Is there anyway to retain the Metadata when saving a file from .PSD to .PNG? I get a warning saying the file has to be saved as a copy, and then metadata is gone.
i remember that i have read "save for web" will save the metadata into PNG.. but PS will not read the metadata.. but bridge does.
im not sure if that is correct.. i avoid using PNG.
Adobe Photoshop engineers have commented on this over the years.
PNG is not viewed by Adobe as a working format, just an end-product or final-output format.
PSD files support layers and more metadata than PNG.
PNG is not a working format, but something you export to when you're done with all your edits, similar to JPEG or GIF.
Unfortunately, PNG has only minimal (and confused) metadata standards.
You can tag it within an application, but the application doesn't have a standard way of putting the metadata into the file.
There will be more hits if you do a forum search and add Chris Cox as keywords to your PNG metadata search.
A thing to remember is that web sites very often will convert PNGs to JPEGs and do it very badly, beside stripping metadata.
