Do I need to fill out a model release form for photos I have take of myself as a photographer?
YOU as the photographer never need a model release. It is the end user who is going to publish the image, and potentially violate the model's rights, who needs the release. You as the photographer cannot violate your own rights as the model.
If you were to license the image to a publisher they could/would need a release signed by you as the model.
Edit: if you get a model release it either needs to be a release (waiver of rights) to you if you are going to publish the image, or it needs to be transferable to the final user who is going to publish the image.
No, if you are the one that licences your photos, you will be always tacitly licensing to the third party, unless otherwise stated in the licensing agreement, your image for the same uses you have licensed your photos.
Legally you cannot transfer your rights, as the model, in your photo to yourself. It is a legal oxymoron. In the rare and lucky case that you had previously signed the Full Rights of your Image to another entity, eg. “Nike”, you will be the one in breach of contract with “Nike” and not the publisher that has acted on good faith.
But publishers may end asking for one just because it’s what they usually do… and it would be easier to provide it than make them to legally think.
