If you'd like you can just tell the photographer directly (if the job was already accepted).  You can get his contact info within the app by simply proceeding to MENU > BOOKINGS > UPCOMING > Here you can call, text, or email your photographer any specifics.  But if you need to edit the times and especially the duration, this can affect the payment and compensation.  So please make changes to the booking with the system if the duration is different.  


iOS app View (for web app please scroll below)

When in the iOS app you can find the EDIT function in the top right of the screen (MENU > BOOKINGS > UPCOMING > OPEN THE SPECIFIED BOOKING > SEE TOP RIGHT OF SCREEN FOR EDIT FUNCTION) 





Web App View 

BOOKINGS > EXPAND YOUR SPECIFIED BOOKING > CLICK DETAILS > Here you can contact or adjust the booking information.  Don't forget to click UPDATE when adjustments and edits are completed.
