From a lazing lioness in Kenya to majestic waterfalls in Iceland: The remarkable photos that will have you itching to book a holiday

·        Former investment banker Andrei Duman documents his passion for travel and nature through photography

·        His works include a lioness relaxing in a tree in Kenya and a house filled with sand by wind storms

·        He says: 'This world that we live in really is an amazing, vibrant and beautiful place' 

Travel photographer Andrei Duman's office has not always been this beautiful. 

The former investment banker spent years working in finance in order to fund his real passion, and the self-taught photographer, who has visited over seventy countries, has no plans of stopping yet. 

'My career has been split into two parts: by day, I've worked in finance, but my true passions are travel and photography, and I've devoted myself to traveling as much as I can,' he says.

'I want to see everything: the more outside my everyday or off the beaten track the better. The further away from the big city and wider open the space, the more I'm drawn to it. I want to see how people live, what they experience on a daily basis, what they eat...  

'I think we all should be exploring more, wanting to find out what is over that hill or in that canyon - even exploring our own environments in a new way. 

'I have learned more life lessons from my travels and meeting new people than through any other way and I want to see as much of this planet as I possibly can.  

'This world that we live in really is an amazing, vibrant and beautiful place, full of amazing things to explore and absorb and I think we all need to get packing.'

Here, MailOnline Travel showcases a selection of the photographer's best images, taken from around the world.
