I hope people realize that everyone is seeing something different.
It starts with how the photo was taken - the lighting conditions (and color temperature of the light), the direction of the light and shading, the sensor (or film in the old days), and much more.
The next step is converting the image from the sensor to a file, which involves computer processing. At some point, the photo becomes a computer file - a very long list of 0s and 1s.
The image you see also depends on how your system processes and interprets that file before sending it to the display. There are many kinds of displays, of course. After that, the ambient lighting around the display and your eyes/brain affect how you interpret what is on the screen.
It is possible to identify woods by posting images in a forum. More often than not, the results are an educated guess at best.
