Splitting a landscape spread into 2 portrait pages?

"Make two copies of the PDF--then crop one for the left page and one for the right page. "

One can do this also by exporting one single PDF document with two PDF pages for every InDesign page.

You simply need a sequence of page numbers in the input field of the PDF Export dialog where every number is written two times like:

1,1,2,2,3,3,4,4

and so on. InDesign will send every page two times in sequence to the exported PDF.

In Acrobat's Print Production section under Set Page Boxes you can apply the cropping for every second page with "Odd Pages Only" or "Even Pages Only".

Here a sample document with a landscape page size of 297 x 210 mm that is meant for a brochure with 148.5 x 210 mm page size in portrait mode with two pages per spread where currently there is only one:

Note the numbering scheme in the PDF Export dialog.

Now in Acrobat Pro you have the chance to crop pages for every odd or every even page throughout the PDF document:

Repeat that for every even page, this time crop from the left:

No. You can't do that but you can set up a new document using Derek's instructions and then place the PDF you exported from the original document.

Then export a new PDF.

When setting up your InDesign document for your book choose the TPS (trimmed page size) 8" x 10", facing pages and add bleed, normally 1/8 / 3mm. Although you may design as facing pages, the printer will normally want single pages so they can impose the document to suit their printing requirements. This can be undertaken when you export the work as a suitable PDF for your printer.

Yes, add 2 single pages just after the double page.

copy photo and paste the photo on one page. Close the window to the right, the on the 2 second page added paste photo and close the window to the left to fit the page.

Be sure the phot has the same positioning on each single page. 
The delete the spread page.

It would be easier to do it in Acrobat Pro. Make two copies of the PDF--then crop one for the left page and one for the right page.
