Image Aspect Ratio

'Getting to know the 3:4 image aspect ratio of half-frame portrait frame cameras - Part II'

While most of us take pictures in the landscape or horizontal format, half-frame cameras are inherently designed to capture images in the portrait or vertical format. Half-frame cameras capture images in the 3:4 aspect, an uncommon ratio, seldom mentioned except maybe when talking about images that are a bit too fat, a ratio that is difficult to work with, or image frames that are difficult to fill effectively.

The film format for half-frame cameras is 24x18mm on a regular 135 film, which is half the size of a normal 35mm frame measuring 24x36 mm. With a half-frame camera, one can shoot and capture twice as many images on a standard roll of film - 48 shots on a 24-exposure roll, 72 shots on a 36-exposure roll, and so on.

Holding the camera horizontal with both hands is also the norm for taking photographs. The camera will normally rest in the grasp of the right hand with the index finger used to press the shutter release. On a more complex camera, the left hand will normally be used to focus the lens and other adjustments such as aperture and other settings necessary for the correct exposure of the shot.

On a simple point-and-shoot, the left hand will just be a support to hold the camera steady. With half-frames, this is the same stance you will be holding the camera with, the difference being that your image will still be shot in the vertical frame, rocksteady images in 3:4 image aspect ratio.

The scanned images, which was done by the processing lab, were post-processed on Olympus Viewer 3 (OV3), and tweaked with edits including Auto Tone Correction, Brightness & Contrast, Gamma, Hue & Saturation, Sharpness & Blur, Unsharp Mask, Noise Reduction, and cropping of the doubled-scanned images into single images.
