I realized this after I sent the reply but thought you would be polite enough just to accept a compliment. Guess not.
My fee for an hour family session is $50. for one hour. If it runs over that, $25. for an additional half- hour. A family shoot shouldn't take that long. I charge for travel if it's over 20 miles, usually $25.
Any prints, or additional services are extra. You should look on line for what the professional labs charge for their services and, of course, build in a profit for yourself.
In the final analysis, it is what you feel is comfortable or fair for your services. Best of luck!
I had the same problem with my computer. The driver was out of date. Check your Device Manager under "Devices & Printers" and if it has a little yellow !, click it and it should be able to solve your problem. Good luck!
Personally, I think this is a great look but when I have used it on clients, 99% of them go "OOOO_HHH-No!" But they said that to Van Gogh and Picasso.
