PS19 process to grab four corners of an image to square up the margins

Hi. I need to adjust the perspective on photos I took of pages of a book (in this case, a family scrapbook). I took the photos carefully with a 50mm lens and tripod and good lighting. But most of the pages are tilted a little off plane, that is, a little left or right or up or down. There's a sample attached.

When I first started this project, after a LOT of trying, I found a program in Photoshop that would drag four corners of a crop frame to square it all up. But that was four years ago, and I can't find it now. I just re-subscribed to Photoshop for this purpose. The Adobe tech suggestion to use Edit>Perspective Warp doesn't work. Another suggestion to use Filter>Lens Correction doesn't work properly.

There was a fairly straightforward process to let me grab one corner after another of how I want the photo eventually cropped in a manner that would square it all up and have consistent straight margins. It took about a minute per page but was as perfect as could be. Can anyone help guide me on this technique?

I have the pages in both CR2 (Canon RAW) and in JPG -- hoping to keep them as high quality as possible and then put them together in JPG or PDF electronic books for family members to share.

Thanks.

Have you tried the Perspective Crop Tool? It's hidden underneath the Crop Tool in the Tools panel.

Note: If you are transforming Smart Objects you can also individually move a corner by holding down the Control/Command key.

Hey Michael (and anyone else who really knows Perspective Crop):

OK it works great to straighten MOST of these copied scrapbook pages that are out of kilter. But sometimes -- about a third of the time -- when I Perspective Crop/Enter, the page loses its original appearance. It typically goes wider. So people in photos look fatter. Not cool. It's not keeping the original ratios.

To complicate this, when I Undo Perspective Crop and use Perspective Crop a second time on the same page, it almost always does it correctly with no wider distortions. I have no idea why. I've tried to be very attentive to anything I'm doing differently on the second crop and I see nothing. So, same photo of a scrapbook page, 2/3 of the time it Perspective Crops properly, 1/3 of time it ends up wider than I want and I have to redo it and the second time it's in the correct perspective.

Appreciate any advice on this. I'm trying to fix more than 1,000 precious scrapbook page photos.
