In my iPhoto '11 database, I have 11+ years worth of digital photos well into the tens of thousands. A good percentage of those photos were taken portrait style, and of course I simply rotated them in iphoto to make review easier. As we know, iphoto retains a copy of the original photo if any there is any editing done. I understand the value of this feature for more "invasive" edits, but in the case of a simple rotate, there is no reason to keep two copies of what is essentially the same photo. I'm trying to pare my iphoto library down to a smaller harddrive footprint, and I'm sure deleting the originals (in the case of the rotate edits) would reclaim a substantial amount of space. What is the safest, most effective way of doing this? The only real editing I do via iphoto would be the rotate. Any other more substantial editing is done via an export and 3rd party software. Thanks!
