Exposure stacking

About a year ago I photographed a model of Newcastle University that sits in the King’s Gate Building. The model shows the city centre, with the University’s buildings in white. It’s a fantastic model with a huge amount of detail. The shoot had it’s challenges, in particular ensuring that the shots were in focus over the whole image. This was difficult because of the very different focal lengths for some of the shots, such as the one shown here. The solution was a technique called exposure stacking. This involves taking a number of shots of the same view (using a tripod of course) but changing the focal length each time to ensure the scene is sharp in all parts. The different exposures are then combined together in Photoshop. The end result is a very deep depth of field not easily achieveable in one shot. To find out more there is a great article here: exposure stacking. And more shots from this project can be viewed in the archive here.
