Photographer Drew Gardner has been a photographer for more than 30 years, and since 1999 he's worked mostly in the commercial world. Following a recent move into 360-degree imaging, he accepted a commission from British newspaper The Telegraph to shoot a gigapixel image of the queen's birthday parade. Earlier this week we spoke to Drew to learn more about how the project came together.

Following a career working in local and national press, I decided to move away from newspapers and into commercial and advertising photography, in 1999. These days I shoot extensively for magazines around the world, so the commission has to be something really special to entice me to work with newspapers again.

When I was asked to shoot a gigapixel photo for the Daily Telegraph, it was a trip down memory lane for me in many ways, but with the latest technology so I leapt at the chance. I was approached about two weeks before the event, and I spent many hours working out the sequence of events and the best position to place the camera.

I work with a wide variety of gear but this occasion seemed a perfect opportunity for a medium format camera, where ultimate resolution would be very useful.

'The final image doesn't represent one moment, but rather many different moments'

I like shooting gigapixel photos to record events. The final image doesn't represent one moment, but rather many different moments. This provides a better overall feel of what it was like to be there. When I say many different moments, the final gigapixel image is made up of more than 110 50 megapixel images, shot on a Fujifilm GFX 50s with a 250mm F4 lens. The result is a 2.3 gigapixel file.

Drew Gardner has been a professional photographer since 1979. Based in the UK, Drew's work spans local and national press, and commercial photography for clients including Manfrotto and Suzuki Motor Corporation.

I love the Fujifilm GFX 50S. It really suits the way I shoot medium format camera, and it weighs less than most DSLRs. Image quality is stunning and it has proven very reliable.

What I really like about the GFX is its high ISO performance. Even though the light was excellent I shot at ISO 1600 to allow me to stop down to F11-16 for better depth-of-field. To move the camera I used a Seitz VR drive motorized head - the same head that I use for all my 360 degree still images, too.

I’m a huge fan of Brian Storm of Mediastorm who is a great advocate of the use of audio and this was the perfect occasion to record ambient audio of the event with a Zoom H2N audio recorder. Audio is all too often overlooked and yet it is a very easy way of adding another valuable dimension to a gigapixel or 360 panorama image.
