shaun the logos by me would work on any dimension ...since the name is adjusted next to the initials in a way that it doesn't take up any extra space....and the place where the existing logo is currently anyof the logos by me would fit in easily
i chose initials as it would be needed for watermarking of photographs by you and hence developing the brand id on your initials itself would add a personalized touch to it too
I think it's very limiting what can be done with 'S' and 'T'... correct me if I'm wrong.
Also with me being a photographer it's easy to go with STP, which sounds like something you'd go to the clinic to get sorted. Hence why I'm steering away from highlighting that!
the reason i chose that style in 11 12 13 is since yours is wedding photography hence the curvy font and i inter winded them to show vows taken in wedding.
in #134 i made to S of your name flipped and intertwined to indicate 2 souls joining forever . the flower on top to indicate blooming of love. another hidden meaning being healing of souls as icon is along lines of Caduceus (symbol for medicine healing)
