i personally have tried Jean Yip, Beauty Box & Chantel Goh...
Jean Yip - Sux totally... their style more to ah lians ... the make-up was thick & horrible .. almost equivalent to the "Ru-Hua" in "Shaolin Soccer"...
Beauty Box - More Natural Style... Make-up was so-so.. but the photographer (the boss) i find quite good leh cos he will chat & joke with u, making u feel comfortable & relax whiile he snap-shot your most beautiful & natural moments...
Chantel Goh - Make-up was good.. the make-up artist is very friendly but the photographer sux... she have no patience & always capture the most terrible expressions such as "blinking eyes...slouching shoulders.." she cud not even bother to correct u.. she juz make sure her job is done.. tats all... In the end most of my pics turned out tat i have my eyes closed.. or i looked like i was falling asleep anytime!!!
From my experiences.. so far i have not met with one i'm totally satisfied with...
