I did it. I went to a Do It Yourself this last saturday and found my new background.
I was hesitating about the color but the store helped me as it has only two of them : green and white. For me, the green one was too "dangerous" so I took the white one.
I know it is a "common" background and many other DXers have it but it was my only choice.
So here are some new pics of my old new additions...
Thanks Luciano !!! I agree with you on the fact that it is not the best color for white cars. Not good for the contrast. But for example, with the BMW, which is not totally white, it permits to see the "non-white" details very well.
Thanks Felix !!
My lighting setting is quite simple... Sun, window and that's all.
The only thing I did is to be perpendicular to the window so that there is no reflections on the BG or the model and you can not see the window on the BG.
I will try this with lamp settings at night when I get my new models (on their way...) with the reverse side of the BG.
About the reflection, it is only due to the background (I think)
