Lots of things to experiment (play) with on the MacBook now. One such is the Mac app 'Simply HDR'. It is not what I would call an HDR program, more an arty manipulation app which works on a single photo but with many effects to choose from.
I started with a dull photo of the artificial bird of prey I had taken recently ......
...... cropped to remove the telephone cable and then adjusted by choosing HDR HDR-12 with adjustments to grain strength, smoothing and vignette:
To me this made a much more dramatic and interesting view from what was a photo I would probably have binned.
