Fritillaries in Focus
The flowering of Snake's Head Fritllaries in North Meadow at Cricklade is one of Wiltshire's finest wild flower spectacles. I wanted an image including Cricklade church tower as a focal point as it catches the light a few minutes before sunset. I chose a viewpoint where trees screened the housing estate on the edge of Cricklade. A short telephoto lens (115 mm) compressed perspective, showing dense fritillaries and bringing the church tower into the composition. However, even at f/36 the depth of field was insufficient to get all the flowers and the church in focus. I therefore made three identical frames at different points of focus and blended them using focus stacking software to render the scene sharp from front to back. Each frame required 1.6 seconds exposure time, so a completely windless evening was essential to avoid motion blur.
