I took a photo and I can see it on my camera's display but when I try to look at it on my computer using a CF card reader it's just black. I use a Mac Book Pro. I have tried opening with Lightroom and it sees the photo but won't import it saying it's an unrecognized file. Now for the weird part. I imported it using The Apple Photos app and it did it.... and then turned it immediately to black! What's going on? This photo is on a CF card.
