#359283 Geotagging and depth in pictures' EXIF data

Posted by FanchGadjo on 27 March 2015 - 04:48 AM

You are right, I should not overcomplicate things. Most of the time, dives require

a single GPS point.


Sometimes, we enjoy drift diving in the English Channel. I would match a track

from the boat GPS system or a smartphone to the pictures.


I really need to find time to program a LR plugin to read a divelog and do the

tagging !

I manually edited a GPX file, after CSV conversion. I changed

the elevation in Excel and then converted back to GPX :



If one can get a column with the depth out of the dive log and

a time reference, it should be doable to fill out the corresponding

timestamps to match the GPX format.


Here is my underwater picture taken at -21 meters ! ;)

Hi there,

I use EXIFTool to set the focal length and other information about

the manual lenses that I use, but I never used Geosetter.


If you are into programming, there might be a way for matching 

and synchronizing your divelog to the GPS tracklog. I just discovered

this program : Subsurface Divelog. It will allow you to link pictures

to your dive and therefore have the depth information.


Have a look at the user manual, section 4.5 :



They suggest using your technique to synchronize the time data. ;)

I am installing it right now !!! :D

Great video ! I like the clean backgrounds.

It is beautiful to see them 'graze'.


Do you have an additional wet lens, or only 100mm macro ?

Bill, thank you for showing us your prototype results. It looks good !


Steve, your crabe picture is really good. I think this example is very well

suited for a quick "content aware filler" processing in photoshop for the

I would also use Magic Lantern. I have used stable releases and nightly builds

on a 550D and never had a problem. Moreover, I think it is far more convenient

to be able to set all your timelapse parameters from the camera controls, instead

of using a circuit board that you will probably fire as you close the housing.


Regarding 1D-X, you will probably need to go for an external circuit as there is

no "hack" or firmware overlay.
