Sometime back i synced my IPhone with Google photos and all my photos where mixed up. It was difficult to identify the photos worth storing and those that can be deleted. What i found was there is no way to search for all photos based on certain criteria and i ended up doing below.
500 photo limit for Album
– This limit is only on number of photos that you use to create an album of move to album. So you can start creating album with 500 photos and then keep on adding photos to album i guess upto 2000. Remember the batch size should be 500.
Searching based on camera
– Try camera=
