Weird Photoshop PSD files sizes...

• PSD Photoshop CS6 file sizes vs TIFF

  I know that there are many threads there with regard to the advantages/disadvantages of savings in the PSD or TIF, but for the time being, I am still confused on some things and embarking on an exercise where I'll be editing or reissue a lot of images - that is why, I would like to do things the first time if I can.

  My immediate question is if anyone can shed some light on the reason why an image that I save as TIF is 395 MB (in the Finder) - and the same image saved as PSD with no other change is "55 mb.

  Over the years, I've almost always saved as TIF without compression - I never saved by any form of TIF compression.  But the disparity in this case between a TIF to 395 MB file and a PSD file 55Mo tells me there is something important, I do not understand.  Reason for the question is not only the huge disparity in the size of the file, but because I am also leaning heavily toward saving all my images under PSD as I advance in my project.

  My concern is I missed something in a 55 MB PSD file vs a 395 MB TIF file or PSD just that much more effective than TIF?  I have many other images that I saved as a TIF and PSD where the uncompressed TIF file is maybe bigger than the file PSD - but nothing like this one, with a gap of 55-395 MB 50pct.

  Would appreciate any comments from what seems like many who are well informed on the issue of PSD vs TIF.

  Thank you

  When you save a Tiff file you have much more save option.  You can save files compressed or compressed, you can choose what compression to use. You can save flattened or with layers.

  Save record PSD layers and you can set the size of the file with some of your preferences for the PSD in Photoshop files.   You can disable compression and save data options for maximum compatibility for older versions of Photoshop.

  PSD has a 2 GB file limit, but you can save the file larger layers using Tiff limited to 4 GB and PSB files limited by free space in other words of large file with PSB.

  Some applications can read a Tiff file, but not PSD files.  Some applications that can read the Tiff file will use the tiff full composite layer. They do not support the other layers. As Lighroom does not support layers other layers that are in tiff format are not used. TIFF with other layers have efect conposit layer lightroon conversions first changes is no longer can be adjusted to layer coposite necessitated changed by an image editior.

• the .psd file size is meaningless for me

  I hope someone can explain the size of the huge .psd files that I see.

  I have a Canon 7 d and shoot first.  I have a raw file that is 24.6 MB and is a pixel image 3456 x 5184. I then open with ACR and do nothing but save it as a file .psd of 16 bits with the same image resolution (pixels).  The .psd file is 102.5 MB.

  By my Calc a 3456 x 5184 x 2 bytes (16 bits) is 35.8 MB uncompressed.  Yet the .psd is nearly 3 times that size before it is already open in Photoshop.

  Can anyone explain why?  My 256 GB drive ate like a bunch of breath mint...

  Your assumptions are false.

  the "16 bit" RGB data have 3 colors per pixel bits x 16 per color.  Thus, 3456 x 5184 x 6 bytes = 107 MB and change.

  The raw file, I remember well, 14 bits per photosite of measurement data that has not been debayered.  The scope that one color of light is measured by photosite.

  Canon CR2 raw format and both include the Photoshop PSD format and compression without loss.

  I hope this helps clear of the things up.

• Repair damaged adobe photoshop .psd files?

  One of my project files has been removed in a terrible accident. I won't go into it, but I got one of the .psd files using a commercial conservation program (Fast File Undelete data DTI). It did not work (go figure) and whenever I try to open the file .psd photoshop (7.0) shows a message box that says: "there was a problem to read the data in the layer. Read the composite data instead? "When I click on the play button of Composite data another box shows that reads,"cannot open '[file name]' because the file is not compatible with this version of photoshop. »

  It seems as it is very close to work, because there isn't even a vignette. I also got a handful of .jpg and .tga, who are also broke. Does anyone know of a utility that could attempt to repair a .psd, .tga or a .jpg?

  Repair Kit PSD that repairs the Photoshop files and you give image repaired to the original format as well as repaired layers and the corresponding safe bitmap file.

  -Repair of PSD files developed using any color mode of Photoshop

  -Repairs corrupt the PSB ("large document format") files

  -Fix images with the DDP file extension

  -Provides the bitmap of the repaired Photoshop file

  -Takes to load Adobe Photoshop CS5, CS4, CS3, CS2 CS1

  DOWNLOAD SETUP FROM HOMEPAGE: http://www.psd.repair/

  SECOND FREE SOLUTION:

  Photoshop is adding sometimes a few bytes at the beginning of the file when the file is saved, then the same Photoshop gives an error and complained that the files... All you have to do is delete the Group of bytes that unnecessarily.

  Assuming that you know already what is a HEX editor and how to use it I'll write here a few steps, you can do before opening a "corrupt": PSD file

  1. make a backup (copy) of the file before making any changes.

  2 - Open the file "corrupted" in a HEX editor used (text editor NOT!) and look for such groups of fairness at the beginning: 8 bits/s and after a few bytes 8BIM another group of bytes, then 8BIM.

  3 - this succession must be respected strictly: 8BPS... 8BIM... 8BIM. these groups should be very close to each other and it is easy to find.

  4 - remove all the bytes before 8 group BPS (shift + delete) and save the file... =)

  5 - open in Photoshop and have fun.

• Save psd files exported from Lightroom to Photoshop

  Hello world.

  I really hope someone can help me, because I'm about to go nuts here. :-)

  When I export from Lightroom to Photoshop psd file, then I can not save the psd file in Photoshop before you close Lightroom. As soon as Lightroom is closed, there is no problem to save the Photoshop file.

  The error I get is:

  Cannot save 'Filename.psd' because

  write access has been failed.

  

  I use an iMac2013 with Yosemite 10.10.5

  I save on a WD MyCloud NAS box.

• Maximum size of the psd file of CS5 2 gig?

  I´m PS CS5 64 bit on a system Win7 w 4 GB of RAM running. I ve read somewhere on a PSD file size limited to 2 giga max.

  Still holds true?

  Same thing on a mac w 8gig of RAM (and PS CS5 64-bit)?

  Thank you all for your comments!

  Cheers, Erbs

  It can only be read by Photoshop CS or newer. Don't know about Illustrator, but it's probably the same for her. You can also try using the format of TIFF files that supports up to 4 GB in size, but once again, only Photoshop CS or newer will open them if they are beyond 2 GB

• Open bridge PSD files in Photoshop CS6

  In the previous version, with that I can open Photoshop psd files double click. Now, it will open in QuickTime only. How can I go back to the old way? And I don't want to "place" the intelligent file to objerct either.

  Help, please.

  In Bridge cs6 look in preferences (Ctrl + K or Cmd + K) Bridge, then under file types Associations, where you can choose which applications to open files of the bridge.

  

• PSD-file is not compatible

  Open a psd file in Photoshop CC 2015, the program responds by saying that the file is not compatible. I made the file CC2014 or CC2015 and then worked on it in CS6. Now it does not work on two programs

  Changes with each new version of Photoshop PSD file format, so it is built into the functionality of compatibility built in for when you save should you want to go back and use earlier versions. It was not many changes between PS2014 and PS2015 but CS6 is old and there are differences.  It seems that if you have which off preference saving mode of compatibility and openness to CS6 corrupt the file. .

  

  To activate the dialog box above go to preferences under Edit and change there.

  

  If your file is large PSD files can be repaired with a tool like repair PSD of Phoenix, but you'll probably lose something.

  Hope that helps

• It cannot open photoshop CS5 file...

  Hi all. I am working on a few illustrations in photoshop CS5 and save periodcally, but after closing the file I can't open up. I get the message "Could not complete your request because it is not the right kind of document." I don't have any idea what may be causing this. IM using windows 7 If this is important or not and I started it on the same computer that I now have problems with. I'm not openeing another file type in photoshop in other words, it has been started and saved as a photoshop document and now it does not open. Please help if you have any suggestions, I'd be very happy. Thank you.

  Navigate to the file using windows Explorer and see what the extension is.

  which should be .psd or. PSD for a photoshop psd file. Sometimes the files may end

  to the top with two extensions, which confuses photoshop.

  Example: my file.png.psd

  Also you may need to enable display the extensions of the file types in the folder options.

  Try to open the file in photoshop by using file > open and choose psd.

• Why my file size results do not match between Photoshop and on my computer?

  I found something intriguing in CC PSD that I hope someone can explain to me.  I'm actually creating photo resizing tutorial and when I opened the picture in PSD I got these dimensions:

  

  But when the picture is turned on in Windows the size indicates a completely different size:

  

  I have advanced and resized the picture in PSD to 250 x 336 and reopened in PSD, it shows the size of the file to be 246K but in Windows and when clicked, it shows 130K so I don't know who is right now because they do not correspond to the top.

  If anyone has experienced this before?  Should I change something so that they match?  Please advise - thanks.

  I'm trying to demonstrate the importance of WHY you should not upload a photo which is 19 MB size

  Yes, we can all agree on that. But note that even if the pixel dimensions are reduced to an appropriate size (800-1200 pixels or so), the file size can always be a problem because of things like the metadata.

  So for use web, you should always use the new export function or save for Web in Photoshop. These will remove the metadata and also allow you to optimize the compression level so that you can arrive at a reasonable file size, for the given pixel size.

  Example image

  3504 x 2336 @ 240 ppi JPEG original image size now the size of the image is 3504 x 2336 @ 72 dpi.

  So, in my words, your picture has not changed somehow in Photoshop. There is no sense and doesn't matter the number of ppi. The important numbers are pixels.

• JPG file size inflated - Photoshop Document metadata: ancestors

  Has anyone experience this problem?

  I have a JPG file I have deleted all the image of and filled with white. When I save it, the size 7.89 MB. If I go into Bridge and clear metadata, probably ' < Document: ancestors > ' which contains ' RDF: bag <>"and 100 + lines of hexadecimal code, the file size down to about 150. Maybe I'm missing a file option on photoshop, but it seems that this metadata should be rubbed on the saved file. In addition, no one knows what kind of information is stored in the Document ancestors? Or if there is information from integrated image that could potentially be extracted?

  I was able to reach out to Adobe through my work. They mentioned that it was abnormal behavior so that there are over 100,000 lines of Document ancestors and thought it's maybe because it was a model. It turns out that a lot of the art I work with has lines of ancestors, and when you place them in a whole new file, this file becomes the. Many of these assets are CG renders, which too would be new files. While I don't know source of the Document ancestors, I could find a way to eliminate:

  function deleteDocumentAncestorsMetadata() {
      whatApp = String(app.name);//String version of the app name
      if(whatApp.search("Photoshop") > 0)  { //Check for photoshop specifically, or this will cause errors
          //Function Scrubs Document Ancestors from Files
          if(!documents.length) {
          alert("There are no open documents. Please open a file to run this script.")
          return;
          }
          if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");
          var xmp = new XMPMeta( activeDocument.xmpMetadata.rawData);
          // Begone foul Document Ancestors!
              xmp.deleteProperty(XMPConst.NS_PHOTOSHOP, "DocumentAncestors");
              app.activeDocument.xmpMetadata.rawData = xmp.serialize();
           }
  }
  //Now run the function to remove the document ancestors
  deleteDocumentAncestorsMetadata();
  

  Adobe has indicated that these were intended for the medical legal file and contained no sensitive information. I also tested this script with a loop provided in one of the Javascript reference Documents, and while it removes successfully ancestors without opening the file, it does not reduce the size of file until it is opened and saved again. So it must be run before you save on an open file and fit easily in my save scripts. Problem solved!

  If you are new to scripting, copy the lines above in a text of the document (no formatting as it can not work) and change the extension of JSX. From here in Photoshop, go to file > Scripts > Browse, locate this script to run on an open file. This can be tedious to do by file, so if you run on several, place the file in a fixed location and record an action that runs this script. If you don't know, once the script is saved you lot this script on the file navigation files > PLC > batch. Because the file needs to be saved to eradicate the ancestors of the document, I recommend pairing your script with a backup action as in a fixed location, as save in as long as actions will remember the folder you saved in.

• Can Photoshop Mix open a .psd file?

  Hello

  I m thinking about purchasing a Device IOS (iPad Pro) and the use of the Photoshop Mix for my work. I m looking for an application that is easy to cut out pictures of the products I sold, and then work with that image on a .psd file existing.

  I love the way that Photoshop Mix cut images, when I saw some videos about it.

  I now have an important question for me: I need to kow if, with this app, I'll have the ability to open a created previusly the .psd file and then insert the new cut picture created the Mix here.

  Many thanks in advance and sorry for my bad English! I hope you can understand me in spite of this!

  Hi Sergio!

  Thanks for reaching out. I apologize for the late reply! Yes, you can certainly open a. PSD file in the Mix and work with its layers. There are two ways you can go about it. You can send the image to Mix Creative cloud, cut out your picture and composite then it above a. PSD in the Mix. To get the. PSD in mixture, you must have Creative active sync (subscription cloud creative) and save it. PSD in your folder of Creative Cloud sync (probably on your desktop). From there you can put in the Mix (tap the sign + for a new composition, select creative cloud and access your PSD file). Or, you can cut out your picture and send it to the desktop version of CC of Photoshop (you also get a subscription cloud creative). From here you can composite your new image on top of your. PSD in the full version of PS.

  I hope this helps! Let me know if you need anything that anyone else.

  See you soon!
