cannot save a picture after changing

[yaacovk]

Hello.
i have a 2.10.30 ver. on windows 11.


i opened a tif file photo for set it up.
after i made the changes i wanted to save it in the original file type (as a tif file)
i choosed the "Export As".. and replace the original photo.
after made this action i saw that the photo didn't changed as i made.
can someone explaine how to save it for change in correct process?


Thanks in advance.
