Thay say that everything depends on the softbox <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite1" alt=":)" title="Smile    :)" loading="lazy" data-shortname=":)" />?Small diffuser si less than 0,65 m2.Medium 0,65-1,3 m2.Large: more than 1,3 m3.For small diffuser (5 stop strobe) appropriate 200 Ws.For medium 300-400 Ws.For Large 500-1000 Ws.Fot the object photograph i need aperture f/8-f/16 (perhaps even f/22). In this case, a small space should not be a problem? OK, shadows. Solve apparently the glass base?Well sometimes i would like to do the portrait.Yes now I need more space.I need additional 2 m (distance to the background because of shadows).For portraits i need medium softbox (to 1,3 m2), therfore 300-400 Ws.Subject to diffuser distance must be 1-2 times the diagonal of the diffuser. The kit Bowesn 400 rx contains umbrellas 90 cm. Therefore, this kit the most useful at a distance of 90-180 cm.At 1.8 m (1/32) we get f/5.9 =f5.6 (-1 or 2 stop) If I am right remains the only problem ceiling height.This means bye bye umbrella and welcome diffuser?Can anyone tell me the relations between size of the space and Ws. For product photogray would probably suffice 3x3 m?For half torso portrait 4x5 m?Sorry if I'm too long <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /></blockquote>
