Kodak Capture Pro Serial 252
To report a not yet supported camera to the gphoto development team follow the instructions below:If it a USB mass storage based camera (appearing like a USB stick or USB drive) it is mounted by your operating system and not gphoto2. In this case a report to us is not necessary.Record the output of lsusb to get the USB ids.Record the output of gphoto2 --auto-detect to see if it is detected in a generic way, or by another name. If it is detected already, run the steps below:Record the output of LANG=C gphoto2 --summary >summary.txt to get generic summary information into the summary.txt file.Record the output of LANG=C gphoto2 --list-all-config >config.txt to get the configuration tree into the config.txt file.Record the output of gphoto2 --capture-image to see if capture works already.Mail the output results with the camera name to gphoto-devel@lists.sourceforge.net.
Most U.S. kinescope situations, however, utilized a mechanical shutter, revolving at 24 revolutions per second. This shutter had a closed angle of 72 and an open angle of 288, yielding the necessary closed time of 1/120 of a second and open time 1/30 of a second. Using this shutter, in 1 second of video (60 fields equaling 30 frames), 48 television fields (totalling to 24 frames of video) would be captured on 24 frames of film, and 12 additional fields would be omitted as the shutter closed and the film advanced.
A development on the suppressed field system was to display the image from one of the fields at a much higher intensity on the television screen during the time when the film gate was closed, and then capture the image as the second field was being displayed. By adjusting the intensity of the first field, it was possible to arrange it so that the luminosity of the phosphor had decayed to exactly match that of the second field, so that the two appeared to be at the same level and the film camera captured both. This method came to be preferred.
Because each field is sequential in time to the next, a kinescope film frame that captured two interlaced fields at once often showed a ghostly fringe around the edges of moving objects, an artifact not as visible when watching television directly at 50 or 60 fields per second.[33]
When the EOS 5Ds and 5Ds R were released, image quality factors relating to that high resolution were a primary concern.Magnify the image being captured and problems not visible before become apparent.While the 5D IV is not as high resolution as these models, it still has a very high resolution.
Canon suggested that the Dual Pixel RAW Optimizer would work best with wider apertures.Load the same 60mm image captured at f/8 and the ability to positively affect Back/Front changes practically disappears, though the softening effects remain.The light received by each half of the pixels is apparently not dissimilar enough to allow for adjustments.With an f/5.6 image, only very slight adjustments can be made and at f/4, you might find making adjustments to be worthwhile.
With a near-infinite number of subject/scene, lens and aperture combinations available to feed the DPRO tool, it is impossible to test all possible scenarios.But, I want to share a selection of adjustment results on a sample image captured at 60mm f/2.8.Images were processed using the Standard Picture Style and, unless otherwise specified, a Sharpness setting of "1" was used.
Note that, with twice the information being captured with DPRAW enabled, file sizes increase by a factor of 2, the high speed burst buffer capacity is significantly reduced and the high speed burst rate is impacted.
What Canon has not talked about is the potential for increased dynamic range being available from Dual Pixel RAW files.It seems that, if partial exposures are being captured by the Dual Pixel RAW system, the potential exists for very significant highlight recovery beyond what is already available.
I shoot in RAW format nearly 100% of the time, but for those that do not, having lens corrections available in-camera is a very positive benefit.Lens corrections available in the 5D Mark IV during image capture are peripheral illumination, chromatic aberration, distortion and diffraction along with DLO (Digital Lens Optimizer).The latter has only been available in DPP (or in-camera during RAW processing) since this camera model introduction.Note that DLO enabled will slow down processing.
When the stadium lights come on, you can expect to be reaching for very high ISO settings to stop action with an f/4 max aperture 600mm lens.The image below was captured at ISO 10000.While you cannot make out individual eyelashes in the full resolution image, noise reduction can make the image very usable at even moderately large sizes.
Also note that the in-camera-captured JPG images utilized the default Standard Picture Style.Maybe someone can set me straight, but I don't understand the oversharpening decision (look for thehalos in this comparisonwith the sharpness set down to "1").Perhaps this sharpening level makes a low-grade lens look better?There is definitely damage being done to image details in these results.However, this sharpness level appears more appropriate for high ISO images.
Also provided in the noise tool are many "Exposed * EV" result sets for the 5D IV.These images were intentionally over or underexposed at capture and adjusted to the standard brightness during post processing.These results would be similar to getting the exposure wrong during capture, increasing brightness of shadow detail or recovering highlight details.
The 5D IV's frame rate was increased from the III, but the RAW buffer capacity did not receive as significant of an upgrade.If photographing action, the start of the ideal 3 seconds needs to be determined for the initial shutter release press.For a solid percentage of subjects, three seconds of capture is adequate and the 7 fps rate is a more valuable spec to me than the RAW buffer capacity.Of course, the 5D IV will capture JPG format images at rated speed until the card is filled (assuming an adequately fast card is used).
Reducing any concerns about the buffer depth:using a Lexar 64GB Professional 1066x UDMA 7 Compact Flash Card(Max. Read/Write Speed: 160/155 MB/s), the 5D Mark IV captured 36 frames in 4.98 seconds to precisely match the rated speed and far exceed the rated buffer depth.In addition, with this Lexar card installed, additional frames continued to be captured at a 4.4 fps rate.If DPRAW capture is enabled, the frame rate using the same card drops to 4.9 and the buffer wall is hit at 9 frames.Subsequent frames are captured at a 2.2 fps rate.The larger-sized DPRAW images definitely impact performance in this regard.Smaller file sizes of course positively influence the buffer capacity.With mRAW selected, the 5D IV was able to capture about 43 frames until a very slight pause began to show after approximately every 4 frames, resulting in slightly less than 7 fps after the initial 43.
Using a Lexar 128GB Professional 1000x UHS-II SDXC U3 Memory Card,the 5D Mark IV captured 21 frames in 2.85 seconds to once again match the rated drive speed and also match the UDMA 7 buffer depth rating.Using this card, the post buffer-filled frame rate was 1.6 fps.
Using a Sony 32GB Class 10 UHS-I (SF32UX) SDHC Card (Max. Read/Write Speed: 94/45 MB/s),the 5D IV captured a respectable 24 frames in 3.28 seconds to again precisely match the rated drive speed and exceed the rated buffer depth by a few frames.Using this card, the post buffer-filled frame rate was 1.6 fps.So, the slower UHS-I card recorded a higher number of frames before filling the buffer than the faster UHS-II (not-supported) card.However, this card could only handle 6 seconds or less of 4k video recording.
A properly AF-calibrated camera/lens combination is a requirement for accurate autofocus and as already discussed, the 5D IV has the ability to fine tune AF calibration.Up to 40 lenses can be specially calibration-adjusted to the 5D Mark IV with automatic (or optionally, manual) detection of the serial number of the mounted lens and multiple copies of the same lens can be differentiated.This latter feature is not going to mean much to most individuals, but it can mean a lot to agencies, schools, rental houses and other organizations that have a large pool of cameras and lenses available.Separate AF Microadjustment settings are available for both the wide angle and the telephoto focal lengths of zoom lenses.
In the few weeks I've had the 5D Mark IV in my hands, I've captured nearly 10,000 images in AI servo mode.Subject have included runners, soccer players and wildlife (elk, mule deer, pronghorn, bison, moose and more).Lighting conditions have included bright mid-day sun (when heat wave distortion has been problematic), intermittent cloud cover,heavy overcast skies, rain, snow and stadium lights at night.
New to the 5D-series is an HDR Movie feature available in when shooting at FHD 29.97/25.00p (.MOV or .MP4). With HDR Movie mode enabled, the camera reduces clipped highlights allowing for a higher dynamic range to be captured in scenes with high contrast.To accomplish this, the video is recorded at twice the selected frame rate using an alternating brightness that becomes blended for the final result.This feature works.It is easy to record the same high dynamic range scene with and without the HDR Movie feature enabled and see the highlights nicely retained with a natural appearance.
Of course, the biggest video feature upgrade in the 5D IV is the ability to record DCI 4K (17:9) video.The value of being able to record 4K video cannot be understated, even if your typical output is only Full HD 1080p. The additional resolution captured in 4K recording is substantial. The illustration below demonstrates the difference between Full HD and 4K resolutions. 2ff7e9595c
