EXIF info shows 1/125 shutter as 7.000

04 Oct 2009, 18:36

I'm using a Canon XSi, and if I display EXIF data the shutter speed displays incorrectly. For example, one image was shot at 1/125 (shown by Canon's DPP software) but Imagevue X2 displays the EXIF shutter speed as "7.000 sec". Am I missing something here?

Do you have a reference link to the image in mention so we can look into this?

Well, I missed that the first EXIF item is "Exposure" which shows the correct shutter speed. But the last EXIF item is "Shutter Speed" which is incorrect as I stated. What is that "Shutter Speed" supposed to be?

Also, I'm using "Auto" for text2 location and for horizontal images most of the EXIF info is off the screen with no way to see it. I tried other locations and only with the over_image locations is it always visible.

Exposure is not the same as shutter-speed. In technical terms, they call it "exposure-time", but "exposure" isolated, is the sum of all exposure factors (time+light etc). These are the settings we are reading from your file:

Here is wikipedia on EXIF shutter speed:
http://en.wikipedia.org/wiki/Shutter_speed

Now, I must admit 7 seconds seems incorrect for an image like that. We would have to diagnose this photo and see where that info is coming from. If its simply stored like that in the image, there is nothing we can do. A simple solution for you if you dont like it, is to remove the attribute from the EXIF data - Open the file imagevue/include/ivExifParser.class.php and comment out the shutter-speed setting.


Regarding the text placement locations - There are MANY placement options in Imagevue, and sorry they are not flawless, each for its use. The reason we placed EXIF data OVER the image by default in the first place, is because thats where it fits best. Not sure why you say "it is always visible"? By default, the data is only set to appear on image ROLLOVER. You have probably set it to appear static, and that doesnt look good when it appears OVER the image of course.

You cant set such text-blocks to "auto" and expect it to appear perfectly above on on the right of the image, where sufficient space is simply not available!

Yep, I understand. It would be good, though, if when the EXIF info extends off the screen that the appropriate scroll bar would appear to allow you to get to it.

Re the Exposure/Shutter speed. The actual shutter speed was 1/125 sec, as correctly displayed by the "Exposure" item. I guess I'll just remove the Shutter Speed item because that 7 seconds doesn't relate to anything I can think of.

Unfortunately EXIF we haven't fully deciphered yet, when reading info from file we're getting some crazy fractions like 35566667/34534554, sometimes they look okay after denominating them, but sometimes (looks like its camera-maker related) results vary.

Yeah, I'll bet the different camera makers have their own versions of EXIF.
