Title: ACR VisionLog Camera Profile
Post by: newsense on March 01, 2016, 07:31:24 AM
I downloaded the VisionLog camera profile and placed it in C:\Users\matt\AppData\Roaming\Adobe\CameraRaw\CameraProfiles and C:\ProgramData\Adobe\CameraRaw\CameraProfiles and I still do not see the profile in Adobe Camera Raw.

You don't have to copy it to ProgramData.
Do you have a directoy VisionLog in C:\Users\matt\AppData\Roaming\Adobe\CameraRaw\CameraProfiles and do you have restarted PS?

It looks like MLVFS must have wrong EXIF for my camera, Rebel T4i instead of 650d.

And C:\Users\matt\AppData\Roaming\Adobe\CameraRaw\CameraProfiles was there? You haven't to create "CameraProfiles"?

Rebel T4i is the 650D. If you need to change any tags use exiftool and how that works can be found searching and reading in this forum for instance.

Walter, I guarantee you the dir. Is there. I believe the problem is the camera shows up as rebel t4i instead of 650d.

Download a CR2/JPG shot with 5D3 (or another non-Rebel camera but not 70D) and try to reproduce your issue. If VisionLog shows up: Yes, you are right. If not: Yes, I'm right. And Danne, too.

It was never about me being right, I just want to use camera profiles without changing EXIF data. i'd add the screenshots if I knew how but it did work with the picture I downloaded from a 5dmk3

CanonModelID (Binary)
CanonImageType (String)

Made some experiments: PS does not identify camera types by string values. I changed string exif tags values for Model and CanonImageType: Just ignored. Changed camera entry in DCP: Nope, does not make a match with string entries.
But I can confirm there must be some kind of match between VisionLog DCP files (dedicated to cam) and file loaded into CR/LR. If not matched VisionLog profile will not show up in Camera Profiles dropdown box.
Now I need your file causing VisionLog profiles to be hidden.

Unable to reproduce your error using latest MLVFS for Windows and Dokany 0.8.x.

I'm wondering why you have no profile visible at all.
Just to make sure: You are running MLVFS and have a drive letter mapped to the directory where MLV file is located? And you open those DNGs from the mapped drive (using the letter assigned via "MLVFS.exe" command) with AE?

Can you upload a short MLV and a DNG generated by MLVFS?
Title: Re: ACR VisionLog Camera Profile
Post by: Andy600 on March 04, 2016, 10:27:59 AM
T4i, Rebel, Kiss etc are regional. Adobe use global model numbers so 600D, 650D etc. It's the 'UniqueCameraModel' tag that calls profiles in ACR so make sure this tag is the correct one for your camera in your DNG meta. If not, contact the raw2dng's app dev. If the tag is correct it is 100% going to be due to the location of the .dcp. Make sure you have the latest CameraRaw installed or if you are on an earlier CS version, the last available CameraRaw released for that. Also, there is one unmentionable app out there that doesn't follow procedure and embeds non-standard tags making any standard camera profile inaccessible.

Use this at your own risk.

You could try this script which will put in the canon EOS 650D tag to dng files after they are developed. It needs exiftool installed. You simply put the script next to your folders with dng files and double click.
https://drive.google.com/file/d/0B4tCJMlOYfircXpJNDlhakFCX0U/view?usp=sharing

If the script doesn,t work you might have to give it user priviliges. Go to terminal and write.

chmod u=rwx [drag script here] hit enter

Here,s the script lines
Code: [Select]
workingDir=`dirname "$0"`
cd "${workingDir}"

find . -maxdepth 2 -mindepth 2 -iname '*.dng' -print0 | xargs -0 exiftool "-UniqueCameraModel=Canon EOS 650D" -overwrite_original

Title: Re: ACR VisionLog Camera Profile
Post by: Walter Schulz on March 04, 2016, 01:15:24 PM
Sorry, but this is too fast for me.
I was not able to reproduce newsense's error following the workflow he gave:
650D's MLV mounted to MLVFS, opening DNGs in any Adobe AE. (I tried PS, too). Exifs are just fine, profiles filled up nice and clean.

So: *I* have no troubles, *he* should repair his DNG.
I'm missing something here ...
Title: Re: ACR VisionLog Camera Profile
Post by: Andy600 on March 04, 2016, 01:22:52 PM
It must be profile location Walter. I have seen very rare instances where ACR got corrupted and needed reinstalling but if the meta is correct ACR will assign profiles assuming they are placed in the correct location.

3rd party DCP profiles should not be placed in the Adobe Standard or Camera Profiles folders (or they are ignored) and also not inside folders of folders of folders. I've checked some stock images and MLV from the 650D and all relevant profiles are accessible (OSX and Windows).

MLVFS source looks correct too so it's not that.
Title: Re: ACR VisionLog Camera Profile
Post by: Walter Schulz on March 04, 2016, 01:28:04 PM
But this doesn't match what he told about 5D3 files he tried. Profiles (at least VisionLog) showing up, then.
That's what is puzzling me: Profiles working with non-650D files and not an explanation at hand what could be messing with his 650D's exif data.
Title: Re: ACR VisionLog Camera Profile
Post by: Andy600 on March 04, 2016, 01:43:27 PM
A DNG is certainly needed to verify. In my experience it will be something very simple.

Everything is working here too (with my stock footage). This is a weird one. I don't get why MLVFS would embed a regional tag like this, in fact I'm pretty sure it doesn't.

@newsense is right. Just tried his MLV and MLVFS shows a regional tag  ??? I can't find anything in MLVFS source - @dmilligan?
Title: Re: ACR VisionLog Camera Profile

It,s the tag that mlv_dump is providing as well. Shouldn,t it be adobe that should be able to read this tags?

@Andy600: What? Wasn't able to processed his MLV yet (no MLVFS around right now) but my own MLV does not give me that!
 
Title: Re: ACR VisionLog Camera Profile
Post by: Andy600 on March 04, 2016, 03:00:45 PM
Adobe's DNG Converter always assigns the global model (650D etc) as the UniqueCameraModel tag and a regional tag (T4i etc) as LocalizedCameraModel (if they differ). If there is no regional tag it is usually omitted.

Here, the region tag is being used for both the UniqueCameraModel and LocalizedCameraModel which is why the profiles for this camera are not accessible in ACR but are for DNGs converted from cr2 and possibly other raw2dng apps. The UniqueCameraModel tag needs to be the global identifier (i.e. Canon EOS 650D).

As a temporary fix just change the UniqueCameraModel tag to Canon EOS 650D with Exiftool.

@Walter - you probably have a camera badged as 650D? TBH I'm not sure how this regional tag is getting into MLV in the first place. I can't find anything in MLVFS source but I haven't been through it all.
Title: Re: ACR VisionLog Camera Profile

@newsense: Can you upload a CR2 out-of-the-cam?
Title: Re: ACR VisionLog Camera Profile
Post by: Andy600 on March 04, 2016, 03:16:35 PM
@Danne - Adobe does, I think, try to honor the various localizations by putting them in different tags but they are not obliged to and might not where multiple/duplicate camera profiles could be shown in ACR/Lightroom and confuse users. The basic minimum is that the UniqueCameraModel tag is populated correctly so that profiles can be accessed - with other tags they may or may not be accessed depending on what Adobe did in ACR/Lightoom. There is a logic to it all but Adobe do make things a little complicated.
Title: Re: ACR VisionLog Camera Profile
Post by: Walter Schulz on March 04, 2016, 03:23:29 PM
Okay, understood (I hope). Yes, I have 650D all over in meta and nothing about KISS or T4i.
So maybe we have an issue with MLV metadata using a regional tag and MLVFS converts this - with best intentions - to Unique tag. How to verify/falsify this?
Title: Re: ACR VisionLog Camera Profile
Post by: Danne on March 04, 2016, 03:28:44 PM
Get a CR2 from newsense, convert it with adobe dng converter. Mlvfs grabs metadata from MLV so I,m pretty sure that is what mlvfs is showing.
I,m not totally convinced that the unique camera model tag always is the same as according to Andy600. Will be interesting to find out.
Title: Re: ACR VisionLog Camera Profile
Post by: Andy600 on March 04, 2016, 03:46:21 PM
@Danne - I've looked at meta from a 650D and a Rebel, they show the same UniqueCameraModel but the Rebel also has an additional localized tag.
Title: Re: ACR VisionLog Camera Profile
Post by: Danne on March 04, 2016, 03:51:08 PM
Ok, it seems MLV grabs that tag somehow.
Here,s metadata from a MLV file with the localized? camera model name tag. (Canon EOS 700D)
(https://www.magiclantern.fm/forum/proxy.php?request=http%3A%2F%2Fs18.postimg.org%2Ftku6w5q61%2FScreen_Shot_2016_03_04_at_15_47_26.png&hash=0ec67cc89dfa4e4b346c571d779ac7a7)
Title: Re: ACR VisionLog Camera Profile
Post by: Andy600 on March 04, 2016, 03:55:18 PM
Yes, it's grabbing the localized model header from localized models so there needs to be a function added to raw2dng to parse possible local tags before writing the UniqueCameraModel tag.

I couldn't find it in MLVFS because as you say, it's coming from MLV and I presume MLV is grabbing the header from the camera's internals.

Incidentally, this will affect ACR, Lightroom, RawTherapee and probably apps that use ICC input profiles.
Title: Re: ACR VisionLog Camera Profile

MLV is linked in reply #32

EDIT: I'm out here, I'm pleading incompetence! We have an issue for sure and I think g3gg0, dmilligan, Danne, Andy600 ... will come up with a solution for all Rebel/Kiss users.
Title: Re: ACR VisionLog Camera Profile
Post by: dmilligan on March 05, 2016, 06:29:52 AM
PROP_CAM_MODEL returns the localized camera model. I was already somewhat aware of this, but I had not considered the implications.

I don't like the idea of some hardcoded table of camera names in MLVFS and other converters. The MLV format specification doesn't really go into detail about what is meant by "Camera Name", but there is only one field, so there's no possibility of recording both the localized and unique camera model names without changing the spec.

I am trying to change the exif with exiftool to see if that can work as a temp solution but the script that danne shared doesn't work for me. Anyone know how I can change the exif? I'm using MLVFS to get .dng's
Title: Re: ACR VisionLog Camera Profile
Post by: dmilligan on March 05, 2016, 05:01:24 PM
MLVFS dngs are "virtual", you can't change them unless you copy them out of the virtual filesystem thus turning them into real files.
Title: Re: ACR VisionLog Camera Profile
Post by: Walter Schulz on March 05, 2016, 05:03:43 PM
And the script provided by Danne is for OS X, not Windows.
After copying them to them to a "real" directory, follow this:
Open Explorer, mark the directory where your DNGs are located (and for easy use: Copy Exiftool.exe there). Press shift key and open context menu while pressed. Select "Open Command Prompt here ...".
You will see a command line interface.
Put command in there
Code: [Select]
exiftool "-UniqueCameraModel=Canon EOS 650D" -overwrite_original *.DNGand press enter key.

Title: Re: ACR VisionLog Camera Profile
Post by: Supertouch on August 14, 2016, 04:36:26 PM
Hi,
I have a problem with VisionLog Camera Profile:
- when I open the .dng files with Adobe Camera Raw (7.0) through Photoshop C6 I can choose Visionlog
- but when I open the .dng files in Adobe AE CC 2015 I can not see Visionlog in the menu of Adobe Camera Raw (9.6.1)
It may depend by the different version of Adobe Camera Raw ?
Thank you
