Ms Robayna said on X that Liz “was not only a phenomenal photographer, she was the best human and the most wonderful daughter and big sister we could ever have asked for”.
“No-one could have fought harder for life than she did,” she said.
“There is a gaping Liz-shaped hole in our lives that I am not sure how we will ever fill.”
Ms Robayna offered her thanks to those who helped the teenager fulfil her dreams in her final months and those who liked and supported her work, adding: “You ensured Liz’s last two months were her very best. She flew high until the end.”
She asked people to share one of Liz’s photos in tribute and also to support the family’s mission to fund research into desmoplastic small round cell Tumour, which has no charity specialising in the disease in the UK.
Just a few weeks before she died, Liz had worked with one of her photography heroes, Rankin, at a photoshoot with professional models.
After the shoot model Fifi Anicah said the pictures the teenager took were among some of her “favourite pictures of all time”.
As part of her bucket list, Liz also went on to photograph comedian Michael McIntyre, circus performers, the Royal Ballet, models from the Storm Model Agency, the London Air Ambulances from a helipad, hotel doormen and the red carpet at the MTV Europe Music Awards.
Only last week she attended an exhibition of her work hosted by British Land and Getty Images in London.
