Photometry and narrow band astrophotography are areas I am taking up this year and Pixinsight is a program I will be acquiring. I would be keen to know if routines such as background neutralisation and curves transformation modify the background data or just the way its presented on the output device (screen or printer).
As Rick said. But don't worry about losing your original data. There are multiple ways of avoiding this. Also, you can preview the effect of most processes before making the real change.
