OK< I am going to try and be serious here......
Well, maybe not. But, here is a technique you can practice which may help to shoot photos of folks you know. First, sit down with a photo of a stranger and practice using the tools in your post processing to reduce the wrinkles, skin blemishes, etc. Once this is mastered, then ask one of your relatives who is a little reluctant, but not adamantly refusing, to help you with a project. Important here to ask them to HELP you with this photos project. Sit down, talk with them in good enough light so you can point and shoot. And this is just the two of you. Then, hold the camera, talk about how you are trying to do some new photos and tell them they can help you. Chat for a few minutes, ask if they take photos, ask what their interests are, or how their day is going, and very gently let hem know you are going to do some shots. Keep talking to them and ask them to move, click away a few shots and no matter what you think the shots look like say something like "oh great, yes, that is it, you are doing great". Just talk to them positively. Often it helps to use 4-6FPS. But, keep talking, asking them to look up, look down, sometimes to wiggle the head back and forth, lick the lips, and keep encouraging.
After five or ten minutes you should have shot maybe 50-100 shots. Let them know how appreciative you are. If they ask to se them, tell them you have to edit first as that is what photographers do now days.
Then go to your post processing and after editing from 100 down to 3 - 5, and this means deleting from the disc all 95 rejects, then begin to make the subject look about 10years younger in post processing.
What you will have accomplished is to reduce the fear of your subject, increase you down confidence you can do this, and might even get a photo of the subject which is one they like.
Now, if you had trouble following the directions, then you know what the problem is. You simply cannot follow directions....ha, ha,ha....I have done this with a young man who could hardly hold a camera and before the shoot was finished, he was talking like a pro. Of course in that situation we had a New York model with about 15 years experience. That did make it a bit easier.
And, my teenage years were in the fifties....so no old f... stuff, please.
