My architectural photography involves a very meticulous process comprised of multiple exposures taken on location, using a mix of natural light, available light and added light (strobes), often over a long period of time in order to create photos that are impossible to make with a single click of the shutter. I composit these images together in post-production, taking the best parts of each exposure. I then apply colour correction, do some retouching and finally add my special finishing touches to create the perfect finished image.
In this example, the left photo uses the available room light, the right photo is strobed and blended. Use the slider below to see the difference:
