Out of the box git commit logs are a bit drab.

commit 015ac5ff9b39143c91d5dc136a2c8d578b733e27  
Author: Other Dev <email2@addr>

    added some stuff

I find the following a little more useful:

git log --color --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit  

git log

Which makes a useful git alias:

git config --global alias.lg "log --color --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit"
