Image was taken in my wife's shop while she was teaching my grandson how to sew. Lighting was difficult due to overhead fluorescent's being a difficult white balance. Ended up adjusting white balance in post processing. No flash was used. In order to get short depth of field aperture was set at f/5.6, focal length at 35mm. Camera set in aperture priority mode. ISO pushed to 1600 to get shutter speed up to 1/80 sec,
