Same-sex weddings are pretty much the same. You simply have to go into it treating them as two people in love, which is really the same regardless of the sex of the couple involved as this of course applies to all weddings. But rather than thinking “bride and groom”, you think “couple in love” and it, at least for me, allows your brain to look at the couple as a couple and allows me to “get past” some of the typical shots I’d do if I had a male/female couple. Again, for me at least, as I see the couple (even though they are groom/groom or bride/bride), as two people in love, that helps me to adjust my day to what will work for them, leaving out (usually but again not always), poses like dips. You might actually be surprised as to how many “typical” shots still work, depending upon the couple. And as with any couple, you will always have to adapt to what will work for them. Some ladies will both have wedding dresses, an other times one will be in a suit and sometimes both. This can, but not always of course, lead to a dominant figure and you can alter some shots accordingly. Personally, I love the bride/bride weddings as the brides are always my favourite to work with. A bride with her dress and flowers always makes for a wonderful shot so two is just naturally twice as great. For the gents, it’s the same sans the dresses. And I actually find that in general, two gents are easier to work with and are more at ease than groom/bride. Oh, and then there is the bridal party. So yes, you’ll have to be prepared for a change there at times. Rather than some ladies and gents, you may find all ladies or all gents. Sounds intimidating but really, that just leaves out a few “typical” shots but can open up others. Are there favs you like to do with the ladies, or with the gents? Now you can do more because you don’t have to split your time and that sort of thing.
In all, it’s not really different and very much like your very first wedding. I saw your post on the other thread and yes, we were probably all petrified and sweated half our body weight on our first wedding day. It’s new and different (you know what I mean though, not odd but just different from the usual experience is all) but after the first, you’ll see it’s all great and you’ll probably be looking forward to more. I know I do. Because for me, I’ve always seen the couple as just two people in love and come whatever happens on the day, it all boils down to two people in love and everything around them is just icing on the cake.
