A couple of years ago, I found the technique on Luminous Landscape for exposure blending in Photoshop using layers and gaussian blur.
Just lately, I've been getting into cathedrals and trying to capture them without that overprocessed HDR look.
Here is Nevers cathedral in Burgundy. It is two images blended together. The majority of it is one image and one exposure. The windows are from another exposure.
So, as I say in the title. Thanks to the LL site for publishing the technique. It beats HDR hands down
