Hi Rally- did darks bias and flats-= loaded them using calibration wizard so they are all in the programme as individual files- so I assume it creates masters off the bat first but has left the original files still intact, there is a button to press to use masters but I didn't check this as I was thiking about adding some further calibrations frames later.
I usually keep originals - but for some reason I decided to to tick yes for all and not no for all - maybe as I had a lot frames and it took so long to calibrate. Bummer - there goes 3 nights work!!
