Hi, Was wondering if someone might be able to put some insight on the issue I am having. When exporting a jpeg and then a tiff file of the same picture from Lightroom Classic and color space is set to Adobe RGB, there is a very noticeable color shift between the two files and I cannot understand why. My monitor is calibrated and LR is update. I have been researching this and have not found an answer as of yet and am hoping someone might be able to enlighten me what the issue might be. Thanks so much.
 
Is you monitor capable of displaying Adobe RGB at 100% of the color space, and what program are you using to view the files? Is it color managed?

Yes, my monitor is capable of displaying Adobe RGB at 100% and also srgb and to view the pictures it will either be Nikon's ViewNX-i or from Windows 10's picture folder where the pictures are exported to.
 
Upload the JPEG and TIFF to Dropbox or similar and post the sharing link here. That will let us quickly determine whether the issue is inherent in the images or something particular to your configuration.
 
JPeg have color coded with 8 bits, while Tif can have color coded with 16 bits. This more precise color coding in Tif might lead to a small difference when the image is displayed.
 
Thank you for your reply. Apparently I am having a problem in attaching the files. I can insert the jpeg but not the tiff file because it says "image file type invalid". Apparently the jpeg file is 1.48 mb but the tiff file is 12.4 mb. How can I make the tiff file smaller for attaching? Sorry for not knowing how to do this.
 
You'll have to use Dropbox or similar, since I don't think TIFFs of any size can be attached here.
 
Ok, what is Dropbox and how do I find/use it? Sorry In this message I was tryiing to attached the files using insert image where both of the images are there but using attach files the tiff file is not there.
 
Dropbox, Google Drive, and Microsoft One Drive are all similar, with free accounts. You upload the files to the service; there will be a "share" button which you can click to get a sharing link you can paste here. Or you can use WeTransfer.com, which doesn't require an account. Click the "+" to upload the two files, then click the "...", select Get Transfer Link,and then Get A Link. Copy and paste the link here.

Thank you so much in letting me know how to do this. Sorry it took so long in attaching these files. I was having just a little problem in working this out but I finally did it.

Thank you so much for the clarification!! I re-exported these pictures in the different settings and yes, the tiff apparently was exported in ProPhoto which I didn't realize at the time and don't know when it was put to that. The ProPhoto export is really more like what was shot and I like that the best. Then that leads to another question . . . what should I be exporting in ProPhoto or Adobe rgb? I realize that LR's default is ProPhoto for editing so should it be set to that for export or Argb? My monitor is 100% Argb and that is what I am using for editing and 98% Srgb. Should I be saving these in jpeg or tiff? My printer is a Nec243W. I do a lot of my own printing.

But when these pictures go out to a commercial photo lab for printing what should I be editing/exporting in Srgb or Adobe, jpeg or tiff for saving?

Thank all of you for your input and for figuring this out for me. Much appreciated!!
 
If you send them to a commercial lab, then you will most likely send them as JPEG because TIFF will be too big. That means that ProPhotoRGB should not be used (because JPEG does not support 16 bits color). If you know that they are using proper color management, then send them an AdobeRGB JPEG. If you are not sure about that, send them sRGB JPEG.

Printing your own images is something you can do straight out of Lightroom Classic. There is no reason to export them first.
 
Thank you again. Ok, then sending them out to a commercial lab and they are using proper color management and it is edited in Argb and then exported in Arbg but as a jpeg won't that still be making a color shift? If so, how do I correct that? I am then assuming the same is true for Srgb/jpeg? I have been told when sending to a commercial photo lab that I will need their ICC profile to simulate their paper etc. What happens if I do not have or can get their ICC profiles, will there be a significant difference then without it?

I do print straight out of LR but I was inquiring for when I do need to export them for sending them to a friend, etc or putting them on my phone or photo frame. So how should they be exported per the previous message . . . (what should I be exporting in ProPhoto or Adobe rgb? I realize that LR's default is ProPhoto for editing so should it be set to that for export or Argb? My monitor is 100% Argb and that is what I am using for editing and 98% Srgb.

Thanking you again for the wonderful information . . . it is really helpful.

The significant difference in color you observe between the TIFF and JPEG is caused by using a photo viewer that is not color managed. Though the TIFF and JPEG were exported in different profiles, they are visually indistinguishable when using a color-managed viewer on a wider-gamut display. But if you use a non-color-managed viewer, the TIFF and JPEG will look much different (since the color numbers stored for each pixel are different).

The (poor) documentation for ViewNX-i seems to indicate that it is color-managed, but using the Windows built in Photos app is not color managed. Viewers on Windows that are color-managed include Photoshop, Lightroom, Bridge, Firefox, Ifranview, and Faststone (you need to explicitly enable color management in the last two).

If you do not know how the file is to be viewed or printed, then you should always stick to sRGB. I would only recommend an alternate color space when instructed to use it or when the recipient will know what to do with the file in that color space.
