I am planning on shooting objects that will lay flat, eg. knives...do you think a light tent would be benificial, or will I have as much success with the two softboxes I already have? My main light source is a 150 ws strobe with modeling lamp and a 16X16 soft box. The other is a small generic zoom flash with a Lumiquest mini softbox. I appreciate any and all opinions and experiences...Thanks!
