HDRI & Scene Newbie
-
I am a newbie to HDRI lighting. What I need is to render a lot of interior office furniture scenes. And I need them to have HDRI lighting, with the scene outside the window to match. See the attachment as an example.
I see lots of HDRI lighting tutorials, but not a whole heck of a lot on how to put a realistic scene to match. But again, I'm a newbie, so hopefully you guys can point me in the right direction of tutorials, videos, or general tips. Thank you!

I believe it's mostly about understanding where light comes from (its color/tint as well) your background image and try to match that. Then tweak in post process (color corrections etc.).
I can suggest checking this tutorial for post-processing with channels and lossless adjusting (16/32 bit image) if you haven't already.

lol, that's not my render. That's just a photo. What I'm saying is, I need to know how to do something similar. Not only have the light of the city scene, but actually have that city scene outside the window like that.

Ahah, allright then. (Advises on my first post are still relevant though)
When you said you watched HDR tutorials, i assumed you already know dome lights, spherical images (preferably HDR), rotating them etc., do you?Briefly:
1- Create dome light anywhere in scene.
2- Apply spherical HDR image (that cityscape in your example) to dome light.
3- Rotate image & tweak settings that suits your needs.
4- Render!
That background scene is -probably- a spherical HDR (High-Dynamic-Range) image. Dome light takes color information from the HDR image and illuminates the scene accordingly. So you have an accurate image-based lighting environment.
Thus the most important step becomes to be able to find good quality HDR image that you desire (check these free ones).Note that not all spherical images are HDR. You might find spherical .jpg images while searching which will not be carrying any light information and will act just like a background image.

Gotcha. That certainly helps. So in the example of my picture, is there a way to position HDRI other than rotate it around? I'd like the same effect, where it's floor to ceiling windows. But seems no matter what I do, to get an angle like above, I catch a huge chunk of the ground before it hits the HDRI image on the horizon. I tried elevating my room but that didn't seem to help (see my image). How would you go about getting the effect in my first post from a positioning standpoint? Thanks for the help.

Make sure you ticked the 'Spherical' option. So that image wraps around and you won't see plain ground.
And i think your only option is rotating (i might be wrong). But making changes other than rotating doesn't make sense, because it'll shift the horizon etc.
