Converting to Tiff

I shoot with a range of cameras and almost always in RAW, making my conversions in aperture.
Is there a good enough reason to convert to TIFF afterwards? Right now the files sit on my HDD in RAW and Aperture converts them to jpeg for emailing, web site production, printing etc.
If TIFF is a good way to go how would I convert the file and have it over write the original RAW file so I dont have ot double up space on the HDD?

It doesn't work that way, and I see no reason to convert to replace any Masters to be TIFF. When Aperture creates a new version (and actually a new Master) for sending to an external editor it is TIFF or PSD, as you preference. Obviously you can Export as TIFF anytime you need to share that format with another party, or another app.
There is nothing to be gained from having the master as a TIFF, and from a possible future editing need, a lot to lose.

How open images from other programs & convert to tiff?

I am new to digital photography. I usually take 2 to 3 MB images with my Canon Rebel XT and use iPhoto as my basic program to organize images, create albums, and do very basic editing. I'm running on a G4 Powerbook with OS10.3. I expect to upgrade to iPhoto6 soon. I also use Canon's Image Browser (because it does a better job of compression for emailing that my present iPhoto) and an abbreviated version of ArcSoft PhotoStudio which came bundled with my Canon and has editing tools similar to Adobe Photoshop Elements.
So far I usually use iPhoto's "Preferences/Open in Other" command when I want to open one or more selected images in one of the other programs. I have not found any easy way to locate an image while working in ImageBrowser or PhotoStudio, because iPhoto assigns folder numbers by date, so I'd have to know in which of many numbered folders to look. Placing images into iPhoto albums does not help because while the album names appear in these program's tree view they appear unable to link to them. Canon refuses to answer questions relating to iPhoto and referred me to ArcSoft for any questions about PhotoStudio. ArcSoft says they provide no support for programs bundled with hardware. Typical. What I'd like to know is:
1. Is there any easy way to locate iPhoto images while I'm in one of these other programs?
2. Is there any way to copy an entire album from iPhoto to one of these other programs?
3. I've attended two different digital photo classes in which instructors felt it desirable to convert jpegs to tiffs. One felt it was necessary to reduce the loss of pixels during editing, and the other does it for any image he plans to print, claiming it improves print quality. They recommended getting a special conversion program. Based on responses here to the topic: "Want to save jpeg file as tiff before making edits to photos", others feel that for most amateurs like me this is a minor issue, especially with iPhoto. Testing this I have found, as Kevin Wolfe1 says Feb 12, that compression of a jpeg appears to occur primarily on the first edit and does not sognificantly degrade the image. The programs I mention above appear able to save an edited jpeg as a tiff if desired, but I've noticed also that iPhoto's Export command includes the option to export a jpeg (to desktop or another folder) as a tiff. When I tried this, it did create a file identified as .tif, and I can drag that file back into the iPhoto Library where it remains named as a .tif, and according to iPhoto, this file contains about 5 times the MBs the original jpeg had. What I'm curious to know is, is that a true tiff file or is iPhoto kidding me?
Powerbook G4 Mac OS X (10.3.9)

Typical. What I'd like to know is:
1. Is there any easy way to locate iPhoto images
while I'm in one of these other programs?
In iPhoto 06 you have the option to NOT move imported image file in to the iPhoto library. So they images stay in the place where you put them. With this option the iPhoto library only contains "pointers".
2. Is there any way to copy an entire album from
iPhoto to one of these other programs?
Can't you open an album, select all the images then then use "export"
3. I've attended two different digital photo classes
in which instructors felt it desirable to convert
jpegs to tiffs.
If you are worried about this then you should be shooting RAW format. In your case the camera is doing the JPG conversion and the "damage" is unrecoverable.
iPhoto 6 and Tigeer (10.4.x) has a little bit better supportfor raw format images i yu are worried about something that makes such a small difference then you should be woried about the stuf that makes a large difference first.
You might want to concider this workflow:
1) use Canon software to download files from camera
2) use Canon software to convert to TIFF
3) Import TIFF to iPhoto (using option to NOT consolidate library
4) specify arcedit, PS or Gimp as your external editor
Others might want to lt iPhoto do the import and raw conversion but you said you wanted thr photos to be stored outside of iPhoto's library system you you can find them with out having to do an export.

How do I Convert a Tiff image to a jpeg without being FORCED to 8-bit Color?

I am an Artist. I have High quality TIFF images. When I convert the tiffs to jpeg it forces me into 8-bit color automatically. (Forget about 32bit - it will not allow me to jpeg that at all) The only way I can get back to 16bit color is to use the already SMAshed file and bring it up to 16bit. THIS makes NO sense. Once the jpeg is smashed, HOw in the world is it supposed to convert up again. ?? Then even though it says you converted the file to 16 -bit , the metadata refers still to the file as 8-bit.
On top of all of that confusion, One picture, for example, when supposedly converted to 16bit, gets much BRighter then even the original Tiff image. It looks good on one hand and over exposed on the other. I assume that is photoshop throwing in fake resolution, am I right?
Am I wasting my time with this imaginary 16bit conversion?
Is there ANY way to take that original Tiff image and convert it to 16bit jpeg without the Default 8bit? I have been trying all kinds of things. I even have asked my web guy. My web guy says that 8-bit is unexceptable for printing, even for web.
Could this have anything to do with my computer and scanner?
I have the iMAC OS X 10.8.3 (3.2 GHz) 8 GB memory.
And I also have an Epson Expression 10000XL graphic arts scanner capable of scanniing at 48bit color.
This color stuff Really matters! It MATTERS! I HAve FINE art files. I am already losing so much quality with the jpeg conversion. (which I am required to do for SmugMug, in addition to compressing all my files to 50mb or Under)
Anyone who knows anything that could help me would be much appreciated.
Aloha,

First of all jpeg is 8 bit only there is no way to save as a 16 or 32 bit jpg, just does not exist. Secondly people print in 8 bit all the time and most if not all web graphics are in 8 bit as that is the only way to view it as there is no 16 bit or 32 bit monitors to view it. All but a few pro monitors are 8 bit monitors.
If you care about the color gamut and want the full range of color that 16 and 32 bit provide, then why jpg? Jpg by its own nature throws out color just to compress, thats why it is popular on the web, because of its small file size not its quality. If you need 16 or 32 bit for anything it must be in a format that supports that color depth.
That being said a jpg image at 8 bit will display 16+ million colors, 256 shades of red, 256 shades of green and 256 shades of blue.
Now here is where I think your bit information is off. a jpg image is a 24 bit image that will produce 8 bits of red, 8 bits of green and 8 bits of blue.
The 8, 16 and 32 are per channel not total color information.
If the overall image was 8 bits, the image would be gayscale.

Read 16 bit binary image into LabVIEW, convert to TIFF and display

Hello,
I have what is probably a simple problem - I have RAW images (1536 x 1944) saved in binary files consisting of unsigned 16 bit integers that I need to read into LabVIEW and be able to view on the front panel (so presumably convert to TIFF or something like that).
This is not information that was written using LabVIEW - it was actually written using the fwrite command in C++ if that is any help, and has no header information.
I found this example VI:
http://forums.ni.com/t5/LabVIEW/read-the-raw-image-file/td-p/505871/page/2
The picture of the final VI solution that is posted at that link - it looked promising, but the flatten pixmap function appears to only take in 8 or 24 bit inputs, not 16 bit inputs, and I was unsure it if was possible to configure it for 16. Is it possible to use this same structure to read in my binary files as well? If so, what changes need to be made? Otherwise do I need a different function? I am very new to image processing in LabVIEW.
Thank You.

Hello,
The flatten pixmap function does not appear to be able to take in 16 bit inputs and I cannot find a function that flattens a 16 bit pixmap. Is there any way you can convert your binary file into that of 8 or 24 bits?
Also, I don't know if this other forum thread may help or give context to the subject.

Converting a .tiff file to PDF

I can not seem to convert a .tiff file to PDF, it keeps giving me a error. What can I do? I have Windows 7

Oh dear! Unfortunately, it sounds like the problem is specific to the file in question, which means that we wouldn't be able to reproduce the error you've been seeing with another file. Why don't you try creating a comparable .tif file and see if you can upload it? I would be very surprised if you received the same error message, so the goal here would just be to isolate the problem as existing only in the other file. If it's not too much trouble, give it a shot.
All that being said, if we can't test the file ourselves, it'll be tough to find a workaround for you. Sometimes certain files contain a piece that our servers have trouble with, so we like to be able to examine the files that prove difficult, and often wrestle them into compliance. I'm sorry not to be able to offer more specific instructions, Sharmaine! Let me know how your experimenting goes.
Best,

Converting uncompressed Tiff to Tif (zip)

Slide scans from my Nikon scanner come out as uncompressed tiff. I want to convert them, in situ, to Tiff (zip) compression as that results in the smallest file size. I've tried Actions, Droplets, Bridge – there appears to be no way to convert without encurring the Save As dialog boxes.
Is it possible, either within PS or elsewhere, to select (or open in PS) an uncompressed tiff and have the file replaced by a Tiff (zip)?

Thanks for the responses. I tried Image Processor Pro but it has the limitation of not being able to set layer compression. When I ran it on PSD and Tiff (Zip, Zip) files, it caused file sizes to increase in both cases.
I have a workaround which I am now using, but it would be better if I could simply select the files in a folder, drag them to a processor which causes all selected files to be saved as Tiff (Zip image compression, Zip layer compression). If the original is Tiff, the processor overwrites the original Tiff file without warning.
Before I ask in the Script forum, can such a script be written?
Below, for my future reference, are my notes re the workaround.
WORKAROUND
Because of problems when scanning with ICE (dust removal), two scans are necessary for the best scan results: with and without ICE. The two scans are then layered in the one PS document, aligned, ICE-corrected using a layer mask, and then flattened to save space (or left as is).
So, for each slide out of the scanner I end up with two Tiff files, 60 MB each, which I archive (after compression). Then I do the ICE-correction which results in a layered Tiff (Zip, Zip) file, 100 MB, also archived. For some slides, the archived version is flattened (30 MB) to save space. The problem is: the conversion to Tiff (Zip, Zip) carries a large time penalty (see File Sizes below), causing delays.
My solution is:
ICE-correct the two scans of a slide and save as PSD, giving a 120 MB file with a negligible save time. Size of the three files at this point is 60 + 60 + 120 = 180 MB.
When finished a batch of slides, copy the files to a temporary folder.
Batch process the folder in Photoshop, using a convert to Tiff (Zip, Zip) action, with the Destination option set to Save and Close, and with Override Actions “Save As” Commands” ticked. Processing time will be about 30 seconds per slide. Photoshop is tied up during this time.
When processing is finished, there will be four files per slide: ICE, No ICE, ICE-corrected (PSD), ICE-corrected (Tiff:Zip:Zip). Call the number of slides, N.
Sort the folder by “Kind”, and delete all the PSD files which will be in a bunch. As a double-check before deleting, there should be ¼N files.
Sort the folder by “Size”. The newly created ICE and No ICE (Tiff:Zip) files will appear at the top, each about 30 MB. Archive these files. There should be ½N files.
The remaining files in the temporary folder, in Tiff (Zip, Zip) format, 100 MB each, can be returned to the original folder.
Slides of special historic interest (such as Lake Pedder) should be left as two layers to protect their integrity. All others can be ICE-corrected and flattened to give 30 MB files (instead of 100 MB), ready for further processing.
At this point, total archived size of a scanned slide is either 90 MB (30 + 30 + 30) or 160 MB (30 + 30 + 100).
File Sizes
Original scanned files (single layer)
Tiff (uncompressed from scanner, single layer) = 62 MB
Saved as Tiff (Zip) = 30 MB, save time of 8 seconds
After ICE-correction (two layers)
Tiff (Zip, Zip) = 100 MB , save time of 18 secs
Tiff (Zip, RLE) = 150 MB, save time of 12 secs
PSD = 120 MB, save time of 4 secs
The space saved by using Tiff (Zip, Zip) carries the cost of a large increase in save time, from 4 to 18 seconds, even longer if the save occurs while scanning the next slide.

Comment convertir un .tiff en un .BMP?

Bonjour à tous
Comment convertir un .tiff en .bmp ???
je sais ouvrir un .tiff avec Imaq mais pour le reste je sèche..

You should be able to use the IMAQ Read File VI to read the file in, then use the Write BMP File VI to write the file. A similar approach is used in this example: Convert PNG or JPG to BMP file

"Adjust Date and Time..." will convert your TIFFs to JPGs!!!

I wanted to let everyone know of a serious bug that I've been discussing in the following thread: [http://discussions.apple.com/thread.jspa?threadID=1315705&tstart=0].
Here's the bug. If you use the "Adjust Date and Time..." function on a TIFF file, and have iPhoto modify the original file, iPhoto will make the time adjustment, but it will *save a JPEG over your original TIFF, with the original .TIF name!!!*
Big nasty bug. After you do this function, you have lost all that lossless TIFF data since your pictures was overwritten by a lossy JPG!
nathan

nathan:
What type of edit were you making. Have been trying to duplicate that and cannot. I've changed the date and selected the original file to be changed also. Then I edited the file by cropping, changing the exposure and shadows and saving. Both versions are still tiff files.
Now these are tiff files that I converted over from jpgs with Photoshop as my camera doesn't take tiffs. Don't know if that will make any difference.
TIP: For insurance against the iPhoto database corruption that many users have experienced I recommend making a backup copy of the Library6.iPhoto database file and keep it current. If problems crop up where iPhoto suddenly can't see any photos or thinks there are no photos in the library, replacing the working Library6.iPhoto file with the backup will often get the library back. By keeping it current I mean backup after each import and/or any serious editing or work on books, slideshows, calendars, cards, etc. That insures that if a problem pops up and you do need to replace the database file, you'll retain all those efforts. It doesn't take long to make the backup and it's good insurance.
I've created an Automator workflow application (requires Tiger), iPhoto dB File Backup, that will copy the selected Library6.iPhoto file from your iPhoto Library folder to the Pictures folder, replacing any previous version of it. It's compatible with iPhoto 08 libraries and Leopard. iPhoto does not have to be closed to run the application, just idle. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

D300 RAW files converted to TIFF Anomally

Ok....heres the thing! I recently spent 2 months in Argentina working on shootshorses.com. I used a Nikon D300 RAW (12mb) and downloaded everything (70 gig) to an 80 gig ipod. Aperture at this point could not read the nikon nef file so viewed them in nikon view nx, picked 50 or so I wanted, converted to 16 bit tiff on desktop and imported to Aperture. (now 77mb files)
When upgrade for aperture 2 came out, installed and attached ipod and imported all the work. Started working on some of the same images in the new projects in order to uplaod more to web site. wanted to lift and stamp changes from tiff files and apply to freshly imported raw duplicate files then delete much larger tiff files. Point...the identical stamped changes make a completely different image.
Checked the new raw file against the previous tiff file with no adjustments on either, on screen (apple 30 inch) and the tiff files blow the raw masters away for depth and sharpness. do not understand why as they are both the original Raw file from the ipod.....Question is, why is this? Suddenly the raw files really look digital and the tiff files have a depth that approach the work done on the kodak DCS pro.... and that is a bench mark!
If anyone has any explanations it would be great. Many thanks
A perplexed David Sinclair.

AHHH... . amazed there is such a notable difference.... simple really. Only problem ,natural I suppose, Capture nx being same manufacturer, but makes me ask what else might be missed in the way of picture quality with Aperture. Many thanks for your answer

Why DNG files are bigger when converting from TIFF?

When I shoot in RAW, my normal workflow is to convert all images to DNG and start editing in Lightroom. But as you know, there are some photos that need extra editing in pixel based software such as Photoshop.
When I right-click a DNG in Lightroom and chose "Edit In... » Edit in Adobe Photoshop", the photo will be opened in Photoshop as an 8-bit TIFF file for editing. For demonstration of my issue, let's assume I don't do any changes and just save the file as it is. A new TIFF file will be created next to the source DNG with "-Edit" in it's name.
Back into Lightroom, both files are almost the same, one is DNG, the other in 8-bit TIFF. From this point (assuming I did change something in Photoshop, otherwise what would be the point in opening it there) I should do my further editing in Lightroom in the TIFF and not the DNG one. Let's say I'm done with the work and export the final edited TIFF file back into a DNG (I like this format and I like to keep all metadata changes so I can easily revert back to the original). I've also exported the original DNG file for comparison.
And now I realize the following:
DNG to DNG » ~7Mb (basically the same as the original DNG)
TIFF to DNG » ~15Mb
Why such a big difference?
I didn't do any editing either in the original DNG or the Photoshop converted TIFF. Any techincal reason for this that I'm not aware or am I doing something wrong?

I did a little bit of research and:
1) The embedded previews are always JPEG files (medim or full size, doesn't matter). But now that I think about it, I don't think you were talking about the previews when you mentioned the TIFF being embedded.
2) I did a quick EXIF lookup on 3 files exported to DNG: a) Original DNG b) 16-bit TIFF converted to DNG c) 8-bit converted to DNG. Here's the EXIF results:
a)
SubfileType                     : Full-resolution Image
ImageWidth                      : 3736
ImageHeight                     : 2772
BitsPerSample                   : 16
Compression                     : JPEG
PhotometricInterpretation       : Color Filter Array
SamplesPerPixel                 : 1
b)
SubfileType                     : Full-resolution Image
ImageWidth                      : 3648
ImageHeight                     : 2736
BitsPerSample                   : 16 16 16
Compression                     : JPEG
PhotometricInterpretation       : Linear Raw
SamplesPerPixel                 : 3
c)
SubfileType                     : Full-resolution Image
ImageWidth                      : 3648
ImageHeight                     : 2736
BitsPerSample                   : 8 8 8
Compression                     : JPEG
PhotometricInterpretation       : Linear Raw
SamplesPerPixel                 : 3
This probably means something like you said... The embedded files are different and some take more space than the others. The first one is 7.220Kb, the second one (16-bit TIFF) is 44.030Kb and the third one (8-bit TIFF) is 15.284Kb.
It makes sense I guess, but I still would love to hear a more technical explanation for it but it's obvious it has something to do on how the pixels are saved in the DNG file. The keyword is probably the PhotometricInterpretation.
