For an AE only workflow it should be possible to do it if you can find and .icc profile that has sRGB/REC709 primaries mixed with gamma 2.2 instead of sRGB TRC. I didn't find one with a quick web search, but I'm sure one has to be out there. I think I will just make my own such. Then you could just use that in AE and it should be good (at worst if you used that for the output conversion profile that should force it to work out).

Thank you for sharing the tip.

In AE, I set the project to HDTV (Rec. 709) in Color Management within Project Properties. When I rendered this to a Quicktime DNxHD file, the result was indistinguishable from what I had with no color management selected. Am I missing something, or does the color space conversion occur automatically in AE or upon rendering?

Did you use AE only?
ACR in AE probably was maybe using sRGB.icc and the file was already using sRGB TRC at that point so using no management vs REC709 maybe didn't matter at that point. So I'd expect the same outputfile in that scenario.

But what programs did you use to play the DNxHD file back with that made them look exactly the same as they had in AE when REC709 working space was set? Was it MPC with full color management plug-ins?

Are you talking mac or pc?

PC but I doubt that it makes any difference. If you use different programs then it's a whole new game of course, but I don't see why PC vs MAC should make any difference (maybe most MAC video players are color managed?? even so they'd look a bit off on the avg HDTV or PC though)

1. Canon 24-70 II
2. Canon 70-300L
3. Canon 300 2.8 IS (+ 1.4x TC +2x TC :D)

...working with the DNGs in Lightroom is still really useful though. I find it much easier to tweak and do cool stuff....
I also like using Lightroom better, but some people have reported that using Lightroom with 2012 calibration can cause flicker as it appears to apply some tweaks on an individual image basis.
@LetTheRightLensIn
Please keep us updated with your findings/thoughts on the color management/workflow! Thanks :)

Yeah I am noticing that for certain clips it (ACR 2012 whether through LR or PS apparently since you mention LR and I use PS) does introduce flicker. For now I pretend it is a flickering film projector ;).

Not having use the 5d3 raw or anything, but couldn't you go into Library module in Lightroom and make the individual frames fairly small (I'm guessing they're displayed as an entire set of individual raw images) and just scroll through them quickly to see if there are any that have significantly different exposure to find those flickers?

Tricky when like 300 out of a 1000 appear to. I think some of it was actually there in real life though I think some bushes were blowing around and rapidly changing the lighting in the scene. I think 24fps makes it seem more strobe like that in real life and ACR probably did accentuate it a bit though too.

Claiming readers are clamoring for more video news coverage, the Chicago Sun-Times has dumped its entire photography staff.

http://www.chicagotribune.com/business/breaking/chi-chicago-sun-times-photo-20130530,0,4361142.story

Seems a bit drastic, and probably related to short-term budget thinking, but it's what I'm expecting to see long-term. Still photos are going to struggle to maintain relevancy.

They're going to use stringers/freelancers for some still photography in the print edition, I guess.

Wow, that is a bit much and that is a major paper too, wow. Seems a bit nuts. man.

Yes..  I was thinking the same thing....  This is great for hobbyist...  But pros really can't us it as effectively as 3rd party devices to control the camera won't work with it.

Does it really prevent anything? For now it prevents full scale external monitoring until they make it work with 1.2.1, but people did have that all this time anyway.

Hmm... I prefer the Canon one over the Magic Lantern one.

Give it a real try and you will NOT say that.

It depends what you mean by a real try... On a typical day I might shoot 150 clips. Processing each one of those using the current methods for getting raw video out the 5dm3 would be 1) a massive pain in the ass 2) so time consuming that it isn't worthwhile for anyone actually making professional work.

At the moment it's amazing for hobbyists (or other people for whom time doesn't equal money) - but unusable for anyone who makes videos for a living.

Yeah but the other guy was talking about output quality not workflow.

If you are really small or hobby then it is workable or if you are really big it is workable. If you are shooting like crazy for money and just barely getting by and barely able to keep up with even current workflow to get enough money in then it's probably a pretty rough or probably impossible way to go though yeah. But if you are in quite in that situation it should be possible, especially if you get some big, fast RAID setups going and higher-end PC.

I mean it is more of a pain, especially since even quick previews are so now (but already some attempts at rawtodng that also make quick preview files are being tested at which point you'd then be able to quickly scan stuff you shoot without all that much more extra time being needed). In some ways the RAW is so good it can make color development a breeze. But with slow HDs and an old computer it would take ages and yeah be a rough go for some, too rough in many cases.

Does anyone know if the ML's ISO improvement in recording is carried through to the same degree of improvement in RAW still images?

Not at all. It is not magic. All does is get around the step where something nasty gets done to the video and lets you get RAW for video while before you could only get RAW for stills. It can't make the sensor any better than it is and for stills Canon already let you access RAW and they were already getting the best possible from RAW.

For those complaining about the Komputerbay memory cards: DO YOUR RESEARCH.  It clearly states on the product info that the 128GB cards have slower write times than the 64GB cards.  Don’t just blindly buy any card that says 1000X, that rating comes from the READ speed, not the WRITE speed.  (as it has since I’ve been using CF cards on the original 5D)

I have a 64GB Komputerbay card, I was originally a skeptic but, it works just fine.  I’ve already shot over 256GB of RAW video with zero issues.  The 64GB card is the one to get right now.  If you need more space just get a couple.  If you need to do single clips longer than 64GB in size…you would probably be better served by the crappy on-board video.

Also, these cards seem to use the same chips as the Sandisk ones…so enjoy paying for brand names.

The place where I ordered my KomputerBay advertised a "minimum 90MB/s write speed", which was not accurate and I am returning it today. No big deal. On a side note, James Miller shot part of his "Genesis" video using this card (shooting 1920 x 720).

I ordered a Transcend 1000x 128GB about 10 days ago. It just arrived. The fastest write time I could get was around 83MB/s. It's not useless, but it won't get 1920x1080. I'm returning it today. No big deal.

Fortunately, I have a Lexar 1000x 32GB and a Hoodman 1000x 64GB, which both write in the low 90s. Next up for me is a KomputerBay 1000x 64GB (probably sold out most places by now). And then I'll be on the prowl for a Toshiba.

Wow, that sucks!  What site was it?  Amazon lists the write speeds, thankfully, or I would've suffered the same fate!  I almost pulled the trigger on the 128GB until I saw that.

I'm hoping fast cards come down in price soon, I have an 8-day climbing trip to Canada in two months and I'd like to be able to shoot more than 7 minutes of RAW video!  lately I've been just lugging my laptop along and transferring to it as my one fast card fills up.

I keep shooting 1920x720 on accident, I wish the ML firmware would default to 1920x1080 instead of 1920x720...oh well, beggars can't be choosers!

There are definitely fast, bigger cards (Transcend) but I'm trying to save up for a new wide-angel prime so I'll hold out for now! (I'd feel like a chump paying over $300 for a freakin' memory card!)

So far:

BAD:
 Sandisk Extreme Pro 90MB/s UDMA6 32GB are no good.
 Komputerbay 1000x 128GB UDMA7 150MB/s are no good.
 Basically forget anything rated less than 1000x or without UDMA7 and even at UDMA7 and 1000x, the 128GB     cards are more likely to be suspect as are less than ultra-premium brands  it seems.

GOOD:
 Lexar 1000x 32GB work
 Hoodman Steel 1000x 64GB work

Newer builds can shoot more than 4gb clips now.
for cards formatted in camera(file size limit of 4gb for those cards), it will automatically split the clip at 4gb
for cards formatted with EXT(probably completely wrong about the format name), it can record a single clip as big as your card

the newest builds of raw2dng can extract both.

Are you referring to exFAT? I didn't realize the 5d3 supported exFAT.

The 5D3 does (although it won't format to that in cam). You need to format the cards on your computer to exFAT and then, with the later versions of ML, you can record over 4GB.

The difference is amazing, especially at high ISO.

What is the H.264 doing to the image to destroy the contrast and brilliance of the color?

It is not so much the h.264 they use since even going HDMI clean out to Ninja 2 it still loses a lot of micro-contrast and color. Something they do in the image processing chain after it gets fed raw to liveview and before it hits the h.264 engine is knocking it down hard.

EOS Bodies - For Stills / Re: Real iso's?
« on: May 28, 2013, 09:37:22 PM »
I did an ISO test with my 7D.

Put the camera in a dark room (basement) leave the lenscap on, close/block the viewfinder, use RAW or disable ISO long exposure/noise reduction. Choose the settings that you want (Manual mode). Take every picture for at least 10 seconds and you will come up with al list like me.



The 7D is an 18MP camera which is equal to approx. 18MB file size. (the smaller the file size, the cleaner the image is)

As you can see is ISO 160, 320, 640 the camera's sweet-spot... The golden rule is that the limit is MP/MB+1(file size) so 19MB is in the safe/clean zone and 20MB is pushing your camera. It's no math, just hard numbers.

MxM

Don't forget that the clipping point also shifts though. ISO160 is nothing more than over-exposing ISO200 by 1/2rd stop (in RAW). So for RAW it really doesn't matter. For JPG and movies it can matter though because of how they apply the tone curves.
