Sisters and founders of healthy food business Hemsley & Hemsley, Melissa Hemsley and Jasmine Hemsley, have been announced as Heathrow airport's food Instagram ambassadors.

The pair have shared their top ten tips and a guide for taking foodie images while on holiday in a video on YouTube, and commented 'We love sharing our culinary adventures and over the years have picked up a few techniques for taking great food snaps. We’re excited to be sharing these tips and tricks with Heathrow passengers travelling to exciting destinations, so they too can embrace the food-photo-sharing phenomenon and start capturing creative, vibrant and appetising images themselves that will be a hit on Instagram'.
