subsecond exif data?

<p>Does anyone know if Nikon stores subsecond times in the exif data anywhere? On several occasions when looking at shots from a sporting event, I'll have several shots in a one or two second period and I'm curious how far apart they really were, but I haven't been able to find (using exiftool) anything better than 1 second resolution time stamps. I'm using a D90.</p>

<p>perhaps it depends on how much of the exif spec the camera implements. there is a series of subsec fields which *can* contain that information. whether the camera fills them out is another question.</p>

<p>in the terminal, do something like 'exiftool <name of image> | grep -i subsec'</p>

<p>although, if you shoot w/ a GPS receiver and geotag each shot (indoor sporting events may not work w/ that), you may be able to get subsecond accuracy as output from the GPS</p>

<p>to only view exif data, i use exiftool with the GUI add-in. it gives creation time/date in the format:<br>

2009:11:29 11:26:12<br>

i'm virtually certain you can obtain the same result.<br>

greater precision is available with the metadata information in ViewNX -- it goes to hundredths of seconds.<br>

either way, the info you seek is at hand.</p>

<p>GPS probably won't help here, unfortunately. The "GPS Timestamp" EXIF field only has one second resolution (with the Nikon GPS unit on the D3s and D3x, at least).</p>

<p> </p>

<p>exif *can* do it as there are fields defined for it. here are the relevant tagnames from exiftool -list. </p>

<p> SubSecCreateDate SubSecDateTimeOriginal SubSecModifyDate SubSecTime<br /> SubSecTimeDigitized SubSecTimeOriginal SubTileBlockSize SubTitle</p>

<p>It looks to me like the D90 always stores "00" for the sub-second values. This isn't true for all Nikon DSLR's though. Here is a random sampling from samples I have handy (table of SubSecTimeOriginal and Model information):<br>

<p>Thanks all. I had found three "Sub Sec" fields but on my example shots, which have the same time to the second but are obviously sequential, these are all zeros.</p>

<p>William, I might try ViewNX. Which camera are you using?</p>

<p>OK, I tried ViewNX, and I still get zeros. I did go back to an older gallery of D50 shots, and sure enough, just like in boardhead's data above, the D50 recorded decimal 1/100s, but apparently the D90 for some reason does not. The D90 has never received a firmware update, so nothing I can fix there. I'm giving up on this quest. Thanks again folks.</p>

<p>I remember reading a lengthy discussion about this issue and the result was - no they don't (or at least not accurately). That was before the D300 so it might have changed in the meantime. I also don't remember who got this result and how, so don't quote me on this.</p>
