Dragon and Sony F55 – Resolution, pt 2

This is pt 2 of the resolution comparison between Sony F55 and The RED Dragon, based on the files from the CML/UWE cameratest. Part 1 can be found here.   So here are the UHD results. Dragon scaled down to UHD, F55 cropped down to UHD (Click on the image to get a low-compression fullrez .jpg)     And here is a 100 pixel center-crop comparison from the above images.     And finally: A downloadable uncompressed TIFF of the above comparison.   As far as I can see, there…

Dragon and Sony F55 – resolution pt 1

Adding the F55 to the soup after the Alexa/Dragon comparison. As with the previous post, the files are sourced from the CML/BSC/Geoff Boyle Bristol/UWE gathering in February. Shot 4k raw, developed to 16-bit log-dpx with Sonys RAW viewer. Initial comparison, both un-cropped. Dragon on top. (Click on image to get a fullres jpg)     I’d say that the FOV of these is sufficient to just crop the Dragon into 16:9 and make the UHD/1080 comparisons from there. here both cameras are cropped to 16:9     Here are the…

Dragon and Alexa – Looking at resolution – Part 4: Resolution, does it matter?

(6k low-compression .jpg pops up if you click the image) To me, an image can technically be broken down to these aspects: Dynamic range Color cleanness Color fidelity/Saturation Resolution Delivery formatAnd as a final parameter: Is the camera available? (!) All these aspects of an image/camera are part of the matrix that makes us choose one over another for a particular production. After these (to me) these more emotional points come in: Ease of use on set If it works well for the shot I want to get Price of…

Dragon and Alexa – Looking at resolution – Part 3: The scaled-images

UHD Here is the UHD scale for Alexa and RED Dragon (click on the images and zoom in to get a 1:1, low compression .jpg): The 770 pixels untouched center-crop:   The center-crop with unsharp mask applied:   And finally a link to an uncompressed TIFF of the log center-crop.   1080 Fullrez 1080 scaled:     The 770 pixels log center-crop:   And the centercrop at 1080 scaled with unsharp mask applied: And finally the unsharp mask TIFF So far I have avoided commenting the results, but this final…

Dragon and Alexa – Looking at resolution – Part 2: The base-images

Here are the basic frames I start off with (You will find the RAW files on the bottom of this page) Dragon was shot at full resolution, (6144×3160) pixels. Alexa was  shot at full resolution: (2880×1620) pixels The following image illustrates the difference in captured pixels (Click image to get a 1:1 pixel representation):   The FOV of these two images is not equal, which made Geoff decide against publishing. I was curious if I still would have a “relevant” frame for comparison if I cropped the Dragon image tomatch…

Dragon and Alexa – Looking at resolution – Part 1: Preface

Back in early February 2014, I took part in Geoff Boyles UWE/CML camera-test. Video for rent here: https://vimeo.com/ondemand/cameras Geoffs extensive analysis here: http://www.cinematography.net/UWE/index.html Geoff put a lot of work into that material, and what little I will be doing here is complementary, not in concurrence with his work and findings. In addition to what is published, we shot some resolution tests, which Geoff decided not to publish, as the framings were uneven, and I did a couple of tests on my own. I will mainly be focusing on Dragon and…

Epic and Dragon comparison – Part 1, Overexposure

This post might become lengthy… And the images come from Dragons original OLPF. But as this is what is currently the mostly available config (and the cameras I rent), it is still a slightly relevant comparison. I will come with some analysis on Dragon and a few other cameras, as time allows, but this is the most “Ready” images I have at the moment. I will NOT take it through every stop imaginable. Instead I will focus on the parts that mostly interest me, and break down the things I…

Dragon scores highest ever on the DxO camera-reference mark

RED Dragon does rather well in this test. Interesting read. This is a comparison of Dragon with most still-cameras out there, including Phase ONE and Nikon D800 A motion-camera outperforming the best of the stills-only camera for stills, is kinda a 1st ever. What they write about saturation in the full exposure-range and general fidelity, sounds a lot like what I have seen since I first tested the prototype back in August 2013, doing “Sweet”. Rent Dragon from me…

ADD – Take 2: Splitimage – 6400 ISO – Tungsten

This is an image from the “Espen” Epic and Dragon comparison. (yup, I will have that up here, too…)   6400 ISO To the left Developed with ADD Right – Regular developing First a 1:1 pixel center-crop at 1080 (click on image to get full-size)   Look at the nuances in the shirt and the details in his hair. Next a 2k scaled image from the 6k Source (again:click on the image to get full-size)     If you like me to publish tests and have use of what I…
