EXIF. Intermittent Problem.


2 Feb 2019 3:43PM
I've been having a problem with EXIF data attached to images uploaded to the gallery. Most of the time the data appears with the image, but two images out of the last five required me to enter the information manually. None of the images are composites and all were processed in a similar way, using Photoshop and/or Nik Efex Pro. Anyone got any ideas.
Thanks
Alan

Quite often the 'jpeg save' can strip out the exif so it may be an idea to check your settings in whatever photography processing programme you use.

"Save for web" strips exif, but I have nor heard of any other ways of saving which do that.
When finished in Silver Efex, do you then flatten the image, or save it with layers? Could be that if you don't flatten the layers before saving then that can affect the exif? Just a thought...

I never use the "Save for web" option Malc. My workflow is always more or less the same for each image. My last upload, "Eight Ounces" is a typical example. Raw file opened in Canon DPP4, basic adjustments made, then converted to TIFF. TIFF opened in PS, some further enhancements, contrast, saturation, sharpness, some dodging and burning, basic stuff really. If converting to B&W I invariably use Nik Efex, as a plug in to PS. Once I'm happy with the image, I flatten all layers and then save as a Tiff, for archiving, and as a JPEG, in a separate folder, for uploading or printing etc. This process is, as I said, invariably the same, and yet some files, both Tiffs and Jpegs, have the Exif data embedded, and others do not.

Hmmm...strange. You have the same workflow as myself, Alan, yet I cannot remember having an exif problem.

Hi,

I've taken a look at the original file uploaded and the camera/lens exif info isn't there. There's the info from Photoshop and thats it I'm afraid, so it looks like somewhere along the line your workflow is stripping it out I'm afraid.

Thanks,

Karl

Couple of points - Saltireblue - 'Save for web' is no longer available on PS CC.

To save the metadata (exif) there are a couple of boxes which should be ticked in Preferences - Edit>Preferences>History Log the box to include metadata should be ticked, Edit>Preferences>Export the Metadata box should have the 'Copyright and Contact info' showing.

If you are using any other software to save images check with the software that it isn't set to remove exif as there is usually a choice.

Save for web does exist in Photoshop CC, you have to click on Export then you have the option for Save for Web.

Strangely I have never encountered an issue with exif data being stripped either creating a jpeg or creating a saving for web jpeg

Save for web under Export is a legacy choice by which I would assume you have to have Legacy ticked.

I've just used "save for web" via the export box and it behaves exactly as it used to in earlier versions of PS.
EXIF was to be removed by default but there's a drop down with alternatives including "all".
I assume that the "legacy" bit simply refers to the "save for web" option having been carried over from those earlier versions.
There was no box to tick that I could see.
Not that that's any help to anyone that's finding the EXIF removed unintentionally.

The legacy box is within the preferences (Edit>Preferences) so maybe you have already ticked it or it is as you suggested and it is assumed that you wish to use it.

I still can't find a box to tick but I have found out what the "legacy" tag means.

And it's not what either of us thought.

That's what I thought it meant. There have been a couple of tools which have been 'disappeared' but the latest 2019 download doesn't seem to work for everyone and the answer is to 'click the Legacy option'.

There are two instances of a Legacy box to tick in 2019
Edit>Preferences>General>Options>Legacy
and
Edit>Preferences>Performance>Options (at the bottom)>Legacy Compositing.

Yes, I've seen them and neither are ticked.
Since "save for web" comes with its own "(legacy)" label, presumably there's no box involved.
Either way the alternative "export as" dialogue seems to offer all that you need in its stead.

Thanks for all your comments guys, I've managed to figure out the problem and it's got nothing to do with "save for web", "legacy" or otherwiseSmile

During the editing process, if I wanted to convert an image to B&W, I had made a copy by using, "select all", "copy" and "File-new image from clipboard". It is at this stage that the Exif data was lost from the image.
