Depth of field - two of them?

"Commander Kinsey" wrote in news https://www.dropbox.com/s/ctqungbvve...field.jpg?dl=0 This is a snapshot of Startrek The Next Generation, Season 6, Episode 26. It appears to have two planes of focus, one centred on the right eye of the man in the foreground, and one on the right side of the chest of the man in the background. Two cameras with superimposing? Or some effect put in afterwards? Going by the still and not seeing the video I would assume the Borg is a chromakeyed background since the lighting is quite different on them. Are you sure? What makes you say the lighting is different? |

Resistance is futile. :-) Well to some extent anyway. I doubt they can manipulate the focussing of themselves. |

It's used more often that you might think, and you'll find examples of both tilt (tipping the lens up or down) and swing (turning it left or right) as with the train or ST:TNG still if you know what to look for. Tilt is often used for purely creative effects or extreme depth of field for long-distance shots, swing is mostly used for keeping two characters (or whatever) in sharp focus like this is really the only usage I've noticed for swing. Swing is a pretty good solution for scenarios where the director wants a deep depth of field but lighting conditions mean high ISOs and/or wide apertures. The limiting factor is more the camera used and what mount options are available as realistically, you need Canon EF or Nikon F mount, although there are a few other options for TS-E/PC lenses. Now that DSLR lenses are being used more for broadcast video the options for tilt/shift lenses have gone up and I expect to see much more usage. In the days of plate and cut-film cameras, most such cameras had the ability to employ a number of such adjustments. Only the more expensive 'technical' cameras offered the full range.

I don't know if the video would show them interacting in a way that showed they were being filmed at the same time. |

But there are several lights in the room. Like I said this is just from the still. I don't know if the video would show them interacting in a way that showed they were being filmed at the same time. They were interacting. Whether they were filmed simultaneously I can't tell. |

Not particularly good, or am I missing something? Yup, you are missing something. That is 75-micron pixel size, not 75MP. However, the actual photo resolution is 12 MP @ 3888 x 3072, and it is B&W only, and you will get images that only a large area sensor can produce. ....and it only costs $106,000 without a lens. http://largesense.com/gallery/ http://largesense.com/products/8x10-large-format-digital-back-ls911/ https://youtu.be/CgpioaDb3Fs -- Regards, Savageduck |
