aspect ratio G3

[anthony dibiase]

Could anybody please tell me if there is a way to change the aspect ratio,

on the G3. I am looking to print 4x6 pictures and when I go to resize them in ps6 I get a size of 4.5x6. I there any way to change this to get an actual 4x6 picture without clipping or a white border.

 

[Bernie*]

Not sure about the G3. My Nikon has a 2:3 setting. Maybe you have something like this.

i'm pretty sure that there is no way to change the aspect ratio on the way the g3 takes pictures. the only way to get perfect 4x6's or any other size prints is to crop them.

You cannot change the aspect ratio in the G3. To resize the photo use Photoshop Elements or another program, choose the resize or crop option and bingo. If you have them printed in the original format on 4x6 the photolab will crop for you.

The aspect ratio of the Canon G3 is indeed 1 by 1.5, and thuis the same as that of a 35mm of 6x9 cm camera. So, the print size of 4x6 works perfectly. All you have to do is resize the image size. Be careful not to resample the pixel count as that will degrade the image in case you want to print a larger version of it.

 

[Jojosung]

correct me if i am wrong here... 1 by 1.5 and 6 by 9 and 4x6 has the same aspect ratio of 2:3, but the picture output size of G3 is 2272x1704, which is a 4:3 aspect ratio...

how is 2272x1704 a 2:3? the math do not works here!!!

jojosung is correct. The aspect ratio of the Canon is 4:3 (or 3:4). I have just about eliminated the 4x6 from my "portfolio". I have gone to 5x7's mostly and it requires VERY little cropping to print. 4x6 was made popular by 35mm. I no longer "think 35mm" and hopefully that explains why 5x7 is pretty much my minimum print size. Of course, if you are willing to give away part of your image, then 4x6 is easy to do. I came to digital from 35 mm (that comment probably applies to most of us) and it took awhile before I became accustomed to the 4:3 aspect ratio. After a while, I came to PREFER 4:3.

Just an opinion, of course.

[david cago]

I stand corrected ! ! !
With egg on my face, because I am a mathematician as well.
The ratio is 1:1.333-etc.
You can make 9x12 inch prints.
Or 4.5 x 6
or 5.25 x 7
or 6 x 8
or 5 x 3.75
or 4 x 3
or 12 x 16

Unfortunately, no. The native aspect ratio is determined by that of the CCD.

If you want to print primarily 4x6, you'll have to adjust your thinking to imagine a 'dead' margin of 6% or so at the top and bottom of the frame when you're composing a shot. Then, when you're ready to print, go into Image\Canvas Size in Photoshop and change the height to 1515 (assuming you're shooting in Large mode).

I know there are others that will argue the merits of the 4:3 aspect ratio most consumer and prosumer cameras use, but I really do prefer the wider "feel" of 35mm's 3:2 format. Perhaps when HDTV, with its 16:9 AR, becomes more prevalent, digital camera manufacturers will finally see the light ("Wider is better")

Actually, when more pixels are commonplace, cameras will probably go square like many pro film cameras. Then you will select the bit you want to suit the shot. And of course a lens works most efficiently with a round picture and square is nearer to that than oblong is.

Whether round or square, when pixels go for peanuts, we won't have to turn the camera for 'portrait' shaped shots.

[G. Lentz]

You have valid points, but I'm thinking not, just because we'd then be burdening the average consumer to think composition (heaven forbid!) before they shoot, and consumers are what these non-pro cameras are targeted at.

I at least wish these things would come with a menu-selectable reticle overlay to assist in composition with the LCD. Or, maybe just drop the unused (whatever that may be) regions to 1/3 intensity.

This isn't rocket science, and would be a no-brainer to implement in firmware.

Agreed. With digital cameras going 'mainstream' and film users moving across to digital all those used to APS film (with its HDTV setting) will think of 4:3 as very 'square'. In both meanings of the term.

3Mpx/4Mpx is becomming commonplace but is essentially overkill for the 6x4, 7x4 film 'mainstream' users*. Mainstream users are likely to select smaller image sizes rather than buying an expensive CF card.

Hence I can see a need for 1800x1200 (C) and poss 2045x1150 (H) sizes in the firmware.

Thoughts?

[S Crook]

As long as lenses and their image circles are round, then the optically most logical format will be square (well argueably round even -- akin to the science joke about the spherical cow for optimum milk production) but astheticly, rectangular tends (most would argue) to be more pleasing to the eye; 4:3 makes a good comprimise, but due to 35mm people are used to 4x6 (3:2), a less efficent use of the optics.

The ancient Greeks would have argued for a Golden Rectangle 1.62:1 based on the mathamatical constant Phi, but they didn't have photography in 300 BC.

HDTV is even wider, 16:9 or 1.78:1 but with these the weight and size of the camera and the optics will be greater for the same number of useable pixels than the 3:2, 4:3 or (best pixal to weight ratio) 1:1, so I expect 4:3 is here to stay.

Hi Anthony,

i understand your frustation. i went through it myself about a month or so ago after i first got my G3 and wanted to have some prints made by photo services. but it is really quite easy to crop photos to the exact size you need in Photoshop Elements, LE, or Photoshop for that matter.

all you need to do is activate the CROP TOOL. once you activate it, input the dimensions you want for height and width (i.e. 4x6 or 5x7 or 8x10 or 11x14 or whatever you need). then expand the crop tool on your image till it is at the maximum size your dimensions will allow it to go. you will notice that some part of your image will need to be cropped to get it to the precise size you want it to be. so then just move the entire expanded crop box around till you find a suitable composition for your image. then crop it. save the image as "XYZ4x6" and you will know that that particular image has been cropped for that particular printing size.

oh, and don't even bother with worrying about inputting any PPI numbers. they are really not even necessary by any of the photo printing services.

and just experiment by taking an image and cropping it into various different print sizes. afterall, you might decide that one of your 4x6s would make a nice 8x10 or 11x14.

Good Luck!

A while ago, I asked a similar question about aspect ratios:

http://forums.dpreview.com/forums/read.asp?forum=1010&message=4976796

Essentially, although a true 3:2 mode would be great, I would have been happy just to get some digital crop (or frame) marks on the display to help frame the shot. That is, shoot the frame as a 4:3, but by having digital crop (or frame) marks on the screen, I can frame the shot so when I crop in the software, the job is easier since the subject will be well positioned in the shot. Please note that I do not imply that the crop marks are recorded in the image, just that by proper positioning, it makes cropping in the software easier.

Of course, not being patient for canon, I suggested drawing the digital crop (or framing) marks on a display protector. Another user (mango) created some files that can be uploaded into the camera to see where the crop marks are.

Essentially, you should try to avoid placing any object you want in the shot within 2mm of the top and bottom of the display.

Cool. But here's a thought:

With APS people are used to seeing the crop marks on the index prints so how about showing corp marks on the in-camera index prints (the 3x3 view). This would allow people when choosing shots for direct-from-camera-printing to also choose 4:3, 3:2, H, C formats.

We are now getting in-camera editing of videos so why not in-camera editing of printing formats? To me this is a natural extension to DPOF etc.

Hi Paul,

I am really glad that you took the time to respond to this posting. I have been using Photoshop Elements for a couple of months and did not realize the usefulness of the crop tool. After reading your comments, I went back to Elements and played with the tool until I could follow what you were saying. For me the Elements instructions and help files were not complete enough for me to understand how to use the tool. Your instructions did the trick, and I will be using this tool a lot in the future.

You're Welcome Gordon.

i agree with you that it is not easy for us Photoshop newbies to know how to use all of the various aspects of Elements without some help. i was at first trying to make proper size images by using the marquee tool and also by resizing the image and worrying about 300 ppi and all that stuff. but eventually what i did was to go and visit the printing forum here are DPReview and some of the real experts gave me the good advice which i am now happy to pass on to you or anyone else who is reading this for that matter.

i think your average photographer really needs this info because eventually everyone will want to make some quality prints of their images and this is certainly and easy and effective way to get precisely what you want.

so I expect 4:3 is here to stay.

Not necessarily. While most "prosumer" digital cameras have 4:3 aspect ratios, DSLRs like the Canon EOS 10D almost all have 3:2 ratios. I suspect it has something to do with trying to mimic real 35 mm or compatibility with existing 35 mm lenses, but otherwise I can think of no reason why the Canon G3 and 10D should have different aspect ratios. Go figure.

 

[Jiri Kripac]

I crop the images myself to the correct aspect ratio using a freeware JpegCrops.exe that you can download from ekot.dk/programmer/JPEGCrops. It is an invaluable tool when you need to crop a large number of jpeg images to a certain aspect ratio. It also does lossless cropping of jpeg images, i.e. it works directly with the jpeg data and does not recompress the cropped images that would cause quality loss due to jpeg recompression.
