File format use for saving file after eating a raw file in extension

Can someone explain the below please.

1) Open raw via Apple Photos and go to edit module where it opens as a raw (nef in the instance).

2) Open in Intensify extension. Edit and save file.

3) Saved file whilst still in the Photos edit module shows is as a jpg in the title. Right click on image and go to Info and is shows it as raw

4) Close edit module and look at file in Photos browser and it becomes a raw file (in the title and info) again and with all recent edits in place.

5) Open raw file again in edit module and it says jpg (but Info says raw)

What is going on? Any ideas? Is it jpg or raw or is it just reading the jpg info in the raw file? Or is it a big. My ideal would be for the raw to be preserved in both original and edited form our at least for edited to be tif.

Thanks

Don't worry about it. Photos has to save preview jpegs to view your edits from the RAW.

When I edit a RAW file using a Photo Editing Extension like Intensify, I noticed that Photos will create a very high quality JPEG, three times the file size of the original RAW file, and this JPEG will be passed to the app extension and return the edits. This JPEG is stored in the Photos Library in the folder Photos Library.photoslibrary/resources/modelresources/ in addition to the original Master image file. Successive edited will start from this new JPEG.

It will be discarded, when I use "revert to original".

Leonie, I am not sure Photos does that, it might well be Intensify for when Intensify works with Lightroom it converts the raw to a TIFF and then returns the Tiff to LR to store alone with the original RAW. In this case however the JPG returned to Photos is a jpg if you l;look at the label when in edit mode but raw if you look at the file info in edit mode. In browse mode the image is raw.

Just tested this with an 18.3mb raw file. Edit in Intensify and it sent back what the label says is a jpg. Looking at the Info the file is still an 18.3 mb raw.

So does that mean the jpeg I am seeing is just a reflection of the raw file that has been edited by the extension?

Photos will always keep the RAW original RAW file to preserve the lossless workflow.

I tested again and watched the files in the Photos Library with FindAnyFile, not the Info panel. My library is synced with iCloud Photo Library, so perhaps the working copies are different.

Before I open the Edit panel I am seeing a file P1180098.dng with 12.2 MB in the Masters folder, the original I imported.

As soon as Intensify is launched, I am seeing a new JPEG of 7.2 MB in the Modelresources folder.

When Intensify saves the results, I am seeing an additional new JPEG of 59.9 MB in the Modelresources folder. This file is showing the edits.

It is deleted, when I revert the image to the original.

Not using iCloud. But I start with an 18.3 mb raw, edit it and then end up with a second, edited, 18.3 mb raw. If I revert to original I lose the adjusted raw file and end up with the original 14.3 mb raw. So it appears I have two raw files. Equally if I elect to export the edited file I have an option of TIFF, JPG and PNG. Not sure why it would give any option other than jpg if the file is a jpg.

Where are you seeing the second RAW file? Are you seeing it o the disk or just in the info panel in Photos?

When I edit a DNG file or a Canon CR2 file using the Intensify extension, the Info panel in Photos is reporting the edited image as a RAW image, but all I can track down in the Photos library is the gigantic JPEG file. The original RAW file is unmodified, as it should be.

The photo is in my photo library on my mac hard drive. The only way I can se what is in it seems to be via Photos. What Photos shows is that the edited file is a raw file the same size as the original. If I "revert to original" I go back to the original unedited raw file. I am reasonably certain there are two files but I can only ever see one, the original or the edited. How can I see inside the photos library other than by using Photos itself?

Thanks for your help :-)

What Photos shows is that the edited file is a raw file the same size as the original.

The Info panel in Photos is showing you the attributes of the original file - RAW or JPEG, and the estimated size of the edited file when exported. It does not show the filetype of the edited file that the photo editing extension sent back.

I am using Find Any File to look into the Photos Library.

Download Find Any File here: The trial is free:

http://apps.tempel.org/FindAnyFile/index.html http://apps.tempel.org/FindAnyFile/index.php

FindAnyFile let#s you find files inside library packages where Spotlight will not search.

If you search with FindAnyFile for a certain image filename (without the filename extension), it will show you all working copies of this file inside your library, and you can see the files sent back from the extensions.

But be careful - just look, don't touch anything. It is easy to cause accidental damage. I'd make a current backup before poking around in the library.

Right-click (or Ctrl-click) onto Photos Library.photoslibrary and choose Show Package Contents. The originals are carefully filed away in the Masters folder.

But as Léonie rightly says, don't change anything. You do this at your own risk and you are advised to create a backup first.

Thank you to you both. It is a jpg.

This all just goes to show that Photos is no replacement for Aperture. It is there for the happy snapper/iPhone brigade. My testing of it stops right here and back to LR.

Many, many thanks

Colin
