from my early days of wedding photography, I came to learn that there is a lot of dirty tricks used by wedding studios (not all, some are ok), so be very careful and if you want to work with them go in with 2 eyes open. Some of the dirty tricks i have come across in the past include
1. They will ask for your portfolio album on the premise that they will sell you, then they will claim your works belong to their "in-house" photographer, and so when clients want your pics, instead of calling you, they will get some photog from JB to come in and do the job at 1/5 of what they would pay you.
2. They will withhold payment from you and always have a few bills outstanding, then they will say, after you shoot this one, we will pay you the past bills, but they will always keep one or two bills outstanding so you have no choice but to keep shooting for them. so you will be forever stuck to being paid very low
3. they just pay very very low to begin with (i've heard of rates as low as $250 for a full 14 hour day) with promises of more work in the future. in most cases, if you do the proper math, you will end up losing money if you are based in singapore. why do you think so many of the shooter they use are from malaysia/johor?
There's quite a lot more dirt in the industry, but these would likely affect you most.
If you are doing wedding photography to make money, i think there's really no shortcut to finding a viable and profitable model. My experience with photographers who have come for advice in the past and then ended up going and shooting for a bridal studio, after about one year, as they say in singapore "no sight no sound."
In fact, for many years before WPN came about, wedding day,both actual and pre wedding was at the mercy of the bridal studios because many photographers in the industry depended solely on bridal studios to bring in the business. That was the heirachy back then. I am glad to say i the last few years, wedding photographers in Singapore have made huge advancements and are less at the mercy of the bridal studios. they can now set their own prices and can survive off walk in customers. As a result fo this the qulity of worked being produced as sky rocketed too.
In short, starting through bridal studios is not a path i would walk if you plan on doing it for the long term. bad for you, bad for the industry.
