Acorn becomes oak tree in timelapse video

(CBS/Reuters) Plant lover and filmmaker Neil Bromhall collected an acorn in September 2010 and planted it next to a mature tree.

He then programmed his Nikon D300 camera with a 55mm macro lens attached to take exposures every two hours over the next eight months.

Bromhall says the acorn split soon after it was planted and continued to split during the winter months.

In January, he says the root began to grow with the first shoot emerging the following month. The shoot broke through the soil in March and the leaves formed between March and April.

Bromhall is an experienced and accomplished nature cameraman and photographer. He has worked for many years for the BBC's Natural History Unit in Bristol, UK, specializing in macro and timelapse filming. He won an Emmy for his work as a cameraman on Sir David Attenborough's "Private Life of Plants".

With his website, Bromhall says he is using his spare time to continue indulging his passion for plants and photography. He says his database is designed to "encourage youngsters as well as people with learning difficulties to take up gardening."
