TIFF File Size

Sometimes when I save a JPEG as a TIFF, it creates a file that shows a file size of say 3MB, but sometimes a JPEG of similar dimensions and resolution will come out as a TIFF that is in the range of 20-30MB. What might be making that difference in the resulting files size?

PDF to TIFF conversion Tiff File Size problem after conversion

Hi,
I am able to convert the PDF file into multi page TIFF file using the below method. But i am getting a size of 1.3 mb for each page of TIFF file (noofpagesX 1.3 mb). it's huge size right? So Could any one please help me out how to decrease the size of the TIFF file? It's an urgent for me. help me out.....
public static byte[] PDF2TIFF(byte[] bai, String imageType) {
byte[] out = null;
try {
PdfDecoder decoder = new PdfDecoder();
decoder.openPdfArray(bai);
decoder.setSize(100, 100);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
BufferedImage image[] = new BufferedImage[decoder.getPageCount()];
TIFFEncodeParam param = new TIFFEncodeParam();
param.setCompression(TIFFEncodeParam.COMPRESSION_PACKBITS);
param.setLittleEndian(true);
param.setWriteTiled(false);
if (decoder.isFileViewable()) {
for (int i = 0; i < decoder.getPageCount(); i++) {
int pageNumber = i + 1;
BufferedImage imageTemp = decoder.getPageAsImage(pageNumber);
System.out.println("Page Number."+pageNumber);
image[i] = imageTemp;
ImageEncoder encoder = com.sun.media.jai.codec.ImageCodec.createImageEncoder("tiff", baos, param);
Vector vector = new Vector();
for (int i = 1; i < image.length; i++) {
vector.add(image);
param.setExtraImages(vector.iterator());
encoder.encode(image[0]);
baos.flush();
baos.close();
decoder.closePdfFile();
out = baos.toByteArray();
catch (Exception e)
e.printStackTrace();
return out;
Thanks

For the Batch Sequence that "asks" --
Something to try.
Open the Batch Sequence dialog.
Select the appropriate Batch Sequence.
Click the Edit button.
In the Edit Batch Sequence - <name of sequence> dialog, use item number 3's drop-down menu.
From the menu, select 'Same folder as originals'.
"OK" out of the dialog.
Give the Batch Sequence a test run.
Output ought to be to the same folder as that of the selected & processed files.
Be well...

Tiff file size reduction

I notice that when I open a tiff file with CS6 and then close it, the size has been reduced. If I do the same thing with Microsoft Image software, the file stays the same size. Any idea why? As far as I know I am not telling Cs6 to compress the file.

Using PS CS6 with NO changes applied to the original TIFF the JPEG file size is 8.686 MB. The slightly larger file size is due to metadata differences between LR and PS.
Both Adobe applications (PS CS6 and LR 5.71) are producing near identical and much larger highest quality JPEG files. PS 12 Quality is the same as LR 100.
SUGGESTION:
1) Close LR and rename your LR Preferences file by adding the extension .OLD to it:
Mac OS X
Preferences
/Users/[user name]/Library/Preferences/com.adobe.Lightroom5.plist.OLD
Windows 7 & 8
Preferences
C:\Users\[user name]\AppData\Roaming\Adobe\Lightroom\Preferences\Lightroom 5 Preferences.agprefs.OLD
Reopen LR and it will create a new Preferences file. Try the JPEG Export again using the same settings as I have posted.
2) If still no change I suggest uninstalling LR, delete the new LR Preferences file created in step #1 above, keep the .OLD Preferences file, and reinstall LR 5.71.
3) If all is well now close LR and try restoring you original Preferences file by renaming the new Preferences file something like .OLD.OLD and removing .OLD from the original file.

Reducing File Size in Photoshop

Hello,
I had a question on reducing the image size after editing in Photoshop.
After doing my changes in Lightroom, I typically make edits in Photoshop and then do some final touchups back in Lightroom. The RAW file from my camera is approximately 24 MB. After making my edits in PS, the TIFF file it produces (with all layers flattened) is in the 60 MB range.
My question is, if before sending in back to LR, I change the image size in PS say to 12 MB or so, am I basically creating a lossy jpg file? Meaning -- by reducing that TIFF file size down to 12 MB am I throwing out important information such that when I go back to LR I am losing information and won't have as much control as the 60MB TIFF file?
I am trying to avoid having to keep upwards of 80MB per image (due to the RAW + edited file). I don't want to lose imporant information so I will if I have to, but would prefer not.
Thanks,
Scott

If you reduce the file size in Photoshop you reduce the pixel dimension of the photo which means that you throw information away - independantly if you save as JPG or as TIFF or PSD.
That means that the reduction in file size is a reduction in image quality.
If you want to print the image you need a certain resolution (dpi) for the print - typically 300 dpi.
If you want to make a print of let's say 8" x 10" at 300 dpi you need a pixel dimension of 2400 x 3000 pixels which results in a file size of roughly 22 MB (flattened file).
If you have reduced your file to 12 MB you cannot make a print of 8 x 10 at 300 dpi without upsampling first, i.e. Photoshop (or Lr) have to "invent" the missing pixels.
So reducing the file size is simply not an option - unless you use your images exclusively for the web where you don't need large file sizes.
If you edit your Raw files in Photoshop you have to live with large file sizes.
The only way to avoid that is: Do edit in Photoshop only if you absolutely cannot do it in Lr.

Large Tiff files

In our digital print department, all of our techs use PC's, we are seeing really large tiff file sizes. Our techs are opening pdf files in Photoshop, flattening them, and saving as tiff's. The file size of the tiffs are much, much larger than the pdf files before flattening. Our techs just started seeing this recently. Can someone tell me how they usually make tiffs (settings used) or if there is a hidden setting that might need to be changed?

This is entirely normal. A TIFF will almost always be larger than a PDF, unless the PDF was raster; most are vector. However, if the files are larger than before, you probably have a different resolution than before.

How do I keep the same file size, going from tiff to jpg?

Going from tiff to jpg, how do I keep the same file size? Seems like I am not able to save the jpg´s in 16-bits... Thanks!

file size? you mean dimensions or file bytes ?
Jpg is compressed so it won't be the same
Tiff is losless / lossy format to get the better quality
as for 16bit jpg the format doesnt support it

Merge TIFF file Resolution and page size differs. Clue ?!

Hi All,
I'm able to merge multiple TIFF files into one. But the resultant multi page TIFF file has different resolution and page size than from the source files. The width and height will get exchanged, also those texts are appear stretched.
Noteably, it happens particularly with FAX pages of TIFF files, not with any others (like printed page TIFF files).
can you help me ? Please write here your points.
Thanks a lot,
Vasu

I see I attached the link to the wrong discussion. It should have been this one. Scroll down to the workaround posted by Tomas, from August 26th.
http://discussions.apple.com/thread.jspa?threadID=1078666&start=0&tstart=0
Anyway, yes, that's sort of what I mean. On my iWeb 06 website, I've scaled all my pictures down to 800px x 600px with a resolution of 72dpi for online viewing. The original photos, say 3000px x 2000px at 300dpi, are simply saved on my harddrive and not used in iWeb. The thought behind that was for faster loading times for people visiting my website. I'm pretty sure when I saved these reduced copies in Photoshop, the default color profile was sRGB. However, when I look at my site on my office (Windows) PC, the pictures appear dark, especially Black & White ones. But the color profile is a separate issue covered in Tomas' workaround.
Now, maybe I'm operating on a false assumption, but I thought with this new download feature in iWeb and .Mac Web Gallery you would want to use your photos in full resolution so that when a visitor sees a picture they like, they can download the picture from your site AND could even print it if they so chose. Again, I'm assuming you would use your full resolution photos when you build your site and iWeb would do its own scaling for viewing on the web, but the full resolution photos would be somehow held in reserve for the moment when someone selects 'download'. I'm just concerned that using an unscaled, full resolution photos, would slow down the page building speed so much, that visitors would be too border to bother waiting for the pages to load. Thanks.

.tiff file mystery: file size huge, but document size small

Sorry for not finding a better way to word this, but this is the situation:
We're working on a project, and received .tiff files from the photographer. The files were around 33MB each, and 4600px x 6500px.
We've just opened the files today, and the files are still 33MB each, but the dimensions are now 222px x 295px.
I've never seen anything like this before. I've tried looking online, but I'm not even that sure what to look for. We're waiting to have the original files sent over again from the photographer, but until that time, I wanted to know if anyone has ever encountered this problem.
It seems like the fullsize information is still in the file, given the fact that the .tiff files are still the same size, it's just that even when you get info on the file, the doc size is tiny.
I'm working on an Intel based Mac, using MAC OSX, and running CS3. I've tried opening these files on a PC, tried opening them with previous versions of Photoshop, and tried opening them with other programs. It seems to be a problem not with the programs, but with the files themselves.
The files came with corresponding .xmp files, but I'm not familiar enough with them to know if this has anything to do with the issue.
Sorry if I haven't worded this well, but I'd appreciate any advice if this sounds familiar at all. I've never come across this issue before.

You will need a special plug-in most likely. The files are probably fine--you are getting a preview or thumbnail.
Look Adobe DNG plugin or Phase One to process the files.

How to export the same mb size of my cr2 files into jpg or tiff files in Lr?

How to export the same mb size of my cr2 files into jpg or tiff files in Lr?
Let's say my file size is 22mb, when i export the file to tiff or jpg, although Iam careful with the settings- file size, dimension, resolution, I can't manioukate how I want it.
With jpg I tried everything, no matter what i do or change in files size or resoltion it remains the same size- 7mb as opposed to 22..
Please advise,
Best wishes,

I would noramlly opt for a tiff file, sending such a high res through the nest a nightmare
This is probably just an improper use of terminology, but the resolution of a JPG, DNG and TIF should all be the same.
The files differ in size, not resolution and not number of pixels.
Jpg is not that bad, but its a pitty they have to be edited under a jpg format..
Your raws are edited as raw. There is no loss of quality in the editing process. The files are then exported as JPG, which will cause a loss of quality. For just about any use, the loss of quality in the image when you export a JPG at quality level 12 is NOT noticeable. For many uses, exporting a JPG at a quality level of 8 will not be noticeable either, unless you intend to print the photo at a very large size. As twenty_one (not his real name) said, "Jpeg compression is fantastically effective".

16x9, 300ppi, 75mb tiff file, LR converts to 1mb jpg. Export in LR 5 is being done at 100%, no file size reduction.

I've got a 16x9, 300ppi, 75mb tiff file that LR converts to 1mb jpg. Export in LR 5 is being done at 100%, no file size reduction. Can't figure out why it is downsizing so small? Even upsized to 420ppi in PS and the export was still only 2mb. Stock agency wants 3mb .jpg minimum. Any help appreciated. Thanks.

Using PS CS6 with NO changes applied to the original TIFF the JPEG file size is 8.686 MB. The slightly larger file size is due to metadata differences between LR and PS.

Choosing an optimal size ( file size, MB's,tiff or jpg) for iphoto

I apologize to Old toad and others who have responded. OT seems to be the only one who answers so much. He deserves a standing ovation which i am giving him now.
But:
Lets start at the beginning. I am a semi-pro (i do not make my living on my photography) who never used Iphoto but must now because i wish to create a 100 page book.
I have files mostly tiffs that range from 17.2 to 60 MBs in size ( 3008-5000 /2000-3000 dpi ). I see that Iphoto ad nauseum creates a thumbnail, and a copy of the original photo for each photo. This is not HD friendly.
How big in pixel size/file size in MB's should the files be so that i do not use so much HD space? Should i just go ahead and drag the files that i have and allow for 5-10 GB of photos to accumulate on my HD? I realize i do not need
my files so big and that is why i ask here in the forums.
I realize most of my files are non compressed tiffs,i.e. big in file size.
What say you? Please be specific. Mention a specific file
size in MB's please
thanks

Glen:
I've created several books. They were with cameras that produced 1600 x 1200 pixel image files which will give a maximum 300 dpi size of 5.3 x 4 inches. All of my books have been the Storybook theme so the one photo per page is not a full page and I've never run into the warning for low resolution. Possiblly a full 8.5 x 11 photo page would have given me a warning. For the intended use of the books I found them to be very good. My Canon camera's color profile is very close to the Apple recommended sRGB so I've calibrated my monitor with the sRGB profile. Any edits I do with Photoshop CS3 embed the sRGB profile in the resulting file.
My current camera gives me 2272 x 2704 images. Haven't ordered a book since I've started using it but am in the process of creating one right now.
It's not the MB size of the file that's important but the number of pixels in the image. For a full page photos, an image size of 3300 x 2250 would meet the optimal 300 dpi of the printing by Apple's suppliers. However, I have no doubt that my current camera's files would produce a good print at that size. That is if I got a good sharp image to start with.
So a 3300 x 2250 pixel jpg would provide just as good a print as the same sized tiff. Just keep as many pixels in the image as you can. For those good photographers that can do their cropping when they take the image that will maximize the files pixels for printing. I don't have the eye for that. But then my photos are of rapidly changing family situations and I don't have time top compose the picture.
I asked Apple about the printing and quality of materials used in the books and here's their replay:
I contacted Apple and asked for information that I could pass on. Here's the reply I received from Apple:
"Thank you for contacting the Apple Print Products Customer Service.
I understand that you would like to know the printing process that is used and the color mode the files should be in, so you can better advise users in the iPhoto forum.
iPhoto version 4 or later, allows you to import and print files through the Apple Print Product service as RGB, grayscale, or CMYK color space. JPEG files with RGB color space are recommended for best results.
While iPhoto 2 can import files of various formats, including RGB color, grayscale, and CMYK, this version requires JPEG files with RGB color space when printing photos and books.

Here are some of the technical specifications for the books, cards, and calendars. I hope this gives you an idea about their quality and form.
BOOKS
All iPhoto books are printed using acid-free paper for long-lasting image quality. The photos are printed at a high resolution (300DPI if you use iPhoto 6). There is no external modification--such as sharpening or contrast adjustment--of the photos; what you see in the application is what is printed in the book.
Hardcovers Books
The cover is hard-bound and covered in linen. You select the linen color during the book-ordering process. The hardcover books have a solid, stiff binding that is glued and crimped. The internal pages, measuring 8.5 x 11 inches, are printed on McCoy 100# Text Gloss paper stock.
Softcover Books
The softcover books come in three sizes:
- Large 8.5 x 11 inches
- Medium 6 x 8 inches
- Small 2.6 x 3.5 inches
All of the softcover books have internal pages that are printed on McCoy 100# Text Gloss paper stock. The large softcover book has a white cover (Kromekoteplus Folding Cover, 16 point) with a cutout on the front that reveals the cover-page photo in the book. The covers for the medium and small softcover books have the cover image and title printed directly on the cover. All of the softcover books have a glued binding and feature a thick cover of McCoy 100# Cover Gloss paper stock.
CARDS
All cards are printed on McCoy 120# Silk Cover paper stock. The postcards measure 4 x 6 inches, and the greeting cards measure 5 x 7inches.
CALENDARS
All calendars measure 8 x 10 inches and are printed on McCoy 100# Silk Cover paper stock.
To ensure the best print quality, we have chosen to use Kodak NexPress technology. The press uses a dry toner, which is fused to the surface of the paper. Please see NexPress' site for more information:
KODAK NEXPRESS 2500 Digital Production Color Press
I hope you find this information helpful in answering questions on the iPhoto forum."
As Apple stated, I hope this information is helpful.

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 written 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. You can download it at Toad's Cellar. Be sure to read the Read Me pdf file.

Tiff file image size discrepancy

Hi All, I've created a mono, bitmapped image approx 400px square.
Then saved the file.
If I go to 'get info' (I'm on an Apple Mac), it says the file size is 97k.
If I open the file in P'shop (CS5.5) and go to 'Image Size', it says the file is 19.2k.
Anyone know why I get two different files sizes?
Many thanks, RP

I'm sure that the TIFF file and Photoshop "Image Size" are both 19 KB by coincidence. The "Image Size" is the number of bytes consumed by the uncompressed pixel data. A TIFF file has to contain a header, so the image data in the file will be compressed then the file header will be bringing the file's total size to 19 KB.
Photoshop embeds metadata in TIFF that your client most likely does not need. Use your Mac's Preview app to reduce the size of TIFF:
In Photoshop, copy the image to the clipboard.
In Preview, do "File > New from Clipboard" followed by Save with format TIFF and compression enabled.
(Do not open Photoshop-saved TIFF with Preview and then re-save, because the unnecessary info will be maintained. Use the clipboard.)

Saving TIFF with LZW compression results in larger file size.

I know this never used to be the case with previous versions of Photoshop, but since I upgraded to CS5.1, when I save files with LZW compression checked, the resultant file size is higher than if I uncheck the box.
For example one file with LZW compression is 56.3MB, and without it is 47.8mb
Is it just me, or have Adobe got their code mixed up?
Edit: This appears to only affect 16-bit images, with 8-bit images, LZW works as expected.

File Size of PDFs in Preview

I scan a lot of documents for record keeping purposes. I set the scanner to 300 dpi, black and white. This keeps the file size down and the document is readable and printable (close to the original), and the scanning is quick. I scanned three sets of documents (about 15 pages each) this way and saved them as PDFs. The file sizes were 3.1 MB, 3.2 MB, and 1.8 MB. I used Preview to combine the three documents into one PDF. The resulting file was 19.3 MB. Why so large? 3.1 + 3.2 + 1.8 = 8.1 What is going on here? How do I keep the file size down when using Preview? I don't want to buy PDF Studio (or some tool like it) if I can avoid it (they all seem so mediocre).

Try Combine PDFs
<http://www.monkeybreadsoftware.info/Freeware/CombinePDFs.shtml>
I scan at 600 bpi into TIFF, then use Graphics Converter to save with the CCITT 4 compression. I get about 12:1 compression, with no loss of quality. The result is still TIFF, so you don't have to uncompress to use them.

Reduce PDF File Size - any ideas?

Hi all,
I have a C++/C# programs that generates PDF's in Adobe Reader using Infragistics. This is a recent change from using VS View as our old method of illustrating - we now use Infragistics. This has resulted in our PDF File sizes almost doubling due to us now using Bookmarks within the PDFs and also having to embed the fonts. There are some pictures used but these are already very small so they are not the issue. I was wondering does anyone have any ideas of how we could possibly reduce the size again or any possible work arounds.
Any help would be great.

Where do these EPS files come from Photoshop or Illustrator?
Illustrator
There may be nothing wrong with EPS files technically, they are considered archaic in a modern workflow. Best to save as a .ai with pdf compatible file - or to save them as PDF x4a with Illustrator Editing Capabilities enabled.
But I don't think there's any need to run out and convert all your files - perhaps keep it in mind going forward.
Photoshop
EPS is really not the best format. If it's pure raster then PSD or TIFF would be preferred format, if it's Raster + Vector Shapes, Vector Masks, Text Layers then PDF is preferred over EPS (with photoshop editing capabilities enabled).
File sizes react differently depending on the content on the choice of compression. Heavy Vector files from Illustrator can cause Huge file sizes in PDFs.
See this article (and more importantly the comments!)

If you can provide a bit more info on your workflow and what settings you are using to save it would be great.
