A 360 photo on a location's card is only as good as the shot you feed it. A few habits at capture time make the difference between an immersive scene and a soft, awkward one.
Shoot equirectangular, at high resolution
Mapvera wants an equirectangular image: the wide 2:1 picture a 360 camera exports, or that your phone's panorama or photosphere mode stitches together. A normal wide photo is not the same thing and will look wrong when dragged.
Capture at the highest resolution the camera offers. Only a slice of the sphere is on screen at any moment, so detail gets spread thin. Aim for something around 4096px wide or more. Anything much smaller looks soft as soon as the visitor looks around.
Keep the camera level and still
Use a tripod or a steady surface and keep the camera upright. A tilted 360 makes the horizon rise and fall as the visitor spins, which feels off. Most 360 cameras stitch best when they are level, so a small levelling effort pays off across the whole sphere.
Stand back from the camera or step out of frame while it captures. Whoever holds the camera ends up huge and distorted in the final image.
Light it evenly
A 360 shot sees in every direction at once, so it captures both your bright windows and your dark corners in a single frame. Even, diffuse light gives the cleanest result. Overcast daylight or well balanced indoor lighting beats harsh sun and deep shadow. Avoid pointing one side straight into a bright light source if you can.
Tidy the whole scene
Because nothing is out of shot, clutter shows up behind the camera as clearly as in front of it. Clear away bags, cables, cleaning gear and anything you would normally keep just off camera before you press the shutter.
