Camera Response Curve file format

Hi,
is there any documentation on the rcv file format used to store camera response curves and what its data represents?
In my case the content is:
HDRMergeResponseCurve_2.0
Canon-Canon EOS 5D Mark II
4 Y coefficients
-0.029127
0.428257
-1.513274
2.114144
I need to use the response curve outside of Photohsop. How can I use these 4 coefficients to map pixel intensity to linear data?
Thanks!

Harold,
The short answer is good. Actually, it is very good.
I found the differences in color accuracy and computer work time after creating a color profile to be quite noticeable. I have my camera's profile set to default in ACR. I was wondering about this being something of equal benefit.
Thank you.
Bill

HDR problems, inconsistant results and camera response curves

So, I'm doing some HDR panoramas, and every once in a while I'll get one set of merged files looking completely different than the rest of them, usually brighter and with higher contrast. When I look at the 32 bit HDR processing option, I notice that the camera response curve is totally different on the malfunctioning HDR merge shot (10 paritioning lines in the histogram instead of 8). I am shooting RAW with a Canon 60D and Tamron 17-50mm f/2.8. I am in manual exposure, manual white balance, highlight tone priority off, no flash, everything that that be set to manual is set to manual. Sometimes it seems that the malfinctioning set of shots is the one that is not pointing at a bright light source. If everything in the camera is set to manual, how can Photoshop Merge to HDR tell if a shot is less bright than another? Is my camera making a different Camera Response Curve for these less-bright set of photos? I tried saving a Camera Response curve, and applying it to the other sets of photos, but that didn't work. I am using CS5.1 on a brand new computer, but this was happening with CS5 on my slightly older computer a few weeks ago as well.
I'm out of ideas.
Has anyone else experienced this?

Thanks Marty,
I have seen other threads that describe and show the results you are getting, but my inconsistancy is just a stop or so brighter, and a completely different contrast curve. And it's usually only in shots that dont have a bright reflection or the sun shining in the camera.
It's very important in panoramas that each shot has the exact same exposure and processing, so if one set of HDR exposures in a panorama is being interpreted differently by the software, it ruins the whole panorama.
What I really need to know is, is it a camera setting that is making Merge to HDR interpret these sets of exopsures differently than the others, or is the Merge to HDR software interpreting the brightness and contrast on the images on it's own and making a change to the settings based on some sort of automatic level adjustment that I don't know about.

Unrecognized file format

I'm using a Fujifilm s1500 to upload photos to iPhoto. I've uploaded with this camera several times now with no issues. After trying to upload my latest pictures several times, I got the same response: "unrecognized file format." 4 pictures uploaded, 45 did not.
I was looking through the discussions, and tried the suggestion of using image capture. It looked as if all the pictures transferred, but when I opened the folder, there's nothing in it.
Does anyone know why this would all of a sudden happen? All the photos are .jpg. Any thoughts on what I could try next?
Thanks

Directory damage...so that doesn't mean the photos are lost, just somewhere the data has gone awry?
Doesn't necessarily mean they are lost...
I'm just wondering because I can see the pictures in iPhoto, just can't import them.
It's probably seeing a jpeg preview that written to most files by the camera
Also, any reason why the camera connected to the computer won't show on the desktop?
Well assuming it has in the past... Directory damage. However, some cameras don't mount in the desktop at all. Canon cameras for instance.

IMAQ Vision - Writing Image Files: File Format

Hi,
I want to save some images in LabView 5.1.1 - IMAQ Vision 2.2.1 acquired by
a camera. Several file formats are supported:
BMP, JPEG, PNG and TIFF
For me the PNG format seems to the most attractive one as it provides
lossy-less compression and platform independentness. But, in the manual
there is a comment which I don't understand: It says that the PNG format is
not recommend for precise gauging or inspection measurements - and that is
exactly what I want to do.
I always thought that once an image file is loaded into LabView there is no
difference regarding to the file format the images were saved in. Can anyone
explain me, what the problem of the PNG format is? Which format can you
recommend for preci
se gauging instead (BMP?)?
Thanks,
Gerd Simons

one correction:
I use IMAQ Vision 5.0 and NI-IMAQ 2.2.1.

What's the best choice re video file format in a camera for iDVD production

I currently am using a Sony DSC H1 digital camera which does shoot video in MPEG 1. I use MPEG Streamclip to convert those clips to MPEG 4. The results on my TV screen after processing through iMovie and iDVD are "acceptable" but I will want to upgrade to a good video camera at some point to expand my capabilities. My question is - what video file format should I look for in a camera in order to produce the easiest to work with and best quality result from my iMac?? I am using iMovie HD 5.0.2 and iDVD 5.0.1. Thanks for any suggestions.

miniDV
that's what the iApps are meant for...
a superior pic quality can be accomplished with socalled 3ccd cameras, as from Panasonic...
HD (=HiDef) offers much more detail/quality, but is (yet) not supported natively to any disk-delivery format (Apple supports the BluRay consortium); external BluRay Burners (=$$$$) come bundled with a special HD-edition of Toast7...

PSE 9 cannot export camera raw edited files to a jpeg format. Only available save as formats are photoshop and tiff.

In PSE 9 I am currently unable to save files that have been edited in camera raw as jpeg files. When I try to export the file using 'save as' the only listed options are versions of photoshop file formats and tiff - jpeg is not listed. I did not have this problem previously when using Nikon D3000 camera. I now use a Nikon D7100. I have installed the 6.5 Camera Raw update but this has not solved the problem. I would appreciate any suggestions for resolving this.
Margaret

You have a 16-bit image and jpeg is an 8 bit format. You can set the raw converter to export as 8 bit by using the pulldown menu below the preview area, or you can just go to Image>Mode>8 bits/channel in the editor.

I just purchased the new Canon SX60 camera. Despite downloading and installing the latest version of Adobe DNG converter, I receive an error message saying that Photoshop CS4 can't open up/convert raw files (.CR2). This is the same file format as used by the SX50, with which I never had any problem. Does anyone have a suggestion on how to fix this problem? Thanks.

Hey Gurus I've just shot a seminar, three cameras, Cannon's reasonably new XA20HD's. File format 1920X1080 MP4 17mbs 25 frames. Am running PremProCS6. I import the files into Prem, they come in ok but will not display. Got a yellow bar and a yellow Media Pending screen. What the? Have to cut this stuff soon! Wont even import into Media Encoder. Says there are no usable streams in the media! Just saw a podcast title about stress in the editing business. Better listen to the one! Any help would be most appreciated. J.

Copy ALL contents of SD card to a folder on edit hard drive. not just video clips, everything. Then in Premiere, import using Media Browser (tab at lower left of Premiere screen). This usually does the trick. There is metadata contained in the SD card files that is needed, not just the video clips alone.

Photoshop Elements 10 plug-in required for the new Camera RAW file format used by the new Canon 6D

I have a new Canon 6D and prefer to use Camera RAW. This new file format is not compatable with Elements 10. A new plug-in maybe is required.
Can anyone help?
Regards,
gordo422209

I can't find Canon 6D in the list of supported cameras for even ACR 7.3. I would thus suggest you converting your raw files to dng using dng convertor tool and then open the dng files in ACR.
Download and install the free Adobe DNG converter to convert your raw files to the Adobe universal Raw format and the files will open in all versions of PSE (keep your original raw files as backups and for use in the manufacturers software)
Windows download click here DNG Converter 7.2
Mac download click here DNG Converter 7.2
You can convert a whole folder of raw images in one click. See this quick video tutorial:

Either use 'SYLKPIX Developer Studio SE' to develope the RAW files and to save them in another lossless format like TIFF, or try if Adobe's free DNG Coverter can convert your Lumix RAW files to dng. Then import the dngs. This way, your files will still be RAW files. This works (most times) for my Lumix FZ28.

Does CS6 or Elements 11 camera raw plug-in support the panasonic raw file format rw2

Hi- I am thinking of upgrading to either one of these products as my current versions do not appear to support the panasonic raw file format rw2 but would like to know if the latest versions do support this format before I buy.

Note that CP's correct answer implies the fact that each individual camera model must be supported by ACR. You can't go just by the format alone. "RW2" alone is meaningless. Bear this in mind when you move to a newer camera. Check the ACR compatibility list first:

Olympus Stylus 1 File Format & Camera Raw

I've just installed Photoshop Elements 12 and the Camera Raw version supplied does not recognise the Olympus Stylus 1 raw file version. I usually use a Canon 5D mk 111 so that raw file format is fine. Does anyone know if the latest version of Adobe Camera Raw knows works with the Olympus file format and if so what version of Camera Raw do I need to download?
Regards, Brian.

Hi,
You need at least ACR 8.3 - just go to Help -> Updates and it should update your elements - ACR 8.4 has now been released.
Check your version of ACR by going into the editor and selecting Help -> About plug-in -> Camera Raw

Recent camera update did not do all raw file formats of new Canon 5D2

The last camera raw update addressed only one of the three raw file formats of the new Canon 5d Mark II.
Why only do one and not all three?
The other two raw formats that need to be done are sRaw1 and sRaw2.
Thank you for your support.

I'm recording video on JVC HD camera.Every 13:54 it starts a new file.I have one file that won't play.I get this message:Quick time player can't open (names file) because the movie's file format isn't recognized. Only happens this one file.Ideas?

I can't open one Quick Time movie file. It says: Quick time player can't open (names file) because the movie's file format isn't recognized. Only happens on this one file. All the others of a two hour shoot are fine.
Any ideas what's happened and is there some way to open that file and retrieve what's on it?

Thanks this was useful. I have been ripping my audiobooks and I was finding that they would get uploaded to iCloud in the process, which in itself was fine, but then iTunes would not let me change the media type to Audiobook, which is annoying as it effects how iTunes treats the media. Like showing you the skip back 10 seconds button.
The general outline here helped me work around the issue and change the media type before the media was re-uploaded to iCloud.
