Is there a way to set the aspect ratio in a Canon 350D?

As a corollary I would be thankful if anyone can recommend somewhere that explains simply the whole subject of aspect ratios.

Thanks.

The sensor is the aspect ratio of the size it is, it cannot be changed.

You can crop the picture afterwards in any picture editor to any aspect ratio you like.



7D, 450D | 17-55, 10-22, 55-250, 50 1.8, 580EXII | YN568II | YN622 x3 | Magic Lantern | (Still) Jonesing for a 70-200 2.8...
Turns out a gripped 7D + 622 + 580exII + 70-200 2.8 IS MK2 is BLOODY HEAVY! Who knew?!!

Thanks. Not sure this helps, perhaps I asked the wrong question:cry:

The problem is that when ordering a print the sides of the picture are cut off and the printers, (Apple) said that the aspect ratio should have been 1.25 and not 1.61 which it apparently was. The solution, they said, was to order a larger print. Does that make sense?
Cheers & thanks for your patience.

If you order 8 1/2 x 11 inch prints (just as an example) from images made with your DSLR you will have parts of the image cut off. That is simply because the shape of the sensor (and final image) is a different length x width than the print.

As above, I don't think you can change it in camera, you just have to crop the image to reflect the proportions of the print you want. Or order an 8x12 print.

The primary option would be to crop the image to fit the desired image size.

Thanks for this. So am I right in saying that what I ought to do is when shooting, for example, a group photography to allow plenty of extra space either side of the group? Sorry if this is a bit dumb but I do not want to make the same mistake again.

If you know you are going to need to crop in a particular way to fit an image size you know you are going to print to, then yes, absolutely bear that in mind when shooting and frame accordingly.

Yes, always consider output. Especially if shooting something where an 8x10 is a likely outcome. Play with the crop tool in your software to get an understanding of what has to be removed from a 2x3 format to get an 8x10, or other shaped print. (focus on shape rather than size).

The default aspect ratio (unchangeable) for the 350D is 3:2 (or 1.5 to 1) so yes you will lose some if you print an 8 x 10 for instance since the 8 x 10 is 10/8, 5:4 or 1.25 depending on how you express the ratio.

If you use software, like the Digital Photo Professional that came with your camera then you have a cropping tool which offers a wide range of choices one being 4:5 or 5:4 which is the aspect ratio you are after, the two numbers being portrait or landscape orientation; 5/4 = 1.25. Once cropped you can then save the modified image (preferably under a new name) in a size appropriate to the print process.

I've attached a screen shot showing the aspect ratios from the current version of DPP. If you should chose to use it I suggest you install the original, then do the upgrade to the laetst and greatest. It has changed substantially since the 350D has hit the street.

I really find this confusing as basically I can not tell whether or not all of the photograph will be printed that I order! This has happened to me quite often and I wish there was some way of knowing before ordering prints. The latest example was a group photo where the people on both left and right were completely cut off although as far as could see there was no reason for them to be. I have now had to order a larger print than I wanted—comes expensive when ordering 8 copies!:(

Thanks for this, I use Apple’s Apperture software.

The easy answer is to frame more loosely so that you can accommodate any shape (or size) print. If you fill an image in the viewfinder edge to edge then 8x10's will not be an option for you. But as I said, play with the crop tool. Take a full 2x3 ratio image, select the crop tool at 8x10 and drag it edge to edge and you will see what you are going to loose. Once you do that with the various sizes you might want to print you will have a better feel for it.

When printing, there are two options.

Either cut off space from left and/or right when the paper is more square than the photo you sent in for prints.

Or fit the full photo and instead add white above/below to fill up to the full height of the paper.

A good print service should be able to support either of these two options.

The other option is that you create (cropping left and/or right side, or expanding with white above/below) a source file that has that 8x10 aspect before sending it for printing.
