How do take good close shot photos of documents
Use Evernote. It has a dedicated Page Camera feature for your purpose. You can continuously snap documents with it.

If you are a premium user, keywords from your snapped documents will be indexed with OCR technologies (which will be useful in searching). And, it works great (I am a premium user &amp; I have used it). If you aren't, just buy premium subscription for 1 month... Indexing continue to exist after 1 month (but new documents won't be indexed).
