matthew saville: Yeah, can we get more effort put into the whole quiet operation thing? I'm really really sick of being out in the wilderness where I think I've finally found the peaceful solace of isolation, ...and then I hear that damned beehive sound approaching me. I will throw a stick at the next drone that comes too close to me, if it is in an area that I know to be illegal to fly in the first place.

Silence is golden.

Hey Matt, probably a good idea to wait till you find out that the drone you killed with your vengeance stick was being operated by a ranger in the forest service doing a survey of the local area.

Best not to flash to anger and remedy your grumpy self by destroying someone else's technology.

How would you like it if someone surprised you and started the conversation with, "Hey, you takin' pictures of MY WIFE??? What the frack, buster," then slammed your new Nikon 850 into the nearest rock formation?

Are you willing to spend 400% data space on every shot just so you "might" need to refocus a shot later?

Or would you like to have a picture with 400% of the surface area?

Oops. The Lytro does nothing to solve the "moving camera" form of smears. And those are MUCH more common.

But good IS systems do a lot to improve those.

The author, Uwe Steinmueller, speaks better English than you speak German, his native language. But still.

These images, as do other samples I've seen, seem to have 2 or three focus zones at maximum. The most I've seen in a sample is 4 focus zones.

On article Just posted: Printer Primer Part 2: Print workflow (36 comments in total)

The chestnut of specifications for highest quality printing is this:

"300 dpi". But how far can you bend that?

That's a rule of thumb carried over from dot screen printing in which 300 actual printing dots per inch is about the maximum any mechanical printing process can reliably achieve under perfect conditions.

At 12" viewing, a 4 x 6 print crosses 18° of retina. 50 line pairs per degree is approximately the human limit. Meaning at this distance, an 1800 pixel-wide image will look as sharp as can be. And it will use the full 300 ppi.

You can resample an image to any size and print out a series of the same image at different pixels per inch. Somewhere around 200 ppi, at standard 16-18 inch viewing distance for a letter page, more pixels won't add more appreciated detail.

The National Geographic's images are about 180 dpi. You'll get shots that sharp at 200 camera pixels per running inch of print. Meaning your 18 MP cam's images will look max sharp at about 25 inches big!
