Colcough used his status as an experienced fashion photographer to lure models to his studio and sexually abuse them, for which he has now been imprisoned for seven years. His behaviour was designed to belittle, humiliate and disorientate his victims.On her blog, Ivory told how - on a shoot with Colcough - he asked her in-depth questions about her sex life and repeated the mantra to her ‘you are vulnerable, you are vulnerable.’ It was only after learning that other models had suffered worse at his hands, that she decided to speak out and encourage others to come forward.The case stands out because it diverges from the common narrative of ‘vulnerable teenager in a foreign land, thrust upon a lecherous photographer by a pushy, uncaring agency.’ Instead, Colcough's victims were often in their mid twenties - experienced in their field.So just what makes a model stay and endure such an ordeal at the hands of a sexually aggressive photographer? What prevents us from leaving at the first whiff of danger?To understand better, I think it’s important to explore the psychology behind the relationship between photographer and model.To be a successful model, you need to be able to harness your vulnerability. You need to stand before the snapper and place your insecurities and trust in his hands (for it is usually a he).A good photographer knows this and will guide you through your shoot by boosting your confidence, reading your levels of discomfort and buoying your energy. This trusting relationship is why I’ve been able to put my fear of heights to one side in order to stand on the edge of a mountain in skyscraper heels and look down into the photographer’s lens as he stands at the bottom of the sheer drop below. It’s how I've managed to look happy and carefree in my bikini, even though I was turning blue under the heavy fall of a glacial waterfall in the Alps. Trust is a vital component of the working relationship between photographer and model. To say no to their requests is to look unprofessional. No one wants to be saddled with the tag ‘diva’ or ‘moaner’, including me.I’m 29 and have been modelling for thirteen years. Yet, it’s absolutely true that an experienced model like me can still fall victim to abuse and intimidation on shoots. Our careers are maintained by having a good reputation and this involves fulfilling a brief and not being seen as difficult by clients. That makes it hard to speak up when we feel uncomfortable.Today, I feel confident enough to stand my ground and contact my agency for advice. But it has taken many years for me to feel this way. There are certainly shoots that I wish I could travel back in time to and say no to a client or photographer's demands, and report their behaviour. Sadly, I was too afraid of losing work.A few years ago, I almost got myself into a situation with a photographer who has now been jailed for rape. He was then making a name for himself in the world of high fashion and celebrity. After meeting me on a casting, and unknown to my bookers, he began a campaign to persuade me - via Facebook - to come and stay in a Liverpool hotel and do a shoot, which he promised to show to a well-known brand.I had recently been dropped by my agency of five years and my confidence was shattered. That such an in-demand photographer wanted take shots of me would, I felt, boost my self-esteem and career. I was a street-wise model, with years of work behind me. Yet the allure of a popular photographer and the promise of work almost made me put aside everything I knew about taking risks and my own safety.Thank goodness I decided not to. In a hotel room, far away from the regulation of my agency, who knows what kind of photographs he might have persuaded me to shoot. And if anything untoward had happened, I feel pretty sure that I would never have told anyone for fear of being told I’d been ‘asking for it’, having willingly gone to a hotel room with a man whose website showed sometimes sexual images.I’ve since met girls who were persuaded to go and ended up sleeping with him. They couldn't explain why.But I can understand why models continue to travel to such shoots and work with photographers such as Terry Richardson - who manages to maintain an incredibly successful photography career despite a constant swirl of accusations about inappropriate sexual behavior on shoots (which Richardson has strongly denied). To turn down a shoot with Richardson would be dicing with one’s career, as he works for such enormous brands.What is clear, is that the abuse of models is far more nuanced and complex than the entrenched narrative of a young, naive girl being preyed upon. Any model - regardless of her age and experience - must place her trust and her professional reputation in the hands of a single person, every time they go on a shoot.It's all the more reason we must speak up. We have remained silent - out of fear of not working again, or simply not being believed - for too long.(telegraph.co.uk)Bakudaily.Az
