HDR Image composition

We have a HDR function that is very useful to recover detail from bright areas etc. However, how about a utility to actually create a HDR image using 3 or more non-linear images with functionality similar to this: http://qtpfsgui.sourceforge.net/

While this software could be used it would be nice to integrate something in Startools more elegantly withinin the Layer module that performs proper HDR processing usinsg various algorithms on the images...

No idea if this could be used in linear state, and in any case that is likely getting closer to what HDR already achieves, nut for non-linear its a different ability all together.

It's a 7-year old video (and YT has removed all the annotations since), but is this what you're after?

E.g. it creates a HDR composite from two images. Three or more just require repetition of the output with the third, fourth or n-th image.
You can use the Max Contrast filter or (usually preferred as it is quicker) the Min Distance to 1/2 unity filter for this.

Its close I guess. But it would be nice to have a actual module to do this rather than try and find a way with tools. ST can do so much but some of it would be easier with a predefined module...
