When I left my last job, I had backed up everything on an external hard drive before returning the laptop. I even backed up the backup of the pictures of my dog. But somehow, I forgot to back up the filters I had created for the camera app. They were photoshop actions, and I forgot to export them...
So I spent the last 3 days recreating the filters. Actually creating them wasn't the hardest part. Organizing them in a way it makes sense as a package took the most time.
But end the end, it actually worked out better. There were some issues I had with the previous filters, but I was able to resolve them.
I guess things happen for a reason. :)
