Hi;
in my workflow (interior scene)
1- I save the image in .cxr format
2- apply lightmix + postprocess set for interior (hdri, sun, sky...etc.) and save
3- I apply lightmix + postprocess set for outdoors (with low exposure)
4- postproduction in photoshop and I combine the two images
if it were possible to exclude the lighting, for example hdri, from the nature outside the windows, from 4 steps we pass to 1.
This is for my way of working of course :))
In general, the option of exclusion or inclusion in the corona lights is perfect and very flexible; especially for backlit images
thanks, Matteo
