I strongly recommend against trying to photograph your first (or even second or third!) total eclipse. You will be too distracted and frantic and might miss the best parts, the few minutes before and after totality and all of totality itself.
There are interesting things to observe during the partial phase that you probably can photograph (or attempt to photograph) without losing anything, such as the really cool crescent suns projected through pin-hole gaps between leaves under a tree. They get smaller and more crescent-shaped as the eclipse progresses, but don't get so fixated you miss the final minutes before totality! Also watch for the lighting effects, the distant and approaching shadow, animal and bird behavior, etc. And the people!
If you are lucky enough to see 3 or more total eclipses, you might consider attempting to photograph the corona, Bailey's beads, or the diamond ring effect, etc. but don't even try on your first couple of eclipses. Also, remember, a total eclipse is TOTALLY different (pun intended) from a partial or even annular eclipse, so those don't count.
