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

Answer: 
The original question doesn't have enough detail to really offer a solution here. But to clarify previous answers, the fastest way to transfer photos and videos between an iPad and an iPad 2 would be to sync to a single installation of iTunes/iPhoto/Aperture. 

A slower but simpler way would be to run Dropbox on the iPad, click on the UPLOAD tab at the bottom of the page, and upload all the photos and videos to the Dropbox. On the iPad 2, reverse the process and download all the photos back. 

If you're only talking about a few photos and you don't want to do anything outside of the Photos app, you could simply email the photos to yourself from the iPad and save them to your photo library (via the Mail app) on the iPad 2.

I suspect all three answers sound simplistic, but it's hard to know what you're trying to achieve and where you're getting stuck.
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.
