When taking pic of dark fabric - do not shine the light on the item
I take my pics in the bathroom. I hang the item on the shower doors covered with a white or black sheet,
I clamp a light on the towel bar on the one wall and clamp another light on the wall directly across from it.
I shine the lights at each other
and I snap the pics through the light at the item.
My only problem is greens like to turn brown!
It's my camera I'm sure because even when I attempt to try it outside
the fabric turns brown in the pics.
LOL, but the grass is always green, lol.
So try snapping pics through the light instead of shining the light on the item.
