Bachelor's Tim and Anna just committed an Instagram couple faux-pas at Derby Day.

Former Bachelor Tim Robards and lawyer Anna Heinrich have posted two very sweet, near-identical pictures from Derby Day with one very amusing difference.

The uploaded images reveal the couple’s differing views on which Instagram filter should be used on what is an almost identical photo.

Look, we all know that depending on the photo, you can be a Slumber or you can be a Gingham but nobody is ever a Hefe. Nobody.

Heinrich seems to prefer the warmer tones of a Mayfair-type filter while Robards goes for more of a Hudson vibe.

The photos may initially seem identical but a quick scan of the background action implies they were taken seconds apart.

The cute gaffe is just another reason why you should always have a quick briefing with your partner before you make a similar post. I imagine such a chat would go like this:

Me: Let's do Slumber at 40 per cent and then a bit of Lux?
Them: No.
Me: .... *sulks*
Them: Okay.

Robards' cooler version did also gain a considerably fewer likes so maybe the proof is in the pudding.

Who are we kidding? We love it all.

The couple met on the first season of The Bachelor and have been filling our social media feeds with loved-up snaps ever since.

Since then they have slowly moved towards a life together but are yet to announce any plans for marriage.
