Nikon Camera Control Pro “No camera was detected”

I’m posting this as question & answer because Google was no help at all for what turned out to be such a simple ‘fix’.

Connecting the camera to the computer showed it as being seen by the OS, but no amount of pushing or poking seemed to make Camera Control Pro 2 be able to detect it. The app would simply show the error “No camera was detected” & hang there. The only way out was to force quit.

This symptom survived reboots & also updating the app [in all I tried 3 different versions].

How do you make the Camera Control Pro application recognise your camera?

When estimating camera motion from the fundamental matrix, why can translation only be recovered up to scale using epipolar geometry?

I was wondering once you have recovered the fundamental matrix F such that xFx’ = 0. If you try to recover translation and rotation from F, I am told that this is possible only up to scale? Why so?

Why use DX format? It’s an FX camera

I covered “Nikon” and “D700” with black tape. Silly, I know, but it does seem to have a size and attention reducing effect.

The loud shutter sound. Well, it’s certainly not a quiet camera, but that has not prevented me from taking unnoticed shots in pubs and the like. I could imagine it being a problem in a theater for instance.

I use the D700 as a FF digital FE2 I guess.

Unity- Pixel Perfect Camera issue

So, I accidentally deleted the Unity Pixel Perfect Camera and can’t find any way to get it back; I have removed the Package from Unity and need it back for my game. I can kind of imported it from Git Hub but the code just broke because some assets were missing. I’ve probably spent an hour or so looking for a solution but found nothing. I’d really appreciate it if someone can help me!

Is there any way to record live input from my camera without any other hardware?

I have a Nikon Coolpix 510 and I was hoping to use a live feed from it without getting any more external hardware than the cable. Do you know of any way to do this? iMovie detects it and opens up its previously taken photos and videos but doesn’t allow live input like with the built in camera.

Is camera flash actually harmful to infants or newborns?

I just got a new off-camera flash, and the instruction manual says:

Never fire the flash unit closer than 1 meter from infants.

This was a little startling to me, since one of the main reasons I bought the flash was to take photos of my newborn son.

On the other hand, knowledgeable sources on the internet seem to say otherwise:

Q: Can a camera flash harm an infant’s eyes?

A: No, it cannot. Actually infants have more protection from a flash than adults since they are usually not interested in being photographed and do not look right at the camera. Also, they typically have smaller pupils. This means less light reaches the retinas. — Don Bienfang, M.D.

Q: Can a camera flash harm an infant’s vision?

A: The flash of a camera, even if used to take many, many pictures of your newest family member, should not harm an infant’s vision. Although the flash seems very bright, it actually isn’t much different from normal daylight. — Leann M. Lesperance, M.D., Ph.D.

So what’s going on here? Are the makers of the flash just avoiding a lawsuit? Is this a myth? Or are the doctors just thinking about little on-camera flashes and neglecting to think about more powerful flashes?

(And if it’s NOT a myth, can I assume that bounce flash is acceptable?)

Camera brands build quality ranking

In the age of cheap plastics and planned obsolescence, I find it a bit scary to go out there and spend a few thousand bucks on a camera whilst not knowing how long it’s gonna last me. I bet I’m the only one who feels this way.

From what I’ve heard and read, Canon and Nikon would be at the bottom of the list, whilst Leica and Pentax would be at the top. For the other brands (Olympus, Fuji, Panasonic, Sony, etc.), I’ve found it more difficult to figure it out.

How would you rank camera brands/makes in terms of build quality, robustness and durability?

Is there an adapter to allow a camera to control focus or aperture of a manual focus & aperture lens?

I recently bought the Sony Alpha a7. In a bid to get an affordable portrait lens, I rushed to get the Rokinon 85mm f/1.4 only to realize that there is no communication between the camera and lens. Now that I now understand how a manual lens works, I was wondering if there is any adapter of some sort that can help with either controlling the aperture or focus from the camera, or even both?
