Seeing raw data in TIF file

Can I use Photoshop to open a TIF file and actually see the raw data (pixel data) inside the file?

BMP might be easier to parse into tabular data:

How does my application save the raw data to binary file?

Hi all,
At first, please look at my attachment. There is the part of my code (it is inside of a while loop) which saves a raw data from my firewire camera. I am thinking how does this saving process work? How does it save the data in each while loop's iteration time (pixels, rows and columns)? For example if I use 100x1000 8-bit image. There is also Set File Position.vi which makes next line after iteration (at least I think so?). It is important to know when I'm processing the data later with Matlab.
My second question:
If I set height = 100 and width = 1000 as parameters, image indicator from IMAQdx Grab's image out says that the image is "only" 1000x96 8-bit image. Where are "missing" 4 bits?

Hi again,
Here is my whole CameraSoftware. It is a part of the bigger measurement program.
I hope you can find the solution of "lost 4 bits"

I'm trying to import raw data from excel file to diadem, how can i do that, and also i want to know if i can put header for it or not?

i'm using diadem version 8.1, and my operating system is windows Me.
i'm also want to know if the diadem hae an "undo button" or not??

Hi,
To import EXCEL files you can open the device DATA and then go to the menu FILE->OPEN. In the following dialog you must set the FILE TYPE to Excel. If you open an Excel file with that settings the Excel-file-import-wizard will be launched. With the wizard you configure the parameters which should be imported (that includes header parameter too). Please refer to the NI-Web page to get the latest service pack "SP1d" for the Excel import filter (http://digital.ni.com/softlib.nsf/webcategories/85256410006C055586256BBB002C104B?opendocument&node=132070_US)
Yes, in DIAdem 8.1 we support undo for displacements in the device GRAPH. For DIAdem 9 we expand this functionality.
I hope this information will help you.

Exporting File Name to "Raw Data" Metadata

At one time I was able to export a file's original file name in the "Raw Data" area of the metadata. I seem to have lost that ability in LR 4. I find this useful when a client renames a file and then wants me to find the original. I would open the file in Photoshop (or even a word processor) and the original name would be in the Raw Data area in File Info.
When LR 4 imports the file the first time, it apparently still creates the xmp file with the file name at the end of <rdf:Description rdf:about="" field and it looks like: crs:RawFileName="_DSC6501.NEF">
At one time Lightroom exported that info. But now I seem to have lost that file name info, even with "Export All Metadata" selected.
This is how it would look in Photoshop's File Info:
<rdf:Description rdf:about=""
            xmlns:crs="http://ns.adobe.com/camera-raw-settings/1.0/">
         <crs:RawFileName>DSC_8466.NEF</crs:RawFileName>
         <crs:Version>6.7</crs:Version>
         <crs:ProcessVersion>5.7</crs:ProcessVersion>
Now it just says:
<rdf:Description rdf:about=""
            xmlns:crs="http://ns.adobe.com/camera-raw-settings/1.0/">
         <crs:Version>7.0</crs:Version>
         <crs:ProcessVersion>6.7</crs:ProcessVersion>
What am I missing?
Thanks!
Stan

Hi John, Thanks for your reply. I actually use Metadata Wrangler, but there is no "copy original file name into metadata" switch that I can see. And when you ask it to export all metadata, it actually doesn't.
After several hours of testing I've found the culprit. Lightroom does not export all the metadata if you save it to a JPEG file, even if you tell it to. Neither does Photoshop's "Save for Web" even if you tell it to save all metadata. Both lose the field with the original file name (see my first post above).
But if you export the file to Photoshop using the "CMD + E" command, Photoshop gets all the metadata. If you then "Save As" a JPEG, the original file name travels to the newly created JPEG file. It's there in the metadata. If you then do the same thing with "Save for Web" with "metadata" "all" you lose the file name field.
So since you are asking all these programs to "save all metadata" and they don't, I would consider that a bug.
Wouldn't you?

Is there a way to save Aperture RAW edits (previews) as .tif files?

In iPhoto Preferences/Advanced, it is possible to choose to save RAW edits as .tif files. The resulting files are then stored in the Previews folder inside the iPhoto Library. In Aperture, edits of RAW files are stored in the Previews folder as .jpg files. I am aware that I can export the edited versions as .tif files outside of the Aperture Library. Is there a way to do it inside the Aperture Library, just the way iPhoto does??

Probably collecting everything on an artboard into a new layer might give you the option to use a script to save layers to files.
But this is a feature request but no as of yet has suggested a way that this might work, at least I do not think so.

Lr Mobile 1.2.1 does not recognize .tif files added to iPhone 6 + iOS8 Camera Roll

I use an app called ProCamera 8 to save images taken with my iPhone 6 to uncompressed TIF files or TIF files with LZW compression. The problem is that Lr Mobile doesn't see any kind of TIF file in my iPhone camera roll at all. I've tried to:
Save the photo taken by PC8 directly to the camera roll
Save the photo taken by PC8 to it's own "Lightbox" folder, then export it to the camera roll.
Manually import the TIF files that appear in the iPhone's camera roll using Lr Mobile's Add From Camera Roll command. TIF files in the camera roll don't even appear in the list of photos!
None of the above methods will get a TIF file into a Lr Mobile collection.
If I repeat the process with JPG files, everything works as expected, and all 3 methods listed above will get the JPG images into LR Mobile.
I think this is a bug (and a serious one) because TIF files in Lr Desktop that are added to a collection that is synced with Lr Mobile appear Lr Mobile on my iPhone immediately. So I know that Lr Mobile supports the display and editing of TIF source files.
Until this is fixed, is there a workaround possible?
Thanks,
Jeff
EDIT: The native Photos app in iOS 8 displays all of the TIF files correctly.

The latest update to Lightroom Mobile now recognizes Tif files. Strangely, in the import window they show up with with a RAW label on them but, once imported, the metadata labels them as tiffs. This made me wonder if LR mobile also now supported actual RAW files. Alas, a quick test proved this to not be the case.
That said, this is pretty cool news for those who take pictures with their phone's camera. I too use a camera app that allows me to save images as tiff files. Now these files can be imported to LR Mobile and edited using the array of tools found there. I've always liked Lightroom's superior versions of tools like Clarity, Highlights, Shadows, Whites, and Darks but found them of little use on Jpgs, due to the smaller amount of data they contain. While Tiffs aren't quite as info packed as RAW files, they are a huge step better than jpgs.
One slight caveat which, depending on your outlook could be either a good or bad thing. When you save a tiff file from LRMobile it automatically converts the image to a jpg and reduces the image size to around 63% of the original image (the native size of a photo taken with my iPhone 6, 2448x3264, is reduced to 1536x2048). At first I was rather upset with this, as far as I can tell, unchangable automatic action. However, after thinking about it a while it occured to me, that for my use of LRMobile at least, it is not such a bad idea.
FIrst let me say that I do not see my iPhone or my iPad Air as optimal photo editing devices. For serious editing I'm going to use my computer hooked up to my calibrated 27" NEC monitor. However, for doing some quick fixes/adjustments on iPhone snapshots this makes complete sense. Most other mobile editing apps only support jpg as do most of the major social sharing sites on the web. A smaller sized image, and it's inherrent smaller file size, is also better for emailing, sharing on websites, etc especially if you are using cellular data to upload with. Admittedly I would have prefered the option to save as either a tiff of jpg and also the option to select the image size, but overall this "feature" is OK with me. As I said if your usage of LR Mobile differs from mine you could well be holding your head in your hands moaning by now.
While I'm still waiting for the ability to edit keywords and other metadata, the thing that would make LR Mobile an essential app for me, this addition of tiff support has actually gotten it out of my "Archive" folder and back in to use.
PS: one thing that has always worked well is the sync between devices (internet required) so it is geeat for getting your phone photos onto the your iPad.

ACR 4.4.1 does not open TIF file from bridge (CS3)

Hi,
I have the preferences in CS3-Bridge and ACR set to open JPG & TIF files in ACR and not CS3 but when I click on a TIF file in bridge it opens in PS CS3 instead. These TIF files were generated by a GUI interface for ENFUSE which is an algorythm that combines bracketed RAW or JPG exposures for expanded dynamic range... it works very well ad outputs to TIF... but I can't seem to open these TIFs in ACR. Isn't a TIF a TIF?
Is there a way to force ACR to open these?

There are many varieties of TIF files (including b/w fax images).
I have no idea if this will work, but you could try opening one of the files in Photoshop, saving as a TIF from Photoshop, and then see if that new TIF file will open in ACR. At least it should let you know of opening of TIF/JPG files in Camera Raw is working correctly.

Scanner tif files opening in Camera Raw

With CS3 installed, some of my scanner generated tif files from an Imacon
scanner are now opening in Camera Raw window of PS CS3.
Windows XP SP2
Windows file type association set to Photoshop CS3 for tif files.
Using Windows explorer, choosing to open the tif file in CS2 works fine,
file opens directly in PS CS2.
Using Windows explorer, choosing to open in CS3 opens the same file in ACR
and then in PS CS3.
David

David,
Im glad you opened this thread. Im having the opposite problem. I have a scanner TIF image (sent to me by someone else) that we want to open in ACR. He had already opened it in CS3 ACR4 before sending it. I just installed CS3 today.
I tested this file at a local camera store yesterday and it behaved as I expected. That is, I could open in PS or ACR as desired via the fly-out menus. But after installing CS3 on my own machine, I could not (Camera Raw options grayed out). I checked with another local user. Same problems.
Then after reading this thread and purging the folder cache things started working, as I wanted them at least. I would assume the folder cache came from CS2.
So my question how does this really work? I will want to selectively use it in the future. If I look at the metadata for a NEF image is see camera data (exif) and camera raw data as expected. But I see neither for this image. And I would not expect a scanner to be embedding raw settings unless it truly supports a raw format.
When I tweak a few ACR settings and click done, the file is updated but no XMP sidecar file is created. I can now see camera raw settings in the metadata panels. This is not what I would expect. And I cant find any camera raw settings in the Photoshop file info panels for either file.
So, how do I control this behavior for future TIF images? Will I have to purge folder cache if it was created with CS2?
Cheers, Rags :-)

How to delete the raw-data out of the meta data (file information)

Hi guys,
I am definetely going crazy: since half an hour I can´t find a solution than copy (image) paste and save as a virgin jpeg: I`ve just converted some 0,5 GB tif files which I elaborated heavily in ACR and the 550 by 367 PIXEL JPEG @ quality 9 has 1,1 MB. As all your moves are saved in the raw-data (last field inthe fileinformation) there´s quite a bit on the file, also on 3 by 2 Pixel (!) "big" derivates. It seem´s there´s no intellegent way to discard this information. If you know, please let me know!
Thanks, Sebastian

You could try the following code to remove all the metadata, run it from within ExtendScript Toolkit and select the files in Bridge.
#target bridge
removeXMPData();
function removeXMPData(){
if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
var sels = app.document.selections;
for (var a in sels){
var thumb = new Thumbnail(app.document.selections[a]);
var md = thumb.synchronousMetadata;
var xmp = new XMPMeta(md.serialize());
        try{
        XMPUtils.removeProperties(xmp, "", "", XMPConst.REMOVE_ALL_PROPERTIES);
        var updatedPacket = xmp.serialize(XMPConst.SERIALIZE_OMIT_PACKET_WRAPPER | XMPConst.SERIALIZE_USE_COMPACT_FORMAT);
        thumb.metadata = new Metadata(updatedPacket);
        }catch(e){alert(e);}

Import Movie-type Raw Data File

Hi Folks - this one should be an easy one but having problems. Been given a single file that is a series of 10 frames with 256 rows x 320 cols for each frame. Data representation is I16 or U16 (I have tried both [also tried I8/U8 just in case]). I am using the following simple piece of code to try to open but getting error 71 (File datalog conflict). Any thoughts - need a second set of tired eyes to look at this. The raw data file I have named .doc just because the forum post would not accept .raw extension which is what you can rename the raw data file to.

My impression when I got the file was that all of the frames were first stored in an array prior to just writing to a file. (The acquisition was done with a non-LabVIEW controlled instrument). Then I thought maybe each frame acquired was then stored, followed by next frame acquisition and storage, etc. Now, my next approach is the byte (binary file) reading using options of I16, U16, big-endian, little-endian as options. For example, here is the code to do one variation and this seems to be getting me closer (I am not in touch with data acquirer to see what the actual frames should look like). With this code, I am definitely opening the data frames and displaying them.

What VI can read raw data from a TDMS file with scaling information entered?

I would like to use scaling with my TDMS files so that the end user will
only see engineering unit values, however, within my Labview application, I
want to retrieve the raw data. Is there a way to read the raw data using
one of the Vi's in Labview?

The scaling information in a TDMS file is stored as properties of the channel. One trick (that I haven't mastered yet) is you can change the properties of the TDMS file (set properties) and set all the scales to have a offset of 0 and a scale of 1. This will apply a scale that has the engineering units be the same as the raw values. Then you can read the data like normal and you'll get the raw values.
There are several issues to be aware of, the first is changing the scale and forgetting to change it back, or some how modifying the data to be incorrect units and not knowing it. For this reason I'd recommend making a copy of the TDMS file to a temporary location to make the modifications to the properties, read it, then delete the temporary TDMS file when you are done.
This is the only way I know of to get the raw readings from a scaled TDMS channel.

Parsing raw DAT files from WVC210 IP cam

Hi,
Is there any information available about the raw DAT file format that cisco uses for the WvC210 IP camera's?
A surveillence system based on 2 WvC210 IP camera's was vandalised and we could salvage only the DAT files, the rest is trashed.
I've loaded the software onto a new system and put the DAT files in the correct location but nothing works on these files.
I can see structure in the raw data, so there is something there.
The validate tools and the DBTools don't have any effect so maybe the files are mangled.
But as a programmer I could parse the files and possibly pad stuff to get it working again.
It's really important we do a full effort to retrieve some evidence, any help is appreciated.
I've read most posts and I relalise the product is EOL, but all I need is the file structure, any tech docs available?
Regards,
Shaun

Hi Alan,
We have more .DAT files but no .rcd or other files.
Here is the full file list, showing bytes and filenames.
These are all the files that were recovered from the vandalised harddrive.
But I'll double check this just to be sure.
I'm guessing the naming convention is:
C00000/1 (camera number)
S00A ??
20120215 (year-month-day)
151302 (hr-min-sec)

Is it wise to keep the Nikon camera files "DSC's" after downloading them and converting to DNG files via Adobe converter for lightroom use. In other words do the DNG files have all the raw data I would ever need in processing or should I save the camera's DSC files?

DNG files do not contain some metadata supplied by the camera, which can be used by the manufacturer's software. Thus, if you don't keep the original Raw photo, you will lose this information.
If your 1000% sure you're never going to use the manufacturer's software, then this isn't a problem. But who can be sure what software you will be using 10 years from now?

Problem in Compresses file.Not able to see the data in file

Hi All,
I am downloading file into application server.
Using:
OPEN DATASET file FOR OUTPUT FILTER 'compress'.
OR
DATA: l_command(100) type c.
   CONCATENATE 'compress ' p_file INTO lw_command SEPARATED BY space.
    ENDIF.
    CALL 'SYSTEM' ID 'COMMAND' FIELD lw_command.
When I see the file content it contains junk characters.
If I want to see the data Do I need to uncompress the file.
con't we see the data without uncompressing the file?.
Regards,
vinod

Hi,
Uncompress is required to read the content of an Compressed file.
OPEN DATASET DSN FOR OUTPUT FILTER 'compress'.
OPEN DATASET DSN FOR INPUT FILTER 'uncompress'.
The first OPEN statement opens the file so that the displayed data can be read into it in compressed form.
The second OPEN statement opens the file so that the data is decompressed when it is read from the file.
