I think photoshoot may be one of the most durable wedding expense. It lasts for years, Alot of people get to see it, who may not have been present at the actual event (like your children), you do end up looking at it a lot of times (more than the number of times you wear your shadi jora for example) and also it doesnt cost that much . keeping all this into account , i think one should get it done.
P.S
I’ve heard its also a lot of fun getting your pictures taken like that. i havent had it done just yet so wouldnt know.
