Product photography is not just about the product. It's also about the environment in which the product is placed.
This image was originally destined to have a dark purple background but during retouching it was deemed to look more striking with a grey background.
Now here's he interesting part!... Two images were posted on Instagram and Facebook and he viewers asked which background they preferred: the grey (above) or the purple.
On Facebook, there was a 100% preference towards the grey background.
On Instagram, there was a near 100% preference towards the purple background.
The main difference being that the Facebook followers are mainly 'Joe-Public' and the Instagram followers are mainly photographers!
So it seems to me that, as photographers, we do indeed so the world differently and this is a VERY important lesson to learn when you're a product photographer!
