Idiotic Mistakes...

I love the title of this post Idiotic Mistakes to Avoid When You're Learning Digital Photography  which I found on the Digital Scrapbooking Day website.   Anna Wiliams mentions some good ones and...well...I have to admit I have done some of those too...

Here's one ....water or liquid of any kind and digital cameras don't mix well.  Don't store your water bottle and camera in the same bag.

How about you?  Any good things we can pass on so we can all be better photographers?  I'd love to here them....
