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.
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?
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.
Any recommendation for a quicktime .mov compression setting that results in good quality and a manageable file size?
Pro X3 Windows Vista
I'm doing a video and the client requested the final product as a quicktime file. I've had good results with creating .wmv files but haven't had much luck with .mp4 or .mov files. Using the "custom" option under "create video file" I select "Quicktime Movie Files" as the type. Every compression option I choose comes out crappy and a very small file size. When I select "no compression" the video looks great, but it's almost 2 gigs (the video is only about a minute long). The client will be uploading this video to a product page on Amazon and I think they have a maximum file size, probably around 500 MB.
I hope to convince the client to just accept a .wmv or maybe even a .flv file instead since I think Amazon accepts both of those. But in an effort to give them what they want, I hope to deliver in a .mov format.
Should all settings be zeroed before creating the 32 bit TIFF file in Edit in>Merge to HDRPro. Does this include defringing, sharpening, noise reduction and all basic panel settings?
Also the info I have been reading infers that only the the exposure ends of the bracket need to be input rather than all of the files in the bracket. Example from a -2,-1,0,+1,+2 bracket, only the -2 and +2 would be input into the Merge to HDR Pro.
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:
I am exporting graphics to TIF format and it needs to be exact same as in document, RGB code. I found out that if I uncheck the "Embed Color profile" it exports correctly with exact color codes as in Corel. However, sometimes I have found out that I have forgotten to uncheck that little box..
So I would prefer to have it unchecked by default. How would I do it?
I opened filters.ini and found the TIFF section, but I don't really understand anything there.
I have been working on a file in photoshop cs5 that had come from lightroom 5.3. This was then saved (automatically becomes tiff file in Lightroom). I then wanted to make some more adjustments to it in lightroom (using local adjustment clarity). I then tried to copy the settings of the adjustment brush from the tiff to the original raw file. This is where it gets very strange. The adjustments are copied but they are rotated ccw by 90 degrees! I can replicate this every time.
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.
I understand that the .jpg format is a compression file that will degrade over time after repeated saves using photo editing software.
However, does this loss of information from a compressed file still/also occur after the file has been placed into other programs such as InDesign, Word, etc.?
I've got a file of about 40mb which saves as a max quality jpeg in Photoshop at around 12mb. Once it goes into InDesign and comes out of the other end as part of a PDF the file size is down to 3mb.
I'm convinced data is being lost but one of the answers seems to indicate that zip compression is now being used in addition to the jpeg.
I always thought it was hardly worth zip compressing files like jpg, mp3 etc that are already compressed and that the only way InDesign could be knocking my jpegs down to a fraction of their size was by recompressing them as lower-quality jpegs?
I am trying to save an original vector psd to a jpg, however it is coming out with compression on it. I am saving it as maximum quaility level 12, but it still appears. Any ideas what else is causing this?
I need to create a Batch process that takes a directory full of sub-directories (which contain uncompressed Tiff files)and re-saves the TIFFs with LZW compression in the same directories WITHOUT creating any new files. My problem is that when creating the action the only way I can save with LZW compression is by using the "Save as" option. This creates new files and when I run the action it dumps all the files in whatever directory I am saving in while creating the action, instead of saving them in their original locations.
I have CS3 extended and have been compiling a series of high resolution photographs into one layer in photoshop. I have copy and pasted each photo and then stitched them together resulting in a file that is 1.35Gb. I want to compress the file, keeping the resolution as high as possible, so it is easier to use in illustrator and import into ArcGIS. I have tried saving the file as a jpg, pdf and tiff with variable compression qualities. As soon as i open the image up in a different programme and zoom in I loose the picture, eitehr to a blank screen or a message saying 'invalid format/picture'. Opening the file and saving is taking so long too do as well...
When I upload photos to[URL]... They will either be a very large file size and delay the download of the page or they will come out grainy. I have tryed adjusting them in Photoshop, but I will either loose quality or they will not be compressed enough. It there an easier tool that I am missing?
In relation to Photoshop, in the status bar at the bottom it displays what it calls “document sizes”. How to clarify can this be used to determin the quality of a jpeg file ?
For example if I open up a jpeg with no compression (file size on disk is 4.57mb) it displays Doc:34.5M/34.5M however if I open the same file with compression set at 5 (file size on disk is 748kb) and ‘document size’ doesn’t change. How does the document size relate to jpeg compression etc...?
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 ?
I use CS5 on Win 7 64-bit. Today I learned about this option to disable file compression to speed up save time:
[URL]........
I downloaded the reg key and installed it. When I restarted PS to test it on a file, there was no difference in either save time or file size. The test file is a 300 MB multi-layered PSD file.
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.
I occasionally use the option when saving an edited picture to just overwrite the original. I would have thought that this option might go further by having the program default of making the saved copy the the same size as the original or if its dimensions had altered save at the same resolution& degree of compression.
i have problems with images saved as jpgs in best quality. the same image saved as png is in much better quality, what is no surprise. but when i save the png in photoshop as jpg the no loss of quality.
1. jpg saved in max 2. png saved in max 3. png saved as jpg in photoshop
I have many images of slides scanned at high res (4800 DPI, maximum pixels 5214x3592). Although I will be saving these as loss less TIFs, I also wish to make JPGs from them that I wish to be just less than 5 MB in file size. Aside from cropping, I know I can achieve such a reduction of JPG file size by a combination of saving to lower quality JPG compression or reducing image size. My question is, what is theoretically or practically better, achieving this mostly by reducing image total pixels or by reducing JPG compression quality.
I'm trying to add audio to a slide show. I've done it before on this computer with no problem, but now it's telling me I don't have the correct compression files installed on my computer.
