Rozzie, kiko94 has created a detailed and informative tutorial on making pools, including the heart-shaped pool. You'll find his instructions here:
http://www.carls-sims-3-guide.com/forum/index.php/topic,6378.0.htmlTo make a Sim a photographer, as soon as your Sim has a skill point in photography your Sim will be able to register at City Hall as a self-employed photographer. If you need information on the photography skill, I suggest you check Carl's Guide which has detailed information. To be a self-employed photographer, you need
World Adventures (which introduced the photography skill) and
Ambitions (which gave us the self-employed option).
Also, I edited your post to remove excess smilies and correct punctuation and capitalization.
