How to take pictures for selling

Thank you

Most important is good lighting.  Do not use a desk lamp, casts too many shadows.  Use a light source that is somewhat directional but diffused-window light with a piece of white cardboard opposite the light source as a reflector.  Window light works well if its balanced w/ a reflector.

tripod if you have it

make sure if you are using a camera  vs a cellphone is to use a decent f-stop-  F8 is good   set your iso at 800- 400 is better but 800 helps in low light

keep the background uncluttered- use a empty wall or a sheet hung behind the gear but not too close to the gear.

I like to use manual settings with natural lighting (ie the sun through a window whenever possible) and take several bracketing exposure time photos around what initially looks best then choose the one that shows the unit best. I always use a tripod to get the sharpest image with longer exposures, usually over-exposed for a brighter more pleasing shot (loudness wars!) but in dimmer light so lights and indicators on device can be seen clearly along with the rest.

I let my iPhone do all the work.

My pet peeve is people not photographing the back of gear, both components and speakers!
