Photography tips
How this image was taken
For this shot at a 12 mm focal length, an aperture of f/14 was chosen to ensure deep focus from the foreground to the rainbow. The shutter speed of 1/320 s at ISO 400 allows for sharp architectural details without motion blur.
- Choose a small aperture of f/11 or higher if you want both architectural features and distant elements like a rainbow to be in focus throughout.
- Use a short shutter speed to capture the delicate color gradients of the rainbow clearly.
- Pay attention to precise camera alignment when using a 12 mm wide-angle setting to minimize converging vertical lines on buildings.
