Hi. I've uploaded a few photos today and I am sure that the "Mindat upload system" makes them darker than they are. I am especially conerned about this one: https://www.mindat.org/photo-816793.html. Is there any bug within?

Best,

Luke K.

Had an issue with this image as well. Darker and off color.

It looks ok when viewing in Chrome. Problem appears when viewing the image in Firefox.

Not long ago, there was a discussion on mindat about this. If I remember correct it has to do with the adjustment of the camera or photo editing software. If the adjustment is set on AdobeRGB instead of sRGB this could be cause a colour shift.

Hi Lukasz

I have noticed a few very dark ones uploaded in the last few days - So dark I would not have approved them in the first place.
I use Windows, Chrome and Firefox as an alternate.

I cannot say that I have noticed Mindat making them darker. I think I would have to upload a photo personally to check this. I'll try on the when I am planning to take some photos.

Cheers

Keith

816793: can you post the original photo also in this thread, just to see if it appears brighter then?

Uh, uh, which one was it.... (-; Maybe this one:

sorry - will try to convert to JPG and upload it later.


I am sure the pics I have are way more bright that here on Mindat (or, rather/maybe, the Chrome/Firefox etc.?); I am uploading them also to Facebook, and they are OK.

P.S.: same problem today.

Some of my photos have come up a bit darker than set in the past, though my adjustments are usually pretty basic: cropping, brightness and contrast, never noticed an Adobe option.
