I'm a very basic user of InDesign. I essentially just use it to mock-up my printed portfolio - I'm a professional photographer. As I use double sided paper to print my portfolio, in Indesign I created a document that is made up of double page spreads. Sometimes there's one photograph on a page, sometime a photograph is a double page spread.
What I want to is simply output a PDF of the portfolio that maintains the format of a book, so the double page spreads are seen as a single "page", so as the user scrolls through the document, they see each spread in order.
The other thing I'm wondering is what options do I have to set how the document is viewed once I send it? I don't want to send potential clients a list of setting they need to plug into Reader etc just to see the PDF the way I intend.
Have a look at Publish Online, it may suit your requirements.
When you Export your Document you can try use Spreads option instead of Pages in General settings of PDF Export window
You have to set up your document in the size of a SINGLE page, not in the size of a spread.
You have to set up the document with facing pages.
Then you can export as PDF with single pages or with spreads.
