Trump would say: Sunset? Fake news!

And this time he's right ;-)

It will probably be not too surprising to some of you that I'm a bit focused (quite an understatement, haha) on food packaging lately.

With this pic I Trumped myself in faking ;-)
I had this plastic blue box which (or should I use the word 'that' instead of which? I never know.) contained mushrooms.

I tried to photograph it with backlight of a candle that was quite a distance (1,5 meters) away. So funny to discover that the result (after lots of takes) looked (kind of, any way) like a plastic fantastic sunset ;-)
When you look closely, scratches in the plastic box can be seen.
I love the surprises of photography :-)

[Saxa van Eijnsbergen]

Very creative! Would like to know what native speakers say of which/that :-) I had a quick look on google, and found the explanation so complicated (for a Tuesday evening after work haha).

In your case, you can use both, but I would lean toward "that " since It's a box containing mushrooms, not just a box.
