I am wondering if there is something in the flight log data that indicates when a photo was taken? If so, you would be able to find the corresponding altitude reading. Not all that straightforward, but if it does record it, all the info would be contained in a single csv file that can be opened as a spreadsheet. If it is not recorded in the flight data, you could still refer the time the photo was taken to the spreadsheet to discover the altitude at that time.
This is the flight data in Healthy Drones, with photo data extracted from the data. Not sure where the recorded altitude comes from, but the csv contains data to 7 decimal places and the values seem to update often. It does seem to show the home point elevation being relative to sea level.
Looking at the csv data, it does have a column marked isPhoto. There is a 1 recorded when a photo is taken, that row also contains the ASL altitude data, but you will have to subtract the (home) starting value to get AGL altitude.
Using Phantom Help, the csv contains altitude data to 1 decimal place, but home point starts at 0. Unfortunately neither have a column marked BAROMETRIC, so use your best guess as to where the data comes from.
