Resolution

Hello, The resolution is really confusing as each software reads different resolution. So I came up to set resolution the following way:

exiftool -photoshop:Xresolution=$resolution -photoshop:Yresolution=$resolution -jfif:Xresolution=$r +esolution -jfif:Yresolution=$resolution -XYResolution=$resolution $Myfile

Is this correct? Is there a better way? Am I forgetting another one?

Thank you in advance,
Laurent

Re: Resolution

Hi Laurent,

There is also EXIF:XResolution and EXIF:YResolution (which are actually the most commonly used values). And you can drop the XYResolution, since this is a proprietary Fotostation tag (unless you use Fotostation of course). Also, you must set the resolution units where applicable: EXIF:ResolutionUnit and JFIF:ResolutionUnit.

Re: Resolution

Thanks Phil,

Yes I have some people using Fotostation, some using Photoshop and some using software I don't even know. Both Mac and Windows. It would be great to be able to set the resolution for all at once ;-) For now I will add the exif related one. Is default Unit dpi if not set?

Re: Resolution

I don't think that EXIF defines a default (it is a braindead standard), so it is best to set it to "inches" explicitly.

Re: Resolution

This resolution thing is so useless but such a time wasting...

Thanks,
Laurent
