I've been adding photos for over 10 years to iPhoto. Sorting years and albums into separate folders. I've been synchronising with my iPads.
After the latest update on Yosemite operating software, my iPhoto files are a mess and not properly represented. I am annoyed ... Is Lightroom a suitable alternative for a committed amateur like me ?
Software doesn't organize your photos for you ... you have to provide the organization. So ... the answer is that the software you choose isn't the issue, it's the amount of effort you put into organizing that is the issue.
If you put the time in, then ANY photographic organizing software will get the job done. If you don't put the time in, then NO photographic software will get the job done.
