About me:

I've been in love with photography for over 40 years.

My favorite form of photography is macro, and much of my gear is of my own design.

I've done professional photography on and off for over 20 years.
Taught 8 years at Midwest Photography Workshops.
Designed 3 scientific digital cameras and 6 lenses.

Author of mImage and (coming soon to the App Store and Google Play) ColorForEveryone.

  • It looks like the batteriser guys just revisited the article and copied and pasted the same fake "third party" saying "they did an interview. It answered all my questions, here's a link" response ...
  • Just what you did, and it turned out very well. Thank you for sharing. But, what do you do if you want a 360 stereo pair, or even 360x180 stereo dome, say for an Oculus Rift or Google Glass experience?
  • You've never had the experience of Sony taking 6 months to fix a $12,000 dockable professional video camera, I take it. Waiting for parts from Japan. Didn't work, ordering more parts from Japan. Di ...
  • Totally. They were made before digital photography. The 28mm f1.8 Ultra Micro Nikkor was designed to 850 line pairs/mm resolution. That's 1.1 gigapixels on an APS sensor. Modern optical testers ...
  • That's the reason that Sony's camera division will do nothing. Sony Semiconductor (or whatever their name of the month is) sells more sensors to Nikon, Fuji, Pentax, etc. than they do to Sony ...
  • Hardly. The top layer of a Foveon sensor has about 1/4 the well capacity of a more conventional sensor design, and a higher noise floor due to the differential read circuitry. Put those two things ...
  • Glad you enjoyed. Unfortunately, the CFA is underneath the microlenses. It might be possible to get rid of the microlenses without bothering the CFA, but you can't go the other way around. I'm dead ...
  • Dear spammer, I suggest you stop creating new account after new account. You will never sell your architectural CAD or 3D modelling services to anyone in this group.
  • No. Stripping them from the camera would drop sales dramatically, triggering an enormous rise in the price. So, I'd save a lot of money buying a more conventional camera that I would simply only ...
  • Making primes specifically for APS doesn't net you much in the way of a size or cost savings until you get pretty wide, like the 10.5mm Nikkor or the 14mm Pentax. Not really. A wide angle prime is ...
  • Replied in A real pain...
    Which means you need the manufacturer's noise mapping software in order to complete the operation. :( Anyway, thank you Iliah, for that very valuable insight into how the business works.
  • Do we? Here's what the National Fire Protection Organization has to say about that. (sorry, the Googleized link won't paste properly. Google the first line of the quote if you want to see the source) (1) ...
  • Replied in Indeed...
    True. It's probably impossible to measure 60Hz emissions on a cell phone... ...without violating one of my patents. ;) True. Of course, the meter in the video was equally as useless...
  • You should read your own links. That paper says (1) It is not currently known whether magnetic magnetic fields originating from induction hobs represent a health risk.
  • Replied in A real pain...
    Yes. I've done it. I also put together a business plan involving it a few years ago. But I felt that risks were too great for the returns. Nothing like that. The infrared blocking filter sits in ...
  • No. Nor do I run tests on how many pingpong balls it takes to fill a garage, or other similarly ridiculous things. Magnetic field is proportional to current through wires and the number of turns of ...
  • About 5 uTesla at the cook's position. That's 50 milligauss, 10x the field measured in that silly video. And still utterly harmless.
  • Intouition.
  • No. Exactly. Lytro is "repurposing" themselves. Lightfield cameras have crashed and died, but lightfield displays are grabbing big media attention and investor dollars, because of their potential ...
  • Nope. Just keep the switching frequency of the device below 10kHz and the FCC doesn't require testing. That's why so many lighting products whine. Well, if the article's claims were true (that the ...
