16x9 vs 4x3

[pcinfoman]

I just got my Canont Rebel XT about a month ago and have noticed that all pictures are in 16x9 format. Now this is good for widescreen action, but I am used to many other camers that shoot in 4.3 format (which is good for web backgrounds and standard printing).

Does anybody know if this is a manditory feature of the camera? Is there a setting somewhere in the camera that I missed that allows me to switch to another format?

All three of the Digital Rebel camera produce a 3:2 aspect ratio image. The Rebel XT was a 35mm film camera and produced a 3:2 image as well.

If you are getting 16x9 images you must have a piece of software stepping on the images AFTER they come out of the camera. I've never heard of a Rebel that produced this size of image???

The 3:2 ratio is standard for DSLR's other than the 4/3rd's system from Olympus and a consortium to produce lens/sensors.

You might want to examine the EXIF data on the file to see the native file size, and if a software application is listed that has altered the image.

One more question, just what size of images are you getting?

Hope this may help.

I do believe you are wrong here. When setting the picture quality, I have 3 options.

3458x2304
2498x1664 and
1728x1152

These are not 3:2 ratios.

They are all 3:2 ratios.

Do the math please:

3458 / 2304 = 1.50
2498 / 1664 = 1.50
1728 / 1152 = 1.50

3 / 2 = 1.50

That is what is meant by the Aspect ratio of this type of specification. The ratio of the longer side to the shorter side of the image as represented by the pixel count of the sensor/camera file output is the Aspect Ratio or format(though format is more for video terminology).

OK, so it is 3:2 then. Sorry for the confusion. Is this a SLR thing then. I used to have digital camera but it was not slr. Anyway, it took pictures with the following resolutions.

1280x1024
1024x768
800x600

Yeah, it's a DSLR thing. Manufacturers have always maintained the 3:2 ratio to make the transition from 35mm film (which has the same ratio) as easy as possible.

The standards for digital point-and-shoots are not so rigid so they come in different ratios.

If you want other ratios, you will have to crop to suit your needs.

Wecome to the boards.

Resolutions of compact DCs seem designed for computer use: 1280x1024, 1024x768 are all typical computer screen resolutions. By that you can view them with no black edge on computers.
