Hybrid wolf shot and killed near Denton. (UPDATED)

phantomlizzy - color and tone differences could be from the angle of the light vs. camera angle, exposure, white balance (with digital cameras), uncalibrated monitors (although maladjustments would be consistent on the same monitor), and software used to process, or even to post the photos.


Some examples of how even very simple variations can look: (I did these intentionally, but differences in monitors, software, etc., can do this without intentionally altering anything).

  

Auto-exposure can lead to vastly different tonal values of the same subject in the final exposure.  Auto-white balance can cause differences in values between multiple exposures of the same subject from different angles or under different lighting.  For example if a cloud passed over it would change that value, if the photographer moved so he/she was shooting the subject with the light source at a different angle a lot can change.  A lot of variables.  The lens itself wouldn't change those values, but when changing from one lens to another it might, due to the lens characteristics.
