It's not the resolution.
Phone cameras use a very wide angle lens. They have to. The lens sits inside a device that's about eight millimeters thick, so physics demands a certain focal length. That focal length is wide, typically somewhere in the 24 to 28mm equivalent range, and wide angle lenses do something specific to faces when you're close to them. They stretch the nose forward, push the ears back, and make everything slightly rounder and larger than it actually is. The closer you are, the more pronounced it gets.
You've seen this. You've looked at a photo of yourself taken on someone's phone from arm's length and thought something looks off even though you can't quite name what it is. What's off is the distortion. The lens is lying about your face.
Actual portrait photographers use longer focal lengths for a reason. An 85mm lens or a 105mm compresses facial features in a way that's actually flattering. It makes proportions look natural. The nose looks like a nose. The face looks like a face.
You can get most of this benefit from your phone with one simple change. Back up. More than you think. Get two or three car lengths away from your subject and then zoom in, either digitally or just by cropping later. The distance between the lens and the face is what creates the distortion, not the lens itself. Put some space there and the distortion mostly disappears.
The other thing worth knowing is that most people hold their phone camera too close to people's faces when they're taking portraits. The phone is literally inside someone's personal space and everyone in the photo knows it. They tense up a little. Their smile gets a little more performed. Back up and zoom in and you solve the distortion problem and the tension problem at the same time.
For family photos specifically, the wide angle problem gets worse because you're trying to fit multiple people into the frame so you get even closer or use an even wider setting. The result is the people at the edges of the frame look stretched and the faces in the middle look fine and nobody is totally happy with how they look.
The fix is to not try to fit everyone in the frame by getting wider. Fit everyone in by getting farther away. Same number of people, more space, better lens perspective, everyone looks like themselves.
Your phone camera is genuinely capable of beautiful photos. Especially in good light. But the distance matters as much as anything else, and nobody tells you that when they hand you the phone at Thanksgiving dinner and say get a photo of everyone.
Back up. Zoom in. You'll see the difference immediately.
When you're ready for portraits that are actually designed to be flattering, I work with families all over the Fort Worth, Springtown, and Azle area. Let's make some photos you'll actually want to print.
