  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

"simple and ridiculous" dragon vs Mx test..

Luigi,

do these two shots have the same aperture?

Thanks!

No you do not have the same opening.
But both were on the verge of overexposure in the highlights, just warmed up a bit both burned the clouds.

the sun has arrived. DRagon shines ...
in these two shots I have explained in such a way that the high lights were not cropped and here Dragon makes a huge difference, MX could not push over ..
Having added 2 more shots with 0.6nd

play..

I'm sorry for the flare, but as I moved they were by all parties
 
I also prepared a HDRx to 3 stops. It will take 30 minutes to upload it ..
 
Hans von Sonntag said:
Ok. Thought so. If they had the same aperture the sensitivity of both sensor would be different because the base-brightness is different.

Thanks,

Yes Hans, of course, you can not do anything else.
in MX Open and earn on the face and lose all the high lights, I could not push over ..
As can be seen as Dragon holds everything without any problems.

At some point, how much more reassurance do people need that the Dragon sensor is an improvement over the (4-years-old?) MX sensor? Does anyone expect a test that shows that there is no improvement?

May I kindly raise the actual point behind Denis' request: In wildlife shooting low light, between dusk and dawn, properties of the camera are of especial interest as that's when the light is on its best, and secondly as that's the time when many animals get active. In addition, in stopping motion the sensitivity of the camera is a key issue. Epic-X is a wonderful tool, Dragon even better, and the remaining question for many wildlife shooters to make up their mind on the update is, how good are the low light properties.

Lauri,
that depends on brightness threshold worked.
During the day there are stories, DRAGON wins a lot compared to MX.
Dusk or low light, you have to see what you mean by these words, posted one of your R3D Epic so we can see what you mean with low light, and maybe we can do some comparison test with Dragon.
 
As to all the other suggestions made by a few people here... I dunno if that is even possible, but if it was possible to recalibrate the sensitivity 4 stops down, would that be an interesting thought? That would leave the highlights needing an ND 0.6 more than the current Epic, but then again , I guess that you more often use higher shutterspeeds than the rest of us. Capturing fast moving animals does not sound like an "180 degrees is always best" scenario...

:-) Indeed, and many people in this field are also interested in stills as Epic and Dragon have much higher frame rate than the best DSLRs.

Luigi, once I get my Dragon will be able to test myself, but in the mean time it would be interesting to see a comparison of Epic-X and Dragon images taken outdoors with exactly the same fixed settings during/after the sunset. It would be interesting to see say a sequence of 10-20 images starting from a proper exposure to what still remains in the Dragon image when the Epic-X image looses all the information.
 
just played with davinci

Gunleik. I have a question that I might have missed here, or maybe is a dumb one of mine. If you set the dragon exactly the same as the MX. lets say i.e.: ISO 800, 1/48th, 5.6 regardless of the exposure if it's perfect, under, or over. If you compare both images, do you have a match in exposure to your eyes, OR, due to the higher DR on the dragon you see more light on the Dragon??? this is an Eye question, not histogram.

it might be a stupid question...But I wonder because I see here a few samples that I see more light in the shadows of the subject, and I might be confused.

Thanks

To me Dragon looks 2/3 of a stop brighter. From just playing around, if say both are exposed identically at 800 ISO, I have to bump the MX to 1280ISO to match the visual brightness of the Dragon at 800ISO. Even bumping the MX 2/3's of a stop the Dragon still has more "brightness". Anyone else notice that?

You can try this out on Luigi's images and bump the MX to 1280ISO and flip between the Dragon shot and that shot.

Ok, again, I'm matching levels here for a comparison. This is subjective because I could have pushed Dragon further but for this example, purely matching levels to show the difference. All that was done is a curve on each to match histogram levels. Play with the files and you'll see MX is also noisier.

As you can see, there's just more info in the histogram of the Dragon and it fills out the entire range. Like I mentioned in the post above, inherent brightness on MX is 2/3'rds less than Dragon. If you shoot them with the same exposure at 800ISO, you have to boost the MX to 1280ISO to match brightness levels. Even then Dragon has a bit more brightness as well as much less noise at that point. And obviously more DR.

Thank you Luigi for doing this test!
 
Matt thanks for your contributions to this thread: my goal in 2014 is know my way around an R3D as well as you!

Luigi - you the man. What else can I say?

Thanks a lot Matt!!! That's what I thought but wanted to be sure :) Happy Dragon...
 
Matt I just played with them on my macbook retina...I see it too between 1280 and 1600 for MX to match brightness as Dragon...that's so cool...not to mention the noise gets very noticeable on MX once the brightness is matched with a curve or ISO.

Cool Stuff

Thanks Luigi!!!

yup, exactly.
 
Hey guys...wanted to share a temporary unfinished trailer of my first feature film, and first time with my RED Scarlet as well...I know it is not the topic here, but for some reason, I cannot create my own posts. it shows insufficient privileges for whatever that means and I never get a reply from Red-user customer service....weird. hehehehe

Film is in Spanish. When Official trailer comes out I will have subtitles. Your feedback is very welcome and I hope you enjoy it.
