Can't find new photos.
I have a brand new (2 days old) MacBook Air, running 10.8.2. I successfully transferred all my files, photos, and settings from my old MacBook to the new one using the Migration Assistant. I have discovered that I can't "find" my newer photos anywhere! Today I took some photos, and transferred them from my camera to iPhoto. I can see within iPhoto that a certain photo has a name, i.e., DSC04245, but when I go to look for it in the finder windows, a search cannot locate it. I've tried the search function, I've tried going through all the files, but to no avail. The last roll number is there from before I transferred the file, but I cannot find the roll I just uploaded. The photos are there in Iphoto, but not in my computer files. What's changed? How can I find my photos?
MacBook Air, OS X Mountain Lion (10.8.2)
