EXIF problem

[ace]

I'm running PP 1.5... but my EXIF data is all messed up...
see here...

the focal length is being expressed with too many decimals...
as far as I could tell, no one has actually presented this problem yet, if so, please help me fix it..

Pixelpost 1.6 will have improved EXIF support.
And it the final version of 1.6 should be out within a week or two.

So just hang tight for the moment, help is on the way. :-)

it is a well known ISO bug. Apply this fix:

My solution is to do this in line 397 of exif.php, last line in this snippet (in formatData method):

PHP Code:

    } else if($type=="USHORT" || $type=="SSHORT" || $type=="ULONG" || $type=="SLONG" || $type=="FLOAT" || $type=="DOUBLE") {
        $data = bin2hex($data);
        if($intel==1) $data = intel2Moto($data);
        if($intel==0 && ($type=="USHORT" || $type=="SSHORT")) $data = substr($data,0,4);
        $data=hexdec($data);
        // add this line here!!
        if ($tag="8827") $data=65535&$data; //mask 2 bytes for ISO rating 


(Mask ISO data with 0x0000FFFF)

Add this line: if ($tag="8827") $data=65535&$data; //mask 2 bytes for ISO rating

I appreciate it... but my problem isn't with ISO display... its with aperture display. I'm not good at reading/writting code, but this seems to be something that'll correct ISO readings....
Am I missing something? Perhaps should I change something in the code to deal with it...? if so.. what should I change?

try upgrading to version 1.6 final and see if the problem persists.
