EXIF data partially corrupted
Posted: Mon Apr 19, 2010 5:58 am
Hi all, the problem I've encountered is the following.
The EXIF data in the output image is changed, but only some of them. The best is to look at an example.
Before Neat Image, original data:
<exif:ExposureTime>1/400</exif:ExposureTime>
<exif:FNumber>56/10</exif:FNumber>
<exif:ShutterSpeedValue>565248/65536</exif:ShutterSpeedValue>
After Neat Image:
<exif:ExposureTime>111848/44739201</exif:ExposureTime>
<exif:FNumber>11744051/2097152</exif:FNumber>
<exif:ShutterSpeedValue>69/8</exif:ShutterSpeedValue>
Numerical changes:
0.0025 -> 0.0024999...
5.6 -> 5.5999...
8.625 -> 8.625 (no change, but different fraction)
This is a minor problem but the fact that Neat Image changes the data is strange and unneccessary. Has anyone else encountered this? Devs, please investigate it! Thanks!
As input image I tried: jpeg from Canon XSI, jpeg from DPP, tiff from DPP.
As output image I tried: jpeg, tiff.
System: Windows 7, Neat Image 6.0 Standalone
