The problem with a those Log color space on most cam, is that it is 8-bit. There is a lot of bits reserved for highlights but not much for mid-tone and almost nothing for shadow. It is almost useless in 8bit.

 

Even more, if your shadows and highlight are not using the full dynamic range and you stretch them a lot in post, you'll get a lot of banding.

 

I would use 8-bit Log only in a controlled environnement (eg. studio) where the highlights and shadows use the entire dynamic range.

 

I really think that Log should be at least 10bits.

Hi chauffeurdevan,

You are totally right.  Used controlled lighting today and noticed this to be the case.  I think 10 bit would solve the issue or improve it.  I noticed the controlled lighting has to be very controlled - error can bite you in the butt. 

Under non controlled light, I took 2 shots in front of a window (the light from the window shone on my son).  Exposure was good, the light source was good, etc.  One shot was neutral and the other Canon log.  In my son's face (skin color broke apart between brighter to darker when color corrected - shadows and highlights adjusted).  The neutral held - although under further looking, I noticed very, very slight banding too.

Took a couple of shots of my son.  Used Neutral then Canon Log.  Neutral was fine.  With CANON LOG, when adjusting the shadows and highlights within legal limits, one gets some banding in the image!  Piss me off.  I'm going to do some more testing this afternoon with the neighbor. 

I wonder if the S35 crop mode keeps its resolution through the HDMI out?

 

Would be a sweet little setup, if you get C300'esque 1080p pro-res 4:2:2, for those jobs that don't need 4K.

 

Also, filmman, if you get a chance.. can you see if the S35 crop mode can do 60p? If it does... Then getting C300 quality 1080/60p is a huge plus point.

Hi ScreensPro,

S35 doesn't do 60p.  1080p will do 60p.  Cheers.

Good for you. did your store provide you with a 30 day money back guarantee or a restocking fee? I think Q1 and Q2 are weird times to invest in 4K. However as someone had mentioned shooting 4k for stock footage commissions is not a bad idea. slow mo is underrated. 60p minimum at 4k.

Hi Leang,

Didn't ask about restocking or 30 day.  I plan on using this 1DC for my flic this year .  I needed a mobile camera which can give quality. I'm testing different lighting situations to get a feel as to the horsepower of this camera.  I did some shots outside the other day under a gloomy day - shots were not bad.  I want to take more outdoor shots but the weather is around -20 C.  I'm planning on some indoor shots tomorrow with my neighbor. 

Hey ScreensPro,

Thanks for posting.  Saw that before but forgot about it.  I've been playing with the 4K and I haven't even tried other modes yet such as S35.  

Very nice.  Thanks for posting.

Hi HurtinMinorKey,

You have a good eye.  I looked at the footage a little more.  Behind my neighbor there was a computer box.  The writing is the culprit.  In the original footage no problem - perfect.  In the color grade it suffers  - but the box was not in too much light.  The writing on the box, which is black and is blurred due being out of focus, becomes "whacked out" or looks like banding.  This happened after pushing the footage a little too much in grading.  I guess I could have masked that portion of the footage.  

Thanks Rickg101,

I had a weak moment and thought no guts no glory. I went for it. I'll update how things are as I use it.  Cheers.

Hi HurtinMinorKey,

I'll have to figure how to do the file sharing.  In the background, it was quite dark  and there was some junk sitting there.  The camera sensor is really sensitive and seemed to be flickering abit too.  I'll have to make sure I'm not the issue or if it is a camera issue.  Probably me.  Might have been the rums.  The camera is challenging, and I'm a slow learning.   Cheers. 

I turned to the Dark Side.  Darth FilmMan.  I got stupid last week.  Let me rephrase that.  I got dumber than usual.  I was talking to a sales guy about the Canon 1DC.  I said, "sharpen your pencil, and give me a price that will make me buy."  I bought it -  I still paid too much.  Then I ordered Lexar 1000x cards and another battery from other places.  So I get the camera, cards and extra battery.   At first I was questioning my decision.  Then not questioning myself.  Anyway, I won't keep rambling.   I was putting up stuff on Vimeo but the compression for a non-plus member is not as good.  So I put some stuff on YouTube.  Here's a quick shot of my neighbor.  90 mm lens.  4K footage down sampled to 1080p.  Then uploaded to the Tuber.

Watched it the other day.  Supposedly there could be an "American Version" which may get produced.

Could this lens satisfy most shots?

The main point is Alex will not try the 1DX and will ban anyone on ML if they attempt.

1dc and 1dx .. identical hardware .. just a firmware difference

Don't worry, we won't do it.

I'd go as far as excluding from ML community any developer who would try to do something like this.

Here's what another ML developer says,

we fully understand your position and agree that that this lack of feature is disappointing.
also the technical aspects would be no big deal imho.

but i am sorry to tell you, the Magic Lantern team decided to *not* develop on EOS 1D series.
we devs all agree that this is a totally different price range and we would seriously deal in business cases where we dont want to be active.
see this as a political decision, but somewhere you have to say: "stop!" and the 1D is such one.

the discussion and decision *is* already made, so even your offer of a donation wouldnt change anything.
(i personally dont want to jump into a shark tank, even for money )
i hope you understand our position.

but we of course will continue work on the 5D2, 5D3 and all the other models and will provide you
free feature upgrades for these caneras

Here's Magic Lantern status (from Alex the main programmer).  He is against touching the 1DX.  I cut and pasted below.  I included the web link. 

Don't forget that quite a few hacking projects had serious trouble not because the hackers infringed any copyrights (they didn't, as far as I could tell), but just because they made the job easier for those who wanted to pirate things. See Sklyarov, geohot, graf_chokolo, Sony's comments on 2012 DMCA exemptions etc.

So, just the possibility of making it easier for someone else to infringe Canon's copyrights (e.g. by porting the 1DC firmware) can bring us into big trouble if we would try to port ML on the 1Dx.

=> no ML on 1DX.

 

I'm of the same opinion, but I think we should use the firmware of these cameras to learn a bit more.

This is not OK under neither European nor US laws afaik, because we don't have a 1DX and we are not creating any interoperable product for it, so we don't have the right to reverse engineer it.

Expensive old glass being used for the test.

Interesting discussion.   The 1DX is not an inexpensive camera.  Will there be someone willing to hack it?  Is it even possible?  I used to get really pumped about Magic Lantern and hoped for them to achieve more and more.  They did achieve a lot.  I was hoping for true 1080p, hoping for 422 mjpeg, etc. Has it occurred?  Nope.   It isn't as easy as I thought or as people thought.  Read thru the Magic Lantern forum and you'll see this.  Magic Lantern has said to the public, they'll be staying away from the 1DX.   I think most know the answer as to whether any possible "hacked" upgrade will occur to the 1DX.  That is the reality. 

PS.  Did anyone see the 4K 24p GoPro hack with the interchangeable lens?  How about the Red Scarlet to the Epic hack?  I didn't either. 

So why are there traces of 1D C firmware in the 1D X?

Because the 1DC and the 1DX share some common ground?  stills?  regular 1080p video?  A lot of extra work has gone into the 1DC.  Cheers.

Yeah my bad on that one =P Classic mistake. 4K is looking great though.

Mundo,

I make mistakes continually.  That's something I'm good at.  Cheers. 

Got a chance to play around with this cam yesterday. 4K only goes for about 30 seconds before automatically stopping due to overheating issues. I knew about the overheat meter, but didn't know that the time it took to start overheating was so short.

Need to use lexar 1000x card for 4K.  If not using the correct card then issues.

If it was an over heating issue then it was a defective camema. 

Would people want to risk frying their 1dx if a hack is produced?    Warranty would become null and void.   And legal issues would exist too.  It is their technology.  Sort of like saying hack the Scarlet to get a Red.  I don't think it will happen.  Too many negative variables. 

Red's 128GB ssd costs $1250. 

Red volt costs $195.  (lasts for about 25 minutes?)

Canon's battery costs $169.  Lasts about 1 hour and 15 minutes or 1 hour and 25 minutes (depends on temperature)

Yea, Red has better specs. 

Canon, form factor.  Quiet operation.

Boils down to picture and what a person likes. 

Both will cost.
