to match your renderer. It's really a personal preference :D

Here's a quick comparison I did of different lens focal lengths, using a Poser figure in Cinema 4D. Cinema's default lens is 35mm; not always the best, especially for human closeups. From this test, you can see why 85mm is considered a portrait lens.
