Will a soft reset / hard reset erase my photos?

Hi,

I have just reistalled Mountain Lion on my Mac-Air and Windows 7 on my PC. The only copy of a large % of my photo album is on my Phone only which is acting buggy.

I want to do a soft rest or hard rest to see if it fixes it but need to knwo if either will erase my photo album collection.

can you tell me:

-soft reset?

-hard reset?

Cheer.
