Losing Information in Photoshop

The message is new, but it’s confusing because the wording is vague and doesn’t offer a solution.

It’s trying to warn about when, for example, someone started by opening a JPEG file and then added all kinds of Photoshop features that can’t be preserved when saving as a JPEG file again, like a lot of the things D Fosse mentioned. That part is nothing new. But I think in this release Adobe was trying to explain why Photoshop wants extra steps when saving what was originally a JPEG but now needs to be saved as a Photoshop (PSD), Photoshop Large Document (PSB), or TIFF file to preserve all of the features used.

Since the latest update, each time I go to export my file, I'm told that if I export it as a jpeg, I will lose information. This happens whenever I open the export window.

The word “export” is used there, but are you sure that it happens when you specifically use a command on the File > Export submenu, such as Export As or Save for Web? Because I only notice the alert message when using the File > Save or File > Save As commands, that’s where Adobe wants to warn people away from saving an original as JPEG when it contains non-JPEG features. 

In other words, it shouldn’t warn when truly exporting, it should warn only when using the Save As or Save commands with non-JPEG features.

That also points to one workaround. To avoid the message, use a command on the File > Export submenu because those always create a copy that doesn’t overwrite the original. Or, if you want to preserve Photoshop layers, transparency, Smart Objects, etc., save as PSD, PSB, or TIFF format.

But again, I think their alert message wording is unhelpful and they need to edit it so that people know what to do.
