What is a collaborative photo shoot ?
It's just an exchange (the model offers me her time to pose and I offer my services as retouched photos), it's an unpaid shoot, sometimes called "TFP" (Time For Print).
During the photo-shoot, we sign a contract together, to give you the right to use my work and to give me the right to use your image on my photos. The best pictures of the session will be listed on my book (this website) and on my various elements of communication (Facebook page, Instagram, etc...).
During a collaborative shooting, I have no obligation of result nor number of photos. If the session is not optimal (bad light, annoying elements, photos not exploitable, etc...) then there may be very few photos delivered.
I may refuse requests for collaboration, especially for simple portrait projects because I get a lot of requests of this type, and the project must also be interesting for me.
