Hello,
I run a gallery here: https://www.stefanhagen-fotografie.de
In the thumbnail view, everything looks alright. When you click on a picture it often gets desaturated. The color is noticeably different than in the thumbnail.
I have tracked this down to the following conditions:
* It happens in Chrome and Firefox (not in Internet Explorer)
* It happens when the "full size link" points to the picture directly, without the /render/ in the path.
For example check this picture:
Thumbnail: https://www.stefanhagen-fotografie.de/r ... e_0015.jpg (saturated)
Full size Link: https://www.stefanhagen-fotografie.de/c ... e_0015.jpg (desaturated)
You can check the Exif data by pasting the links to http://exifdata.com
This is what I think happens:
The imagevue resizer gets active when the /render/ is in the path. The resizer throws away the exif data, so every browser shows the image in the standard/native color space.
If /render/ is not in the path, the original picture is served to the client. The picture has the sRGB color space defined. Chrome and Firefox are interpreting a picture with sRGB differently than a picture without any colorspace definition. Therefore the difference.
One more thing...
I have noticed that "some" full size images are also resized using the imagevue renderer. What is the condition for this? Does this happen when I check the "resize" option when uploading?
I want to file this as a bug, because I think it should work consistently. Either the color-space of the thumbnail should match the color-space of the original. Or the color space of the original should be adapted.
Any thoughts on this? Am I the only one with this problem?
Best Regards,
Stefan
