Fixed photos in LR are a combination of the original photo and any adjustments you’ve made that are stored in the LR catalog database as viewed in LR.
To see your fixed photos in anything besides LR or PS/ACR you need to export a copy, somewhere, then those exported copies will be new pixel values that represent your fixes.
LR is a non-destructive editor so your original photos don’t change.
k, tried the export, but the hundred photos I corrected aren't the ones that got exported...?
I imported 2 groups of pics (I think), and group 1 (who I can't find in lightroom and didn't correct) was exported, but group 2 (the ones I did correct) didn't get exported
You might want to spend some time learning how to navigate around and search for photos in the Library module. All of your photos are in your Library module somewhere, you need to find the photos of interest, select them and then export. Only the photos you select will be exported.
Are you looking for your exported photos in LR or on your hard-drive after Export?
When you Export a copy of a photo it doesn't not necessary also reside in the LR catalog but it does exist on the hard-disk. The exported copy of the photo is only in the LR catalog if you tell LR to do that as part of the Export panel options or if you Import it later.
I wouldn't suggest that you should include exported photos in the catalog because then it'll look like there are two copies. I would suggest that if you Export copies of your photos that you put them in a subfolder of the folder where the original photos are stored, so you can find them, later, outside of LR. There's no need to Export all your photos, just the ones you want to do something with outside of LR.
Instead of exporting 100s of photos, just do things with one until you figure out what you're doing.
Did not try to export my edited in Lightroom images. I did go to a folder in "My Pictures" and put all of the same images into a folder. Then I went back to Lightroom to export some of the edited images to that folder and got a message that the file is missing and I can no longer edit it. I can find the images in Lightroom under Missing photos, but cannot do anything with them. How do I restore the images to editable and export status in Lightroom?
