Photo Forum / Digital Photography / DSLR Cameras / March 20068MP vs 10MP, an informal test
Hi all, I've just placed on DIMi the results of an informal test of upsampling an 8MP Canon 350D image to the same resolution as the 10MP (roughly) Nikon D200. The article is here: <http://www.dimagemaker.com/article.php?articleID=460> Comments very welcome on whether this is meaningful, a load of rubbish or whatever :) BTW a reminder to get your first entries into the DIMi panorama competition for February. <http://www.dimagemaker.com/comps/realviz1stq2006/panorama.php> Cheers, Wayne Wayne J.

You'll begin seeing differences when you compare any of these with some 19-20 MP system like Hasselblad, but then the price is about €17000. I looked at your pictures and at a quick glance I saw no difference at all.

Take a photo with two cameras, one 8 meg, one 10 of a railroad track going to a vanishing point. Take a look at the ties and see which camera lets you see the ties at the furthest point. That will be the 10M camera. -Rich > Whoever wrote what you claimed to have read was an idiot. > Take a photo with two cameras, one 8 meg, one 10 of a railroad > track going to a vanishing point.

And your hands steady enough. Thom Hogan maintains that for the type of shooting many amateurs do, anything over 6 megapixels actually reduces picture quality. Consider this quote from his review of the Nikon D50: "But let's talk about 6 megapixels for a moment, since Nikon seems to have left their consumer DSLRs stuck on this value since 2002. For some time I've been writing "if you can't get a good looking maximum size print out of an Epson 2200 from this camera, it's not the camera that's the problem." Just to be clear, that's 13x19", and I'd say the same statement applies to the newer Epson 1800 and 2400 models. Yes, having 8mp would give you more cropping ability (about 400 pixels in the horizontal axis). Yes, having 8mp would increase resolution a bit (the theoretical maximum would be 12.5%, but in practice it works out to somewhat less than that). Plenty of pros still use D100 bodies day-to-day. Indeed, for the target user of the D50 I'd say that 6mp is about right--more pixels than that actually poses hazards to sharpness when a camera is handled casually." Yeah. Set the camera up on tripod in a studio and shoot test charts, and 8 megapixels will beat 6 every time. Things are a little different out in the field, though. > Plenty of pros still use D100 bodies day-to-day. Indeed, for the target > user of the D50 I'd say that 6mp is about right--more pixels than that > actually poses hazards to sharpness when a camera is handled casually." I fail to see any support for that argument, nor do I can I think of any scientific justification for it. SignatureThomas T.

Seems to me that may be true for full-frame prints; where _I_ see the difference is in crop slack. Make a ten- or twenty-percent crop on the different size images, and you may pass under some threshold of acceptability. SignatureFrank ess > Hi all, > [quoted text clipped - 9 lines] > competition for February. > <http://www.dimagemaker.com/comps/realviz1stq2006/panorama.php> There isn't much difference between 8 & 10 MP but I'm planning to upgrade from 6 to 10 & that should be noticeable. Yes, 6 to 10 is a significant jump, IMO if you need the extra pixels and all else being equal. Cheers, Wayne Wayne J.

I've recently begun printing 13x19-inch and this is pointing out the lack of pixels... as well as my sloppy focusing/steadiness & abuse of wide aperture <g>. >> Yes, 6 to 10 is a significant jump, IMO if you need the extra pixels >> and all else being equal. > > I've recently begun printing 13x19-inch and this is pointing out the > lack of pixels... as well as my sloppy focusing/steadiness & abuse of > wide aperture <g>.

Good God, you want the camera to tell you when you are doing something stupid? Ok that is in the D5000 from Nikon-Canon-Sony that hits the stores in 2013 Of course the Chinese company Snapon had a model with this out two years previously but the US- China trade embargo of 2010 has meant it is not available in the US :) Hey Paul, just keep practicing and you'll work out the kinks. We all have them. Cheers, Wayne Wayne J.

Hehe ... just use the program mode with a "face" on it ;-) SignatureThomas T.
