Question

error opening tiff file 2.2gb and 30,000 pixels

I know there is a 2gb and 30k pixel limit on psd, but I want to open my tiff file and save as psb.

But it won't open.

Anybody got a fix?

fyi this is a saved tif file from an Epson V800 scanner.  Can't save as psd or psb...

Thanks!

you can save a large tiff as a psb but yes, by design Photoshop assumes psd and will block a file bigger than 2G... the work around is to open Photoshop, create and save a new blank doc as psb then open that and 'place linked' the tiff file

 

however large files cause other problems and should be avoided when your work flow allows it

Thanks Ussnorway! I'll try this!

 

What worked best for me today was to crop out the black film guide and do a tight 6400res scan of my 4x5 film. File size was 1.96gb and the tif file opened just fine.

    Unfortuately, this did not work for me.  I got the same error messsage as before.

     

    Thanks anyway for the suggestion.

    So, I partially solved this problem....and confirmed file size is the issue.

    I rescanned one of the sheets of 4x5 film at 6000dpi instead of 6400dpi which produced a slightly smaller file in both the largest pixel dimension (28,xxx instead of 30,000+) and 1.9gb instead of 2.2gb.  PS 2021 opened this slightly smaller file with no problem whatsoever.

    But I would like to scan at a higher resolution, open in PS, then save as a psb file.  Epson Scan will not allow saving in a lossless format other than tiff, and PS won't seem to import tif files larger than 2.0gb or 30,000 pixels.

     

    There seems to be an assumption that psb files will be created by importing smaller files and increasing the size during the editing process, making the file bigger and necessitating saving as psb instead of psd.  But what if you are starting with a bigger than 2.0gb file and need to open it to get started editing???

    Does anyone have a workaround for this?

    Thanks!

    You are assuming this is a Photoshop bug, and it might be that. But there is another possibility: that it is an Epson Scan bug. (That is, when scanning to a TIFF that needs to be more than 2GB, that the TIFF is wrong). Can you open that TIFF made by Epson in any other app ok? Worth checking for Epson updates too.

    Thanks for your reply.  I'm not assuming this is a PS bug; I'm actually hypothesizing it is not a bug at all, but a design limitation.  It is well known that psd files cannot exceed 2.0gb or 30k pixels.  That is the reason psb format was created--to get around this design limit in psd files.

     

    tiff files are limited to 4.0gb.

     

    The problem--it seems to me--is that PS may limit the incoming size of tif files to 2.0gb or less--similar to psd format. But I don't know for sure if that is true, it just matches my trial and error experiments so far.

     

    I will happily try opening my 2.2gb tiff files in some other program if anyone can suggest one they know for sure will open tif files that exceed 2.0gb!  [I've tried a few; haven't found any yet--Windows Pic Editor, Paint, etc..]

    What is the full error message when you try to open the larger file?

    Can any other app open it?

    Can any application open it? Is it good or corrupted file?

    I don’t believe the file is corrupt. It’s every one of 8 similar scans I did today, while all 200 1.3gb tiff files I’ve scanned in the past few weeks open with no problem.
