You already have the camera
A modern phone is more than good enough to make your business look right online. You do not need equipment; you need a little light, a clean frame and to know which few shots are worth having. Here is the whole method.
Light is everything
Shoot near a window in daylight, with the light coming from the side or front of what you are photographing—not behind it. Turn the flash off; it flattens everything and kills the mood. If a room is dark, wait for better light rather than fighting it. Good light does more than any filter.
Clean the frame
Before you shoot, look at the edges. Move the clutter, the cables, the stray cup. The single biggest difference between an amateur photo and a good one is usually just what got left in the shot.
Get closer and keep it steady
Fill the frame with the subject instead of zooming. Tap the screen to focus on what matters, hold the phone with both hands or brace against something, and take three or four of each so you can pick the sharp one later.
The shots worth having
For most businesses you want four kinds: the place (a wide, welcoming shot), the product or result, the people at work, and a close detail that shows craft. Those four cover your Google profile, your social feed and a simple website.
Edit lightly—straighten, crop, a small brightness lift—and stop there. Over-edited photos read as fake. If you would rather have this done properly at some point, it is the first thing our content production covers; until then, this is enough to look like yourself online.
