Not being able to audit what you voted for after the fact is by design. Otherwise, it would make buying votes a viable strategy since you'd be able to show them who you voted for. Yes, taking a picture of the ballot is an option, but you can always ask for another ballot paper after you take the photo. Where I live, you're not even allowed to have a camera out in the same room as a voting booth for this exact reason. IMO the best solution here is to have electronic counting with an auditable and traceable paper trail as a backup. Every time I've voted for the past 10 years has been like this. First, I get a ballot paper from the front desk and stick it into an airgapped ballot marking machine. I then make my choices and the machine prints them onto the ballot paper. I'm able to read the paper and verify that it matches the choices I made. I then stick it into a separate airgapped ballot counting machine, which scans my ballot and deposits the paper copy into a sealed box. The entire process of setting up the machines, transporting the paper ballots, and reading the results from the machines is cross-checked and signed off on by volunteer poll workers from both parties.
