I try to throw out as many near miss photos as I can.
We are always upgrading to new backup drives, but the cost still seems cheaper than the space I still use to store all my old negatives.
Our short term goal is to get a NAS server for the entire photo collection so that we may access them wirelessly and sort out the most likely to be valued over the years so they are easy to find and print.
BTW, "her" camera is an original Canon 5d and I use our Canon 5dmkII... we like having them because there are such nice lenses available for them.
The new Canon 6D is about to come out and it has great specs. In the meantime the 5dmkII is dropping in price and is a lot of bang at the latest prices.
But then, the Nikon bodies make some Canon owners, like me, envious.
When you have a bunch of lenses you like it's likely you stay with a system.
It's never clear, to me, which compnay is in the lead at any given time.
We retired a 35mm Nikon FE and gave away the lenses when we bought the Canon full frame DSLR.
Now Nikon makes a real nice full frame body with excellent on board noise reduction processing.
I wish it was easy to use the lenses I have on either. :-)
best regards,
