Find the light before gathering the people
Choose a place where faces receive reasonably even light. If some people are in direct sun and others in deep shade, the exposure becomes harder to balance. Open shade can be useful, but check the direction of light and the colour reflected from nearby walls.
Look behind the group before inviting everyone into position. A small step sideways can remove a sign, a bright window or a distracting object appearing above someone’s head. Make those adjustments while the space is empty.
Keep every face on a clear line
Build the group so nobody is directly hidden behind another person. With more than one row, ask people at the back to stand in the gaps. Look carefully at both edges of the frame and leave room for a final crop.
Do not automatically use the widest aperture available. Depth of field needs to cover the group’s arrangement. Take a test photograph and inspect the nearer and farther faces before making the main sequence. A wider lens used very close to people can also make the people at the edges look stretched; stepping back may give a more comfortable perspective.
Make the instructions short and specific
One clear request works better than several people calling different directions. Ask everyone to look towards the camera, then give a simple cue for the moment you are about to photograph. Take a small sequence so a single blink does not decide the result.
If children are involved, organise the adults first. Keep the group ready for the short window when everyone is comfortable. Avoid balancing a child on unstable furniture or placing anyone where a fall or trip is possible merely to improve a composition.
Check movement as well as focus
Even a posed group moves. A shutter speed that suits a still room may not suit a laughing family. If the light is low, consider adding light or using a higher ISO rather than making the exposure so long that expressions blur.
Check the photograph at a meaningful magnification, but also return to the full frame. Technical sharpness is useful; a comfortable expression and an unobstructed face are just as important to the picture people will keep.
Keep the list manageable
For a large celebration, agree the essential combinations in advance and ask one person who knows the guests to help. Start with anyone who needs to sit down or leave early. Then let the event return to its natural rhythm: the organised group is only one part of its story.
