The recorded image measured 5184 pixels wide and 3456 high, as shown in the Image Size window of Photoshop, To find the length that the image needs to be for the subject to look normal you multiple the recorded length by the anamorphic factor - in this case 1.33x, With the width and height dimensions unlinked you just enter the new width dimensions. Different is something I value, though obviously good different rather than the other. In which direction, vertically or horizontally? i haven't read all the comments, so may have missed something answering my question(s)?, but. These bars simply fill the portion of the screen unused by the film. The design process is based on a progressive method, as shown in Fig. 1.33x vs. 1.55x Anamorphic | Ratios, Specs, Focal Lengths, & Effects If the finishing resolution is close to the capture resolution, this means that horizontal detail will be less resolved than vertical detail. TEST B - Rear Versus Front Anamorphs The second test we shot is a comparison of rear and front zoom anamorphs - the optical element in the lens that squeezes the image. Especially at 24fps, classic frame rate. In fact, horizontal resolution can be reduced with an anamorphic lens as the aspect ratio is too high. Obviously, these blue lines are more prevalent in lenses that have the anamorphic cylinder at the front of the construction, and much less obvious in those that place the cylinder at the rear. Ultimate Cinema Lens Test Library 2.0 3. Once you crop that 4K image to an anamorphic format, such as 2.39:1 for example, you end up with footage containing far fewer pixels. Or, in other words, when imagining the sensor to be cropped vertically or when imagining the sensor to be expanded horizontally? This diagram shows how different popular projection formats compare. "all out-of-focus details are reproduced with an elongated shape that exaggerates the degree to which things are out of focus. It does actually modify your effective focal length and aperture.
