Window light has to be my favourite light source, although sometimes tricky to work with unless you understand how to control it.
This image was quick and simple in execution. Two locally grown garlic bulbs hanging from garden string tied to a short articulated arm. Window light from camera left, 18 inches from the white net curtain. The sky was light grey cloud so diffusion the sun like light Grid Cloth. Backdrop a reclaimed grey Welsh slate roof tile supported by two A clamps. Separation from the shadow area of the garlic to camera right by means of a homemade V-flat reflector bright silver side, positioned to reflect light back from the window. Camera Fujifilm X30, handheld with my elbows resting on the bench top.
If you're serious about your photographic lighting then maybe The LIGHT Side Facebook group https://www.facebook.com/groups/thelightsidegroup/ will interest you. It's about all things to do with light and lighting. TLS is a closed group so someone will need to add you or you'll need to send a request to be added. It's a friendly group, with a degree of humour and some great photographers willing to share and contribute.
