I accidentally lost 3 weeks of photos, how do I recover them?

Yikes, you might need a PC & data recovery app to see what might be on the SD card.

Don't take any more pics using that card, it'll make fewer deleted ones recoverable.

Sorry, that trash from the SD card, was not really on your Mac, but on the SD card itself. 😟

Well, if the Mac didn't overwrite them since the space was freed, then they may be recoverable...

Here's a free program called Mac Photo Recovery. http://www.flash-video-soft.com/photo-recovery/

If you have written more data to your hard drive, the old files may have been overwritten. The sooner you attempt recovery the better. If possible download the recovery program on another Mac and do the recovery attempt in Target Mode. Remember you will need a destination disk to store these recovered photos and that it may take several hours. I like to use an external drive to recover to.

Any REAL recovery tool is gonna cost money. Even the free downloads just let you preview the recovered photos, but won't go beyond that. .

Time Machine would only help you in the future. Is your Mac set up with Time Machine? If so you should be able to get the deleted files that way. Click the Time Machine icon in the dock. Then go back to before you deleted the files, they are probably still available. f you don't have a Time Machine backup yet, then your best option would probably be uFlysoft Data Recovery for Mac
