Misc Weekend Pics
I got to fly several times this weekend, and with the fog in and out, had had decent luck.. I compressed them, maybe to much, but oh well, can't wait an hour for the page to load right?
All pics taken with the pencam x on a SS. I am using the high setting, interoperlated mode I think.. Does that give me any advantage over the actual MP setting?????
This is the "Blue Bridge" crossing the Columbia river at Kennewick, Wa

Thanks for the kind words..
When I flew at the river, the SS started some conversations, and one in particular, was with a nice fellow with a camera around his neck.. We started talking about picutures and such, and ends up he learned how to fly licensed aircraft in walla walla in 1941! I got his email and sent him some pictures... He was so graceful and full of wisdom.
Thats part of what I like about this hobby, it is a conversation starter and you meet so many people that you would normally just exchange glances as you were passing by.
When I was finished flying, I talked to a few others that might have been in the pictures and got their emails as well.. A kyaker, a mother and son on the dock, etc... Without the plane in hand, they would probably be afraid to hand out their email, but when I explain how the plane/camera works, they are suprised and feel like it's their lucky day! hehe I send them compressed photos of themselvs and if they like them, I will send the full untouched version. No charge for this, just spreading the joy.
If they want a glossy printed or framed, or call me up for a planned shoot, thats a different story.
Any opinion or fact on the interoplated 3.1mp vs. imager 2.1mp?

interpolation (fake resolution)
Easy answer: stay away from the in-camera interpolated mode.
Read on if you are the inquisitive type.
There is absolutely no advantage to in-camera interpolation, other than marketing.
Interpolation (resampling up) is nothing more than adding pixels to an image using complex algorithms that make the image bigger. Even the very best algorithms (ie fractal) cannot match a picture taken with a higher resolution imager.
The only reason to use interpolation is to print an image larger than it's physical size allows (eg. 8x10 from a 1.3mp image).
You should use software to upsample the image to maintain density (this gives better output than the alternative of printing the image at extremely low dots per inch.) Do this with a nice photo editor like Photo Shop or Paint Shop Pro.
(Example: printing a 1.3 megapixel image (1280x960) at 8x10 inches gives a resolution of ~120 dots per inch, unacceptably low.
Resampling up to ~300dpi gives a smoother looking image, but no more detail)
Bottom line: you cannot add detail the sensor didn't capture.

Yup, what Steve said. Better to do your own "interpolation" via PhotoShop or whatever..
For what it's worth, I had a couple 8x10's printed today from the 2048x1536 (interpolated) pics I shot with my PocketCam X over the weekend..I was pleasantly surprised. They came out very sharp, looked as clear as any 8x10's I've ever shot with film..this little camera ROCKS for the price.
I just wish I had some colorful subjects to shoot like yours..very nice pics, sir!

Usually, in-camera interpolation is just a bad sales pitch. They can then call the camera a 3MP camera when it is really a 2MP.
It doesn't add detail. It just consumes more memory (less pictures you can take), and probably slows down its writing to memory.
Desktop software can do as good a job, if not better.
I had printed out an aerial shot from my Canon S110 that was interpolated up to an 18" x 24" print using Genuine Fractals. It looked good. Not great, but good.
If you don't interpolate and print an enlargement, then you may see the pixels.
