Your referring to Quick mode in the Photoshop Elements 2026 Editor?

It’s in Adobe Camera Raw.   Click on the square icon near the bottom right corner.  It should be the first icon the far right of the visible star rating.    The forum isn’t allowing image uploads right now, sorry. 

When I was creating  the original post I l kept getting error messages about waiting for a file to upload, so I closed that post, and started another one.

I did that few times while trying out different things to see if I still got the error message.

The response from below is 3 years old- but still applies.

Many users in the past have used the history (F10) panel to view what they started with- and many say using it is quicker than a before/after side by side comparison. 

 

There could by any number of reasons why it’s not a clearcut option in PSE, however, I think it may be simply because not too many people use it.
