Photo People…
February 7, 2005
Hmm, here’s a question. It seems that my new camera does a resolution that when resized to 25% of it’s original size, it’s 648 x 486. My gallery currently resizes photos to 640×480 for their normal, standard-viewing size.
I’m wondering if I should change it so that the photos are done at 648×486, because resizing to 25% original size could possibly produce a better resized image, as it’s exactly 4:1 instead of 4.05:1. I’d think that sampling exactly four pixels down into one would just be better and less likely to induce moire.
Thoughts?
You’re absolutely right, and it would help image compression as well. Wonder why your camera uses such an odd ratio? Non-standard CCD implementation?
Not sure why it uses that exact resolution. Here’s the camera: http://www.nikonusa.com/template.php?cat=1&grp=2&productNr=25513
Also, Nikons seem to always (in my experience) use true 4:3… So maybe they were going for some specific megapixel target or something. Not sure. The images look generallly good, though.

If you dont have time don’t worry about it! Thanks :)
i dont know alot about this stuff, but that would make sence to me from a math stand point.
