Making HDRI maps smaller

I use a lot of HDRI's from Poly Haven but they are so big that it looks like the trees in my imges huge. Sort how DimensionTheroy looks. Can you resize them? Do somekind of adjustment of the dome?

I hop I explained this right.

    You can use Photoshop CS5 or newer, HDRShop if you have it (not available anymore), Picturenaut (free), actually any graphics program that can read and write .hdr files.

    Unless I'm not understamding your question, the dimensions of the file in pixels is not what you're concerned about. A given tree will appear bigger in the render if the camera is zoomed in more, so zoom out your camera view. 

    HTH.

    That's the way I was reading the OP too. I have yet to find a way to adjust for relative size of the objects in the HDR image compared to the people, etc., I put in the scenes. So I often choose those HDRi pictures at PolyHaven in which the trees are way off in the distance, or I turn off the image in the render and just use the HDR for lighting and add a backdrop image on a plane primitive. Either way is not ideal. 

    I've bought a few of the Dimension Theory HDRs but now avoid them because they mess up my render/camera/light settings.
