100 times more sensitive to light than current ones. Imagine the ISO performance. You'd be able to shoot at like F* on a cloudy day in a forest!
Black silicon CMOS sensors?(16 posts) (7 voices)
Hi, I have known about this as I saw it when it was published... I think I have mentioned it in some other post either here or in the NR Blog. However, I have just reread it.. and the dates and seem to correlate.. Could it be possible that the D300 has Black silicon? Is that why the dust removal plate in front of the sensor is so dark The guy said that it is about 5-7 EV which makes it about 100 times more sensitive which matches the black silicon performance.
Have we stumbled on something here? Darn I am going to have to get me a D300 and remove that plate and see for myself!!
I doubt that d300 has black silikon, this material is newer than d300. Also if this was right, then we would hear abiut this some time ago, as for sure there was some people among us who removed the filter.
Putting on my physicist hat to clear up some misconceptions.
Black Silicon is not newer than the D300, it is in fact older than the entire line of Nikon DSLRs. It was discovered in the 80's.
Black Silicon is not called so because it is black or blacker than standard silicon, it is called so because it is able to absorb more light (like a black object) than a standard silicon based device thus not reflecting light as a white object would.
High ISO is no cure for poor lighting.
SiOnyx, the company holding the license on this technology, was the first and so far the only company that is trying to commercialize black silicon technology and was founded in 2006. Currently they are just trying to sell know how to the sensor array maker companies.
But it seams we are looking at a future here.
It seems stupid.
But has anyone ever stopped to think about the REAL implications of this?
1) It will be VERY expensive.
2) How the hell will you take pictures in broad daylight? You would need a ton of neutral density filters stacked together to get anywhere around acceptable results, and dont even think about doing shallow DoF work.
Really guys, get real on this one. For now there are a lot of ways to take pics in low light...
@ nemezote : So maybe that's why there is that 6ev Neutral density anti shake filter?
heartyfisher - is it really 6ev? I've read somewhere that it's something between 1-2ev
Again, get real.
What makes you think a measly 6 ev are going to help? We are talking a 100 (hundred times) more sensitivity here, possibly even more by the time it gets released. You know how much is that right? Because it seems you dont.
That 6 EV filter would only take away 6 steps of the new 100. Hardly enough. And dont think about stacking them, unless you like heavy vigneting of course. Unless there is a way to take that sensitivity back to normal working levels without any ill effects then this will just be a luxury/specialty/worhless item.
@nemezote : one EV = double the sensitivity.. 2 EV = 4, 3 = 8 , 4 = 16, 5 = 32, 6=64 seems pretty close to 100 times i think. Please be polite. Look, I know as much as those 2 articles.. The facts point to this possibility.
@adamz : the guy on flickr said its about 5-7 EV check the link.
Apparently you are not understanding it right.
If the article says "a 100 times more sensible to light" it means its 100 "EVs" more sensitive to light.
Not in the way you expressed. Thus, as I said, a 6 EV filter will only take away 6 of those 100.
You can think in "Steps" if that helps. This black sillicon will make a scene that needs, say... I dont know, an hour to expose in regular sillicon only take around...oh crap...I dont even want to calculate that...I just hope it doesent exeed 1/8000 at f/11.
PS: Black sillicon is NOT present on the D300 nor any other camera at the time,at least not that I know of. It would be interesting to see wich manufacturer gets interested by it first.
@ nemezote : from the article "Apparently light sensors using black silicon are 100 times more sensitive to visible light than conventional silicon sensors, allowing a pixel 1-micrometer in size to produce the same signal as a traditional pixel 10-micrometer in size" Note the diameter is 1/10 therefore they are talking about the area being 100 times larger. If you have an F2 lens have a look at the aperture size and compare it with an F16 aperture size(6ev diff) It should be about 1/8 the diameter. ( see the light? .. Jesus is Lord :-) sorry .. hope I didn't offend anyone.. lol .. Its late here and we have just had our church conference this week LOL)
I agree that it is unlikely that black silicone is in the D300 but how can we explain the 6 ev anti shake filter? to paraphrase old Sherlock Holmes "... whatever remains, however improbable, must be the truth."
Heartyfischer, for what it's worth, with what I remember from my scinece background and my 40+ years of photography, you're right. If someone said that something is 100 times more sensative, and they meant they were measuring using EV steps - I think I woulda heard about that sensor from my friends at the remote sensing lab.
Black silicon 100 times higher sensitivity means that for something we had to expose at f/4 for 1/250s we can now do with f/16 for 1/1500s for the same EV, and that is not so unreal.
And this is only true if we use pixels elements of the same size. If we make pixel elements smaller (that is actually desirable) and if we use some better color array than Bayer, we will actually be able to improve on the picture quality at much faster speeds.
All this is purely theoretical, and D300 of course does not have black silicon, the only thing you actually see when you open it is IR filter.
@mb: Oh well, so the flickr guy is just having us on? sigh..
You should not believe everything you read on internet. Doubt is what makes us human beings.
