ISO display with EXIF plugin
Hello All,
I ran into this topic because of a problem I experienced with the standard EXIF plugin I downloaded from Ghisler's website. It appeared that the ISO value of pictures taken with my Nikon D70 are NOT displayed. ISO values from 2 other camera's (Fuji film and A2) however are displayed properly. So it seems that the problem is related to the D70. The D70 pictures has Exif version 02(.)21
Is there someone who knows more about this? Perhaps already solved?
I downloaded and installed the latest (?) version of the Exif plugin (145), but that doesn't solve the problem. Hopefully, someone is able and willing to solve this problem, since the ISO value is very important to me as metadata of a picture. Of course I would like to deliver a D70 JPG file at your request. Thanks for your reply!
Regards,
Dick

It's possible that your camera stores the ISO value in a camera-specific part of the EXIF data. If this is the case, then my EXIF plugin will not be able to see it. It's also possible that it is using a different tag from the standard to store the ISO value. In this case it should be possible to extract it. Can you make a sample image available for testing? Please do not e-mail it to me, my mail server deletes large attachments.

ISO in EXIF Nikon
Thanks for your reply. I am quite sure that it has something to do with the way Nikon stores information in the EXIF header. I searched the Internet about this issue and found a considerable number of items where Nikon is cursed because of the way they store certain information items, like ISO/Sensitivity and exposure compensation. Most programs cannot handle this information and will even delete this info after editing (like Photoshop!)

Thanks and regards,

Irfanview cannot find any ISO ratings either (it can in some other files which I have). I haven't checked your file in a debugger yet, though, so I cannot say more. Here is the info from Irfanview:

cPicture shows ISO 400 - same as xnView.
The ISO tag is part of the camera manufacturer information (the blue section)!

Thank you all for your contribution. It's quite clear that Nikon puts the ISO setting in the vendor specific part, while they should (also) put it in the ISOSpeedRatings tag. Anyway, it would be nice if someone is willing and able to implement (at least a part of) the Nikon specific items in the EXIF plugin. The best solution for me is that I write a program which converts all my Nikon files to a more standard JPG_EXIF format, since programs I am using are destroying part of the EXIF header. But hey, I am not a programmer nor a whizkid, so that will take some time. Shame on Nikon.
Regards,
Dick

That's what I feared - these manufacturer informations often vary even between camera models of the same vendor, so it would ve very hard to support them - especially because they aren't well-documented.

Hopefully titanium is still reading this thread. I will try and email him too at the address he provided almost 2 years ago
I found a problem in the exif plugin.
I use Canon's ZoomBrowser EX (actually CameraCapture) to insert comments into captured images. Using exifer I can clearly see the embedded comment in the EXIF "image comment" field, but there's no such field in the EXIF plugin, there's a "ImageDescription" and a "UserComment" but no "ImageComment". OTOH exifer has niether UserComment nor ImageDescription in its list of supported fields.
Anyway, ZoomBrowserEX and Canon cameras are so popular that it would be very useful to fix this problem in the EXIF plugin. Thank you.

Hi, I just reinstalled this great plugin for some real date sorting options for renaming when I discovered that when having a slower shutter speed value than 1 second the plugin displays it as 1/0 despite it being maybe 15 or 30 seconds. I use that when shooting the milky way or similar scenarios.
Total Commander and Gaming. Only reasons left to use Windows.
There is a calculation bug in GPS Latitude/Longitude String and Floating representation in exif.wdx 2.3 due to minutes still being fractional.
See example: Image: http://tbeu.de/forum/exif_gps.png, Image: http://tbeu.de/forum/exif_gps_xnview.png
From the exiv2 dump the following entries can be read
The exif.wdx calculates 46.477 = 46/1 + 2831/100/60 + 31/100/60, hence seconds are added twice. Correct result should be 46.471833 = 46/1 + 2831/100/60 + 0/1/3600. I propose to fix the minutes to be non-fractional.
See example: Image: http://tbeu.de/forum/exif_gps.png, Image: http://tbeu.de/forum/exif_gps_xnview.png
From the exiv2 dump the following entries can be read
Code: Select all
0x0002 Exif.GPSInfo.GPSLatitude Rational 3 46/1 2831/100 0/1
0x0004 Exif.GPSInfo.GPSLongitude Rational 3 8/1 3156/100 0/1

I don't quite understand. Do you mean that the seconds are already part of the minutes field?
