Too zoomed in...

jaxprog

If I put an image in the Iray envirnoment map, on the Render Settings tab, and when I render the image it appears too zoomed in; how I can unzoom so that the render can show most of the image. For example, lets say I have the enviornment map point to an image with three trees in row. Instead showing all three trees it zooms on one branch of the middle tree. What controls are there to unzoom it?

Thank you in advance and I appreciate your time.

I lower the dome scale multiplier to about 10 (you see it if it's set to finite dome).  I'm not sure if that's the correct thing to do though.
