Como resolver conflitos entre modelos e clientes?

Conflict management plans should be put in place by both client and contractor before pre-production starts. If a conflict arises the best coarse of action is to address the issues early and collectively find mutual benefits for each of the parties involved. Prioritize the issue over getting the project done, not addressing the issue upfront could lead to the problem developing into a much larger problem while the project is underway.

The best way is to send a mood board ahead, if there will be changes during shoots, ensure that you are on the same page and they agree to it. At the end of the shoot, make sure you both sign a model release form that gives you the authority over the images.

Prevention is the name of the game here. I'd say most issues can be solved with a clear contract outlining the usage of the images (territories, surfaces, duration etc.), as well as a shot list that will prepare the model/ talent for the shoot! Models are often the last to know what's going on in a production and it goes a long way to treat them as any other crew member on the shoot (because they are!).

To communicate clearly also be a good listener. Have a written agreement, and a story board or at least a plan before shooting begins. Have a preshoot meeting to discuss and confirm what is expected outcome from the photo session. Treat your clients and models as you would like to be treated. Most conflicts can be resolved with compromise. Think of back up plans to introduce to the client and/or model that might resolve issues. Have a sense of humor!

Well, models must feel comfortable. Ensure they have a separate changing area that has a door, if you are photographing a subject matter that involves vulnerability and maybe partial nudity, there must be another person present and you must never touch a model without permission.

Diffuse conflicts with humour and let the environment be fun. Have music or an old movie playing in the background. Address the issues arising upfront, do not force situations, if a model is not comfortable working with you or is not of an acceptable temperament, you may suggest you talk about the issue or outright postponement or cancellation. Do not force models to do your bidding. They'll remember it as assault.

If you cannot resolve conflicts yourselves, try the agencies that sent them to you. If that fails, I suggest you measure your losses and move on. If not you may use the services of your lawyer.

Respect the model, buy lots of food and refreshments for your shoots. Have good music playing and make the creation process a collaborative one.
