Before I can recommend a possible solution, can you answer these questions?
1. What is the reason why you need to recover the photos? Deleted, formatted, failed drive, etc?
2. Did you get a full sector-by-sector clone with which you are now working with?
3. What file system is on the client drive?
4. Do you plan to recover the data via Windows, Mac OS or Linux?
It's not same as other similar tool but outstanding and advanced in helping with dealing with deleted data, photos and other lost situations.
It's a free mac software for getting lost mac files back with easy operating steps. easeus data recover wizard for mac free is a brilliant helper for new mac users.

Though, there are many reliable data recovery software to regain Mac data but I recovered my lost data back from formatted drive upto 2 TB with Stellar Phoenix Mac Data Recovery software. One thing which I liked in this software the most is scanning the Mac drive completely bit by bit in Full Scan option.
You seem to be hell bent on pushing Stellar products. Have you posted about anything else?
