The act of capturing images takes very little additional power compared to having it on.   With a Pentax battery, I have had the camera run in continuous shooting more for ~4 hours.   You can very ...

Thats extremely unlikely.   If you are having to rotate a little bit counter clockwise, its likely the shutter press.

My stupid phone snaps... People have their limits, apparently. Oooo!  They Still Have Pizza!   Oh, yeah, cauliflower. Novelty virus home decor? Don't worry, I have crackers ( Yes, these are in my ...

No.   That would be like asking if you should try a Blackberry 8700 when you have iPhone  -  like any iPhone. Blackberry 8700, one of the "hottest phones" in 2006, when the K10D was released.

You are somewhat mis-characterizing the video. There were at least a half dozen times where people of different races and genders seemed perturbed by his "style" of taking their image. Making...

I do a lot of close up photography and stacking where dust and schmutz is more problematic.  Like really problematic.  To the point where I get dust madness then go through the "stages of grieving" ...

If the question is "will the DoF at the center and edges of the frame be the same?" I am thinking not for lenses with high levels of vignetting and / or coma. The blur is not circular as you get ...

If it costs like $20, it might be fun:
720p HD resolution
MP4(H.264) or GIF output
17mm mount compatible
Electronic shutter

The CA, even stopped down, looks really bad.

Round 1:  Planetary observations. Any guesses as to what I was shooting?   :-) Round 2: Mouse eye. This is the tiny sensor from an optical mouse.     The pinkish square is an 18x18 pixel image ...

Exactly! Thank you. Clearly each lens will have a different transmission curve, but I suspect the ones people gush on about are exercising a perceptual quirk. There is research that shows an ...

Its not the thesis, but the methods.  The have successfully "proven" that 12 graduate students, of which 11 are males, mean age 27 years old, possibly from the same lab, think their algorithm is ...

The short answer is "no" - though the long answer may well be vendor specific.  None of the time stamps I have every see are stored with higher precision than 1 second.  Willing to be proven ...

Your lab sounds like a complete pain in the rump.  A $200 flatbed scanner with film scanning capabilities will do as good a job as they seem to be capable of without the excuses.

The retouching forum is the appropriate venue for your question: https://www.dpreview.com/forums/1006

Not me, the last time I had to explain how to integrate flux over some bounded range of solid angle was about 30 years ago, so to spare myself the embarrassment: Take a look at. https://www.horiba. ...

For long extensions, you can often benefit by placing some light baffles ( as one would do in a refracting telescope ) to block stray light.   If you draw a napkin diagram of the exit pupil of the ...

Custom crafted from rich Corinthian resistors ?

The following is not directed at you, Detail Man, but rather to the equivalence zeitgeist: There is, obviously, an underlying physical reality.  Those with a scientific mindset can construct a formal ...

While we are just making stuff up, why not just come up with an international unit of equivalence, the "quivle" and we can have kiloquivles and microquivles and even very tiny picoquivles.
