So it's worth spending some time thinking about the style of wedding photography that suits you. Although there appear to be lots of different styles they fall into three main categories:
Revolving largely around posed group shots, with the photographer as an organising presence, structuring both individuals and groups. Still very popular, this is probably what many people think of when you mention "wedding photography". This can produce organised if static group shots, but inevitably the flow of the day is interrupted and many of my clients mention weddings they have attended where a photo session has lasted over an hour - something they are keen to avoid.
Reportage, informal - the emphasis is here on capturing moments and events as they happen. The photographer is recording rather than organising, so the photographer should be a less obtrusive presence. However, there are many different interpretations of this and it's worth checking the pictures of any informal or reportage photographer to see if the style is right for you - one of my clients had seen "reportage" photography that in her phrase was "all backs of heads" but loved what I call reportage photography.
This is a variation on i) in many ways, the intention is to create pictures that look more relaxed, more fun and more varied. It still involves spending time away from your guests, and creating moments or events that did not happen naturally or of their own accord. Perhaps a classic familiar example of this is the shot of the bride, groom and bridesmaids holding hands, running across a lawn - a shot that had to be organised and didn't just happen. This style tends to be focussed largely on creating and setting up stunning images of the bride and groom.
Henry adopts his style to suit his clients - his natural style is the ii) informal or reportage style blended with i) and iii) to suit each client. Whilst some clients want a totally fly-on-the-wall approach, many still want some family groups as well. Style iii) for some images is very important to some clients.
It's worth spending time thinking about what is right for you. By combining styles to suit you Henry is able to produce images that reflect the two of you without taking over the day - he is particularly pleased with the comments in the testimonials that show you can have great wedding photography without spending a large chunk of your day with the photographer.
