I was suggesting different principles be considered, not specifically suggesting one approach.
- one can control SATURATION of the background by projecting gels onto a) white, or b) grey, or c) black
- while one can control BRIGHTNESS via power/intensity of the light projected thru the gel
- and one can control HUE simply with gel color selection
The link (camera shot on the color paper) is dull and boring. So instead you can put the camera into a 'set' and illuminate your background (neutral colored paper) with a gel, and the level of illumination established by the power of the b/g light source, saturation is controlled with what the gel is projected onto.
Your latest post with photo of flash gear sitting on a acrylic plastic which reflects the background is that principle in action.
Additionally, one can use TRANSMITTED light rather than reflected light, as this is an example from a lighting workshop I once took. (This shot is actually a three part multiple exposure on one piece of film.)
In this particular case, the exercise was about using transmitted light, thru the background paper and (separately!) thru the glass of wine, not about reflective illumination of the set or wine bottle
