Canon 5D Mark III = Light Leak & Exposure warning

For those keen on the new 5DM3.... a warning about the exposure metering.
It's been reported that using the LCD light in dark environments will affecting the metering.
Ambient light on the top LCD will enter the exposure metering circuits to again mess up the metering...

Hmm... does this mean the camera can't be trusted outdoors in bright light, nor in total darkness?

Hi xl,
Sorry for the delay in responding on this. I believe you are correct, and that Canon is working on a resolution to this problem. I know you’re a Nikon user, but if any Canon shooters have any concerns about this I would suggest contacting Canon directly.

Canon 5D Mark III - underexposes

Hello,
I've noticed that my Canon 5D Mark III underexposes somewhere between 2/3 stops and one stop.
I've taken a test photo and I've attached the histogram and the exif. I photographed a white sheet of paper
Is this behaviour normal or is there a problem in the camera's metering system?
Thanks,
Catalin

You are in partial metering mode, which is fine if you are shooting a plain white piece of paper. However most of the time I'd recommend either Evaluative instead, or if you are more accustomed to it, Center Weighted. Or use Spot Metering in some cases. Partial is sort of like a "Large Spot Metering" mode.
Evaluative has the advantage of putting extra emphasis on the area right around the active AF point, i.e. presumably around your subject. The rest of the image area is considered, too, but more weight is given to the active AF point. Center Weighted metering doesn't do this (it's sort of an "old fashioned" method of metering, but some people are accustomed to it from using older cameras.)
Do a Google search on Expose To The Right (ETTR), which is a common technique used by Canon shooters. Like hsbn mentioned above, I think Canon is a bit conservative about their metering, erring a little toward underexposure to "protect the highlights". This was a good practice back in the days of slide film, but is just the opposite of what you want to do with digital. To minimize noise in images, it's better to slightly overexpose and pull the exposure back down a little in post processing. Not a lot... just +1/3 to +2/3 stop. Here is a link to one of the better descriptions of ETTR I've seen. There are other tutorials and discussions about it other places online, so do a search if you wish.
Oh, and there was an exposure issue with the 5D III early on. The problem was a light leak near the top LCD, that would cause underexposure from additional light reaching the metering array in the viewfinder. Canon did a recall made some changes to fix the problem. Yours would have to be a very early production camera that was never fixed under the recall, to have this problem. The problem would vary, depending upon how strong light was striking the top of the camera whle shooting. Outside on a bright sunny day would cause more error than shooting indoors in low light.

Not able to open raw files from my CAnon 5D mark III in PS CS6!

I have camera raw 8.6 installed and am running photoshop cs 6.0. All of a suddened photoshop will not open raw pictures that were shot on a CAnon 5D mark III. Any ideas on what could be the problem. The pictures do open in light room.
Thanks
Bruce

What exactly happens when you try to open raw files from Canon 5D Mark III in PS CS6. Do you get any error message? An error screenshot would help.
Make sure your PS CS6 is up-to-date from Help > Updates.
Restart the machine and retry.

Canon 5D Mark III back screen is dead after tethered capture with Lightroom 4.3

I was successfully shooting tethered using Lightroom 4.3 (PC laptop with Windows 7) and my Canon 5D Mark III, however when I disconnected the cable I was no longer able to see anything on the back of the camera, no image playback, no menu, no live view, nothing. How do I recover the functionality of the camera's back screen. I tried removing the battery for a while, replacing the battery, taking out the memory card. Don't know how to "reset" the camera. Note the top display on the camera and the view finder display work fine, I can change settings with my dials. Was working in Manual Exposure mode, and also tried Aperture Priority. If I reconnect to the laptop I can still work in tethered mode, but after disconnecting the camera back is still dead.
Was I somehow supposed to disconnect the camera from tethered capture before disconnecting the cable?

It is probably not related to your tethering session in Lightroom. It is also unlikely to be related to the order you unplugged things. (Unless you yanked the cable and damaged some electronics).
Have you tried pulling both batteries for 30 minutes (The regular battery and the quarter-sized watch battery)? Pull those and the memory card. Unplug all cables and let it sit for a while and then replace the batteries.

I tested my new Canon 5D Mark iii with my 85 1.2 L lens. The images look terrible! What gives?

I just purchased a new Canon 5D Mark iii body. It is replacing my 1Ds Mark ii. I tested it with my 85 1.2 L series lens. I took the RAW images into Capture One 7 to look at them. I was highly disturbed at what I saw. The quality was no where near my Canon 1Ds Mark ii. The images seemed somewhat soft even after applying a consderable amount of sharpening. They also looked flat and lifeless, even after pumping the contrast and adding Clarity. All in all they looked terrible! I must have something wrong, as I have read countless times that the new chip gives incredible results.
When first attempting to set up my camera I set it to Adobe RGB and for RAW images only. I noticed that you seemed forced into deciding on a specific "Picture Style". I left it on the default settting of "Standard". Should that effect my RAW files, or is that bypassed altogether when shooting RAW? I noticed that in "Standard" mode that some in camera sharpening was applied to the files. Is that my problem? Should that be turned down to zero, as I would normally do all my sharpening afterward either in Capture One 7 or other software. I shot all my test images with fast shutter speeds so that is not the issue. This lens is in perfect condition and has always produced incredibly sharp contrasty images. What on earth could be wrong? Any suggestions? I am a professional shooter for the last 20 years, so this is really perplexing me! Help!!!

Hi Corey,
Picture styles are ONLY applied to JPEG images or video. They are never applied to RAW. Canon will "tag" the meta-data of the image indicating picture style choices so that desktop processing software that understands those choices can apply it after-the-fact. But the point of "RAW" is that the camera will not perform any change to the image which would result in a loss of original data.
As for the soft focus... the good news there is probably nothing wrong with your camera or your lens. It probably just needs a slight focus calibration adjustment (you don't even need to send it in for this.)
The camera sensor is analogous to a movie screen. If the image is blurry... it's not the movie screen... it's the movie projector (or the focus). However... keeping with that analogy... suppose we focused the image perfectly... but then moved the project a foot closer to the screen. The result would be a slightly out-of-focus image even though there is actually nothing wrong with the projector.
The phase detect focus sensors are on the floor of your camera. When the reflex mirror is down, some light is bounced down into those sensors to focus the image. The distance to the AF sensors vs. the distance to the real sensor is supposed to be calibrated to match... but it's actually possible for the AF sensors to think the image is focused when it's really slightly out of focus on the sensor. For this reason, your camera has auto-focus micro-adjustment capability -- in other words this is something you can test and tune yourself. The REASON you might do it yourself is because it turns out it can be different for every lens (even two EF 85mm f/1.2L lenses in a row might have slightly different focus). This adjustment is only available on the mid-range and pro bodies -- it's part of the reason you buy a premium body. The camera can actually remember the AF adjustment for each lens uniquely.
See this article: http://www.lensrentals.com/blog/2008/12/this-lens-is-soft-and-other-myths
Or this article: http://www.luminous-landscape.com/essays/are_your_pictures_out_of_focus.shtml
BTW, to test the lens, I'd suggest getting a focus calibration target. You want controlled conditions when you do this -- don't shoot typical everday subjects because it wont be precise enough.
I use a DataColor Spyder "LensCal". The LensAlign products are also popular.

Does PSE11 show HDR exif data for a Canon 5D Mark III?

I have taken some pictures with the HDR feature on my Canon 5D Mark III. The HDR image that the camera creates does not show that it was created using the camera's HDR feature when viewed with PSE11. The Canon Software that came with my camera is ImageBrowserEX 1.4.0 and it shows these data: HDR Shooting Enable, Adjust dynamic range +-2, HDR Effect Natural, Auto Image Align Enable. Is there a way to show the HDR exif in PSE11? Thanks, Anne

Thanks -- I should have mentioned in my original question that I had already looked at File>Info. The usual stuff is there but nothing about the image being created from the HDR camera function, or at least that I could see. I went through all the tabs including Advanced and just don't see it. I will try to figure out how to ask Adobe Technical Support and how to request that they get that info included if it's not there. Anne

When will finder show a thumbnail or preview of the raw file images from the Canon 5d mark iii?

I am wondering if anyone has an update on when finder will show a thumbnail for the raw files from the Canon 5d mark III? I've done all the updates possible and nothing has changed, I can't do a quick preview either, it just shows the extension image, not the actual image taken. (The symbol for crw).

I had the same problem for a Canon EOS-1D X and finally got around it by viewing the images in Adobe Bridge. Worked beautifully!

Camera Raw 7 does not recognize Canon 5D Mark III RAW files

Hello,
I have Adobe Creative Cloud installed and I use Adobe Photoshop CS6 with Camera Raw 7. Photoshop nur Bridge CS6 do not recognize the RAW files from the Canon 5D Mark III, though it says on the Adobe support site that the camera is supported since Camera Raw 6.7
When I try to open the .cr2-File I get the message "Photoshop cannot open the file".
I use Win7 (64 Bit).
Any help?
Thanks in advance,
Robert

Hi Robert,
Its a known issue as the PS CS 6 was launched with ACR 7 however the support in Photoshop CS 6 would come with ACR 7.1 update which will be live soon.
You are completely right in saying that Canon 5D Mark III was supported in ACR 6.7 but it was only intended for >PS CS 5 & 5.1.
In the meanwhile if you want you can download the RC version of ACR 7.1 from labs.adobe.com.
Thanks

How to import Raw files from the Canon 5D Mark III into PSE12? [was: cr2]

I have Photoshop Elements 12 and I can't import Canon 5D Mark III CR2 files.

Not sure what you mean by view the photos? Are they showing in the camera raw dialog when you choose a CR2 file from the menu in expert mode:
File >> Open
What computer and operating system are you using?
Can you try shooting a couple of new CR2 files and then put them into a folder on your hard drive rather than the external drive. Can you import from that location using the Organizer menu:
File >> Get photos & Videos >> From Files & Folders

Upgraded Adobe LR 4.1, CS6 Beta & got the Canon 5D Mark III, WHEN is next dot release Camera Raw?

I Purchased the Upgraded Adobe LR 4.1, CS6 Beta & got the Canon 5D Mark III, Mac Pro server update to Lion, WHEN is next dot release Camera Raw? My workflow has trippled in time because of this issue. I'm so frustrated with having to convert images in a slowed up piece of crap canon software package and then wait another decade for the newest LR to load the images I could crap fire! Come on Adobe, where's the release? After a few grand you'd think we'd get a better response time. As for Canon, they are not consistant with community software sharing and can kiss my *!! because to leave Adobe hanging sux!
There should be new laws that penalize jerks that screw with workflow!
Time is money, let's go Adobe!

"so there are no Adobe staff here to see your rant."
Oh, they're here and they see it...
BTW this might help?
