How do I widen the image of my render?

I have a camera that is close to the subject. But I want to widen the image to include more of the scene in the rendered image.
Ordinarily, I would simply back the camera up to get more of the scene. But if I back the camera up, I end up on the other side of a wall. So I can't do that.
So how do I get the equivalent of backing up, without actually backing up?
Please do not gove me an answer in terms of alanogies to what a photographer would do. I do not not anything about the camera settings that real photographers use. I don't know what fstop, depth of field and so on mean. Of course, the sliders that control Daz cameras have these names (fstop and so on), so I do expect to be told to adjust these sliders. That's fine. I just need someone to tell me what setting to apply, what sliders to asjust, without having to get a PHD in photography.

Learning basic photography is not difficult and does not require a PHD. The issue you have is called Focal Length . "A camera’s focal length is usually expressed in millimeters. The Focal Length slider allows you to zoom in and out of your scene without moving the camera. This is useful when, for instance, you want a wider angle within a small space in your scene."
I highly recommend you read up on using the camera in the Daz Docs http://docs.daz3d.com/doku.php/artzone/pub/software/dazstudio/reference/vc_camparams
It's very sinple. No PHD required. I'll explin this as basic as I can.
Frame Width gives you a wider shot of your scene. Which is what you want from the sounds of it
Focal Length has a similar effect with more Lense distortion.
Depth of Field is basicly Camera "Focus" Which often blurs the background and foreground.
F/Stop Basicly controls how much of the scene is in Focus when using the Depth of Field Effect.
F/Stop (Focus Stop)
In Iray you can also use a Section Palne (Create>New Iray Section Plane) to make the stuff on one sde of the plane invisible, which lets you put the camera on the wrong sdie of the wall. I advise turning on Clip Lights in the parameters for the Section plane, otherwise light will come through the hole and reflections will not show the hidden mesh - which is apt to spoil the image.
I've tired that before but I didnt know how to assighn the selection Plane to a particulare wall or surface.
Or am I using it all wrong?
You don’t assign it or parent it. You simply create it and position it in the scene, and it cuts off everything on one side of it. (Positive Y, as I recall.) You won’t see the effect until you render, or else change the viewport to iRay mode.
Just gave this a whack, and apparently all you have to do is move and rotate it into position. It's an Infinite Plane, and does not have to be resized to cover anything. It also cannot be resized to make it only affect a small section - it's all or nothing.
It does have a front and back. Everything in front of it is visible, everything behind it is invisible.
The plane can only be loaded in as facing Up, unlike Primitives where you can specify the starting rotation, so if you drop it into a scene with a house, the house will be invisible. Raise the plane or Rotate it on the X or Z axes, and it will reveal parts of the house. Rotate +90 on the X and you can use it to hide walls.
Oh Alright I get you. So what I did was parent it to a Zero'd out camera. Then Saved it as a Scene Subset.
