Hi.

When I upload my pictures to the gallery, it changes the pictures (to the worse). How do I disable this "enhancement"?

Here's an example: http://rakrul.grimtask.com/bilder/piwigo.png
The left side is a screencap from the gallery, with picture size set to Orginal. The right side is a screencap from irfanView looking at the picture stored on my PC. As you cansee, the original in the gallery is quite different than the file on my PC.

Piwigo version: 2.6.2

Hello
Piwigo does not change the original files by default. The only case is if you put a specific size after upload, in the Size management page, and if you have Imagemagik and if you 're not using the ftp upload

Geir · 2014-06-04 13:35:13

Sorry, I'm an idiot. I booted down the server I posted the example on (and where the gallery is and it's currently set to private), but it's up again now so the link I posted should work.

I haven't made any changes to the default sizes and I don't have Imagemagik. I uploaded the photos through the web-admin interface. Should I use FTP to upload instead?

Thanks for the responses so far.

do you have exif written? like a wrong ratio info
and where comes from the pictures? from /upload?

Geir · 2014-06-05 00:30:20

The exif is right, and corresponds with the pictures, but piwigo seems to add contrast and/or saturation. The pictures are uploaded from the camera to the PC, where I treat them with Lightroom before I upload to server. I don't remove the exif data because I need it.

oh I thought you were pointing the size...

Piwigo doesn't change the file as said in my first post. I have seen this in the french forum and I can assure you it was only due certainly of a cache
anyway... piwigo doesn't do anything and without direct link that will be hard to judge

Geir · 2014-06-05 12:47:26

Ah no, my problem is that it seem to modify contrast/saturation or something.

I made the gallery with the picture public here: http://photo.grimtask.com/index.php?/category/17 but as you don't have the original I'm not sure what you're looking for. I think my example shows it quite clearly? At first I thought it was due to scaling but even when the size is "Original" it's different from the original.

flop25 · 2014-06-05 12:52:33

the example shows that indeed but it was too in the french case I've told about. When severals users and I checked really, none have seen the difference, and the guy itself only saw the difference on his computer

just upload your original by ftp and give us the link!!

Geir · 2014-06-06 00:04:46

Ahem... Well I investigated further and apparently Lightroom was exporting it as 1080p pictures and when I just uploaded the file to the web-server (not to the gallery) it had the same problems/artifacts so piwigo is certainly not to blame.

Sorry for wasting your time and thanks for the responses! :)

thx for reporting. I will to the french guy that we might found a explanation

Geir · 2014-06-06 01:27:41

This seems to be caused by the jpg-viewer in Chrome though. If I view the picture in the browser it's worse than with IrfanView, but I have no idea why. If you look at either the original in the gallery (http://photo.grimtask.com/upload/2014/0 … 5c4abc.jpg) or on the web-server (http://rakrul.grimtask.com/bilder/IMG_2275.jpg) you can see that it's actually worse than if you DL the file and view it locally or use e.g. IE.

That didn't work too well. Try this: http://bit.ly/TluFsJ

flop25 · 2014-06-06 13:23:31

I had issues too with the rendering colors between png and jpeg for safari/chrome vs the rest

try to change the color environment of the pics, and/or search/post on Chrome specific forums or on stackexchange
