Export large TIFF scans to JPEG results in distorted "banding" effect

built-in JPEG converter, when used to send TIFF files to a .Mac screensaver or when used to export TIFF files to JPEG, results in distorted images on certain kinds of TIFF files, resulting in portions of the image displayed in vertical stripes across the screen... this seems to happen mostly to landscape-oriented photos which were scannned from 8x10 at 48-bit 600dpi (5960x4699) with a file size around 100MB... but does not occur on similar scans in portrait mode (4699x5899)... indicating a possible horizontal resolution limit around 5000?
tested same files in GraphicConverter, resulting in output without this problem

I Additionally, when I convert the file using the save as command in Preview, I can convert it into a jpeg or jpeg2000 and it is much smaller (71GB for example), but the same anomalous behavior occurs when I finish editing the file and quit iPhoto- - when I double click the thumbnail, the full sized image appears briefly and then disappears. leaving in its place a completely black window. I would be most appreciative of any insights.
Thanks.

Saving large tiff files as jpeg

Hello, experts:
I scanned, as a tiff file, a full-centre spread of a large newpaper. This had to be scanned in eight sections, the pages were so big on my A4 scanner window. When I joined all the sections up in Photoshop CS5, the size of the file was huge (about 21 inches by about 19 inches) It is also digitally large (about 320 MB, since the resolution is 300 dpi). Because I want to keep the composite photo but don't want the file to be so digitally large, yet need the good resolution, I thought it would be a good idea to save it as a jpeg file, which would give me the dimensions I need but not be so digitally bulky as the original. On pressing the drop-down menu for Saving As, the jpeg option did not appear in the dialogue box. Why is this, and how may I save the file in jpeg format? With grateful thanks to any/all that can offer a helpful response,
True to form

Curt, I'm very appreciative of the help you have given so far. However, I did try to change the image to an 8-bit as you recommended, and, though it is possible to make this change, and thereby reduce the sheer amount of data in the photo, when I click to choose 8-bit, the picture goes all bright and weird. This is because when I click on 8-bit, a window also arises, called HDR toning. In this window are lots of sliders, and, try as I may, it does not seem to be possible to adjust anything to make the picture normal in appearance. If you have any useful comment on what to do to make the picture like it is before the change to 8-bit, I should be glad to hear it. Thanks in anticipation.

How can I in DETAIL export photos in TIFF instead of Jpeg for large prints? LR5

I want to blow up some prints into large formats.... How can I export in TIFF instead of Jpeg in LR5?

I think Jao's right about pointing you at some beginners' guidance, but there's precious little "detail" invloved in the process, so:

Need help exporting large file to bitmap format

I have a large file that I need to export to a bitmap format and I am experiencing unknown "IMer" errors, memory and file size limitations.
The file contains only one artboard of size around 8000 pixels by 6000 pixels. I can successfully export as a png at 72dpi giving me a 100% image of my AI file. However I need to export an image at 200% of the AI file. If I export as a png at 144dpi to achieve this I get the following error(s)
"The operation cannot complete because of an unknown error (IMer)" or "Could not complete this operation. The rasterised image exceeded the maximum bounds for savung to the png format"
I have tried exporting as tiff, bmp and jpeg but all give "not enough memory" or "dimensions out of range" errors.
Does anyone know the limitations with AI for saving large files to bitmap format?
Does anyone have a workaround I could try?

You could try printing to Adobe Postscript files.
This will actually save a .ps file and you can scale it to 200% when doing so. You'll need to "print" for every image change.
Then open a Photoshop document at your final size (16000x12000 pixels) and place or drag the .ps files into the Photoshop document.
I just tested this and it seems to work fine here. But, of course, I don't have your art, so complexity of objects might factor in and I'm not seeing that here.
And you are aware that Photoshop won't allow you to save a png at those dimension either, right? The image is too large for PNG. Perhaps you could explain why you specifically need a png that large???

Color shift when exporting to tiff

Hi,
I have a vector image which I created using multiply transparency layers, however when I export it to tiff or import it to psd, the color changes (it gets darken). The ai file is in cmyk.
The image is intended for print and will most likely be place in a word document. How should I set the color setting/profile so that I could get a consistent color across the different file formats?
Thanks so mcuh for you guys help!!!!

Hi Kwaim
Please do a test:
You take an object and set multiply to interact with others, ok? So select that object and all object underneath influenced or token by multiply. Go to Object > Rasterize. Select high for the resolution.
After process, color changes?
If yes, stop and report me
If no, try exporting to tiff and tell me results

Red Box - Unsupported File Type - Large Tiff - Large Scans - 10,000 pixels

Hello All,
I am a user of Aperture 2.1, and I have grown to love the program except for one major issue. Large files that are imported into the program are simply unsupported.
I scan 6x7 medium format negatives (8649x10712 @ 530.2 megs) and 4x5 negatives (very large drum scans) into my system (new 8 core, 12 gig ram, 512 meg vidcard, 10.5.2) and the issues begin. A thumbnail is properly built. Once the thumbnail is selected, and a preview is built, the image appears briefly and is replaced by a red box soon with the text "Unsupported File Type". If I change views to full screen all I see is a red box with the same text. Ie. I can't work the image.
The files are perfectly fine. I work them in photoshop cs3 no problem, and I can view them with quick look preview no problem.
This is highly frustrating as I work primarily in larger formats and create large prints!
It seems like the bug occurs in files that have a side larger than 10,000 pixels. This is a massive issue to large format/panoramic workflow!
I have called Apple tech support and the techs claim ignorance. That could mean they do not know of the issue which does not bode well for a solution. I'm in the dark. Please shed some light!
Three questions:
Is anyone else experiencing these issues?
Is there a workaround that doesn't involve cutting file size?
Has there been any acknowledgment from Apple support regarding this issue?
I am most frustrated as Aperture is billed as a professional product, but it is unable to keep up with the demands of a working fine art photographer.
Awesome product but needs some adjustments!

William, thanks for your input, but I feel that your position avoids the primary issue. Aperture is a Digital Asset Manager, and as such, should be able to manage digital image assets.
From Aperture's Webpage: "See how Aperture lets you import, manage, and enhance your photos in one simple, integrated workflow." It says photos, not Raw photos. In fact, I'll take it one step further, in the tutorial CD that came with 1.5, the narrator mentions the 16-bit workflow in Aperture with Tiffs, more than once.
I purchased Aperture for management and integrated workflow. Apple states: "Now it’s even easier to cull through shoots, enhance images, manage massive libraries, and deliver stunning photos." No where does it say that the functionality of the program is limited to RAW files. Ie. Apple never mentions that Large .tif files are not supported.
I have 6x7 and 4x5 Scans, Masters, Working Images, Print files and Web images that I would like to organize, stack, label, rate, view versions simultaneously on my second screen, sort, arrange, and keyword. The program's basic functionality is thwarted by an issue that Apple has not owned up to.
If Apple had mentioned in its literature that large .tif's weren't supported I would not be posting this, as I would not have purchased the software. But nowhere, not in phone conversations with Apple Techs (3), not on their own Forums where other end users have hit a massive workflow brick wall, and not even after I mentioned to a One on One guru, has Apple said, oh, yeah, we are aware of it and working on it. There is no transparency here.
Now, I have purchased Aperture, learned it, and imported thousands of files into it. I like the program as I have seen it function with smaller files perfectly, but this large file issue needs to be overcome.
Regarding editing images, yes I use photoshop for the majority of my post-production. I then use a finely tuned Colorburst Rip on a nice Epson for my Fine Prints. Those are the functions of the respective programs. Aperture is a DAM, a program that among other things allows the end use to manage their files effectively and maintain a strong workflow.
Regarding space - esata is a beautiful thing.

Lightroom 4. I have a large image (scanned) 10,000 X 14000 which does not Render when I try to print or export. Regular sized images work fine.

In Lightroom 4:Mac OS 10.6.8. I have an expecially large image (scanned) which is 10,000 X 14,000. I have edited it but when I try to print or export the image, it starts to "Rendering Page" but gets stuck and is unable to complete the task before it times out. When I use normal sized photo images (raw), it works fine. I suspect the problem is related to the size of the file. Is there some way I can reduce the size of the image while in Lightlroom? Or is there any other solution?

You originally posted on a thread that really wasn't related to your problem, so I branched the discussion.
Check the Windows System Event Viewer to see the details of the crash, most importantly the name of the faulting module.
Most crashes on Open or Save are due to OS bugs (especially on MacOS) or bugs in third party extensions to the OS open and save dialogs.

Scanning (Into JPEG) of Plain Paper with few graphics results into multiple images on HP 3545

Scanning (Into JPEG) of Plain Paper with few graphics results into multiple images.
Whenever I scan a page which is almost a white paper, but has some graphics on it, then the Scanned Files is not a single, rather it becomes in multiple parts e.g. circle in one jpeg file, square in another jpeg file. However the scanning to PDF works fine. Please let me know if this is manufacturing defect or defect in the product I purchased.

This only happens if I scan plain paper with few graphics. But scan to jpeg is working fine if the page has multiple objects

Unable to save exported Aperture TIFFs as jegs when opened in Photoshop

I'm using the latest version of Aperture and need to do major retouching of the images I have edited using Aperture. When I "export versions" of the images, I normally choose "TIFF-50% of size" or "TIFF - fit within 1024x1024", but when I open them with Photoshop, after I worked on them I am unable to save them as a jpeg. The option just doesn't come up.
The only save options I am offered are - SAVE AS - Photoshop, Cineon, Dicom, FXG, IFF Format, Large Document Format, Photoshop PDF, Photoshop Raw, PNG, Portable Bit Map or TIFF.
Any idea why this is happening and how I can rectify? I need to use photoshop for my retouching and I don't want to have to export RAW files from Aperture, it's much simpler exporting a TIFF.

The tiff is a 16 bit file. Go to images/on the photoshop menu and convert to 8 bit. then the jpeg option will show up.
Cheers

Automatically Slicing Large TIFF Files with Photoshop 5.1

I am trying to automatically slice a very large TIFF file (800 MB) into 28 equally-sized rectangles using Actions (it is a scanned image of 28 scientific slides and reducing the resolution is not an option). My goal is to start with the TIFF file and end up with a folder that contains 28 separate files. I'll do this on many such TIFF files, so it needs to be coded into an action.
So far I have an action that creates guides in a grid pattern and then converts the guides to 28 individual rectangular user slices that together cover the entire screen. Unfortunately the file is far too large to use with the "Save for Web & Devices" tool and I also can't export to TIFF from that tool. So I made an action that individually selects each slice (using the slice select tool), copies it, creates a new file, pastes the image, saves it as a flattened, non-compressed TIFF into a new folder, then closes the file. When I try to run this I get the following error:
The command "Select" is not currently available
          -- Continue --       -- Stop --
If I press Continue the action is not carried out. If I press Stop and select the slice manually there is no problem (but then my action will not be fully automated). The image is in 8-bit RGB mode, and I've also tried converting the locked Background layer into a standard layer. I don't see any reason why the select command shouldn't be available! There is only one layer and there are user slices available for selection. I tried separating the slicing and select/import jobs into 2 different actions but it still didn't work.
Any help you can give me would be greatly appreciated! Thank you!

Performance large TIFF

Just identified the reason why some of my large TIFF files bog down Aperture, while others fly: LZW compression.
Especially large 16-bit TIFF images take forever to load and zoom in on. And yes, I know that LZW makes no sense at all for 16-bit, but it happened by accident. As it turns out, 8-bit TIFF images with LZW compression also incur a significant performance hit.
And it is not just Aperture, also Preview takes much longer to display compressed images. Somehow I expected the decompression of LZW to be less cpu intensive than JPEG, or is this a systemwide bug?

Chuck - My response isn't exactly on point, but, I resize JPG image proofs to 1024x768 pixels (the iPad screen size) and they look great, lots of detail. I use the same process for my Samsung 53" LCD screen except size to 3840x2160 with spectacular results.
I'm a professional photographer, and I'm going to use iPads to present proofs to my customers. Hope this helps - IM

Can I use preview to export multiple page PDF as jpegs?

Using Preview, I export multiple page PDF as jpeg and results are the first page only as jpeg. Can I use preview to export multiple page PDF as jpeg for every page?

Automator is great for this if you need to export many pages to JPG, or just have to do this often.
Two other quick and dirty way sto get it done:
(1) Enable thumbnail view, click on the ONE PAGE you want to convert to jpg, then choose "export." If you choose more than one page, only the first will get exported to jpg.
(2) Create a copy of the file, delete all the pages except the one you want to export to JPG, and export that page. You may be able to "undo" the delete, get all your pages back again, and re-delete all but the one you want to export, etc. I would not recommend doing this on the original version of the file because of Preview's autosave so-called "feature."

Error message exporting large picture file from Aperture 3.5

Recently I took a large panaramic comprised of 165 pictures using Gigapan Epic Pro and stitched together using software provided with Gigapan. I exported the stitched file into Aperture to perform final edits. When I go to export the final version I keep getting an error message. The file size will be approximately 2.0 GB. I've been able to export a 0.7 GB file without problems (it did take several minutes). I have a late 2009 27" iMac with 3.3 GHZ Intel Core 2 Duo processor and 16 GB memory. Any suggestions? Not sure if this is an Aperture problem or if my system is not up to the task. Below is the error mesage I receive. Thanks for your assistance.

Sorry, let me clarify my questions as they were ambiguous:
For a given set if input, does the request always take the same amount of time to fail? How long does it take?
When it works (e.g. on local machine using same input), how big is the output file that gets downloaded?
Also, if you can share your site name (directly or
indirectly), and the UTC time where you made an attempt, we may be able to get more info on our side.

No longer able to Scan to JPEG using HP Phtotosmart 2610

I no longer have the ability to scan to JPEG format using my HP Photosmart 2610xi using the Apple HP Printer Driver 10.3. I now only have TIFF, PNG and PDF formats available to me. Software update does not recognize the need for an update to the driver. This is a new issue as I have always been able to scan to the JPEG format. My bank requires that any checks I want to deposit via the web have to be in JPEG format. I am running a Mac Mini with OS 10.10.3.

Hey,
Install the HP Easy Scan app from the Mac App Store, then open it from the Applications folder:
