Overall a beautiful backdrop. More yellow than I was expecting though. The yellowish center on mine is very large and bright, with much less brown/green than the one pictured. I used it for a dance troupe portrait and the yellow wasn’t flattering with everyone’s skin tone. Too bland. However, I changed the color in post and I LOVE the result. The yellow center became a natural bright spot under whatever color I painted with, and is a lovely effect. I have included pictures. The first one is mostly unaltered in color, just darkened a little. I am keeping the backdrop, knowing that I’ll have to be careful with subject/lighting or paint it in post-processing.
What this tells us is that the further away the light source is from the subject and backdrop, the more likely we are to get an equal exposure from one to the other. The quality of the light source can also change with distance. You will notice that as the light gets further away it becomes a harder light with less transitional values. Also, if the subject appears to be further away from the backdrop in the last image, it's due to me needing to use a shorter focal length (zoom out) to avoid getting the softbox in the shot. The shorter focal length exaggerates perspective.
Made of moderately thick, heavy material, canvas used to be the most popular among photography backdrops. However, due to its bulk and cost, it has been overshadowed by muslin backdrops in terms of popularity. Nevertheless, a good canvas backdrop will last a long time and provide a classy look to your shots. While you can bring canvas photo backdrops with you, they’re best suited for studio work since they easily wrinkle when stored in a duffel bag.
Position these lights to point at the backdrop and use manual settings to achieve the “blown out highlights” effect. Make sure the light reading is at least 3 stops higher than the light on your subject. Light bounced off the blown-out background will also create a back-lighting effect on your subject, the degree of back-lighting depends on the angle at which background light are pointed at the background.
