We want to prepare a book for electronic publishing on iPad by using InDesign. Hence in the InDesign's Document Setup we entered as intent 'Digital Publishing' and as page size 2048px X 1536px.
We took a photo output from a Canon 5D Mk III and processed in Photoshop CC and imported it (by Place) in InDesign eiter via TIFF or PSD.
The image(s) is/are 5380px X 3704px (a very small crop was done). The dimensions are according with Photoshop CC's info and XnView MP Properties pane - I mention just two programs which say the same. Also knowing Canon's 5D3 sensor's resolution, the numbers are quite logical.
However, in InDesign CS6, the photo appears as a 1614px x 1111,2px image and in order to fit it to the width of the 2048px page, we must enlarge it at 126,88%
Why is that? Why a 5380px X 3704px photo is placed in InDesign as an 1614px x 1111,2px image? (approx. three times smaller)
Perhaps I should note that the recorded DPI in Photoshop's file is 240x240 but I assume that since I set up the InDesign document to be for 'Digital Publishing' and the units are pixels, my image should remain at the same pixel dimensions.
