… However, be careful as you must always keep the original then do your modifications on a copy of the original. That way you can always start over.
Haven't we had this discussion previously???
Here's what I try to do consistently. I download pictures from my camera to my photo store on an external hard drive. I then discard any obviously unusable or unwanted photos. If there's any possibility I might want the photo at some time, I keep it. A
The remaining photos now go to the photo store on the hard drive of my computer. I file them by year and photo session (e.g., I have a 2008 folder, and within that 2008 folder are subfolders for each trip or activity I've undertaken when I took photos. When I transfer photos to my hard drive, I put them in a folder titled "unedited" within the folder for each activity.
When I'm ready to work on photos, I go through that "unedited" folder and select the photos I want to work on or keep. After I finish working on a photo it gets stored in a new folder titled "finished". I save most photos I work in both jpeg and PaintShop format - most of my editing is nondestructive editing using layers and masks, and that information is retained in the PSP format. Any photos that I want to save without editing get transferred into the "finished" folder as well.
When I'm done working on photos from a given activity, I go back to my photo store and delete all of the photos downloaded from my camera for that activity, and replace them with the contents of the "finished" from my hard drive. I do routine backups of my entire home network, and the photo store is included in that routine backup. The disk on which that backup is done is stored in our safe deposit box. One of our other computers has a second hard drive for general storage; I often do another backup there.
I leave the contents of the session on my hard drive as long as convenient. Generally if I start running out of room on my hard drive those old photo sessions are prime candidates for deletion to free up room.
This sounds complicated, but it really isn't. Once you go though it a couple of times it becomes pretty easy.
But if you don't institute a file management system for your digital photos, pretty soon you lose control of things. You won't know what photos you have stored where, which are backups and which are primary, and which are backed up and which aren't.
