Output raw image data

Hi,
I'm using an industrialized camera. However, the labview program comes with it can only output 8-bit image. I am trying create a program that will only output the raw data image not the processed image, because I need image that's at least 10-bit. Any suggestions?
P.S. I'm a new user to LabView and I'm using the 2012 version.
Thanks.

Would you be able to modify the existing LabVIEW program by inserting a string indicator before the processing steps? Then you can manipulate the data however you want.
I don't know if this will help, but once you have a binary file, you can read it directly with this:

Hi

Hi, you'll need to use MemoryImageSource.
You read each RGB triple and add it to a pixel[].
Heres the roughg idea.
Hope that helps.

RAW image date not exporting

Hi there
Currently I shoot everything as JPG, but would like to start using RAW on my Canon 300D. I have done a few trials, and find one thing perplexing – if I shoot in RAW the image date shows up in Aperture. When I export and add the exported JPG to my iView catalog, no Capture Date (image date equivalent) shows up. When I do the exact same steps after shooting in JPG, the Capture Date appears without any problem.
Is there a way to have the image date added to the metadata of the exported image?

I'm not sure about this but the problem may be that there are different "flavors" of EXIF data. I believe there's a basic set of data that all camera manufactures have agreed to and then there's custom EXIF data specific to a camera, lens, strobe, or manufacturer.
It may be that Apple has chosen to only support the generic flavor(s) of data while ignoring the custom ones. I think that's why cell phone syncing with Address Book only gets some data to the phone. Pictures, groups, and the like are probably different for every phone and Apple decided not to support it. But I don't know that with certainty.
If you want to see what data is actually in the original and the exported files download a free copy of ExifTool by Phil Harvey from http://www.sno.phy.queensu.ca/~phil/exiftool/
It's a great tool and shows me more data for my Cannon camera's images than Canon's own software does.

Can a RAW image have a colour profile straight from camera?

I am totally confused after having read a host of apparently contradictory materials. If I shoor RAW images, can they already have a particular colour profile imposed on them by the camera? Does not RAW mean 'no profile before being processed by software outside the camera'?
I have a Canon Powershot G11 camera. JPEGs are always recorded with sRGB profile in this camera. But after some e-mail correspondence with the Canon technical enquiry department, they have told me that the RAW images are also recorded with sRGB profile, i.e they already have that profile as they come out of the camera and before they are processed by the Adobe DNG Converter and ACR. Can this be right?
Thanks very much in anticipation of a simple answer!

Usually cameras don't embed profiles, rather they include a simple tag in the exif data "hidden" within the raw file. This can be used by manufacturer's software for default rendering, but has no effect upon the actual raw image data. This is also done with jpeg output, although of course the camera has rendered the image into either sRGB or Adobe1998 depending upon the camera settings.
I generally set Photoshop to ignore exif colorspace tags (File Handling within Preferences), only want to honor a profile if is actually present. Therefore I always set my camera to sRGB so that on the rare occasions I shoot in jpeg I won't have the wrong colorspace in use. Of course for ACR the camera colorspace makes no difference, since the output colorspace is chosen within ACR, no attention is paid (for raw) to the exif tag. I use ProPhoto for most work in ACR/Photoshop to avoid channel clipping.

How can I keep my RAW images from having anything applied to them when I import them?

Hi All,
I shoot with a Canon 5D Mark III and I use a picture profile in my camera that keeps all my images with low saturation, low sharpness etc... but whenever I import RAW pictures into Lightroom, I initially see the images the way I saw them in my camera, then, one by one, when I click on them, they change without me doing anything - like if some sort of preset was being applied, to every photo, one by one -
I don't want this. I want my photos to be as RAW as possible when I import them and I don't want anything to change. I like what I see in camera and Lightroom changes this after import - how do I stop this? I checked in my Preferences under Presets and NOTHING is checked -
Help...
Thanks

This is in the FAQ and is normal behavior. Picture profiles are not actually encoded in the raw image data but written as a metadata tag in the raw file. Lightroom cannot understand these metadata tags as they are Canon proprietary. So Lightroom will show its own default rendering for the raw data. What I would do in your case is to go on one of your images into develop, scroll down to Camera Calibration and select camera neutral (probably the picture style you were applying in camera). Then set this as the default for your camera (hit option and the reset button will change). Newly imported images will now use the camera neutral profile. This is probably close to what you are looking for. It is important to remember that any treatment you select in the camera such as the picture style, black and white, extra saturation, etc. has no effect whatsoever on the raw data. They only get written as metadata tags for canon software and are reflected in the jpeg that is embedded in the raw file. Lightroom takes the raw data (which is basically simply what the sensor actually saw) and apply its own default interpretation.
You should definitely check out the camera profiles in the calibration section. They tend to give more pleasing color than the "adobe standard" profile that is there by default.

Raw image size 2.147 Gb?

Hello,
Is there a dng specification raw image size limit? I would like to save huge raw images. We changed the kMaxImageSide from 65000 to 300000. I know the dng's which are bigger then 65000 per size can't be opened in other dng readers. But also if you just have a raw image 30000x30000 it can be bigger then 2.147Gb. It's depends on bits per pixels. For now we have images like 7500 x 60000, but soon we want to save raw images like 7500 x 314169 or better 7500 x 628328. That means for the first image we have raw image data like 4.4Gb and for the other 8.8Gb. Of course this is just possible on a 64bit system.
Is there any plan to support huge raw images (64bit dng sdk)? If so when will you release it?
Best regards,
Marius

For #1, if you look at the image in Bridge you can note the dimensions and resolution...you would then need to put that same resolution in the ACR resolution field.
For #2, no...as you note the ACR Preference controls whether or not Camera Raw will be used to open the image. You can use the Shift key when double clicking in Bridge to open the image directly into Photoshop and bypass the ACR dlog, but Camera Raw will still be used if it's set to be used in the Preferences...
You'll need to keep your image resizing just in Photoshop because Camera Raw is not designed to do that sort of resize/resampling...it's designed first and foremost as a raw processor and later added the ability to open and process camera JPEGs and TIFFs. Putting those kind of controls into Camera Raw wouldn't make sense since the end result of an image opened into Camera Raw is supposed to be an image processed and opened into Photoshop. So, what you are wishing for is really outside of the scope of the development design...sorry.

Confused about editing RAW images on iPad

I just got a new 3rd generation iPad. I got it primarily to store, view, and edit RAW images captured by my Canon DLSR.
My camera takes 12 megapixel images. I am able to download them from the camera to the iPad using the Apple Camera Connection Kit. I can later move them from the iPad to my Mac. Everything flows through at the full resolution. This is all good.
My problems occur when I try to edit the images on my iPad. I have tried both Snapseed and Photogene. Both of these editors save the modified images at 3 megapixels. When I Google the exact dimensions of the saved files, I see they correspond to the size of the embedded JPEG preview stored in my Canon RAW files. So it looks like these editors are reading the embedded preview, and not the full RAW data. I do have Location Services enabled for the iPad and for these apps.
Is there an iPad image editor that will read RAW image data at full resolution? Maybe Filterstorm? Or do I need to use a RAW converter like PaRAWnah?
Thanks for the help!

Thanks for the comments. I do use LR and PS at home, and I do most of my editing there. But since I don't have a laptop, I was hoping to be able to occassionally process a raw image on my iPad when away from home, in order to extract details from highlights or shadows that did not expose well on the jpeg preview.
Since I originally posted this question, I did purchase PiRawNah just to see what it was like to use. You can see my thoughts on it here: http://forums.dpreview.com/forums/read.asp?forum=1046&message=41066455
Thanks again for the help!

Sony Image Data Converter no longer opens RAW files

After upgrading to Snow Leopard Sony Image Data Converter (ver 3.1) cannot open my RAW files. It sees the files but claims they are 0x0 pixels in size. It worked fine with Leopard 10.5.8.

Image Data Converter v2.2.02 also fails to open any files but was OK in 10.5.8. Image Data Lightbox v1.0.02 does run OK, opens a directory of files fine, and converts them. The app crashes on exit every time however!
Adobe Camera RAW and Adobe Elements v6 all work perfectly well. But I have never been able to see ARW images in Adobe Bridge!

How to change data format from [IMAQ create -- output -- New Image ] to [Unflatten Pixmap VI -- input -- image data]

hi gays,
i have two program,
the first one use {IMAQ create} to get a image from USB webcam,
the second one is picture data process which use [Unflatten Pixmap VI] to get a image data from a BMP file.
Now I want to combine this two program, but data format don't match between the output of {IMAQ create} and the input of [Unflatten Pixmap VI].
My LabVIEW version is 2009
What can i do??

Do you have VDM? Did you try "Image to array"?

Need help with EXIF date on raw images

I have just over 100 images (taken by 2nd shooter) that have the wrong EXIF date (JPEG and raw). They were taken with a 2nd camera that was off by +15hrs 57min.
There are many programs that will easily edit the EXIF date/time on the JPEGs, but they don't work with the raw images.
I've read that Lightroom can compensate for incorrect dates upon import, but after searching, I can't find any information on how to do it. Can someone please help?

I got EXIFTool working and solved my problem down to the exact second.
I was able to sync the times to within one second, based on one one particular event. One shot, taken with camera 1 was right before a handshake, while both people were extending hands, the other shot, with camera 2 (wrong EXIF date) was the actual handshake. I used this information to determine that camera 2 was 15hours 57minutes 18seconds fast.
Using EXIFTool GUI, I modified the date/time shift to decrement 15hours 57minutes 18seconds for all images from the second camera (both raw and JPEG). After this was complete, I checked the times, and the two frames (before and during the handshake) were only one second apart, and in correct sequence.
I imported the images from both cameras into Lightroom and had it rename the images based on time down to the second (YYYYMMDDHHMMSS-filename).
Now everything is great!

Output jpeg looks different than edited RAW image

I just got CS6 and have been working on some new images in RAW. Once I finished the editing I wanted to do in RAW, I saved the image as a jpeg, then clicked "open image" at the bottom of the RAW window. The image that came up in Photoshop looked nothing like my edited RAW image. It's as if none of the edits ever occurred. I've looked on the internet and tried figuring it out on my own. I'm at a loss and would appreciate the help.

Noel - first of all, thanks much for taking the time to respond to my question. You helped me realize (and I should have realized this last night) that my question and problem statement lacked a lot of detail. I'm new to Photoshop, but I've learned a good lesson. Here's some more details: I use a Nikon D700, WIndows XP OS, and CS6. After taking the images from my memory card directly into Bridge, I can see that the images look "good", meaning they match what I was seeing on my camera display. The metadata for my photo of interest states that the color profile is RGB, and I assume this is sRGB? I open the .nef file directly into CS6 RAW. Once again the image in RAW looks just like it did in Bridge and on my camera display. I like how it looks in general, but I make the manipulations I want in RAW (removing blemishes, softening skin, etc). Prior to saving the manipulated image, I click on the Workflow Options link below the image and choose 8-bit, sRGB, then save it as a .jpeg. Photoshop's color space has also previously been set to sRGB, so the two match. If I open the image from RAW directly into Photoshop or open the newly created .jpeg from Bridge into Photoshop, the image no longer looks like what I saw in RAW. The image looks sort of hazy, the black background that was completely black in the RAW image is now visible in the Photoshop image, and the model's skin, which looked nice and smooth in RAW, now looks pixelated.
You suggestions about color management make sense, and I bet I'm still making some sort of mistake in that regard. Any ideas?

Automatically export to JPEG from RAW images

RAW images are preferred form of shooting for many photographers. And, Lightroom is great at managing and developing these images. However, we increasingly use/view these images outside Lightroom and away from the PC where we do most of the development. For example, I use a DLNA server which shows off my entire image collection to big screen television (which can act as a DLNA client). The same DLNA server is used to send images to our smartphones (my wife loves to show all kid pictures anywhere she - without having to carry the pictures on the phone).
Most other applications that use these images, do not work on RAW images and JPEG images must be exported manually from Lightroom. This becomes increasingly difficult to manage and keep track of while developing RAW images. How many RAW images need to be exported? How many images did I touch since the last time I exported them?
Currently, I am using the following process to manage this:
1. I created a smartlist which contains images that are edited after "a particular date".
2. I select all images in this smartlist, and use Lightroom3's export function to export them all as JPEG, to the same folder as original.
3. Once the export is completed, I modify the smartlist to change the "particular date" to today's date.
I plan to repeat this procedure every so often (once a week or so).
It would be great if Lightroom had a feature such that it always keeps "JPEGs exported" for all RAW images (with the latest development settings of course). This could be a process that could occur in the background or at a user-specified time/event (e.g. when one closes Lightroom). User should be able to specify where the exported JPEG images should be put to and with what name (I prefer in the same folder as RAW but other users may have other preferences). User should be able to select if this is only done for RAW images or also for JPEG and other formats (in which case, should the exported image override the original or not). The exported images should be (optionally) automatically included in the Lightroom catalogue and stacked with the original RAW image.
Mainly, the entire process should be completely transparent to the user. A collection of JPEG images - corresponding to the latest development settings for the RAW images - should be always available.

I've heard many others raising the issue of an auto-jpeg feature - kinda like auto-write xmp, except auto-write jpeg.
I agree this would be nice, obviously some sort of "stability" check would be needed so it isnt constantly writing jpegs as you edit. Lightroom employs a form of this already for the xmp - meaning it doesn't update xmp every brush stroke, but accumulates several strokes before updating, so its more efficient...
If you could define multiple jpegs to keep - with the raws, or a separate tree - even better. That would obsolete all the tree output plugins and publishers.
The publishing feature was intended to fill this need (albeit manual only), but it suffers from the inability to publish to original directory, and/or an external tree.
I'd like to see a manual mode too, that accompanies a new "Done for now" function - so when you say "Done for now", it saves xmp, jpeg(s), snapshot, and optionally locks the file so unapproved changes can no longer happen to it. Then if you could define multiple "done for now" presets that include initiating publish service and exports, then the work-flow becomes: 1.import, 2.edit, 3.done for now - and thats it (maybe repeat 2 + 3 in the future). i.e. no more manually initiating the exports, publish services, snapshots, saving of xmp, ..., and whatever else you do when you're done.
In the mean time, I may make some of this part of an up-n-coming "Sidekick" app + plugin combo when I get to it.
Presently, I dont use publishing services, and I have ExportManager to consolidate exports (which includes TreeSync), so my workflow is: 1.import, 2.edit, 3.done for now (save xmp+snapshot, and lock via ChangeManager), 4. initiate consolidated exports...

If xmp creation date precedes raw file date Bridge/ACR does not recognize

I decided to start a new thread with this revelation from a prior discussion, because of its importance.
I have several iPad apps that apply metadata to raw images captured in the field using the camera connection kit. These apps have various export mechanisms, with a typical capability to bundle up raw images from the Photos app space with xmp files from the metadata editor app's space, and deliver them via ftp or however. I have seen failures where the creation date of the image file was made equal to the creation date of the xmp, and subsequent to export Bridge would not recognize the xmp file as valid edits to the raw file, even though they both had the same file name ahead of the extension. Up to now I never understood the cause of the failure. Opening the xmp file in a text editor and saving it out with a later creation date "fixed" the problem.
Adobe either needs to change this behavior (IMO the right solution, forget about checking creation dates) or at least publish the dependency. I believe there are a lot of programmers out there that had no idea that the creation date could invalidate the coupling between the raw file and the xmp file.

Ok, made some tests.
First: there is nothing interesting in /sys/class/drm. Only one file called version... which, as you might guess, contains the version info for DRM.
Secondly: tested this Phantom Output thing. Used LVDS-1, LVDS-0, LVDS... nothing.
I even tried to add i915 and intel_agp modules to the initramfs... nothing changed.
However, I looked a bit more into dmesg and found another interesting thing:
[ 2.038447] Linux agpgart interface v0.103
[ 2.041261] input: Video Bus as /devices/LNXSYSTM:00/device:00/PNP0A08:00/LNXVIDEO:01/input/input8

So it seems there is a problem with the AGP module not correctly detecting the card in the first place
Edit: also tested it with the internal screen connected, still the same problem.
