Hi Wendy,
Maybe you can think about places u n ur HTB like to go. Can go there for photoshoot as well. See if there are any places both of you like e.g. beach, old shophouses, lallang field etc. Actually you can talk to your photographer, he will be the best person to advise which type of venue is suitable for u 2. E.g. my HTB and I thought of all the places we want to go, when we told the photographer, he told us not so suitable for us due to all the reasons he gave us. So he suggested elsewhere and I simply love how the photos turned out. A pity I have not collected my album, else can share with all the brides here.
For me, I would rather postpone the session to another day if it rains. After looking at my photos, the bulk of the photos (I think about 70-80%) I picked were from outdoor, not the studio ones. Very limited photos can be taken in the studio, unless your studio has very nice backgrounds etc (I know some studios do have). However, if you studio only changes colour of the background each time, then I think your album would be rather plain without the outdoor photos.
