I do family portraits/ couples portraits with a semi mobile rig about every 4 to 6 week. Either at the family's home,or a local park, or nature reserve.
I take along a flight case of stands, reflectors, reflector arms, bounce umbrellas, shoot through umbrellas, and a few modest sized soft boxes, a few black flags and gaffer tape and good assortment of A clamps and a tripod.
For light I use natural mostly, or use a Metz 60CT1, or an equally powerful old Braun flash. Most of the time this is used for fill rather than main lighting.
It is usually on 120/220 roll film with a Mamiya, and then I deliver a legible size image 6cm sq 8x10 contact sheet. The average session is 3-4 120 films - i.e about 30-48 images. Usually C-41.
I aim to deliver contact sheets along with an order form within 2-3days of the shoot.
I process my own film, and process my own prints. I usually do an 8x10 to show how a cropped enlarged image can look, and a second 8x10 on portra b&w paper to show the client what b&w can look like.
For this I charge a sitting fee of $60 presently at this stage if the shot is local to me, just to cover my costs.
I require a model release from all before the shoot begins, to allow me to market with their images and to attempt to give me a cause to chase/shame them if they want to just order one image, and clone them themselves. I have not had this problem to date.
I sell enlargement prints for 5x7 $7, 8x10 $10, and 11x14 for $25 for the first of an image, and about a 40% discount for reprints of the same image.
I offer mounting, custom vignetting, and other services on an ala carte basis to meet the client desires.
Sometimes I will get interest in the B&W and then do a session of just that priced at a premium, and will do 4x5 if they tell me that they are looking for 20x24, etc.
I'm not trying to get rich on this, just cover my costs, and keep my finger active in this scene.
