Hola folks. newb here, so pardon the smell.

Im trying to figure out if theres a way to alter the perspective of shots i create with poser, to exagerate the perspective and create a super forshortened effect. But, i have no clue how to do this. i've fiddled with the perspective and focal length sliders in the camera parameters box, but that doesnt seem to produce any changes in the rendered image. any help with this would be greatly appriciated.

thanks!

Select camera under properties adjust focal length and Z trans

Erm...would you mind breaking that down a bit for me? when i select the main camera, i can alter its parameters and properties. theres a slider under parameters that is labeled "focal," which i assume controlls focal length, and benieth that there is another one labled "perspective" which changels along with anything i do to focal. under parameters i cant seem to find any controlls like what you mention. my only options are click boxes labled "visable, animated and remember changes to undo"

when i mess with the perspective and focal length sliders, nothing seems to happen, either in the preveiw window or in a render.

sorry for being a bit thick, im new at this.

Edit: well thats odd. all the sudden those sliders started working. no idea why it was giving me trouble before. oh well, thanks for the help!

I did a tutorial on Poser scene handling, including camera details.

Start here: http://www.book.artbeeweb.nl/?p=3065 and take the camera route. Enjoy!

You're changing the focal length of one camera while looking though another camera.

You never mentioned which camera you're looking through so it is indicative that you have no idea that more than one exists.

Inside the upper left corner of the preview window, it will say which camera you're looking through: Main, Aux, Dolly, etc.

Just above that is the actor selection menu - the selected actor is the one you're manipulating in the parameters. If these two things are not the same, you will think the parameter dials do nothing.

There are numerous ways to select different cameras for looking through, but the most general is to right-click on the preview window, select camera view, then choose a camera.

Hot keys for a couple exist: Ctrl-M for main.

Just a quick note about perspective: changing focal length does not change perspective (only the angle of view), you must move the camera. To get the exaggerated effect you want you must move the camera very close to the subject and use a very wide angle of view (set focal length to 16mm or thereabouts), like you'd do with a real camera.

One last thing to point out... The "Parameters" tab is where you will find the controls and dials to adjust things. "Properties" is where you will find the option boxes you will click to selection. Not the other way 'round. Just so you know.

Yes and there is a parameter dial called perspective that both changes camera position and focal length at the same time. OP said he tried that and it did nothing.

I don't believe it was done to the correct camera. It is super obvious that it does something when you actually do it to the camera you're looking through. 

Oh sorry

parameters not properties
