Well again, I re-downloaded the app and reinstalled it. Now it's working fine. Phew!

I know this sounds most improbable:

When I shoot a stack with HR, there is a live view on screen, the focus is moves, the shutter clicks--but there is no data present. I don't get the prompt "do you want to open the images in HF?", and if I do open HF there is nothing there. Clearly HR is talking ...

Somehow I seem to have downloaded a beta version of HF. Ver 6.3.2 actual solves the issues I've been raising.

Thanks for your patience.

I saved a stacked image as TIFF and when went to read it in PS got the error message.

"Could not complete your request because the file-format module cannot parse the file"

Should note that the file stacked from five 36 Mb DNG images saved as a 216 Mb. That just doesn't seem to make sense.

Any ...
