It was bright sunlight to about almost 2 hours before sunset. The tent was in a shade. I tried both from one side and from the back. I did not even try on an overcast day at all. Somebody said it might turn out too blue.
I thought the result was pretty good.
One thing I found was a bigger tent would give you more room to work with. Smaller one is a bit limiting! Oh, they measure diagonally. I bought a 14" thinking 14"x14"14". Nahhh, it was about 12.5"x12.5"X12.5". Lesson learned. Not sure if it was the same in the UK.
