that... And I connected those two words together on purpose, that the company has to find that really narrow path, step by step by step, to expand our aperture of computing, but not give up on the most important specialization that we had. Okay, so the first step that we took beyond acceleration was, we invented a programmable pixel shader.
What are the parameters of depth of field? Aperture, do we agree? Focal length. Distance from a subject.
Nothing about the journey of light down this barrel is a straight line. Apertures that I shoot at, I shoot wide open, I do portrait at 5.6, and I do landscape at F8 or F11, depending on where
- Yeah, it turned out to have been a good decision. I think the... So, here's the way it went. So, we invented this thing called CUDA, and It expanded the aperture of applications that, that we can accelerate with our accelerator. The question is, how do we, how do we attract developers to CUDA?
These cameras are mostly the same as last year, but I think that actually undersells how good they are. There's a bigger aperture on the main camera, the 3X is about the same, and then a bigger aperture on the 5X as well. So both of these cameras let more light in and get all the benefits that come with that, including slightly softer bokeh with close-up subjects.
And then pretty much all the rest of the hardware changes are just on the Ultra, which now has... slightly wider apertures on those otherwise unchanged primary and telephoto cameras just to let more light in. So looks like we're going from f/1.7 to 1.4 on the main and f/3.4 to 2.4 on the 3X.
Nothing about the journey of light down this barrel is a straight line. the critical aperture, which is where the light's most evenly distributed across the lens system, is.
Nothing about the journey of light down this barrel is a straight line. I put this on aperture priority, and I have a focusing system that , OK?
I shoot all my pictures, except my flash pictures -- as you'll see in the studio later when we move over there with Cliff -- I shoot either on the aperture priority mode or the shutter priority mode. A lot of my professional photographer friends shoot on the aperture priority mode or the shutter priority mode.
important thing. So why not shoot on the aperture priority mode? Set your aperture and then as the light level changes, the camera will automatically pick the correct shutter speed for the existing situation. Yes? Male #1: What metering mode do you use?
And a kind of city of these soft-like cars moving around. And we have over, or I did at least over 40-something variations. Here, in those soft shells with air quilt technology, you can have an aperture that traces the drivers viewpoint, creating a kind of hole, or the entire car could be naked and you can have a visor that tracks the sun, in this case. Or here, you can add just a simple armature to these wheels and the car can go vertically, or spin on a dime. So, now we're designing cars to fit cities, not the 20th century designed
shot, if I'm shooting a landscape, I'm using one of the automatic modes, believe it or not. A lot of my friends do this. If it's a landscape, a cityscape, a seascape; I'm shooting on the aperture priority mode. I can fine tune the exposure with a plus and minus control and get to the same place you can get to on the manual mode, only faster. If I'm shooting action, like those Mongolian horse riders, I'm gonna shoot on the time value mode or the shutter priority mode because I wanna freeze the action. If you're just
There was this wild game. It's too heavy to have that aperture open all the days long for our whole lives.
And in an instant, that was diffused. And so it really opened up the aperture of what was possible.
There are ways to address this, or there were ways to addressing this when I took the photo, but I didn't do that. Actually need to close down your aperture, and then you get the deeper depth of field. But I didn't do that unfortunately.
And I took my camera with me. I have a book by Aperture, two by 21st Editions.
And pre-focused at about two meters so that I don't even have to go to focus. And I'm always shooting in aperture priority. So in that case, I don't even have to put the camera to my eye really.
Anyway, this was taken with the 100 to 400-millimeter zoom and the background was very distracting so I'm shooting at a wide aperture. I'm shooting at a wide aperture to blur the background. In wildlife photography and in people photography, I do the same thing when I find a subject.
If you think about it, there's only one right exposure; right? And if you use manual or aperture priority, or shutter priority, it doesn't matter. I found since I've been shooting a long time that I can just use the exposure compensation wheel on my camera to dial in the right exposure very
right working in secrecy is it can be very very alienating this imagine having that was using something called a synthetic aperture radar bounce radar waves off the surface and get an image back using synthetic aperture radar you
- The smaller you make the features, the larger this angle, alpha, between the zero and first orders becomes, so the larger your lens needs to be to capture the light. The size of the lens is described by the numerical aperture or NA for short, which is just the sin of this angle. So the larger that is, the smaller the features you can print.
even okay? Can we talk about this?" Because if you talk about this, and you tell people there's these uncontacted tribes, people have misconceptions. across the beach was surreal because it's like this aperture into history.
And in an instant, that was diffused. And so I've really been able to open up the aperture of what that word means for me, not just so much in the usage of that word, but more in my expression
So the takeaway message is that we need to widen our aperture.
So it measured dust by the impacts onto the aperture.
shoot either on the aperture priority mode or the shutter priority mode. A lot of my professional photographer friends shoot on the aperture priority mode or the shutter priority mode. If you think about it, there's only one right exposure; right?
the point is, if you set goals, if you wanna do a beautiful landscape, some of the things that help with landscape photography is tremendous depth of field. So you would wanna use a wide angle lens, a small aperture and set the focus--this is gonna sound backwards-- set the focus one-third into the scene. Lock the focus one-third into the scene. So to get a tremendous depth of field, again, wide angle lens, small aperture and focus one-third into the scene. You also wanna get up early in the morning and stay out late at night. Another one of my photography
All of this is captured by the Rayleigh Equation, which determines the smallest feature size or critical dimension. - But since there's a limit to how much you can increase the numerical aperture, I mean to one, over time, the only way to keep making smaller and smaller features is by using shorter and shorter wavelengths.
This thing here is actually a thing that you flip over to cover the aperture, and the reason that Doc Ewan put that there is that he
That's how I keep the detail in the sky is the aperture and the metering option.
No. Focal length has nothing to do with it. Distance of the subject does, aperture does, and something called angle of view. All lenses have the same depth of field.
And they are essentially eliminating or not seeing this other set of apertures.
quickly. And in a case like this, a case like this, a case like this, case like this, the depth of field is the most important thing. So why not shoot on the aperture priority mode? Set your aperture and then as the light level changes, the camera will automatically pick the correct shutter speed for the existing situation.
So the larger that is, the smaller the features you can print. But there is a hard limit to how large your lens system can be when this angle is 90 degrees and your numerical aperture is one, where your lens would have to be infinite.
knows somebody, and so how could we expand the aperture of what this looks like?
200-megapixel main camera with the biggest 200-megapixel sensor we've ever seen in a phone with a wide aperture and OIS.
The missions that were talked about at the time and that are continuing to be talked about are these large aperture space telescopes.
And as we think about those challenges, boardrooms basically decided they needed to widen the aperture of who should sit on the board
And then, only because other publications, like "Aperture" or "British Journal of Photography," these are magazines which are on the market from 100 years.
an electromagnetic field. And certainly one of the concepts they're looking at for wide aperture type telescopes, where
So back in the old days, they had what's called an aperture card, which is an IBM punch card with a piece of microfilm in it.
I mean, there are people who can have very serious conversations about lighting and scrims and aperture.
And so, you want to shoot at something like F 8 or big wide aperture.
I just have to get off this ship so I'm taking some snapshots just walking around the ship. So play around with shutter speeds, play around with aperture.
the four levels of learning. We only have three on the screen. So the first level is the unconscious incompetence. We don't know we're not that good. We get a little digital camera, we play around in Photoshop or Lightroom or Aperture or wherever and we're having a lot of fun. We don't know we're not that good, right? Then, we start to look at other people's pictures, right? And this is the second stage, the conscious incompetence. We know we need help. So my guess is that's why some of you came to the-- actually, there's a lot of smiles
image stabilization lens set at 400, or I could of taken with a 70 to 200, set at 200, but the picture wouldn't have the same sense of intimacy as that picture or this is. I'm pretty close to this subject. I'm shooting at a wide aperture to blur the background. Once again, the background can make or break the picture. Here, there are a lot of twigs and everything in the background and leaves, so I blurred them to draw attention to the
And maybe that's why it's a challenge, right? Because as the aperture gets wider and you interact with more and
the application and more about here's a tool, skill set, or kind of awareness aperture that you might be able to use beyond.
offer options, they're like, "How do I know it isn't just gonna be like this other thing?" So we have to also have a very broad aperture and say,
As humans like to, I think, have an inherent desire to learn, to be curious, to want to expand the aperture
