Damaged .cr2 files



a blog for and by digital imaging specialists
I’ve been trying to give C1 Pro4.5 a fair chance, despite my diss-satisfaction with it.
I decided to trial it on a job this week
I Shot tethered with Canon 1dsmk3 to a macbook pro 10.5.5. All the files were fine upon import (they rendered at 100% and I processed Low Res Jpegs)
The Images were fine when editing.
But after editing I went back to process some Hi res files and about half the images in the shot folders were corrupt (large blacked out parts of image, incorrect file size)
I was unable to recover these images, I was backing up after each shot. The backed up copies are fine, and I’m now using 3.7.9 the process these files.
I’ve had my laptop checked by apple who have not reported any drive problems.
The only application that was used to handle the files was C1pro4.5 apart from finder.
I’ll be trying to recreate this problem in the office over the weekend.
I’ve also started a support case with Phase One, and posted this on their user forum (of which there are a number of people with a similar problem)
I WOULD WARN PEOPLE NOT TO USE THE CANON 1dsMK3 WITH 4.5PRO UNTILL THE CAUSE OF THIS PROBLEM IS ESTABLISHED

This is a question i wanted to ask……
How do Phase One RAW files handle in Lightroom 2.0 and Bridge CS4
compared to C1 pro ? In particular how do skin tones and color turn out in the RAW processor ?
I am interested in this because i am starting to use Lightroom more and more since
C1 pro 3.7 hasn’t developed in ages and getting my hands around the clunky C1 4.5 seems daunting.

Saw this article on Patrick Lavoie’s workflow article here

One of the “perks” of a freelance tech is that occasionally you get to see some other person’s workflow. For me, it’s always cool because just seeing a different approach often makes me think of how to improve my own. It would be fair to say that my routine has many bits and pieces I’ve learned from others along the way, and for that (and to them) I’m very thankful.
Now the flip side of this is when I get on a machine and seriously have to wonder what the “tech” before me did–ever see a process folder where someone renamed WITH NO EXTENSIONS? Or, how about finding a session buried deep in the “documents” folder, because hey, that’s really intuitive ( you know, image files and document files are basically the same; 1’s and 0’s right?). I think my all time favorite is the person that managed to overwrite all the files in their backup capture folder by syncing from a different empty folder and choosing to sync deletions, but not before having permanently deleted the original capture session. WTF people? 1) don’t ever delete anything until you are absolutely sure you’re backed up, and 2) option(or shift-cmd) delete? That’s like pulling the pin on a hand grenade. Always give yourself a way back, just in case because shit stuff happens.
I digress.
The point of all this is I had to laugh when I came across some tech’s exposure warning settings in C1 the other day and they were set at 251 and 7. Wow, that gives you alot of headroom; like none. To me the whole point of the exposure warning is that it’s a warning and you might need to adjust a few things to get the optimum image information. Having it set at the extreme edges doesn’t really help. In fact, I like to be conservative so that when the photographer asks if it’s okay, I know that I’ve got a little more leeway and can decide from there–I’d rather have more information than less any day. Target custom colors is really more of a software band-aid, and setting it at 253 and 10 will definitely get you information there, but I’d rather be old-fashioned and have them move a lightstand or dial up a pack instead. That said, there are times the client wants Target Colors set at certain parameters, and what they want, they get.
Me, I’m sticking to 243 and 12. Conservative? Maybe. But of you’ve ever silo’d 300 images and seen the bloom, you know where I’m coming from.
It appears that Mamiya has an “open” relationship with Phase One as their new Digital Cameras System – The DL 28 incorporates the Mamiya 645AFD III and a 28MP Leaf Digital Back. The Mamiya DL28 will be available November 2008. MAP price is $14,999. You can read more about the new system here: http://www.mamiya.com/news-events-press-releases.html
Innovative digital technology and the heart of a classic.
Leica has once again revolutionized the world of photography with a digital S-System that’s perfect for professional use.
The Leica S2, with its premium AF objectives including everything from ultra wide to super telephoto, is an absolute photographic highlight. The digital SLR camera has a special new sensor with 30 x 45 mm and 37.5 megapixels. The S2’s metal body is appreciably smaller and easier to carry than similar models from other camera brands, and yet it’s also nearly twice as fast thanks to ultra modern processor technology.
With the S2, Leica has created an entirely new class of camera – technically innovative but incredibly flexible thanks to a wide selection of accessories. It’s a must for every professional photographer who is looking to upgrade from standard 35mm SLR systems.

Apple has just released their new MacBook Pro which sports a new design similar to the MacBook Air and like it, has a surprise inside – No more Firewire 400 port. This could create problems for users of FW tether devices (as well as hard drives), but more than likely FW 800 adaptors will solve the problem, making it more of a unnecessary annoyance than an actual problem.

Well gang, here it is:

I’ve installed on both my laptop and tower stations, and will be testing extensively these next few days, so I’ll have plenty of questions for the Phase crew at PhotoPlus next week.
So far, the install has gone smoothly, and the license activation was a breeze. I’m happy to report that the User Guide, at about one hundred pages, is much more helpful than the previous versions. I’m current with all updates, so I’ll let you know if I’ve shot myself in the foot or not. I have started to make my clients aware of the new release, but won’t move anyone over until I’m sure this is a reliable upgrade that I can trust on set.
BTW, Eric I. is the Canon guru. Most of my time is on set with mfdb’s, so the million dollar “Does it tether the MkIII” question is in his court. I’ve heard it does, but have not personally confirmed it. If it does, great. Have fun connecting with that teensy spaghetti usb cable.
IJFR – Instant JPEG From RAW extracts the jpeg preview from raw files. Most off the time this isn’t really good enough but its super fast and free so it probably worth having on hand for those times that in camera jpegs are enough for FPO’s. get it here
