Sorry Handruin, I didn't know about this place when you were out. A friend just showed it to me tonight. Sweet.
Why? Does PS even use 8GB in Windows?
Your shadows called. They miss you.Yup, I really need to work on queuing things for the night and then going to bed. I don't have the workflow sorted that well yet. And Photomatix choked on the 75MP image (even in "preview mode"). I'll look into working around that when I wake up.
Oh, I really like this one.
Or check it out full size.
Sure does. Stitching 32-bit Radiance images into a 76MP image burned through all 8GB and then started attacking my Raptors. It was undoubtedly disk-limited.
In the small image at least, it looks like something went rather wrong in the processing. (I don't have the bandwidth this morning to load the entire image.) Contrast is very low and there are no blacks. Did you overly apply shadows/highlights or some other tool that messes with the toe? Did you set black levels based on the junk in the foreground?
I'd be happy to access 8GB, but that requires CS4, a Mac or Vista, no?
CS3 is a 32-bit application. How can it address that RAM?
Sorry Handruin, I didn't know about this place when you were out. A friend just showed it to me tonight. Sweet.
Q. It's clear that EOS-1D Mark III and EOS-1Ds Mark III autofocus isn't meeting your expectations. Why are you still shooting with these cameras?
Quality and Cropability The EOS-1D Mark III produces the best overall file of any digital SLR we've ever used. A CR2 coming from this camera contains a level of detail, dynamic range, tonality and quality from each of its 10.01 million image pixels that is hard for any other camera to match on a per-pixel basis. The Nikon D3, for example, produces a better NEF at really high ISO settings (plus very good quality generally), but at lower ISOs it can't quite deliver the fineness of detail from each pixel that the EOS-1D Mark III does.
As a result, the EOS-1D Mark III delivers impressive printed enlargements for a sensor of this resolution, and great cropability too. Click on the thumbnail at right to see an example of how you can pull out a usable photo from this ISO 800 file. The enlarged view is only about 1/6 of the frame. Canon has made the most of every image pixel in this camera.
Both of Canon's current 1-series models now deliver acceptably stable and accurate autofocus of subjects that are stationary or whose distance to the camera is changing fairly slowly. With the lenses we own, from wide angle to supertelephoto, we have no significant complaints about the EOS-1D Mark III with firmware v1.2.3 and EOS-1Ds Mark III with firmware v1.1.2 when photographing things that are static or moving slowly. Are these camera reliable for shooting things that mostly hold still? In our experience, yes.
No, I meant that every lens for the mount had to be a telecentric design. Not even extreme wide angles were excepted.I didn't even know what telecentric meant before. When you say 100% telecentric, do you mean double telecentric? That was really a requirement?
I also appreciate the Nikon D700's viewfinder blackout speed, which seems quite a bit faster than the Canon 5D's rather sluggish performance. The duration of shutter sound is also a lot shorter on the D700, attracting less attention than the 5D's long, slow mirror slap and winding sound.
- 15.1 megapixel CMOS sensor
- DIGIC 4
- AF Fine Tuning
- ISO 100-12800
- 920,000 points VGA 3.0-inch LCD monitor
Why not use ISO 100? Also, did you check the menu system for enabling long exposure noise reduction? I believe what it does is that the camera keeps the shutter closed but takes the information from the sensor for the same amount of time as the original exposure you shot. Then it subtracts the difference of the two.
Those leaked EOS D50 specs on Canon's Chinese site? Real.
The camera can capture video and includes a speaker for sound output during video playback.
Who's going to buy a 40D now, if the 50D is only $300 more? Not enough differentation btw a Rebel 450D and 50D to make the 40D viable now, IMHO. Sales of the 40D will tank.The Canon EOS 50D digital SLR will cost $1,399 body-only when it ships this October. A kit version including a 28 - 135mm zoom lens will also be available, priced at $1,599. The Canon 50D will accept virtually all EOS 40D accessories, including the battery grip, remote control, optional focusing screens, and battery. The existing Canon 40D model will remain in the line through the end of 2008, with a price drop to $1099 body-only.

This was overheard from Canon staff...
"The 50D sensor and image processing are a major step forward in what has been a multi-year strategy for Canon to take sensor technology to the limits of physics, simultaneously achieving higher ISOs, lower noise and higher dynamic range. Note Chuck Westall’s announcement that the 50D sensor has 1 to 1 and a half stops better noise than the 40D sensor despite the smaller pixels. Several core strategies have been pursued simultaneously for this:
* Reducing the micro lens gap to capture all the light hitting the sensor. This has been highlighted in the 40D, 1D III and 1Ds III sensors and the new 50D sensor now achieves effective 100% coverage. Only very minor improvements are expected from this point on (e.g. shaping the lenses towards the corners of the frame to capture angled light.
* Reducing the noise level of each pixel. Canon have made changes over several generations of sensors to achieve this, bringing the amplifiers closer to each pixel, changing micro-circuit configuration and lowering voltages so the sensor runs colder. Again the design of the 50D is a big step forward here from the 40D and 1D III etc. Canon have one more big jump lined up, with low voltage cold running CMOS designs to gain at least an additional stop in lower noise at higher ISOs or long exposures.
* Better digital noise reduction. These are the changes in DIGIC noise processing. First with the Chroma Noise reduction in DIGIC III and now with more advanced multi-level noise reduction options in DIGIC IV. Canon believe they have made most of the gains possible via processing algorithms but do still have some areas to develop. The next focus will be faster noise reduction processing so that it does not come at an impact on frame burst rates (look to the 1D3 replacement for example)
* Pixel binning for high ISOs. A new technology enabled by the complexity and processing power of DIGIC IV where they can bin 2, 4 or 8 pixels together at the raw level and average out the noise between them. This is seen by Canon as a key technology in balancing very high resolution sensors (in the 50mp range) with low noise at very high ISOs. Right now they are not pushing this too much with the 50D so as to not create confusion in the market (they see more potential for the technology as sensors get larger and in the pro-market).
* Increased image resolution – This is a newer strategy (most evident on the 450D where they have changed the anti-aliasing filter (thinner and closer etc) so as to achieve a crisper image per pixel without loosing the benefits of anti-aliasing filter on diagonal edges etc.. The 50D has the same technology. One further option for the future is for Canon to drop the anti aliasing physical filter and do it in a future DIGIC generation where there can be smarter allocation of colour values than the blurring achieved by a light based filter.
* Increased raw bit depth for improved dynamic range. Here Canon have made the jump to 14 bit and will move to 16 bit in their future sensor technology generations. Canon see the main usage of extra bit depth as providing the dynamic range to translate the sensor image into a printable or viewable image with a higher dynamic range. In other words mapping the 14 or 16 bits into an 8 bit viewable or printable image that mimics the dynamic range in the scene.
* Dynamic range preservation options – Canon are putting a lot of focus into how to provide the photographer with the best options for preserving the dynamic range of the original image in both a RAW file and the 8 bit JPEG. The highlight tone preservation option on the 40D, 1D III etc was the first step. The new 'automatic brightness' options in the 50D are another, where they try and optimise the brightness of various parts of the image to reduce the dullness from shadows. Canon are planning much more in this area, down to the equivalent of varying the ISO level across the different parts of the sensor when the image is taken (easier in live view mode of course).
However the official party line (at least in Hong Kong) is to say:
- "We have just annouced a 50D, which is the 40D's sucessor, we have one more SLR coming this year, which is being highly anticipated but not yet as high grade as 1D series, please stay tuned for further annoucement "
