Render with Perspective View vs Render with Camera

Render with Perspective View vs Render with Camera -

so I set the rendering to Sun-Sky 1:00 York, England indoors with windows as part of one of the modern contemporary freebie sets and I set the EV in the tone mapping settings to 7.

I then render with camera and for a long time it renders (over 14 minutes) unti it finally writes but it is black except for a pixel or two of light (probably the emmisive candle flame at 250 watts) so then I cancel & instead render with Perspecitive View & hide the Camera. No I get a render iteration written in about 5 minutes with a glowing light around the candle flame like I expect.

How do I set up my iRay Rendering settings so that the camera acts like Perspective View Rendering mostly? I've already set the Exposure Value from 13 to 7. Do I need to change the gamme from 2.2 to 1.0? I am CPU rendering.

Thanks.

    Are you sure the camera view isn't blocked? EV shouldn't matter between the two.

    Well, I'm right a a wall and couldn't see through, so I scroll a tiny bit more closer & then I can see what I want to render except the Camera is black rendered and the Perspective is as expected. I will double check those...

    What does one do when the wall is blocking the view but you want the camera to see through the wall/door?

    Iray Section Plane comes to mind, assuming that you can't remove the wall/door/camera.

    I'm note sure what's going on for you. If I understand the issue, I tried two tests.

    Left shot has the camera focused on the plane. Middle shot, I zoomed the camera by scrolling mouse, right shot is screencap of the viewport to show the setup

    In both cases, the render matches what I see in the Viewport.

    I don't think I have more to offer, sorry.

    Thanks.

    How do you setup an iRay Section Plane? I looked in the camera settings and I didn't see a mention of it.

    Also, I'm not sure what was happening yesterday morning but be the evening the rendering with the camera was acting normal again.
