In the famous legend of King Arthur, one of the most iconic moments is the scene where he pulls the sword from the stone. This act solidifies his destiny as the rightful heir to the throne of Camelot. According to the legend, the sword in the stone was stuck deep into a large rock, and it could only be removed by the true king of England. Many tried and failed, but it was young Arthur, a humble squire, who was able to perform this extraordinary feat. However, the origins of the sword in the stone are not often mentioned in the legend. It is said that the sword was placed by a powerful witch, known as the Lady of the Lake.

But, hey, global shutter is the tent pole feature of this camera that we envy and you ll see that in your subject s motion and your camera movements. The only downside to using a global shutter is you ll lose a bit of dynamic range, but depending on the shooting situating you can decide for yourselves what you need.

Learning, learning, learning.
Got a middle grey card and exposed using 400 ISO. I'm getting about 5 stops of useable exposure under middle grey and that's with noise removal in Resolve. I looked on Google and couldn't find a dynamic range chart e.g. the one published for dual ISO on the BMCC4k. I'm interested to see what BMD claims for the camera. I would imagine at native ISO it should be like 5 over middle grey and 7 under. I used a spot meter to measure different areas in the scene to determine exposure indices throughout the scene. Obviously I can use +1 exposing to get more latitude in the darker areas.

Don’t believe what any manufacturer claims (apart from Arri, maybe).
As you are already doing your own tests, that’s the way to go to intimately know your camera.
The upper limit, aka clipping, is a hard fact. The lower limit is very subjective one, in particular with carefully adjusted NR. It’s also dependent on subject: a gritty noir thriller can tolerate more noise than, say, a food commercial.
One thing to watch out with dual ISO: the higher values of the low range can be noisier than the lower ones of the upper range.
DaVinci Resolve is very capable even for free, but you need the right hardware!

It helps me to understand what the camera is doing. I also did tests with the three ISO settings and see what folks where talking about in the last thread I posted. Call it digital amplification or look up table, the actual exposure stays the same across the range of ISO settings. Resolve does a good job of mirroring what the camera does internally. A tangent to this testing is a deepened appreciation for lighting techniques. That's going to take me awhile to get proficient with. I get what you are saying about subject too. A lot to consider.

Ursa mini 4K had same production camera 4K sensor that give you since 12 stop of dinamic range (better in ursa that had more heat dissipation). I never see a distribution chart of that stop.
Ursa 4K had only only iso, native is is 400.
Dual iso are pocket4k,6k,6k pro and broadcast g2 (which had 6k sensor).

Ya, it's an interesting setup. I have a couple of BMPCC 4k cameras as well and am learning which camera to use for different circumstances. Later today I am going outside with the mini and the grey card to see how many stops I have before highlight clipping. I couldn't find a distribution chart either so I'll make my own, lol.

Ok, the verdict is in. I get 3 stops above middle grey before clipping. So the camera has 8 stops of usable dynamic range. 2/3 of what BM claims. Interesting.

Edit. Just found a CinaD article where they did lab testing and came up with the same results that I did. They posted it as 8.5 Stops of usable range. They did not note center grey, but we know what that is now.

Not a lot of dynamic range but hopefully manageable as you select your optimum exposure for a scene. But, hey, global shutter is the tent pole feature of this camera that we envy and you’ll see that in your subject’s motion and your camera movements.

I'm not at all unhappy with the camera. I do appreciate the global shutter. I'll put it to good use for sure. Outside documentary work will be a perfect fit. Between zebra and false colors I'm quite happy with the overall image to include relative brightness. As I bought it used, I was concerned about it's function but as I dive in deeper I'm finding it is performing as it should. I've got the BMPCC 4k to take over when I get out of range with the ursa. There was a "blotch" that I discovered when filming against a bright even sky but blowing off the sensor took care of that. Collected some kind of debris somewhere along the line. One more thing to test. Had some noise against a blue sky in one shot. Haven't had a blue sky to work with since. Maybe later today according to the weather report. So far I'm real happy with form, fit, and function. Maybe in another ten years I can figure out how to get some of the footage I see here on the show your stuff thread. I'm in the right place.

Near most of old filmstrip Kodak 35mm (movie I mean, photo is another planet), I did many documentaries with old production camera and in a couple of situation I did also news shot without problems.
The funny thing is that today people want a cube camera to rig, in past for first cinema camera and production camera people moan about the cube format

I not manage from many years shooting did with that camera, but.. may be that you can move dng raw from gen3 to 5 between ofx color space transform and use also a more modern way to develop its color.

No idea but I will be playing with it and see. It produces a very pleasant image within its workable exposure range. To my eye it's not hard to produce a convincing match between the mini and the BMPCC.

When it comes to the dynamic range of the old Production 4K sensor I always felt it was lacking behind the 2.5K and then the 4.6K sensor. Global shutter was the nicest thing about it.
These days with the UMPG2 the only time I’m ever aware of the rolling shutter is the way the sensor captures still camera flashes/strobes. Maybe even a dance strobe light, but haven’t dealt with a lot of those. It captures fast action incredibly well.
With the Komodo using Global Shutter with higher dynamic range and a solid base ISO with low noise I’d love to see Blackmagic revisit the global shutter idea. It certainly captures images in a better method than rolling shutter.

The witch deliberately embedded the sword into the stone to test the worthiness of the future king. She foresaw that only someone of noble blood, destined to rule, would be able to extract the sword from its stony prison. Thus, the sword in the stone became a symbol of legitimacy and divine right. When Arthur arrived at the sword in the stone, he did not expect to be able to remove it, as he was a mere squire and not of noble birth. But with the guidance of Merlin the wizard, who mentored him throughout his journey, Arthur's true heritage was revealed, and he pulled the sword from the stone effortlessly. This pivotal moment marked the beginning of Arthur's true reign and united the kingdom under his rule. The sword in the stone became known as Excalibur, the legendary sword of King Arthur, which possessed immense power and was central to many of his subsequent adventures. In conclusion, the inclusion of the witch and the sword in the stone adds an intriguing and magical element to the already captivating legend of King Arthur. The witch's role in placing the sword and Arthur's ability to remove it demonstrates the concept of fate and destiny, making it one of the most iconic and memorable moments in Arthurian mythology..
Reviews for "The Witch's Wisdom: Harnessing the Knowledge of the Sword in the Stone"
1. Sarah - 2/5 Stars - I was really excited to read "Witch in Sword in the Stone" as I love fantasy novels, but unfortunately, it did not live up to my expectations. The plot was confusing and convoluted, with too many unnecessary subplots and characters that added nothing to the story. It felt like the author was trying too hard to create a complex world without giving enough attention to character development and a solid plotline. Overall, the book left me unsatisfied and wanting more.
2. Michael - 1/5 Stars - "Witch in Sword in the Stone" was a huge disappointment. The writing was incredibly dull and lacked any spark or creativity. The characters were one-dimensional and lacked depth, making it hard to form any emotional connection with them. The pacing was also way off, with the story dragging on for far too long without any significant action or development. I found myself struggling to finish this book and would not recommend it to anyone.
3. Emily - 2/5 Stars - While "Witch in Sword in the Stone" had an interesting concept, the execution fell flat for me. The writing style was overly descriptive and dragged down the pacing, making it difficult to fully engage with the story. The characters were also underdeveloped and lacked any real personality or growth throughout the book. Additionally, the dialogue felt forced and unnatural, making it hard to connect with the characters and their interactions. Overall, I found this book to be mediocre and would not recommend it to others.
4. Alex - 2.5/5 Stars - "Witch in Sword in the Stone" had some promising elements, but they were overshadowed by the numerous flaws in the story. The world-building had potential, but it lacked coherence and left many unanswered questions. The plot was confusing and disjointed, making it hard to follow the narrative. The lack of character development and depth also made it difficult to care about their journey and outcomes. Overall, while there were glimpses of potential, this book ultimately fell short of my expectations.
