Question about aspect ratio #1

Kinda of confused.

I set my camera for 16:9 aspect ratio. Took a couple of shots and imported into Aperture.

In the info tab the aspect ratio is still showing as 3:2

What’s up with that. What do I really have?

Never mind the answer is my camera Canon 70D only allows the 16:9 aspect ratio in live view. That sucks.

Another gotcha is if you shoot raw. The raw file does not have an aspect ratio other than its native one. Need to shoot JPG to retain in-camera aspect ratio changes.

Information regarding aspect ratio on my Canon 70D…

During Live View shooting, you can select the aspect ratio from [3:2], [4:3], [16:9], or [1:1]. The [16:9] ratio is ideal for shooting a long and slender object. Since the human visual sense is naturally broader horizontally, this ratio is also recommended such as when you want to shoot landscapes emphasizing its broadness. Conversely, the [1:1] ratio is effective in drawing the viewer’s eyes to a single point. It recreates the feeling of staring at something, enabling you to emphasize the object.

*This function is available in Creative Zone modes.
*JPEG images are saved in the set aspect ratio. RAW images are recorded with [3:2] aspect ratio information added to the image.

Based on that information, I’m going to bet that if you shoot RAW in live view shooting with an aspect ratio other than 3:2, then when you use DPP to convert to JPG it will honor the desired aspect ratio automatically.  In other words your RAW file is always 3:2, but if you use Canon’s RAW converter your JPG will be cropped as desired automatically.

I think people forget the sensor size reality, a RAW file can only start out as the same size and aspect ratio as the camera sensor, any “in-camera aspect ratio” setting is simply an in-camera crop. Not sure why anyone would want to do that, much safer to crop after (even if in batch) in PP

 

Similarly why the 3:2 aspect in Live View? That is because you are looking at a video feed from the sensor, not a separate optical path via the mirror and viewfinder, consequently the video feed is taken from the sensor data with its aspect ratio….perhaps too difficult (expensive), to make it both take the video feed and crop in-camera…

Hi, Checked EM-5 aspect ratio

I shoot only RAW. My Olympus E-M5 maintains aspect ratio in RAW. I have a smart album that sorts by aspect ratio. Just parsed my library. Also shot some test shots – maintains aspect ratio. I remember shooting with the pany 14mm in 16:9 and working on a 16:9 RAW. I wonder if other Oly cameras do the same. If I set my Fuji X-A1 on RAW  - The Image size menu is grey out. Image size is available in JPEG on Fuji.

Some cameras do maintain the aspect radio with RAW files. My Canon 70D and I think most Canon cameras do not. I know the Sony A7x do maintain the ratio too.

Are you positive it isn’t just the embedded preview is the selected aspect ratio and the aspect ratio is set in the Meta data? Having the aspect ratio in the RAW file would mean a physically different RAW file with its own support requirements which seems a lot of effort on Sony’s part for not much gain…..the test would be whether you can subsequently select a different aspect ratio of course.

Checked Exif data

All RAW Files on Olympus -1:1 = 3456 × 3456 (11.9 MP) in both “pixel size” and “original pixel size”  16:9 = 4608 × 2592 (11.9 MP)  in both “pixel size” and “original pixel size”,    3:2 = 5184 × 3456 (17.9 MP) =  in both “pixel size” and “original pixel size”,   4:3 = 4608 × 3456 (15.9 MP)  in both “pixel size” and “original pixel size” –  the file Size varies with each aspect ratio

Interesting, so no going back in PP then.
