good grief? favourite? we can have a favourite?
Man, as long as I am shooting... who cares!?!?
I have to confess that I think the most dificult is children (have no illusion friends... newborn babies are just not lying still!!!)
The most challenging is weddings... You can't interfere or move people arround too much, you start with an editorial style, switch to glamour for dressing up, switch to fashion for pre ceremony, swith to editorial for ceremony (with some fine art thrown in for good measure) then back to family photographer for the families and groups, and so on and so forth. The whole while you need to make the crapiest locations look like fairytale castles!
You have to have the patience and steady hand of a wild life photographer, for low light shooting, and catching just the right moment
You have to have the speed, agility and responses of a sports photographer to catch the frigging flower girls and other general action.
You have too carry all of your equipment like a Yak
and you have to smile and be creative for the better part of 12-16 hours on a day
(it also helps if you can do Crisis Management, and therefor, I can do a mean hairdo, have done a make-up course, can sew wedding gear (or my better solution = staplegun), know which calming meds doesn't go well with Champagne, can drive, carry extra sweets for difficult ring bearers (aged 3) and extra sunblock for hung over best men. I can also tie a straight, windsor or bowtie, and used to carry extra packs of batteries/film for when the mother of the bride run out, and an extra medium size black belt (worked into the cost of the wedding beforehand) for the groom/best man/father of the bride...
... Man I love stock!
