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.

  • Glad I read through all the responses. I was just going to tack a post about the old sharpie trick to the end of the thread. It does work. I've got some lenses I use for especially hostile ...
  • You can't use APS film in a "plain old 35mm camera". The transport mechanisms are totally incompatible. There's no way to feed the APS film through the sprockets on the 35mm camera or engage the ...
  • Because it's rather ugly, speaking both in terms of human visual psychophysics and classic art and architecture (where the "golden ratio" rules). Basically, humans see rectangles. 1.5 is close to ...
  • Well, that's a bit disingenuous. B+W uses Schott glass for the same filters that Heliopan uses it for. Both Heliopan and B+W use non-Schott glass for things like ND grads. http://www.heliopan.de/ " ...
  • Increased smearing, due to an increase in spherical aberration. The effect gets worse with faster lenses. Mike and Lucifer both talked of slow lenses.
  • Like several others mentioned, the big concern is the odd size bottoming tap. The helicoil itself is not a concern. Camera makers routinely use a coil insert in their soft cast-aluminum camera and ...
  • I can remove it, but that also removes any replies to it, like the one where you mention the corrected calculation (and this one where I reply to that one).
  • This is interesting...

    "The Panasonic Lumix DMC-CM1 smartphone boasts a 1 inch 20MP sensor, which is likely the same imaging unit we've seen used by other recent high-end compact cameras like...

  • No, they didn't. They said it's a possibility if they don't secure additional funding.
  • Zeiss said "neutral" bokeh, not "beautiful", so I'm hesitant to give it that first "yes".

  • Replied in Camera Angles
    The cameras are normally pointed at the center of the subject. Low cameras angle upward, high cameras angle downward. 123d prefers the images shot as I described. You'll get the best results with a ...
  • Possibly possible. Google Glass runs a slightly stripped Android 4.4. I've run a lot of serious stuff on it, pattern recognition, image recognition. It would probably run DSLR Dashboard, if I ...
  • Replied in So many ways...
    Unless, of course, you use a CF to SD adapter. There's been a lot of people reporting success with the Eye-Fi in the 7D with an adapter. Remove the metal shields from the SD adapter and you will ...
  • Replied in Dude, you rock!
    I live for openings like that. :-D I did. Very nice work. Very interesting. Can you tell us more about how you did it. Is this small platform laser scanning, or are you reconstructing a mesh from ...
  • There's three things very wrong here. First is the obvious: any relatively sturdy device is cheaper than something so flimsy that it has a woefully short lifetime. Cardboard is what you ship a ...
  • That's only the no-load voltage. When you draw enough current from the batteries to recycle a flash, the lithium cells actually drop to a lower voltage than the eneloops (or any decent NiMH, for ...
  • The numbers are wrong for that. If you look at the battery tables at allaboutbatteries.com (which were basically copied from Duracell datasheets circa 2008) Weight of a full fledged NiMH cell (1) AAA 12g
  • Yes, that is indeed what you are, in addition to the sort of person who makes comments based on videos that they never watched, and then attempts to defend their position with another video that ...
  • They used to, but they sucked. More on that in a second. There are other brands of low self-discharge cells that do come in D http://www.tenergy.com/10107 http://www.tenergy.com/10105?sc=59&categor ...
