Can you as a model get the photographer to sign a release of your photos?

Models do not have release forms that they have people sign. It is the photographer that offers the model a model release because by law the creation/rights of the images are automatically given to the photographer. You must waive your rights to the images unless you want to pay the photographer a buyout fee, which they usually do not offer or is very expensive.

Models in general are allowed to use the images for promotional purposes when signing a model release so as long as you are able to do that, then you do not need to worry about owning the rights to the images.
