​ I wouldn't say it is the opposite. And to be able to raise the blacks in post, you need your sensor to be able to actually record those information. I don't think that raising the MP makes you lose DR, but simply it readjusts the DR of the camera to give you more details in the black (and I believe losing details in the highlights). But I don't believe in a magic "log" profile that will suddenly give you 15 stops of DR when your camera can really only output 10. And for me its not relevant how much DR my camera has. It is much more relevant how it treats blown out and black areas (ex. film like). Overall I am very happy with the DR of the NX1. If there is one thing that I wish Samsung could improve, it would be the banding / macro blocking because it is a giveaway of a digital semi pro camera.

Thanks a lot Ed ! I like the light grading you did on the first shots of your video. I am very curious of the impact on the dynamic range of the "flat profile". Also I wonder if we should slightly over or under expose (like on the a7s log profile) ? So far I'm leaning toward the fact that with contrast at -10 and MP at +15 it is harder to preserve highlights.

Hi all, As other Samsung NX1 users, I find myself looking around for lens solutions. The Samsung pro lenses are fantastic lenses, and I really enjoy using the 16-50mm S lens. However I don't feel comfortable investing in a lot of Samsung glass. I could have a very hard time selling them (I'm french and the NX1 isn't even out yet). The 50-150mm looks like a great option but at 1500€ I'm not sure how safe of an investment it is for my company. Also I have to confess I usually never use third party lenses. So I have been looking around for other solutions. For example, ultra wide angle lens: - Sigma 8-16mm - Tokina 11-16mm I'm looking for an UWA lens, a macro lens, and a good portrait/zoom lens (50-150mm equivalent). However I am not sure which functions I'll be able to keep: aperture, auto focus, image stabilisation (no IBIS for the NX1). So my question: Which mount and which lenses would be the best to fit the NX1 with an adapter (and keeping the AF / IS) ? Thanks to all of you !

Hi everyone, I started running some tests on the new Samsung Firmware 1.2 for the NX1 camera. As a lot of users I was very impatient in testing the new Gamma DR curve, seeing if it would improve the dynamic range of the camera. So far in my first tests I cannot say that I have seen real improvement between Gamma DR vs Standard profile in terms of dynamic range. It is very hard to measure the dynamic range of a camera - especially when you don't have the facility/tests procedures. And I don't. So my tests are definitely not scientific. Furthermore I don't have images to share yet (hoping that will come soon and please feel free to share yours). Now there are 4 settings that can affect the dynamic range in the NX1: - Profile mode (standard, gamma, etc.) - Contrast value (-10, +10) - Master pedestal value (-15, +15) - luminance level (0-255, 16-235) From my early results what I can say is that going to an extreme setting (gamma DR, contrast -10, MP +15) result on losing skin tones and might increase macro blocking in bright areas. I had much better results with almost the same settings, but putting contrast at -5. But you'll also notice that if you take the standard profile and tweak the contrast at -10 you will have comparable results. Also setting the master pedestal at +15 increases the details in the blacks, but you also lose details in the brighter areas (and you might find an actor's face to have some light reflections, and you might lose those details). However it can be useful in situations where you will need a lot of details in the blacks. For instance I had the experience of filming a music video featuring a black actor dressed in a black suit - and very little lighting. This is typically the kind of situations where the master pedestal will come in handy (and good lighting also). I noticed that a lot of people rely on the master pedestal to give this "film look" and personally I don't recommend it. It is often underrated how soft highlights participated in the film look. With a master pedestal at +15 you will lose some of that imho. So these are my findings so far, I know that illustrating with videos would help a lot, but I don't have this kind of time right now so apologies to the community. I will be very interested in learning from your experiences with the new firmware.

A little bit out of topic eh

Played with it a little bit but can't conclude to anything yet - since the firmware upgrade resets all parameters (screen auto brightness, framing mode, etc.)

And its out ! Enjoy

See the iffmpeg solution for mac (ffmpeg also exists for windows). This works very well.

​It seems that the imac retina supports QuickSync but thanks for the idea I'll see if I can run a few more tests and get those results back to the forums :/

There is this box also (170$) http://www.avsforum.com/forum/39-networking-media-servers-content-streaming/1857514-official-popcorn-hour-vten-world-first-4k-ultra-hd-network-media-player.html Its the popcorn hour multimedia player. Will decode hardware HEVC.

Yup thats what I said And from the tests I ran on Final Cut, the iMac retina is MUCH faster than the MBPr.... So I don't know yet if its a software optimisation but I'm gonna send a mail to iffmpeg support.

Nice !

Im thinking a unit bug :/

Mmm just tested iffmpeg on my new Imac Retina (upgraded with the 4ghz processor, 16gb ram and GPU 4gb). It seems to run slower than on my retina 15" macbook pro early 2013. This seems weird. It takes 3 minutes to convert a 15 seconds clip. I think on my mbpr it took approx 3 times the amount of time to convert. Anyone else noticed something like that ?

Did you try reseting to factory defaults ?

Lets hope that the exposure drift fix will be part of this update :/

Been turned off since day 1 on mine... still drifting... However did anyone tried disabling "overexposure guide" ?

Shot a lot with a GENUS ND Filter. Very nice filter. The only thing I disliked was the X pattern at very high ND value. Other than that it was great to use (Samsung 16-50 f2-2.8)

Most of the drift I notice in my videos are on tripod shots - no movement. Weird...

​Im using the latest firmware for both my lens and camera. I'll upload a video when i got time

I again have to concur that this camera suffers from exposure shifts as long as there is a little bit of overexposure somewhere in the frame. I shot a few interviews in NY and latin america these past few weeks and sometimes it was hell. Now this is not a deal breaker for me, but it was very tricky to use sometimes and played with my nerves. But again I love this camera - much more than the GH4 for ex.

It looks like instead of hacks maybe the community just has to ask Samsung... The firmware 1.2 look like a big answer to what the users have been asking for

​90% of my shots (and i shot hours) are free of this bug. It only happened to me in a few weird lighting situation ( in a white lab shooting someone with a white gown). I just redid the shot a few times it was ok. so I dont think it makes this camera "unusable". I am more concerned about aliasikg for instance. ( might keep my gh4 just for those shots that could cause aliasing).

But the GPU is not great :/ However I have to say I'm really hesistating in getting this thing, and then sell it for a new mac pro when Apple updates their line up

You're welcome Unfortunately right now I'm abroad shooting in north and south america - will be back in europe (home) in a week, then only will I be able to test really... From the equipment I have here though, I can definitely say that there is a substantial difference between in cam recording (preamps) vs tascam recording (comparing the same audio.
