Question: How do I transfer photos and videos between iPad and iPad 2?

Answer: 
This depends, do you have iCloud? as you can sync through iCloud. 

You can also configure all the settings in iTunes. So you can import all the images into iTunes, once they are there you can connect the other iPad and sync them.

If you do not want to keep the iPad 1, you can just connect it to iTunes, sync it and then connect the iPad 2 and restore it from the back up of the 1st iPad.
No additional computer or "Cloud" necessary!

works brilliantly if you have a Camera Connection Kit (non-Apple one may even do)

You may need to reset the target iPad (press Home & Power button) to get it to highlight "import".

Remember that your charging lead goes from the source iPad & CCK into the target iPad. This idea is great if you're on holiday in a camp site for example.
