Photoshop :: Compression Options When Saving As TIFF
Mar 7, 2012
Adobe Photo Shop CS5 offers three options for conversion of a RAW file to TIFF (LZW, ZIP, and JPEG).
I do not understand which of these employ the "run-length encoding" scheme that should make the TIFF file much smaller than the RAW file. I have used all three types of compression but the only one that resulted in a substantial reduction in size was the JPEG compression.
The TIFF file with no compression is actually twice the size of the raw file. What are the LZW and ZIP compressions actually doing?

very slow saving of TIFF files I came across several articles online ("The Mac Performance Guide" being one of them) mentioning that if you turn off compression for TIFF files it'll take a lot less time. The problem is I can't seem to find any compression settings at all.
I'm using Photoshop CS4 on a Mac, mostly editing via Lightroom 3 first (I suspected the issue being that Lightroom opens up the files as 16 bit in Photoshop, but even 8 bit images in Photoshop won't give me any compression options). The above link specifies CS3, CS4 and CS5, so it should be in there somewhere.

When you export from Illustrator CS6 or CC in TIF format, you are given the checkbox option of LZW compression, but the output file does not seem to be compressed. When I open this TIF file in Photoshop and do a Save As, selecting the LZW option produces a dramatically smaller file than the one produced by Illustrator.

I have thousands of tiff files in my LR 4.1 catalog. I'd like to convert all of these files to tiffs that use zip compression. Preferably, I'd like to do the conversion in-place but LR won't allow me to overwrite the originals in-place.
So, I think I have to either export all of the images and either add them to the catalog during the export process *or* manually import them again.
I do *not* want to lose any of the LR edits I've made to these files and I think I will do exactly that if I use either of the conversion methods I noted above.

After working on a jpg file, when I want to save it, still as jpg, with my Photoshop CS5,
- sometimes photoshop will just save the picture, and it's done
- sometimes photoshop will show me the compression dialog, "JPEG Options", in which I can choose the compression ratio, the format options (baseline, baseline optimized, progressive), and have an estimation of the total file size
While not being prompted any dialog is simpler, and I'll then simply assume Photoshop decides to retain the current image's compression and format rules, I must say I like to be in control, and I'd like to know under what form the file is being saved without having to resort to the much more complex "Save For Web" menu.
WHAT "triggers" the appearance of the JPEG Options when we close/save a jpeg file, in photoshop ? What makes this menu not to appear, what makes it appear ? If there are trivial file operations/changes/filters that necessarily trigger its appearance when we want to save, something like that ?

When I save a PDF file in Photoshop CC in CMYK color with JPEG compression (quality = high), it will save without any errors. However, when I open the file in Acrobat, I get an "Out of Memory" pop up error. I press Ok, and the document is just displayed as a blank white image.
I'm using Win7 64-bit, Photoshop CC 64-bit. Plenty of memory (24GB) and allocated RAM in preferences, and I've done some troubleshooting that leads me to believe the error is not due to system memory, but rather a specific bug in the software. I have Photoshop CS6 on the same machine, and if I open the PSD, save as PDF with the above settings, everything is fine when I open it using Acrobat. This seems to just be for Photoshop CC, not CS6.
Here is the troubleshooting I've done so far:
PDF format, RGB color, any other settings --> Acrobat can open the file.
PDF format, CMYK, no compression --> Acrobat can open the file.
PDF format, CMYK, JPEG compression [medium] --> Acrobat can open the file.
PDF format, CMYK, JPEG compression [high] --> Acrobat can NOT open the file because it encounters the "out of memory" error.
PDF format, CMYK, JPEG compression [maximum] --> Acrobat can open the file.

Make beautiful gradients. I know, its by using different colors, but when the times come for saving the image ( i prefer png at compression level 1) you have to make it narrow(if gradient is perfectly vertical).
But if you crop lenght at 1px you always get inferior image after you put it in website as background for example. roping at 10px wide does work but it still not good enough..

For years I have been enabling Use Compression when saving files. I am not sure exactly what it is doing but I do know that file sizes can decrease dramatically. I have seen 100MB files got down to 10MB.
Well the other day a coworker told me to always disable that because he believes that any embedded images will be compressed and lose quality and/or have problems ripping with Nexus or Odystar.
Is that true? Illustrator Help says that the pdf information is compressed when enabling it. So are there any disadvantages?

I'm saving a tiff image from an Imacon scanner before opening in ACR and modifying it.Then, proceeding to Photoshop CS6 for Mac for further modification. On saving it will only save as .pbm and not .tif. If I modify the suffix is shows as .tif.
However, it will then not import into LR4. It will then open in CS5 Photoshop and it also tries to save as a .pbm, but it will easily change to a Tiff suffix and save and then re-open in LR4 as a .tif.

Photoshop 7 has suddenly started saving TIFF files without a preview or thumbnail. That is, I can't see the preview or thumbnail in Windows Explorer (Windows XP) or Windows Picture & Fax Viewer--which says "no preview available."
This just happened--I've just saved dozens of pics in TIFF with previews.
I tried resetting my Photoshop preferences--no change. In the File Handling Preferences, for Image Previews, "Always Save" is selected. When I save an image, in the "Save" dialog, "Thumbnail" is checked (and grayed out).
However, if I try to open a file from within Photoshop, in the Open dialog box, when I click on the file, I do see a preview.

I have a action that I use to convert RGB JPG files to CMYK. After it is done I save the file as tiff.
I want it so that the action does the save as tiff bit, but when I at the save as tiff bit to the action it remembers the loacation where a saved it. Instead I want it to save it in the same folder as the original JPG. So I can use it for different folders with JPG files in it.

I am trying to save a .psd to a .tiff file. My .psd has a couple layers and a drop shadow effect. When I save the file seems to be fine until i veiw it in any Windows or Microsoft view, thumbnail view or application such as word, it looks squeezed and totally washed out of colour and almost transparant? I have saved like this before and never encountered this problem. It seems to appear properly when opened in InDesign, Photoshop. I use these photos to send to other people who will be viewing them and using them in Microsoft applications such as PowerPoint, so I'm concerned that it won't open properly for them.
I am using Photoshop CS and Microsoft Windows Windows XP Professionl Version 2002 Service Pack 3.

I use CS5.1 and just recently when I go to save my edited file as a TIFF, the file is now blurry. I even tried to save a RAW file as a TIFF (with no editing) and it is still coming up blurry

saving and opening up as a .tiff or .jpg the black has faded and becomes much more weak, why is this? This happens every so often when I'm working with files, but I don't know the reason, maybe a setting I need to tick?
-I created my event poster in CMYK, the darkest black I used was 75, 68, 67, 90
-I have 1 photo (background mountains) that was orginally RGB and converted to CMYK when brought in.
-Tested merging all layers together and the outcome was fine, only after saving and viewing is it faded
-Could this be a monitor issue, or even the settings in my "preview" that are throwing this off?

1) I scan an image and its 300dpi. when i open it in ps its 72dpi. what's happening?
2) When i create a new document/clipboard etc to start working, i only have the option to go up to 8bit or 16 bit RGB... Can't it go any higher? does this affect item1?
3) if i try to drag an image into this 16bit window it tells me the target document has a different depth than source document and it will result in lower than expected quality..... how can i avoid all this?
4) Sometimes i can save my psd as jpeg and sometimes i cant... I dont get that option...what's going on?

I scanned, as a tiff file, a full-center spread of a large newspaper. 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 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?

Running a script to open up files and convert to another type. When it gets to a TIFF type file a dialog window titled 'TIFF Import Options' is opening. This windows has an Options column that contains two radio selections for 'Convert Layers to Objects' and 'Flatten Layers to a Single Image'. How would I open the file with the 'flatten layers to a single image' set?

I am working on a project that requires saving my image files as uncompressed tiff files and then saving another copy using LZW compression and being stored on a different drive. I am scanning a large quantity of herbarium specimens one after the other and then saving these files on two different drives.
Because I am working on a Windows pc it defaults to saving the file as the same type and in the same place as the previous one. As a matter of efficiency I just save the file in the proper form for whatever drive I was last on then save the next one in the form it needs to be for the other drive - alternating back and forth.
My question is: If I save the original scan as an LZW compressed file first and then "save as" a second copy as an uncompressed Tiff. Is there any loss in image quality saving a LZW compressed to to an uncompressed form. Should I always save the original file in it's uncompressed form first? Does the file remain totally intact in Photoshop regardless of what gets saved first…

I am cleaning up the Hard Drive on my Mac G4. My scanned images are taking a great portion of the 80 Gig drive. I finished clearing my external drive by removing nearly 60 gigs of images by storing them on DVD. I will do the same for the Mac drive.
My trouble is that all my images are stored in TIFF format which takes up enormous space no matter the storage. Since I output images in various sizes, mainly prints, to 30 x 40 inches, I need a master image archived in the best format for such. However, I do not want to fill my drives, or DVD, with large files. Code:

When I convert an RGB psd to CMYK color mode in photoshop everything works normally, but when I save as a TIF and open the file in any application other than Photoshop any white space in the image background is yellow.
I am running Photoshop CS4 on Mac OS 10.5.8.

I purchased PaintShop Pro X4 yesterday. So far, I am impressed with the speed boost gained but I have a BIG PROBLEM: I need to work with TIFF files but this version creates a two-pages TIFF file whenever you save one (they appear as a two-page tiff with some sort of thumbnail attached).
I have been tinkering with setup options but I have been unable to find anything relevant to this issue.

It seems I can either save work at a lower quality jpeg, or export to get higher quality and lose the EXIF. I never want to use the lower quality, never, but I cannot seem to find anything in the Preferences to avoid having to manually set the quality. Is there a way to save at a higher quality than currently provided by PSP X4 by default?

Is it possible to ask Photoshop to save TIFF images using tile internal storage rather than strip storage? A little-known setting, a registry patch perhaps?

I am using PSE 12 as an external editor for Aperture. When I ask to use an external photo editor, Aperture creates a .tiff file in my Aperture folder, launches PSE 12 and tells it to edit that .tiff file. This all works great. When I am done editing in PSE 12, I ask it to save the file and it saves it back to the original Aperture folder with a .tif extension. I can instead say "save as" and then it suggests the file name with a .tif extension. When I correct the extension to .tiff it warns me that I'm going to overwrite the file (exactly what I want!). I say yes and then I find out that PSE did not overwrite the file, but wrote it as a .tif file anyway. I have to go to the folder, delete the .tiff file and rename the .tif file to .tiff and then everything is fine - but what a hassle.

I'm trying to understand jpg file compression and how Photoshop deals with it. Let's say I have two jpg files of the same subject - one was compressed to 4.4 MB and the other was compressed to 1.2 MB. I was told by a friend that once they are opened in Photoshop, that it did not matter how much compression was previously done since opening them in Photoshop will uncompress them back to their original uncompressed 20+ MB file size and that you will not lose any image quality. So that a higher level of original compression will not degrade the photo quality since Photoshop brings back (uncompresses) the file back to the original size when the picture was taken.
