Liz Hatton, 17, from Harrogate, was pictured being hugged by Kate at Windsor Castle in October after being invited to take pictures of the Prince of Wales at an investiture.
Liz began a photography bucket list appeal in January after being diagnosed with an aggressive desmoplastic small round cell tumour and given six months to three years to live.
Liz’s mother Vicky Robayna paid tribute to her “incredible daughter” and the kindness, empathy and courage she showed, saying “she flew high until the end”.
Her death at home early on Wednesday morning had left “a gaping Liz-shaped hole in our lives that I am not sure how we will ever fill”, she added.
Vicky announced on X: “Our incredible daughter Liz died in the early hours of this morning. She remained determined to the last.
“Even yesterday, she was still making plans. We are so very proud of the kindness, empathy and courage she has shown in the last year.
“She 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. There is a gaping Liz-shaped hole in our lives that I am not sure how we will ever fill.”
Vicky 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, under the hashtag #LizHatton, 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.
Vicky has set up a fundraising page at justgiving.com/crowdfunding/vicky-robayna with a goal of raising £100,000.
Kate, who herself was treated for cancer this year, and William, in a personal message earlier in the autumn, described Liz as a “talented young photographer whose creativity and strength has inspired us both”.
Liz was joined at the Windsor Castle investiture by her mother, stepfather Aaron and brother Mateo.
Following the news of Liz’s death, the Prince and Princess of Wales said in a personal message posted on their official social media accounts: “We are so sorry to hear that Liz Hatton has sadly passed away.
“It was an honour to have met such a brave and humble young woman.
“Our thoughts and prayers are with Liz’s parents Vicky and Aaron and her brother Mateo at this unimaginably difficult time.”
As part of Liz’s bucket list, she 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, the red carpet at the MTV Europe Music Awards, and joined acclaimed British photographer Rankin to lead a fashion shoot.
Rankin previously paid tribute to her skill, telling the BBC: “The photos Liz has created… are really sophisticated images… She understands that it’s a creation.”
He added: “It’s been a real privilege actually, watching her. I’ve been pretty redundant. She did exactly what an experienced photographer would do. Got involved, gave people directions, almost became the captain of the ship.”
Liz fulfilled what her mother described as her “biggest wish”, spending two days with Los Angeles-based portrait photographer David Suh, who flew from the US to work with her.
Her project culminated in her own photography exhibition in London this month, showcasing her work.
Ms Robayna said on X at the time: “Liz had her very own exhibition last week, the perfect culmination of her incredible achievements.
“As I walked around looking at her pictures, thinking about the circumstances many were taken under, I was more in awe of her than ever.”
But Ms Robayna also revealed two days ago how Liz had become increasingly tired and how they were due to be celebrating Christmas early as a family at the end of this week, adding: “We know our time is short now.”
The former Harrogate Grammar School student launched her own website devoted to her photography.
It tells how she began taking photographs as soon as she could walk, saved to buy her first “real” camera aged nine and, at 11, chose her secondary school because they offered photography as a course.
She took GCSE photography and began her A-level to refine her skill.
Taking photographs also helped Liz cope with her constant pain.
“Every time she picks up her camera and focuses on new and exciting shoots it helps to distract her from the constant pain that she feels every second of every day. When taking photographs, the rest of the world doesn’t seem to matter as much,” the site said.
