EE won't read EXIF if converted in PS with Adobe converter.

[melor]

EE won't mark as an EXIF containing file if converted in PS with Adobe converter. Pekka, I converted a picture in Breeze Browser and the EXIF is recognized with the little "X", but the same image converted in ACR in PS7 won't be recognized as EXIF. Many of the parameters are passed, i.e. Date and time, but is not "X"ed on the input line. Whatever you are looking for in the exif is not being found when using ACR. I can provide a file converted with ACR if you would like to look at it.

I did some more checking and found that the shutter speed is accurate if converted in BB, but not with Adobe Converter - ACR. This is the file:

Here is the original EXIF from BB:

Thanks for info.

EE uses now PHP's own EXIF reading system and finetuning that is out of my hands. So, one way to address these problems is to report them to PHP (and ACR) developers, and another is that I'll try to make ImageMagick to read EXIF and perhaps combine data found for complete information.

Paul,

I'm using a hacked version of ACR in Photoshop 7 on a Mac to process my Canon 10D raw files and the exif data is accurate and transferred properly in EE 1.5b4.

The crazy thing is that much of the data is accurate, the aperture, date, time, focal length of the exposure, only the shutter speed seems to be routinely bad. That and the fact that the little "X" won't show up during the input procedure.

Paul,

I guess I never looked for the little "x" during the processing. What does it mean? Here is the data from my ftp log for a recent upload of a 10D file processed with ACR:

I found a bug in EE's shutter EXIF speed conversion. I'll post a fix soon. Thanks for reporting!

[Pekka]

To fix the shutter speed problem, in ftp.php replace lines 162-180 (function fractionsplitdivider) with

function fractionsplitdivider($value) {
$values = explode("/",$value);
$a = 0;
$b = 0;
$a = @$values[0];
$b = @$values[1];
if (!isset($values[1])) return($value);
$div = $a;
if ($div == 1) return ($value);
if ($a != 0) $a = intval($a/$div);
if ($b != 0) $b = intval($b/$div);
$newspeed = "{$a}/{$b}";
if ($a == "0" && $b == "0") return("");
return ($newspeed);
}

[Pekka]

And don't worry about that EXIF's "X" not appearing. I know the reason and will fix that soon.

Pekka, thanks for checking the EXIF conversion. I wasn't trying to nit pick your code, but I figured it was a bug that you would be able to squash.

The changes made, will they be released in the next update? I can wait till then to use, or if you want me to test them, I can make the edit tonght.

No problem - all reports are very welcome, and they always make me check the code again, and this time I saw a bug there.

I added the fixes to ftp.php in http://photography-on-the.net/ftp_exiffix.zip for you to test.

Pekka, ran the update and tested with a new photo. Works better with shutter speed and "X" seems to be accurate. - Test was done with photo converted with Adobe ACR.

The lens prediction needs some help. It suggested my 2X converter was lens when I used 24-70 @ 38mm and the 24-70 is in the list.

I think I posted a list of Canon apertures for the dropdown as some were missing. Did you see it? I cannot remember where I posted it. It had the PHP code for all apertures at 1/2 and 1/3 stop settings.
