Hi, some of my last photos are rejected because technical issues, like this one, could you please help me why, with this photo for example.
I guess that my photos loses quality when I upload it, but its just an assumption.
Hello, the blue in your photo is oversaturated and your photo lacks sharpness.
1st answer is that your colour temperature (White Balance) is off. It is too magenta (the snow shouldn't be a magenta colour) and the exposure isn't good. Due to the fact you're shooting against snow, this can throw the exposure off as well as the white balance. White balance is a technical issue.
The photo dosen't lose quality when uploaded.

And no, your pictures don't lose quality by uploading. They enter as is in the Adobe database. The transfer is a simple copy procedure with no parameter adaption and re-encoding.
