Good ol' Spencer... I've known about him for quite a long time, and have always been intrigued at what he'd do next.
Recently though, an opinion has been raised that maybe his work is going downhill. It's not, just wait and see what he does next. The recent work certainly may not be his best, but the location wasn't the best either. If you've kept up with his work, you'd know that he normally chooses better locations than a simple hotel or a pool. I believe that the champagne shoot was merely him trying something new. Judging from the pictures, it appears that the people were having fun with it.
As for choosing to do an all-female shoot, it's certainly not his first. Back in June he did installations with 250 women and another with 250 men. Previously, he's kept a select group of women around after a large-scale shoot to do some other shoots. He's not being sexist -- it's very common and accepted for photographers and artists to prefer females. (I know this from previous studies.) Even most women photographers prefer to shoot women, and both males and females prefer to look at females. Why? Females are curvy, sleek, and have subtle sexual organs. Males are ridged, fuzzy, and have very overt sexual organs. This same preference can be seen with cars -- do you fancy the sleek curvy ones or the ones that look like a box? I'm just happy that Spencer is still doing mass shoots with anyone and everyone, instead of picking all women all the time.
America (and the world, really) needs a cultural shift into being more comfortable with nudity, to the point where clothing is worn when needed instead of from habit. Some say that being nude with others at some point should be mandatory. The only way to get people to realize the comforts of simple nudity is to strip them down in a positive environment. You and I don't even come close to achieving this task on the scale that is needed. Want to know who does?
In the last 4 years, Specer Tunick has stripped down 38,147 people in a nude-positive environment. A vast majority of those consider the experience of being nude with others quite liberating. (Us nudists already know all that, so I won't detail all the participant's descriptions.) My questions is: How many of those do you think try a nudist resort or beach later on? Or at least have a positive attitude towards nudity? Even 5% is a pretty significant number -- almost 2,000!
Spencer is certainly leading the way in liberating the masses -- I for one am cheering him on! (And even his copycats!)
