Coming from an a6000 to an A7iv really opened my eyes in terms of how *inadequate* my current workflow is for managing my photos and storage space. I just finished a few days of bird photography with compressed RAW + JPEG, and I already filled up my 64GB card.
It's not that I'm running out of space -- I have an Unraid storage server for *backup* -- but it means that I have to actively empty my SD card every couple of days which is really inconvenient for me. Yes, the compressed RAWs are that big.
What's everyone's strategy here? Do you keep every single photo or do you aggressively cull your shots? Do you purchase the largest SD card possible to push back emptying the SD card to more convenient times?
I have a slightly different approach. Now you take thousands of photos and you don't go back to them. However, to come back, at the end of the year we do a review and print a photo album. There are such services and they are not expensive.
And the photos are on the PC and the backup disk anyway. I do not store on the card or pendrive. Too many such media have already failed me.
