Canon G16 and RAW
Dec 29, 2012

It's my understanding that the Canon G15 does multiaspect-RAW, but when I look at the folder all I see is jpg. Am I misunderstanding what multaspect RAW is?

Thanks

The aspect ratio on the G15 is a seperate setting from RAW and jpb. On the func menu you can select 16:9, 3:2, 4:3, 1:1 and 4:5. The next line down lets you select RAW or jpg or RAW+jpg. The next line down lets you select Superfine, or fine, L, M1, M2, or S size. So you need to select which combination appeals to you. Make sense?

I have not tried any of the other aspect ratios in camera.  I shoot the full 4:3 and then crop as desired in post processing.  But I am shooting L size and superfine setting.  I'm quite pleased with the results.  Seems like a pretty versatile camera.

Shooting full resolution using JPEG would be a good idea but the multi-aspect settings behave differently when shooting in RAW mode. The camera still captures the 4:3 ratio image and simply adds a crop window visible in DPP. So you get the on-the-fly cropping without the downside of reduced resolution, and any aspect ratio selected in the camera can be backed out in DPP afterwards. This G15 is an interesting little animal.

Thanks for the further info, Pootie.  That's really about the only way you could do it.  The RAW file is not yet an image,  It hasn't been through the demosaic process yet, and is simply an array of voltages dumped from the sensor photo-diodes.  Until it goes through a conversion process there is no image to crop, so about all you can do is say  "cut here".  :))  I'll have to give it a try and see the window in DPP.  That would be fun.

Does the same when processing RAW images in Lightroom, with the image already cropped at the selected aspect ratio. I kind of like it as I can change the crop later if necessary.

Good to know, I was thinking it might just be a DPP thing.
