Hello fellow photographers! Im wondering if anyone more experienced in lighting could give me some input on this topic. I have been shooting for 15+ plus years, I have always preferred and enjoyed natural light, I have shot with strobes and speedlights when i was doing more media work and the people i was photographing were still. I have started focusing on children, newborns and family and for the most part i use the natural light in my home studio. I recently had a cakesmash session and right before the the clients arrived the lighting completely changed and the sun was just way too strong and shining in a weird position where i had my set up, so i rolled my roller blind down and pulled out my speedlight and put it in an umbrella, now my issue and inquiry here is, when i shoot with the speedlight my aperture needs to be at 1/160 other wise i get the black bottom bar, the subject is a 1 year old who doesn’t stop moving, although i got enough good shots because i over shot, there were so many blurry images where his face wasn’t sharp at all. My settings were 1/160, 2.2 and around 200 - 300 iso, my speedlight was on ETTL and on high speed. My question is, how do you get the image sharp shooting 1/160? Especially when the subject is always moving around. Does anyone have any lighting recommendations for photographing children?
