For OSX users, I've developed a simple, fast and free instructional that is a precursor to processing images with Scan Tailor (or any image editor/ebook builder you prefer). This instructional is for users with 2 camera scanning systems that are looking for an efficient way to order their images accurately prior to processing for ebook construction.
This method utilizes free Apple software found on factory shipped OSX versions. This workflow has been running successfully with the following versions:
iPhoto 8.1.2 OSX Snow Leopard
If prior versions of iPhoto perform the outlined steps below, please reply to the post.
STEP 1: Import Raw Images from Cameras
Each camera will offload the images onto iPhoto where they are called 'events'. For learning purposes, label each event to correspond to the left and right cameras (this will eventually help you understand how to interleave the events into proper page ordering in a later step.)
STEP 2: Rotate all images in each event.
Select all images in the left camera event. command-R will rotate clockwise 90 degrees each time you enter this key command. (Although Scan Tailor has a rotating feature, batch rotating the images in each event prior to their merging is faster and easier if you perform it on this step.) Repeat the above rotation steps in the right camera event.
STEP 3: Batch Change 'Dates'
This step is crucial to get correct. The first couple trys may take time to understand correct order of operations, but once you do it successfully, it will make perfect sense.
Image Order Theory: The right camera always takes the first image, i.e., page 0 (which is a black blank void if you capture book covers on the opposing left camera). The left camera takes the 2nd sequential image, or the book cover, a.k.a Page 1. Because we always will want the cover to be the first page, we will delete the 0 page. Make sure you delete the 0 page before batch processing the dates as described in this step:
(Depending on what image you shoot as page 1, you should date that corresponding event accordingly.)
Now that we have identified Page 1, we can begin ordering our images for book compiling. Select every image within the left camera event and control-click> a menu will appear> select "Batch Change..."> select "Date" in the selection box> batch change every image starting at 12:00:00am, with 1 minute intervals between each photo.> "Modify Original Files" should NOT be checked, as this will save you time.
Next, we will go into the right camera event and select every photo and batch change dates just like in the right camera event. Except we will change the starting to date to 12:00:30am, with 1 minute intervals between each photo. (What we did here was stagger or offset the dates of the photos in the right camera event to interleave in sequential page order with the left camera event."Modify Original Files" should NOT be checked, as this will save you time.
STEP 4: Combine Left & Right Camera Events
Exit out of the right camera event and into the events overview in iPhoto. Drag either event into the other (doesn't matter which one combines with what).
Go into the merged event by double tapping or clicking. Make sure that view>sort photos>by date is selected in the iPhoto menu. This is a good time to zoom-in on photos (by pressing the space-bar, NOT the return key) to check if the pages interleaved correctly. If they did, great. If they didn't, you have the option to undo this merge. (FYI: the minute you start editing photos, or use the return-key to zoom in on photos after you merged 2 events, you will lose the option to undo this procedure. My advice is to confirm that the pages interleave correctly, but if they don't, locate the page number where it falters, mark it with a star rating, and then undo the merge. My experience shows this is easier, as fixing a merged mess of photos can take a long time. Another useful tip is to set the firmware on one of your cameras to count images in continuous mode, and another in cyclical starting at 1. --This way if you lose the option to un-merge events, you can sort the view according to file name).
STEP 5: Batch Change Image Titles to Sequential Numbers
In the merged event, select all the images, contrl-click "Batch Change..", and from the the selection box choose "Title-to-Text". I leave it blank for speed of my workflows, but you can append any name in front of the sequential page ordering. Make sure "Append number to each photo" is checked. This will order every page sequentially.
STEP 6: Checking for Missing Pages
This is really useful for checking to see if you missed/skipped/duplicated any pages when you scanned your book. (if you purposefully skipped pages, such as a magazine with advertisements, this step won't be of much use).
All you need to do here is locate the true Page 1 within the physical book. Once you find wherever page 1 is located, select every image from there to the end of the book. Follow the steps in STEP 5 to batch change the title of these selected images. Once you have renumbered the images in relation to their physical page numbers, zoom in on an image near the end of the book. If the page number correctly corresponds to the title of the image, then you can conclude the page ordering is correct, and you did not skip any pages during the scan.
If the numbers do not matchup, you can simply skim through the images until you find the mis-matched/missing/duplicate pages. There are a number of tricks to insert missing pages in iPhoto. If you run into problems, I can elaborate in detail how to make edits in your events. But it should be a rare occurrence if you scan thoroughly and follow this instructional.
Once page order is finally corrected, batch change the entire set of images for the book again as mentioned in STEP 5 (this assures proper ordering upon loading the images into Scan Tailor)
STEP 7: Cut Out the Fat
You'll want to remove blanks or worthless images at this step. They serve no purpose to process, export, so once correct page order is achieved into a single event, you can toss these images without hindering page order. You can cut the image from the event the image by simply pressing delete.
(NEVER CUT THE FAT WHEN YOU HAVE 2 SEPARATE EVENTS; YOU WILL DISRUPT SEQUENTIAL PAGE ORDERING!!)
STEP 8: Export images for Post Processing
Once you have a clean-ordered set of images ready for post-processing, it is time to export these versions & their modified titles to a new file folder for Scan Tailor. In event view in iPhoto, select the event you want to export. In the iPhoto main menu, select [File>Export...] Make sure that "Current" and "Use Title" are selected in the appropriate dialog boxes.
If you have any suggestions which could make this workflow faster, easier, etc., please share you ideas.
