I apoligize for the truly an ignorant question I have: Other than playing around for the last year with my Canon 40D, only now am I going to get serious and develope my portfolio. I have searched and read many forums about Shutter Speed, Aperture and ISO settings, definitions, ideals etc. BUT putting into practice I have not done much of and I losing sleep over screwing up my next photography session with out of focus photos... QUESTION: I have a family of three (mom, dad, and toddler) I am photography outdoors. Some shots taken will not be perfectly posed together, I'm sure. With portraits, I read to set my f stop to 1.8- 2.8 to get the beautiful focus on the subject and drown out background. But all examples of this show the subject just being one person. Does a f 2.8 work well for a small group setting such as three? I read forums suggesting the aperture to be set to f8- f11 for groups to ensure all are in focus. Obviously less of the effect I'm trying to create is applied. I'm just so worried someone will end up out of focus with the larger aperture. Would you reccomend an ideal aperture that is still considered "safe"?
