Do .psd files have any stored metadata about historial of editions performed on them?

[Guest]

I edited a long time ago a .psd file, changing its brightenss, contrast, color balance, etc. Now I need to retouch some other pics that have the same darkness/dull color conditions in order to get exactly the same improvement effect than with the old one, but I don't remember what amount of color, brightness,contrast I did change, (in terms of parameters). What can I do? Is there a way to explore inside the .psd files to see what parameters change from one to another?. I still keep the original and the retouched version of the old pic, if that helps.... Thanks.

If you set up the History log in Preferences like in the screenshot below, you will get a detailed description of your edits as metadata.

Whether or not you have any metadata for this particular file will depend on how the history log was set up before you started editing the file.

Thank you for the answer, i did not know that option. If I would....

Unfortunately, the psd file in question did not get the History Log option set up before the edition.
