New Camera Sensor

Recommended Posts

Given that they've already got it in a prototype I expect to see it in high-end cameras this year - I can't see Canon sitting on technology like this for very long.

How long after that it takes to reach point-and-shoots I don't know. I suspect that shift will be driven by how much this sensor drives people to DSLRs. I can see this pushing lots of people who are just starting to consider a DSLR to take the plunge. Myself included.

Larger photosites mean fewer photosites per area. If we assume the sites are the same shape, increasing their size by 7.5x will reduce the number of sites in the are by the same amount. (Where a sensor was 22.5 MPx, the new version would be 3 MPx.) That's fine for most video uses, since HD output is about 2 MPx. For stills? Not so much.

 

Then there's this:

 

"In addition, the sensor's pixels and readout circuitry employ new technologies that reduce noise, which tends to increase as pixel size increases."

 

While true, it's misleading. Noise does increase with photosite size, but signal to noise ratio tends to decrease (and rapidly, too). It's one of the big advantages of larger-sensor cameras.

 

Interesting for exactly the uses they talk about, but not very interesting for general-interest video or photography, IMO.

I am impressed with the low-light performance and it would seem to me that higher sensitivity even in normal light would permit much tighter apertures for video as well as higher framerate for high speed video.

As for when it will go consumer...I predict that time will be about 15 years before I can afford one.

Also, I am sure that at this very moment Nikon is developing a comparable sensor that will not only do what the Canon one can do, but also make coffee, sort and wash laundry and prevent tooth decay. Any Nikon users care to confirm? :D

I'll be upgrading my Nikon if the new sensor makes coffee and does my laundry in a heartbeat!

      Newly finished, WIP here:  https://forum.reapermini.com/index.php?/topic/87616-making-another-background-for-photographing-miniatures/
       
      This whole piece went faster and easier than the first.  This final step was using a very heavily watered Burnt Sienna (Apple Barrel) with (too much) dish soap.  I usually aim for a small drop or two, but this ended up with a squirt!  So using my sponge to apply, it actually sudded up pretty bad, but I was able to poke at the bubbles and blow them off the paper to get basically what I envisioned.  I'll call it a win!
       
      What I don't know is whether to call it.  Is it finished sandstone or yellowed parchment?  Suggestions on names?  Next theme?  Anything?  Enjoy!

      Finished this a while ago actually, but am just now posting the finished product.  I got a bug and am now making a few variations on these--just on art paper for the moment, but I wouldn't mind having them printed on neoprene or something a little more durable.  Now I just need more minis to photo in front of them!  Let me know what you think.  WIP here:  https://forum.reapermini.com/index.php?/topic/83003-attempting-to-paint-generic-backgrounds-for-miniature-photography/&tab=comments#comment-1760821

      I started this in a WIP and have finally finished my first background for taking pictures.  This one is made with fairly lightweight watercolor paper.  I taped it down tight, primed with gesso, and built up from light to dark layers (all cheap craft paints).  The concept was for the whole thing to appear nebulous, as a dark cloud with obscured lighter flashes.  I think it turned out pretty close to my vision.  The half-painted creatures are just my first test shot with the background.  My phone camera did occasionally try to focus on the background, so on the next attempt (some kind of brighter theme) I will try to soften the edges (paint started to dapple on the blacks and grays).  What do you think?

      For those curious, the bug is primed in Reaper brush on primer, black, and it's carapace has two coats of Golden's Interference (purple-green) paint.  Boxy is clean Bones, primed with Brown Liner with Old West Rose fleshy bits.  They'll get their own WIP soon.

      I recall reading an excellent tutorial a long time ago regarding how best to shoot one's finished minis, but I've been unable to find it.  I largely suck at it.  I'd like to acquire a background against which to shoot, and I don't know from where I could purchase one.  I need to know what kind of lighting is best.  I think I read that you need at least two light sources, and I wondered if a certain kind of bulb was best.  If anybody has the link to that tutorial, I'd like to go over it.  Thanks.

      NSFW link: https://www.theguardian.com/artanddesign/2016/jul/09/thousands-strip-naked-in-hull-for-spencer-tunick-photographs
       
      3200 British volunteers took off their clothes and were painted four shades of blue and photographed in the streets of Hull as part of an art project by American photographer Spencer Tunick.
       
      Tunick specializes in large photographs of crowds of nude people. The blue color is symbolic of Hull's relationship to the river and the sea.
       
      I was amazed at the cheerful volunteerism exhibited -- the models are unpaid -- and the sheer variety of people participating. It seems to me an eye-opening sample of what regular people look like naked (well, partly, since in this project each person is painted monochrome).
