Evelyn McCullough was suffering from terminal cancer when she passed away at the weekend.
She was given the devastating news last April that she had Pseudomyxoma Peritonei, an appendix cancer which is now believed to affect at least two people in a million.
The Portstewart lady had been charting her moods and progress through photography of the north coast.
There was a huge response to her inspirational book about living with cancer.
