I can NOT believe that I did this... I shot about 100 images on today's ride. Some of them came out very nicely too. I looked at them while they were on the memory card, then I began to process them in Photoshop. I shoot in the "Raw" format, and need to adjust levels, crop, etc., and then convert then into .tif format. I did 5 images, then broke for dinner. After dinner I sat down at the computer to finish the work, but notice that I had left the memory card still plugged into the card reader. I took it out, put it back into the camera, and as I always do, re-formatted the card, clearing it for the next days work. I went back to the computer, opened Photoshop, went to the drive where I saved the raw files... Oh oh... I didn't save the raw files. But I ALWAYS save the files before I work on them... Not this time. I was working on them and saving them back into the memory card... The same memory card that I just formatted... I can NOT believe that I did this to myself. Thank God there are recovery programs to protect fools such as me!
