This roll of radiator reflector foil was inexpensive to buy. I can’t remember exactly but I think it was less than ten dollars (USD). Similar to above, this option works in the same way.
I recreated a similar test of my daughter in my Mum’s back garden using the small white plastic table. Unfortunately, I didn’t have the wonderful sun shining in the background, like I had for my sister’s shot. This was a quick test but as you can see there is an improvement in the after image. The light was cast more evenly across her face. Catchlights were created in the eyes which are key to good portraiture and shadows were eliminated under the chin.
