Smile for the camera, not because you’re having your picture taken, because it’s a bloody nice camera worth smiling for. 
 
Put out of your mind for a minute the tedium of hasty tourist snaps, restaurant selfies and your father’s unthinkingly composed family portraits. The Rolleiflex represents everything that is possible in a photograph, the rush of life as it flits past the lens; it also represents the élan of the auteur and the elegance of the connoisseur: thus, it elevates both photograph and photographer. 
 
Perhaps you have a friend with keen creative vision; perhaps you wish to commemorate a picturesque scene enjoyed together; perhaps they just like cool looking objects: write them a letter.
